Background
Global warming has become one of the biggest environmental threats facing mankind in the world today. Cities as economic activity centers of production and life are main sources of energy consumption and carbon emission, so the cities are also important carriers for realizing carbon peak reaching and carbon neutralization targets. The carbon neutralization of cities is realized, the greenhouse gas emission needs to be reduced by adopting corresponding policy measures and technical means, and when carbon reduction policies and measures are implemented, the carbon dioxide emission and future trends of the cities need to be accounted and predicted, so that quantitative basis is provided for the formulation of carbon neutralization policies and routes.
Transportation is an important carrier of urban energy consumption and also one of the main emission sources of urban carbon emission. In order to better establish a corresponding carbon reduction policy for transportation, the development of the transportation carbon reduction technology needs to account the carbon emission condition of urban transportation. In the related technology, the traffic carbon emission accounting method mainly calculates regional traffic carbon emission from a macroscopic level and mainly calculates based on three parameters of average carbon emission factors of different vehicles, the holding amount of motor vehicles and the average driving distance of different vehicles. The partial accounting method further considers the factors such as the traffic flow of the driving road section, the driving state of the motor vehicle and the like at the mesoscopic level, further perfects the method for calculating the carbon emission of the road traffic, and improves the accuracy of the accounting of the carbon emission of the road traffic.
However, the method mainly performs accounting on the existing carbon emission data, lacks prediction on the future trend of the carbon emission of transportation, and cannot provide quantitative reference for future policy making.
In view of the above problems, the present application proposes a new urban traffic carbon emission prediction method, apparatus, electronic device and storage medium to at least partially solve the above problems.

Exemplarily, an exemplary electronic device for implementing the urban traffic carbon emission prediction method and apparatus according to the embodiment of the present invention may be implemented as a terminal such as a smartphone, a tablet computer, a desktop computer, or the like.
Hereinafter, a method for predicting urban traffic carbon emissions according to an embodiment of the present invention will be described with reference to fig. 2. Fig. 2 is a schematic flow chart of a method 200 for predicting urban traffic carbon emission according to an embodiment of the present application. The urban traffic carbon emission prediction method according to the embodiment of the present application is applied to an urban traffic carbon emission prediction apparatus, where the urban traffic carbon emission prediction apparatus includes a processor, a memory, an input device, an output device, and the like, and the urban traffic carbon emission prediction apparatus may be implemented as the electronic device 100 described above. Specifically, the urban traffic carbon emission prediction method 200 according to the embodiment of the present application includes the following steps:
first, in step S210, a city traffic carbon emission prediction model is constructed.
In the embodiment of the invention, firstly, a city needing to be predicted and planned for traffic carbon emission is determined, and after the corresponding city is determined, an urban traffic carbon emission prediction model is constructed for the city. According to the constructed urban traffic carbon emission prediction model, the urban traffic carbon emission value of the city in a certain year, a certain month and other time can be predicted.
Specifically, the urban traffic carbon emission prediction model may be constructed in various ways, such as according to the urban traffic situation, according to the type of vehicle and type of combustion, according to the type of traffic pollution, and so on. Taking the construction of the urban traffic carbon emission prediction model according to the traffic types as an example, the urban traffic types need to be classified, and after the classification is finished, the urban traffic carbon emission prediction model is constructed according to the classification result. Traffic types such as cities include public traffic and non-public traffic.
In step S220, historical urban traffic carbon emission-related data is acquired.
In the embodiment of the invention, the urban traffic carbon emission related data comprises a series of data related to the traffic carbon emission, such as the number of vehicles, the driving mileage, the energy consumption, the carbon emission and the like, and the future urban traffic carbon emission is predicted by acquiring the data. It should be noted that the history here refers to any historical time period such as a past year, a month, etc.
In step S230, a first type urban traffic carbon emission influence factor is determined based on preset influence factor parameters and the historical urban traffic carbon emission related data.
In the embodiment of the invention, the first type urban traffic carbon emission influence factor is calculated by combining the influence factor parameter and historical urban traffic carbon emission related data. When the future urban traffic carbon emission is predicted only through historical urban traffic carbon emission related data, the prediction can be accurate only when the development trend of the future urban traffic carbon emission is consistent with the past trend, and when the development trend of the future urban traffic carbon emission is inconsistent with the past trend, the prediction value is far from the future actual value, so that the prediction of the future urban traffic carbon emission through the historical urban traffic carbon emission related data has great limitation. By setting the influence factor parameters, the trend obtained by predicting the historical urban traffic carbon emission related data can be corrected, so that the predicted value is consistent with the future actual value as much as possible.
The influence factor parameters are related to the acquired historical urban traffic carbon emission related data and the first type urban traffic carbon emission influence factor to be determined. For example, when the historical urban traffic carbon emission related data is a historical motorization ratio of motor vehicles and the first type of urban traffic carbon emission impact factor is a future motorization ratio of motor vehicles, then the impact factor parameter may be a final value of the motorization ratio of motor vehicles when the urban traffic carbon emission reaches the urban traffic carbon emission target value.
The historical motor vehicle electric proportion can be determined according to the historical number of the electric vehicles and the number of the non-electric vehicles in the motor vehicle, and the final value of the motor vehicle electric proportion is preset. In one example, determining a first type of urban traffic carbon emission impact factor based on preset impact factor parameters and the historical urban traffic carbon emission-related data comprises: determining the historical motor vehicle electromotion proportion according to the number of the electric vehicles and the number of the non-electric vehicles in the historical motor vehicle; determining the future motor vehicle motoring rate as a function of the historical motor vehicle motoring rate and the final value of the motor vehicle motoring rate.
Specifically, the following formula can be adopted to calculate the historical motorization ratio of the motor vehicle:
wherein,motor vehicle motorization ratio, Q, representing history EV Number of electric vehicles in motor vehicles, Q, representing history FV Non-electric vehicle in motor vehicle representing historyThe number of the cells. Taking the calculation of a certain type of motor vehicle in a certain year in the past as an example, historical urban traffic carbon emission related data, namely the number of electric vehicles and the number of non-electric vehicles in the motor vehicle of the type in the current year, are firstly obtained, and then the number of the electric vehicles and the number of the non-electric vehicles are substituted into the formula, so that the electric proportion of the motor vehicle of the type in the current year can be obtained. Similarly, the proportion of the motorization of the motor vehicle in any other time period such as a month in the past can be calculated through the formula. The historical motor vehicle electromotion proportion in the city can be determined by calculating the historical electromotion proportion of all types of motor vehicles. Of course, the number of electric vehicles and the number of non-electric vehicles in all types of motor vehicles can be directly obtained and substituted into the formula, so that the historical motor vehicle electromotion proportion in the city can be obtained.
In calculating the historical motor vehicle electromotion proportionThen, will be based onAnd substituting the preset final value of the motor vehicle electromotion proportion into a corresponding calculation model to obtain the future motor vehicle electromotion proportion. In one example, determining the future vehicle motorization ratio based on the historical vehicle motorization ratio and the final value of the vehicle motorization ratio includes: selecting an S-shaped curve model; calculating the future motor vehicle motoring ratio by the sigmoid curve model based on the historical motor vehicle motoring ratio and the final value of the motor vehicle motoring ratio. In the example, the proportion increase curve of the electric vehicle is simulated by an S-shaped curve, so that the future motorization proportion of the motor vehicle is predicted.
There are many sigmoid curve models for selection, such as Logistic curve model (logic distribution cumulative distribution curve model), gompertz curve model (goberz curve model), weibull curve model (weber distribution cumulative distribution curve model), and the like. Taking the Logistic curve model as an example, the future calculation formula of the motor vehicle electric proportion is as follows:
wherein,representing the proportion of motorization of the motor vehicle in the future,represents the final value of the motorization ratio of the vehicle, n represents the number of years since the city possessed the first electric vehicle, and γ represents the slope of the curve.
For the slope γ of the curve, the motor vehicle motorization ratio can be substituted into the historyAnd the number of years n from the city having the first electric vehicle 0 Fitting is carried out to obtain that:
then, in step S240, a predicted value of the future urban traffic carbon emission is determined by the urban traffic carbon emission prediction model based on the first type of urban traffic carbon emission influence factor.
In the embodiment of the invention, the first type of urban traffic carbon emission influence factor is substituted into the urban traffic carbon emission prediction model, so that the future urban traffic carbon emission prediction value is obtained. When the first type of urban traffic carbon emission influence factor is the future motor vehicle electromotion proportion, the future motor vehicle electromotion proportion is substituted into the calculation factor of the urban traffic carbon emission prediction model, so that the future urban traffic carbon emission is predicted according to the future motor vehicle electromotion proportion.
Besides, a second type urban traffic carbon emission influence factor related to the first type urban traffic carbon emission influence factor can be determined, and the first type urban traffic carbon emission influence factor and the second type urban traffic carbon emission influence factor are jointly used as calculation factors to be substituted into the urban traffic carbon emission prediction model. In one example, determining a future urban traffic carbon emission prediction value by the urban traffic carbon emission prediction model based on the first type of urban traffic carbon emission impact factor comprises: determining a second type of urban traffic carbon emission impact factor, the second type of urban traffic carbon emission impact factor comprising at least one of: direct emission intensity of motor vehicles, electrical emission intensity of motor vehicles, number of motor vehicles in the future; determining the urban traffic carbon emission prediction value through the urban traffic carbon emission prediction model based on the future motor vehicle motorization proportion and the second type urban traffic carbon emission influence factor.
The second type of urban traffic carbon emission influence factor is also related to the historical urban traffic carbon emission related data, so the second type of urban traffic carbon emission influence factors such as the direct emission intensity of the motor vehicles, the power consumption emission intensity of the motor vehicles, the number of future motor vehicles and the like can be obtained by calculating the historical urban traffic carbon emission related data obtained in step S220.
In some implementations, when the second type of urban traffic carbon emission influence factor includes a future number of vehicles, historical urban traffic carbon emission-related data such as a historical number of vehicles, a historical vehicle consumption capability value, a flatulence index, a historical average vehicle price, an economic growth prediction rate, and a historical total average domestic production value may be acquired in step S220, and the future number of vehicles may be calculated according to the acquired historical urban traffic carbon emission-related data, thereby determining the second type of urban traffic carbon emission influence factor.
Wherein, when the type of the motor vehicles is a bus such as a bus, a taxi, a van, etc., since the number of buses is relatively stable in a city, it can be assumed that the number of such vehicles is not changed, i.e., the number of future motor vehicles is equal to the historical number of motor vehicles, where the future number of motor vehicles and the historical number of motor vehicles refer to the number of buses.
When the type of the motor vehicle is a private car, the holding capacity of the private car can change along with various influence factors such as the price of the automobile, the GDP (total production per capita) per capita and the like. Therefore, the number of the vehicles in the future needs to be predicted by combining historical data of the number of the vehicles and the like.
Illustratively, determining a future number of vehicles based on the historical number of vehicles includes: confirming a future automobile consumption capacity value; calculating a regression constant according to the historical number of the motor vehicles and the historical automobile consumption capacity value; and calculating the future number of the motor vehicles according to the regression constant and the future automobile consumption capacity value. In this example, a unary linear regression approach is taken to predict the future number of vehicles, and the historical number of vehicles refer to the number of private cars. In the process of confirming the number of the future vehicles, the step of confirming the future vehicle consumption capacity value and the step of calculating the regression constant can have a sequence, can also be carried out simultaneously, and the symmetry is not limited.
Firstly, fitting is carried out according to the historical number of motor vehicles and the historical value of the automobile consumption capacity to obtain a regression constant, and the following calculation formula can be adopted:
a=Q private car 0 /R 0
Wherein a represents a regression constant, Q Private car 0 Number of motor vehicles, R, representing history 0 Representing historical automobile consumption capacity values. R is 0 The total value, namely R, can be produced by historical average automobile prices and historical per capita domestic production 0 = historical per-person GDP/historical average price of car.
After the regression constant a is obtained, calculating the number of future motor vehicles by a unary linear regression mode based on the regression constant a and the future automobile consumption capacity value, wherein the calculation formula is as follows:
Q private car =aR
Wherein Q Private car Representing the number of future vehicles and R representing the future vehicle consumption capability value.
As for the future automobile consumption capacity value R, the future automobile consumption capacity value R can be obtained by calculation according to historical urban traffic carbon emission related data such as a flatulence index, historical automobile average price, economic growth prediction rate, historical domestic production total value of everyone and the like.
Illustratively, confirming future car consumption capability values includes: determining the average price of the future automobile according to the flatulence index and the historical average price of the automobile; determining future per capita domestic production total value according to the economic growth prediction rate and the historical per capita domestic production total value; and determining the automobile consumption capacity value according to the future average domestic production total value of everyone and the future average price of the automobile. In this example, the ability to consume cars by people is reflected by the average price of cars and the total value of domestic production by everyone. In the process of confirming the future automobile consumption capacity value, the step of determining the future average automobile price and the step of determining the future total domestic production value of everyone can have a sequence, can also be carried out simultaneously, and is not limited symmetrically.
The swelling index is also called the inflation rate, and refers to the rate of increase of the general total price level over a certain period of time (usually one year). In this example, the flatulence index may be chosen as a flatulence prediction index I issued for the city government. The formula for calculating the average price of the future vehicle (after n years) according to the flatulence prediction index I and the historical average price of the vehicle is as follows:
future average price of automobile = historical average price of automobile × (1 + I) n
The economic growth prediction rate is used for predicting the economic growth rate in a certain time in the future, and an economic prediction index x issued for the city government can be selected. The formula for calculating the future (after n years) total domestic production value of the everyone according to the economic prediction index x and the historical total domestic production value of the everyone is as follows:
future people GDP = historical people GDP x (1 + x) n
After the future average automobile price and the future total domestic production value of everyone are calculated, the future automobile consumption capacity value R can be further calculated, and the calculation formula is as follows:
r = future average people GDP/future average price of automobile
In some implementations, when the motor vehicle is a non-motor vehicle, the second type of urban traffic carbon emission influence factor includes a direct emission intensity of the motor vehicle, historical urban traffic carbon emission related data such as an average driving distance of the motor vehicle, energy consumption per kilometer of the motor vehicle, a unit energy consumption carbon emission of the motor vehicle, and the like may be acquired in step S220, and the direct emission intensity of the motor vehicle may be calculated according to the acquired average driving distance of the motor vehicle, energy consumption per kilometer of the motor vehicle, and the unit energy consumption carbon emission of the motor vehicle, so as to obtain the second type of urban traffic carbon emission influence factor. Specifically, the following formula can be adopted for calculation:
wherein,representing the direct emission intensity of the motor vehicle, D i Representing the mean driving distance, FC, of the motor vehicle i Representing the energy consumption per kilometer of the vehicle, CEF represents the specific energy consumption carbon emission of the vehicle. When the average driving distance D i The annual average driving distance can be calculated, and the direct emission intensity of the annual motor vehicle can be calculated; when the average driving distance D i The monthly average driving distance or the driving distance of other time duration, and accordingly, the direct emission intensity of the motor vehicle of the monthly or other time duration can be calculated. And because the energy consumption per kilometer, the carbon emission per energy consumption and the like of different types of motor vehicles are different, the direct emission intensity of each type of motor vehicle can be respectively calculated by adopting the formula and then summarized to obtain the direct emission intensity of the urban motor vehicle.
In some implementations, when the motor vehicle is an electric vehicle, the second type of urban traffic carbon emission influence factor includes an electricity consumption emission intensity of the motor vehicle, historical urban traffic carbon emission related data such as a unit electricity consumption carbon emission variation trend of the motor vehicle, historical unit electricity consumption carbon emission of the motor vehicle, an average driving distance of the motor vehicle, energy consumption per kilometer of the motor vehicle and the like may be obtained in step S220, and the electricity consumption emission intensity of the motor vehicle is calculated according to the obtained unit electricity consumption carbon emission variation trend of the motor vehicle, historical unit electricity consumption carbon emission of the motor vehicle, the average driving distance of the motor vehicle, and energy consumption per kilometer of the motor vehicle, so as to obtain the second type of urban traffic carbon emission influence factor.
Specifically, the unit electricity consumption carbon emission of the future motor vehicle is determined according to the unit electricity consumption carbon emission change trend of the motor vehicle and the unit electricity consumption carbon emission of the historical motor vehicle. Taking the energy structure adjustment of china as an example, the variation trend of the unit carbon consumption emission of the motor vehicle can be set to decrease by 2.4% year by year, and then the calculation formula of the unit carbon consumption emission of the motor vehicle (after n years) in the future is as follows:
CEE=CEE'×(1-2.4%) n
where CEE' represents the unit electricity consumption carbon emission of the historical motor vehicle, which is released by the country or the local place, and CEE represents the unit electricity consumption carbon emission of the future motor vehicle.
Then, calculating the power consumption emission intensity of the motor vehicle according to the average driving distance of the motor vehicle, the energy consumption per kilometer of the motor vehicle and the unit power consumption carbon emission of the future motor vehicle, wherein the calculation formula is as follows:
wherein,representing the intensity of the electrical emissions of the motor vehicle, D i Representing the average driving distance, EC, of the motor vehicle i Representing the energy consumption per kilometre of the motor vehicle. When the average driving distance D i The annual average driving distance can be calculated, and the annual power consumption emission intensity of the motor vehicle can be calculated;when the average driving distance D i The average driving distance per month or the driving distance of other time duration, and accordingly, the power consumption emission intensity of the motor vehicle per month or other time duration can be calculated. And because the energy consumption per kilometer, the unit power consumption carbon emission and the like of different types of motor vehicles are different, the power consumption emission intensity of each type of motor vehicle can be respectively calculated by adopting the formula and then summarized to obtain the power consumption emission intensity of the urban motor vehicle.
After the second type of urban traffic carbon emission influence factor is determined, a future urban traffic carbon emission predicted value can be calculated through an urban traffic carbon emission prediction model based on the future motor vehicle electromotion proportion and the determined second type of urban traffic carbon emission influence factor.
In one example, determining the urban traffic carbon emission prediction value by the urban traffic carbon emission prediction model based on the future motorization ratio and the second type of urban traffic carbon emission impact factor comprises: calculating the carbon emission of the electric vehicle according to the future electric vehicle motorization proportion, the electric vehicle power consumption emission intensity and the future number of the electric vehicles; calculating the carbon emission of the non-electric vehicle according to the future electric vehicle motorization proportion, the direct emission intensity of the motor vehicle and the future number of the motor vehicles; and calculating the urban traffic carbon emission predicted value according to the carbon emission of the electric vehicle and the carbon emission of the non-electric vehicle. In this example, the predicted urban traffic carbon emission values are summarized by calculating the carbon emission of future electric vehicles and the carbon emission of non-electric vehicles, respectively. In the process of determining the urban traffic carbon emission predicted value, the step of calculating the carbon emission of the electric vehicle and the step of calculating the carbon emission of the non-electric vehicle can have a sequence, can also be carried out simultaneously, and are not limited symmetrically.
Specifically, a calculation formula for calculating and obtaining a predicted value of the carbon emission of urban traffic in the future (after n years) according to the carbon emission of the electric vehicle and the carbon emission of the non-electric vehicle is as follows:
wherein GHG represents a predicted value of urban traffic carbon emission in the future,representing the future motorvehicle motorization ratio, Q i Representing the number of vehicles in the future, can be obtained by summing the number of public vehicles in the future and the number of private vehicles in the future,representing the direct emission intensity of the motor vehicle,representing the intensity of the electricity used by the motor vehicle.
Finally, in step S250, it is determined whether the predicted future urban traffic carbon emission value matches a preset urban traffic carbon emission target value, and if not, the impact factor parameter and the urban traffic carbon emission target value are adjusted, so that the predicted future urban traffic carbon emission value obtained based on the adjusted impact factor parameter matches the adjusted urban traffic carbon emission target value.
In the embodiment of the invention, the impact factor parameter and the urban traffic carbon emission target value are adjusted until the calculated urban traffic carbon emission predicted value is consistent with the urban traffic carbon emission target value, so that the urban traffic carbon neutralization quantification target can be specified according to the calculated urban traffic carbon emission predicted value, and urban traffic is subdivided according to the urban traffic carbon emission target value and the impact factor to carry out carbon reduction planning.
In one example, as shown in fig. 3, when the predicted future urban traffic carbon emission value does not conform to the preset urban traffic carbon emission target value, repeating steps S230 to S250, i.e. the adjusting the impact factor parameter and the urban traffic carbon emission target value, so that the predicted future urban traffic carbon emission value based on the adjusted impact factor parameter conforms to the adjusted urban traffic carbon emission target value includes: determining a first type of urban traffic carbon emission influence factor based on the adjusted influence factor parameters and the historical urban traffic carbon emission related data; determining a future urban traffic carbon emission predicted value through the urban traffic carbon emission prediction model based on the first type of urban traffic carbon emission influence factor; and judging whether the future urban traffic carbon emission predicted value is consistent with the adjusted urban traffic carbon emission target value, if not, readjusting the influence factor parameter and the urban traffic carbon emission target value, and repeating the steps until the future urban traffic carbon emission predicted value is consistent with the adjusted urban traffic carbon emission target value.

As shown in fig. 4, the urban traffic carbon emission prediction apparatus 400 according to the embodiment of the present invention includes a prediction model construction module 410, a historical data acquisition module 420, an influence factor determination module 430, a carbon emission prediction value determination module 440, and a judgment module 450. The prediction model building module 410 is used for building an urban traffic carbon emission prediction model, and the historical data acquisition module 420 is used for acquiring historical urban traffic carbon emission related data; the influence factor determining module 430 is used for determining a first type of urban traffic carbon emission influence factor based on preset influence factor parameters and the historical urban traffic carbon emission related data; the carbon emission predicted value determining module 440 is used for determining a future urban traffic carbon emission predicted value through the urban traffic carbon emission prediction model based on the first type urban traffic carbon emission influence factor; the determining module 450 is configured to determine whether the future carbon emission prediction value of the urban traffic conforms to a preset carbon emission target value of the urban traffic, and if not, adjust the impact factor parameter and the carbon emission target value of the urban traffic, so that the future carbon emission prediction value obtained based on the adjusted impact factor parameter conforms to the adjusted carbon emission target value of the urban traffic.

Only the main functions of the respective modules of the urban traffic carbon emission prediction apparatus will be described below, and details that have been described above will be omitted.
In the embodiment of the invention, firstly, a city needing to be predicted and planned for traffic carbon emission is determined, and after the corresponding city is determined, a city traffic carbon emission prediction model is constructed for the city. According to the constructed urban traffic carbon emission prediction model, the urban traffic carbon emission value of the city in a certain year, a certain month and the like in the future can be predicted.
Specifically, the urban traffic carbon emission prediction model may be constructed in various ways, such as according to the traffic situation of the city, according to the type of vehicle and the type of combustion, according to the type of traffic pollution, and so on. Taking the example of constructing the urban traffic carbon emission prediction model according to the traffic types, the urban traffic types need to be classified, and after the classification is finished, the urban traffic carbon emission prediction model is constructed according to the classification result. Traffic types such as cities include public traffic and non-public traffic.
In the embodiment of the invention, the urban traffic carbon emission related data comprises a series of data related to the traffic carbon emission, such as the number of vehicles, the driving mileage, the energy consumption, the carbon emission and the like, and the future urban traffic carbon emission is predicted by acquiring the data. It should be noted that the history here refers to any historical time period such as a past year, a month, and the like.
In the embodiment of the invention, the first type urban traffic carbon emission influence factor is calculated by combining the influence factor parameter and historical urban traffic carbon emission related data. When the future urban traffic carbon emission is predicted only through historical urban traffic carbon emission related data, the prediction can be accurate only when the development trend of the future urban traffic carbon emission is consistent with the past trend, and when the development trend of the future urban traffic carbon emission is inconsistent with the past trend, the prediction value is far from the future actual value, so that the prediction of the future urban traffic carbon emission through the historical urban traffic carbon emission related data has great limitation. By setting the influence factor parameters, the trend obtained by predicting the historical urban traffic carbon emission related data can be corrected, so that the predicted value is consistent with the future actual value as much as possible.
The influence factor parameters are related to the acquired historical urban traffic carbon emission related data and the first type urban traffic carbon emission influence factor to be determined. For example, when the historical urban traffic carbon emission related data is a historical motorization ratio of motor vehicles and the first type of urban traffic carbon emission impact factor is a future motorization ratio of motor vehicles, then the impact factor parameter may be a final value of the motorization ratio of motor vehicles when the urban traffic carbon emission reaches the urban traffic carbon emission target value.
The historical motorization ratio of the motor vehicle can be determined according to the historical number of the electric vehicles and the number of the non-electric vehicles in the motor vehicle, and the final value of the motorization ratio of the motor vehicle is preset. In one example, the determining a first type of urban traffic carbon emission influence factor based on preset influence factor parameters and the historical urban traffic carbon emission related data comprises: determining the historical motor vehicle electromotion proportion according to the number of the electric vehicles and the number of the non-electric vehicles in the historical motor vehicle; determining the future motor vehicle motoring proportion according to the historical motor vehicle motoring proportion and the final value of the motor vehicle motoring proportion.
Specifically, the following formula can be adopted to calculate the historical motorization ratio of the motor vehicle:
wherein,motor vehicle motorization ratio, Q, representing history EV Number of electric vehicles in motor vehicles, Q, representing history FV Representing the number of non-electric vehicles in the historical automobile. Taking the calculation of a certain type of motor vehicle in a certain year in the past as an example, historical urban traffic carbon emission related data, namely the number of electric vehicles and the number of non-electric vehicles in the motor vehicle of the type in the current year, are firstly obtained, and then the number of the electric vehicles and the number of the non-electric vehicles are substituted into the formula, so that the electric proportion of the motor vehicle of the type in the current year can be obtained. Similarly, the proportion of the motorization of the motor vehicle in any other time period such as a past month can be calculated through the formula. The historical motor vehicle electromotion proportion in the city can be determined by calculating the historical electromotion proportion of all types of motor vehicles. Of course, the number of electric vehicles and the number of non-electric vehicles in the motor vehicle of the type can be directly obtained and substituted into the formula, so that the historical motor vehicle electromotion proportion in the city can be obtained.
In calculating the historical motor vehicle electromotion proportionThen, will be based onAnd substituting the preset final value of the motor vehicle electromotion proportion into a corresponding calculation model to obtain the future motor vehicle electromotion proportion. In one example, determining the future vehicle motorization ratio based on the historical vehicle motorization ratio and the final value of the vehicle motorization ratio includes: selecting an S-shaped curve model; calculating the future vehicle motorization ratio by the sigmoid curve model based on the historical vehicle motorization ratio and a final value of the vehicle motorization ratio. In the example, the proportion increase curve of the electric vehicle is simulated by an S-shaped curve, so that the future electric proportion of the motor vehicle is predicted.
There are many sigmoid curve models for selection, such as Logistic curve model (logic distribution cumulative distribution curve model), gompertz curve model (gobez curve model), weibull curve model (weber distribution cumulative distribution curve model), and the like. Taking a Logistic curve model as an example, a calculation formula of the future motor vehicle electromotion proportion is as follows:
wherein,representing the proportion of motorization of the motor vehicle in the future,represents the final value of the motorization ratio of the vehicle, n represents the number of years since the city possessed the first electric vehicle, and γ represents the slope of the curve.
For the slope γ of the curve, the motor vehicle motorization ratio can be obtained by substituting into the historyAnd the number of years n from the city having the first electric vehicle 0 Fitting is carried out to obtain that:
in the embodiment of the invention, the first type of urban traffic carbon emission influence factor is substituted into the urban traffic carbon emission prediction model, so that the future urban traffic carbon emission prediction value is obtained. When the first type of urban traffic carbon emission influence factor is the future motor vehicle electromotion proportion, the future motor vehicle electromotion proportion is substituted into the calculation factor of the urban traffic carbon emission prediction model, so that the future urban traffic carbon emission is predicted according to the future motor vehicle electromotion proportion.
Besides, a second type urban traffic carbon emission influence factor related to the first type urban traffic carbon emission influence factor can be determined, and the first type urban traffic carbon emission influence factor and the second type urban traffic carbon emission influence factor are jointly used as calculation factors to be substituted into the urban traffic carbon emission prediction model. In one example, determining a future urban traffic carbon emission prediction value by the urban traffic carbon emission prediction model based on the first type of urban traffic carbon emission impact factor comprises: determining a second type of urban traffic carbon emission influence factor, wherein the second type of urban traffic carbon emission influence factor comprises at least one of the following factors: direct emission intensity of motor vehicles, electrical emission intensity of motor vehicles, number of motor vehicles in the future; determining the urban traffic carbon emission predicted value through the urban traffic carbon emission prediction model based on the future motor vehicle electric proportion and the second type urban traffic carbon emission influence factor.
The second type of urban traffic carbon emission influence factor is also related to historical urban traffic carbon emission related data, so that the second type of urban traffic carbon emission influence factors such as direct emission intensity of motor vehicles, power consumption emission intensity of motor vehicles, and the number of future motor vehicles can be obtained by calculating the historical urban traffic carbon emission related data obtained in the historical data obtaining module 420.
In some implementations, when the second type of urban traffic carbon emission influence factor includes the number of future vehicles, historical urban traffic carbon emission related data such as the historical number of vehicles, the historical consumption capacity value of vehicles, the flatulence index, the historical average price of vehicles, the economic growth prediction rate, and the historical total domestic production value of people can be obtained in the historical data obtaining module 420, and the number of future vehicles can be calculated according to the obtained historical urban traffic carbon emission related data, so as to determine the second type of urban traffic carbon emission influence factor.
Here, when the type of the motor vehicle is a bus such as a bus, a taxi, a van, or the like, since the number of the bus is relatively stable in a city, it can be assumed that the number of such vehicles is not changed, that is, the number of future motor vehicles is equal to the number of historical motor vehicles, where the number of future motor vehicles and the number of historical motor vehicles refer to the number of the bus.
When the type of the motor vehicle is a private car, the holding capacity of the private car can change along with various influence factors such as the price of the automobile, the GDP (total production per capita) per capita and the like. Therefore, the number of the vehicles in the future needs to be predicted by combining historical data of the number of the vehicles and the like.
Exemplary, determining a future number of vehicles based on the historical number of vehicles includes: confirming a future automobile consumption capacity value; calculating a regression constant according to the historical number of the motor vehicles and the historical automobile consumption capacity value; and calculating the future number of the motor vehicles according to the regression constant and the future automobile consumption capacity value. In this example, a unary linear regression approach is taken to predict the future number of vehicles, and the historical number of vehicles refer to the number of private cars. In the process of confirming the number of the future automobiles, the step of confirming the future automobile consumption capacity value and the step of calculating the regression constant can have a sequence, can also be carried out simultaneously, and the symmetry is not limited.
Firstly, fitting according to the historical number of motor vehicles and the historical value of the consumption capacity of the motor vehicles to obtain a regression constant, wherein the following calculation formula can be adopted:
a=Q private car 0 /R 0
Wherein a represents a regression constant, Q Private car 0 Number of motor vehicles, R, representing history 0 Representing historical automobile consumption capacity values. R 0 The total value, namely R, can be produced by historical average automobile prices and historical per capita domestic production 0 = historical per-person GDP/historical average price of car.
After the regression constant a is obtained, calculating the number of future motor vehicles by a unary linear regression mode based on the regression constant a and the future automobile consumption capacity value, wherein the calculation formula is as follows:
Q private car =aR
Wherein Q Private car Representing the number of future vehicles, R representing future vehiclesA consumption capacity value.
As for the future automobile consumption capacity value R, the future automobile consumption capacity value R can be obtained by calculation according to historical urban traffic carbon emission related data such as a flatulence index, historical automobile average price, economic growth prediction rate, historical domestic production total value of everyone and the like.
Illustratively, confirming future car consumption capability values includes: determining the average price of the future automobile according to the flatulence index and the historical average price of the automobile; determining future per capita domestic production total value according to the economic growth prediction rate and the historical per capita domestic production total value; and determining the automobile consumption capacity value according to the future average price of the automobiles and the future total domestic production value of everyone. In this example, the ability to consume a car by people is reflected by the average price of the car and the total value of the domestic production by everyone. In the process of confirming the future automobile consumption capacity value, the step of determining the future average automobile price and the step of determining the future total domestic production value of everyone can have a sequence, can also be carried out simultaneously, and is not limited symmetrically.
The flatulence index, also known as the inflation rate, refers to the rate at which the general total price level rises over a period of time (usually a year). In this example, the flatulence index may be chosen as a flatulence prediction index I issued for the city government. The formula for calculating the average price of the future (after n years) of the automobile according to the flatulence prediction index I and the historical average price of the automobile is as follows:
future average price of automobile = historical average price of automobile × (1 + I) n
The economic growth prediction rate is used for predicting the economic growth rate in a certain time in the future, and an economic prediction index x issued for the city government can be selected. The formula for calculating the future (after n years) total domestic production value of the everyone according to the economic prediction index x and the historical total domestic production value of the everyone is as follows:
future people GDP = historical people GDP x (1 + x) n
After the average price of the future automobile and the total domestic production value of the future everyone are calculated, the future automobile consumption capacity value R can be further calculated, and the calculation formula is as follows:
r = mean future average GDP/mean future price of cars
In some implementations, when the motor vehicle is a non-electric vehicle, the second type of urban traffic carbon emission influence factor includes a direct emission intensity of the motor vehicle, historical urban traffic carbon emission related data such as an average travel distance of the motor vehicle, energy consumption per kilometer of the motor vehicle, and a unit energy consumption carbon emission amount of the motor vehicle may be acquired in the historical data acquisition module 420, and the direct emission intensity of the motor vehicle is calculated according to the acquired average travel distance of the motor vehicle, energy consumption per kilometer of the motor vehicle, and the unit energy consumption carbon emission amount of the motor vehicle, so as to obtain the second type of urban traffic carbon emission influence factor. Specifically, the following formula can be adopted for calculation:
wherein,representing the direct emission intensity of the motor vehicle, D i Representing the mean driving distance, FC, of the motor vehicle i Representing the energy consumption per kilometer of the vehicle, CEF represents the specific energy consumption carbon emission of the vehicle. When the average driving distance D i The annual average driving distance can be calculated, and the direct emission intensity of the annual motor vehicle can be calculated; when the average driving distance D i The monthly average driving distance or the driving distance of other time duration, and accordingly, the direct emission intensity of the motor vehicle of the monthly or other time duration can be calculated. And because the energy consumption per kilometer, the carbon emission per energy consumption and the like of different types of motor vehicles are different, the direct emission intensity of each type of motor vehicle can be respectively calculated by adopting the formula and then summarized to obtain the direct emission intensity of the urban motor vehicle.
In some implementations, when the motor vehicle is an electric vehicle, the second type of urban traffic carbon emission influence factor includes an electricity consumption emission intensity of the motor vehicle, historical urban traffic carbon emission related data such as a unit electricity consumption carbon emission variation trend of the motor vehicle, a historical unit electricity consumption carbon emission of the motor vehicle, an average driving distance of the motor vehicle, energy consumption per kilometer of the motor vehicle, and the like can be acquired in the historical data acquisition module 420, and the electricity consumption emission intensity of the motor vehicle is calculated according to the acquired unit electricity consumption carbon emission variation trend of the motor vehicle, the historical unit electricity consumption carbon emission of the motor vehicle, the average driving distance of the motor vehicle, and the energy consumption per kilometer of the motor vehicle, so as to obtain the second type of urban traffic carbon emission influence factor.
Specifically, the unit electricity consumption carbon emission of the future motor vehicle is determined according to the unit electricity consumption carbon emission change trend of the motor vehicle and the unit electricity consumption carbon emission of the historical motor vehicle. The unit carbon consumption emission amount changes with the adjustment of the energy structure, taking the adjustment of the energy structure of china as an example, the change trend of the unit carbon consumption emission amount of the motor vehicle can be set to decrease by 2.4% year by year, and then the calculation formula of the unit carbon consumption emission amount of the motor vehicle (after n years) in the future is as follows:
CEE=CEE'×(1-2.4%) n
where CEE' represents the unit electricity consumption carbon emission of the historical motor vehicle, which is released by the country or the local place, and CEE represents the unit electricity consumption carbon emission of the future motor vehicle.
Then, calculating the power consumption emission intensity of the motor vehicle according to the average driving distance of the motor vehicle, the energy consumption per kilometer of the motor vehicle and the unit power consumption carbon emission of the future motor vehicle, wherein the calculation formula is as follows:
wherein,representing the intensity of the electrical emissions of the motor vehicle, D i Representing the average driving distance, EC, of the motor vehicle i Representing the energy consumption per kilometre of the motor vehicle. When the average driving distance D i Is the annual average driving distanceCalculating the annual power consumption emission intensity of the motor vehicle; when the average driving distance D i The average driving distance per month or the driving distance of other time periods, and accordingly, the power consumption emission intensity of the motor vehicle per month or other time periods can be calculated. And because the energy consumption per kilometer, the unit power consumption carbon emission and the like of different types of motor vehicles are different, the power consumption emission intensity of each type of motor vehicle can be respectively calculated by adopting the formula and then summarized to obtain the power consumption emission intensity of the urban motor vehicle.
After the second type of urban traffic carbon emission influence factor is determined, a future urban traffic carbon emission predicted value can be calculated through an urban traffic carbon emission prediction model based on the future motor vehicle electromotion proportion and the determined second type of urban traffic carbon emission influence factor.
In one example, determining the urban traffic carbon emission prediction value by the urban traffic carbon emission prediction model based on the future motorization ratio and the second type of urban traffic carbon emission impact factor comprises: calculating the carbon emission of the electric vehicle according to the future electric vehicle motorization proportion, the electric vehicle power consumption emission intensity and the future number of the electric vehicles; calculating the carbon emission of the non-electric vehicle according to the future electric vehicle motorization proportion, the direct emission intensity of the motor vehicle and the future number of the motor vehicles; and calculating the urban traffic carbon emission predicted value according to the carbon emission of the electric vehicle and the carbon emission of the non-electric vehicle. In this example, the predicted urban traffic carbon emission values are summarized by calculating the carbon emission of future electric vehicles and the carbon emission of non-electric vehicles, respectively.
