< method examples >

< example one >

In the present embodiment, a traffic control method is provided. The method may be implemented by an electronic device for traffic control of a target intersection. In one example, the electronic device may be the server 1100 shown in fig. 2a, or the terminal device 1200 shown in fig. 2 b.

As shown in fig. 3, the traffic control method of the present embodiment may include the following steps S3100 to S3400:

and step S3100, acquiring actual weather data of the target road acquired by at least two weather data acquisition devices.

The target road in this embodiment may be a road selected in advance according to an application scenario or a specific requirement.

The weather data collecting device in this embodiment may be a weather sensor disposed on the target road, a video data collecting system disposed on the target road, or a weather server. The weather server may be a device that provides a weather query service via the internet.

The actual weather data may be an actual value of a target index that reflects a weather condition, which is acquired from the weather data collection device.

The target indicator may include at least one of: temperature, humidity, amount of water on the road surface, amount of snow on the road surface, amount of rainfall in a set period of time, visibility, amount of snow in a set period of time. The set time period may be set in advance according to an application scenario or a specific requirement, and may be 1 hour, for example.

Specifically, the weather sensor disposed on the target road may collect an actual value of at least one target index of the target road as actual weather data. The weather sensor arranged on the target road may upload actual weather data of the target road collected by the weather sensor to the electronic device implementing the embodiment according to a preset first frequency. The electronic device executing the embodiment may also send a first acquisition request to a weather sensor disposed on the target road, where the weather sensor responds to the first acquisition request and uploads the collected actual weather data to the electronic device for the electronic device to acquire.

The video data acquisition system arranged on the target road can acquire a live-action video or a live-action image of the target road, and analyze at least one target index of the target road according to the live-action video or the live-action image to obtain an actual value corresponding to the target index, and the actual value is used as actual weather data. The video data acquisition system may upload actual weather data of the target road obtained by the video data acquisition system to the electronic device implementing the embodiment according to the preset second frequency. The electronic device executing the embodiment may also send a second acquisition request to a video data acquisition system arranged on the target road, and the video data acquisition system responds to the second acquisition request and uploads the obtained actual weather data to the electronic device for the electronic device to acquire.

For the weather server, the actual value of at least one target index of the target road can be determined based on the position of the target road and according to data in at least one meteorological system such as meteorological radar, ground observation, high-altitude detection, meteorological satellite, ocean observation and the like, and the actual value is used as actual weather data. The electronic device executing the embodiment may send a third obtaining request to a weather server, where the third request includes information indicating a location of a target road, and the weather server sends, in response to the third obtaining request, actual weather data of the location of the target road to the electronic device, so that the electronic device can obtain the actual weather data.

For actual weather data collected by different weather data collecting devices, corresponding target indexes can be the same or different. For example, the actual weather data collected by the weather sensor disposed on the target road may include an actual value of temperature, an actual value of humidity, an actual value of amount of water accumulated on the road surface, and an actual value of amount of snow accumulated on the road surface; the actual weather data collected by the video data collection system arranged on the target road can comprise an actual value of the amount of the water on the road surface, an actual value of the rainfall in a set time period, an actual value of the visibility and an actual value of the snowfall in a set time period; the actual weather data collected by the weather server can comprise an actual value of temperature, an actual value of humidity, an actual value of rainfall in a set time period, an actual value of visibility and an actual value of snowfall in a set time period;

step S3200, processing the actual weather data of the target road collected by the at least two weather data collection devices to obtain processed weather data of the target road.

The processed weather data in the present embodiment may be a processed value of the target index.

In an embodiment of the present disclosure, the manner of processing the actual weather data obtained in step S3100 may include: acquiring a mapping function between actual weather data and processed weather data; and obtaining a processed value of the target index according to the actual value of the target index and the mapping function.

The mapping function between the actual weather data and the processed weather data in this embodiment may include a mapping function corresponding to each target index; and for each target index, obtaining a corresponding processed value according to the corresponding actual value and the corresponding mapping function.

Further, the training mode of the mapping function for any target index may include: constructing a training sample corresponding to the target index, wherein the training sample can comprise an actual value of the target index and a processed value of the target index corresponding to each type of weather data acquisition equipment; and training to obtain a mapping function according to at least one actual value of the target index corresponding to the training sample and the processed value of the target index corresponding to the training sample.

Still further, based on at least one actual value of the target index corresponding to the training sample and the processed value of the target index corresponding to the training sample, the mapping function may be obtained by various fitting means, for example, the mapping function may be obtained by using an arbitrary multiple linear regression model, which is not limited herein.

In one example, the multiple linear regression model may be a simple polynomial function reflecting the mapping function, wherein coefficients of respective orders of the polynomial function are unknown, and the coefficients of the respective orders of the polynomial function may be determined by substituting at least one actual value of the target index corresponding to the training sample and the processed value of the target index corresponding to the training sample into the polynomial function, thereby obtaining the mapping function.

In another example, various regression models, such as an addition model, may be used to perform multiple rounds of training with at least one actual value of the target indicator corresponding to the training sample and the processed value of the target indicator corresponding to the training sample as accurate samples, each round learns the residual after the last round of fitting, and the residual is controlled to a very low value by iterating T rounds, so that the resulting mapping function has very high accuracy. The addition model is, for example, LightGBM, GBDT, XGBoost, etc., and is not limited herein.

The mapping function between the actual weather data and the processed weather data in this embodiment may also be a mapping function. Then, a processed value of each target index may be obtained based on the actual value of each target index and the mapping function. The training mode of the mapping function may refer to the foregoing embodiments, and is not described herein again.

In another embodiment of the present disclosure, the manner of processing the actual weather data obtained in step S3100 may further include: traversing all the target indexes, acquiring the weight of each weather data acquisition device corresponding to the currently traversed target index, and weighting and averaging the actual values of the currently traversed target index according to the weight of each weather data acquisition device corresponding to the currently traversed target index to serve as the processed value of the currently traversed target index.

In this embodiment, since the corresponding target indexes may be different in the actual weather data collected by different weather data collection devices, before the actual weather data is processed, the actual values of all the target indexes corresponding to each type of weather data collection device may be supplemented according to the set value. The setting value may be a value set in advance according to an application scenario or a specific requirement. For example, the set value may be 0.

Specifically, the actual value of the target index missing in the actual weather data collected by each weather data collection device may be determined, and the set value may be used as the actual value of the target index missing in each weather data collection device.

For example, in the case where the target index includes temperature, humidity, amount of road surface water, amount of road surface snow, amount of rainfall in a set period, visibility, and amount of snow in a set period, and the actual weather data collected by the weather sensor includes an actual value of temperature, an actual value of humidity, an actual value of amount of road surface water, and an actual value of amount of snow in a set period, it may be determined that the actual value of the target index missing by the weather sensor includes an actual value of visibility, an actual value of amount of rainfall in a set period, and an actual value of amount of snow in a set period, and thus, it may be determined that the set value is taken as an actual value of visibility in the actual weather data collected by the weather sensor, an actual value of amount of rainfall in a set period, and an actual value of amount of snow in a set period.

And step S3300, determining a target traffic control scheme of the target road according to the processed weather data.

In one embodiment of the present disclosure, determining the target traffic control scheme for the target road according to the processed weather data may include steps S3310 to S3330 as follows:

step S3310, at least one preset value interval corresponding to the target index is obtained.

Specifically, the preset value interval corresponding to each target index may be set in advance according to an application scenario or a specific requirement.

For example, in the case that the target index is the rainfall amount in the set period, the corresponding preset value interval may include less than 10mm, greater than or equal to 10mm and less than 15mm, greater than or equal to 15mm and less than 30mm, greater than or equal to 30mm and less than 50mm, and greater than or equal to 50 m.

For another example, when the target indicator is visibility, the corresponding preset value interval may include 100m or less, 150m or more and 150m or less, 200m or less and 200m or more, 500m or less and 500m or more.

And step S3320, determining the actual weather event corresponding to the target road according to the processed value of the target index and the preset value interval.

In this embodiment, determining the actual weather event corresponding to the target road according to the processed value of the target index and the preset value interval may include: for each target index, determining a preset value interval to which the processed value belongs as an actual value interval; and determining the actual weather event corresponding to the target road according to the actual numerical value interval of each target index.

Specifically, a plurality of weather events and a preset value interval of the target index corresponding to each weather event may be preset. And determining the weather event matched with the actual value interval of each target index as the actual weather event corresponding to the target road by matching the actual value interval of each target index with the preset value interval of the target index corresponding to each weather event.

For example, in the case where the actual numerical interval of the amount of rainfall is greater than or equal to 10mm and less than 15mm and the actual numerical interval of the visibility is greater than 200m and less than or equal to 500m within a set period of time, it may be determined that the current weather event is moderate rain.

For another example, in the case where the actual numerical interval of the rainfall is greater than or equal to 15mm and less than 30mm and the actual numerical interval of the visibility is greater than 150m and less than or equal to 200m within the set period of time, it may be determined that the current weather event is heavy rain.

For another example, in the case where the actual numerical interval of the rainfall is greater than or equal to 30mm and less than 50mm and the actual numerical interval of the visibility is greater than 100m and less than or equal to 150m within the set period of time, it may be determined that the current weather event is a heavy rain.

For another example, in the case where the actual numerical interval of the amount of rainfall is greater than or equal to 50m and the actual numerical interval of the visibility is less than or equal to 100m within a set period of time, it may be determined that the current weather event is a heavy rainstorm.

And step S3330, determining a target traffic control scheme according to the actual weather event.

In one embodiment of the present disclosure, determining a target traffic control scheme based on an actual weather event may include: acquiring a comparison table reflecting the corresponding relation between the weather event and the traffic control scheme; and searching the comparison table, and determining a traffic control scheme corresponding to the actual weather event as a target traffic control scheme.

In this embodiment, the traffic control scheme corresponding to each weather event may be set in advance according to an application scenario or a specific requirement, and the comparison table may be generated according to a correspondence between the weather event and the traffic control scheme.

For example, where the actual weather event is a moderate rain, it may be determined that the corresponding target traffic control scheme may include at least one of: (1) the speed limit is 100km/h, (2) the fog lamp is turned on (the brightness is 50 percent, and the fog lamp flickers for 30 times per second), (3) the information board prompts that rain exists in the front and cautious driving is required, and (4) the navigation prompts that rain exists and the speed limit is cautious driving. Correspondingly, under the condition that the display screen is a speed limit screen, the target display content can be 'speed limit 100 km/h'; under the condition that the display screen is an information board, the target display content can be 'rain in front and please drive carefully'

For another example, where the actual weather event is heavy rain, it may be determined that the corresponding target traffic control scheme may include at least one of: (1) the speed limit is 80km/h, (2) the fog lamp is turned on (the brightness is 70 percent, and the flashing is carried out for 60 times per second), (3) the information board prompts heavy rain ahead and slows down and (4) the navigation prompts heavy rain, and the route and the trip are reasonably planned. Correspondingly, under the condition that the display screen is a speed limit screen, the target display content can be 'speed limit 80 km/h'; in the case of a billboard display, the target display may be "heavy rain ahead, slow down.

As another example, where the actual weather event is a heavy rain, it may be determined that the corresponding target traffic control scheme may include at least one of: (1) the method comprises the following steps of (1) reserving to pass, (2) limiting the speed to 60km/h, (3) turning on a fog lamp (brightness 100%, distance warning), (4) prompting rainstorm in front and slow running by an information board, and (5) prompting rainstorm by navigation and recommending to bypass. Correspondingly, under the condition that the display screen is a speed limit screen, the target display content can be speed limit 60 km/h; in the case where the display screen is a message board, the target display content may be "rainstorm ahead, slow travel".

As another example, where the actual weather event is a heavy storm, it may be determined that the corresponding target traffic control scheme may include at least one of: (1) the speed limit is 40km/h, (2) the fog lamp is turned on (the brightness is 100 percent, and the flashing is carried out for 120 times per second), (3) the information board prompts a driver to drive nearby in a very big rainstorm ahead, and (4) the target road is shielded by navigation and directly detoured. Correspondingly, under the condition that the display screen is a speed limit screen, the target display content can be 'speed limit 40 km/h'; in the case of a billboard display, the target display may be "drive near with heavy rain ahead".

And step S3400, performing traffic control on the target road according to the target traffic control scheme.

Specifically, the traffic control system may be linked with a traffic control facility in the target road to realize traffic control on the target road. The traffic control facility may include a display screen disposed on the target road, a traffic light disposed on the target road, and a navigation server.

In this embodiment, the traffic control may specifically be performed for the vehicles on the target road. The vehicles within the target area may include automobiles, unmanned vehicles, logistics vehicles, electric vehicles, motorcycles, and the like.

In one embodiment of the present disclosure, traffic-controlling the target road according to the target traffic control scheme may include: generating target display content according to the target traffic control scheme; and providing the target display content to a display screen arranged on the target road so as to display the target display content on the display screen.

The display screen in this embodiment may be a speed limit screen for displaying speed limit information, or an information board for displaying traffic information.
