[ background of the invention ]
With the popularization and use of the shared bicycle in medium and large-sized cities, people can use the shared bicycle in a public transportation mode except for the conventional subway and bus. With the popularization of the shared bicycle, more and more public transport travel users can also choose to ride the shared bicycle as a connection route connecting a departure place (or a destination) and a transportation junction such as a subway station (or a bus station).
In the prior art, when a user uses an Application (App) such as an electronic map to perform travel planning, a server of a related Application may calculate travel time for the user, so as to provide reference for the user to perform travel arrangement. For example, if a user selects to take public transportation such as a bus and/or a subway, since the user taking the bus or the subway cannot be located, the server of the related application cannot acquire the travel information of the user taking the subway or the bus, and therefore the travel time of the user taking the bus and/or the subway cannot be accurately acquired. And the travel time of the user taking the public transport can be roughly calculated only according to the running distance and the running speed of the public transport or the subway.
However, in the prior art, when a user takes public transportation, transfer is usually needed, and a certain walking distance exists between transfers, and the time spent for the user to take public transportation cannot be estimated when the user takes public transportation, so that the accuracy of the time spent for public transportation travel estimated in the prior art is low.

[ detailed description ] embodiments
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
Fig. 1 is a flowchart of a processing method for public transportation travel according to an embodiment of the present invention. As shown in fig. 1, the processing method for public transportation travel in this embodiment may specifically include the following steps:
100. obtaining effective riding tracks of a shared bicycle of a plurality of users who jointly travel with the shared bicycle through public transportation in a target area;
the execution main body of the processing method for public transportation travel time in the embodiment is the processing device for public transportation travel time, and is used for acquiring the public transportation travel time accurately, so that accurate travel time prompt is provided for a user when the user carries out a public transportation navigation request according to the acquired public transportation travel time.
With the popularization of the shared bicycle, more and more users ride the shared bicycle to serve as a connection route for connecting a departure place (or a destination) and a transportation junction such as a subway station (or a bus station). In this embodiment, the riding tracks of the shared bicycle of each user are analyzed to obtain the effective riding tracks of the shared bicycle of the users who jointly travel through the public transportation and the shared bicycle, so that the travel time of the public transportation at the departure station and the destination station is estimated according to the effective riding tracks.
For example, in this embodiment, the step 100 may specifically include the following steps:
(a1) acquiring original riding tracks of a shared bicycle of all users within a preset time period in a target area;
(b1) and mining the effective riding track of the shared bicycle of the user who jointly travels with the shared bicycle through public transportation from the original riding tracks of all the users.
Since different areas, such as different cities, may include the same bus station or subway station, in order to effectively analyze the travel of public transportation, in this embodiment, one target area is taken as a research object, for example, one target area may be one city. The preset time period of the present embodiment may be one month, two months, three months or half a year of the original riding data. In a city, a part of users go to and from work and need to complete a part of travel by riding the shared bicycle, and the part of users are users who travel by combining public transportation with the shared bicycle. For example, when the user is at work, the user firstly takes a public vehicle to work by riding the sharing bicycle to a nearby bus station or subway station, then gets off the bus at the bus station or subway station nearby the company, and then selects the sharing bicycle to ride to the company. Therefore, even if the data of the public transportation cannot be collected, the travel time from the departure station to the destination station through the public transportation can be mined according to the shared bicycle track of the user. The present embodiment is implemented based on the above principle. Firstly, on the premise of not knowing which part of the original riding tracks of the users are effective and which part of the original riding tracks of the users are invalid, the original riding tracks of the shared bicycle of all the users in a preset time period in a target area can be collected firstly; and then mining the collected original riding data to obtain the effective riding track of the shared bicycle of the user who jointly travels with the shared bicycle through public transportation.
For example, the step (b1) may specifically include the following steps:
(a2) obtaining riding track pairs of all users from original riding tracks of all the users, wherein each riding track pair comprises two sections of original riding tracks, and the time interval between two successive riding of the corresponding user does not exceed the preset time length;
specifically, the riding tracks of the users who travel by the public transportation and the shared bicycle in a combined mode have a characteristic that the time interval between two consecutive riding is approximately equal to the time of use on the public transportation. Normally, the length of the bag is not too long when the bag is used on public transportation during work. For example, not more than an hour, or one and a half hours or two hours, the specific time interval length may be set according to the size of the target area, such as a city, and traffic conditions.
In this embodiment, the acquired original riding tracks are acquired according to the users, and the original riding track of each user may include original riding tracks of a plurality of time periods. Some riding tracks have no relation with riding tracks in the up-down time period, for example, a user selects a riding paragraph for one hour on the weekend, then other riding tracks do not exist in the day, and the original riding tracks do not contribute to public transportation time and can be filtered. Or the user selects to ride the sharing bicycle in the process of visiting the park on the weekend and then rides back, and according to the original riding tracks, the user can be deduced that the user does not ride public transport, and other similar original data which do not contribute to public transport can be filtered. For example, in this embodiment, the riding track pairs of each user may be preferentially obtained from the original riding tracks of all users, and each user may include one riding track pair or may include countless pairs, for example, a user who gets on or off duty daily through public transportation plus riding, and there are at least two riding track pairs each day. Each riding track pair comprises two original riding tracks, wherein the corresponding two original riding tracks have the time interval that the two consecutive riding of the user does not exceed the preset time length.
(b2) Judging whether a bus station or a subway station exists in a preset area range of a terminal point of the previous riding and a starting point of the next riding in each riding track pair; wherein the terminal point of the previous riding is different from the starting point of the next riding; if yes, executing step (c 2); otherwise, the riding track pair is directly discarded and is not used as effective data for subsequently acquiring the travel time of public transportation from the departure station to the destination station.
(c2) And taking the corresponding riding track pair as an effective riding track of the shared bicycle of the user who jointly travels through public transportation and the shared bicycle.
Then, whether each obtained riding track pair is an effective riding track is further analyzed, for example, it can be determined that a bus station or a subway station exists in a preset area range of a terminal point of the previous riding and a starting point of the next riding in each riding track pair. Because the shared bicycle occupies a small space in the driving process, the shared bicycle can reach any place where the shared bicycle can pass. Therefore, the user can try to travel to a position close enough to the destination in the process of riding the shared bicycle. For example, when a user wants to go to a bus station or a subway station, the user selects a preset area around the bus station or the subway station, such as 100 meters, to stop the bus, and then directly walks to the bus station or the subway station. In this embodiment, by using the characteristic of the shared bicycle ridden by the user, it can be determined that each riding track pair has a bus station or a subway station within a preset area range of the end point of the previous riding and the start point of the next riding, and if the riding track pair exists, the riding track pair represents an effective riding track of the shared bicycle that can be taken as the user who travels with the shared bicycle through public transportation in a combined manner. That is, the effective riding tracks of the present embodiment all appear in pairs.
101. Digging a departure station and a destination station of a user going out through public transport, a first time of entering the departure station and a second time of leaving the destination station, wherein the departure station and the destination station correspond to each effective riding track;
according to the steps, after the effective riding tracks of the shared bicycle of the user jointly traveling through the public transport and the shared bicycle are obtained, the starting station of the public transport traveling can be obtained according to the distribution condition of the bus station or the subway station near the end point of the previous section of riding track recorded in the electronic map, and the end station of the public transport traveling can be obtained according to the distribution condition of the bus station or the subway station near the starting point of the next section of riding track. Meanwhile, the starting time and the ending time of the section of riding are recorded in each section of riding track. And acquiring a first time of entering a departure station of public transportation travel and a second time of leaving a destination station of public transportation travel according to the starting time or the ending time of the riding track in each effective riding track.
For example, the step 101 may specifically include the following steps:
(a3) taking a bus station or a subway station in a preset area range around the corresponding terminal point of the previous riding in each effective riding track as a corresponding starting station of public transport trip;
(b3) taking a bus station or a subway station in a preset area range around a starting point of the corresponding next riding in each effective riding track as a corresponding destination station for public transportation trip;
from the above embodiments, it can be known that each effective riding track includes a riding track pair, and the riding track pair includes two consecutive riding tracks of one user, which may be referred to as a previous riding track and a next riding track. In this embodiment, a bus station or a subway station in a preset area range around the last riding terminal, for example, in a range of 100 meters or 50 meters, may be used as the starting station for the current public transportation trip. Similarly, the bus station or the subway station in the preset area range around the starting point of the next riding can be taken as the destination station for the public transportation trip. In this embodiment, if the starting station of the public transportation trip selects the bus station in the preset area range around the terminal point of the previous trip, the corresponding destination station of the public transportation trip also selects the bus station in the preset area range around the starting point of the next trip. Similarly, if the starting station of the public transportation trip selects the subway station in the preset area range around the terminal point of the previous trip, the corresponding destination station of the public transportation trip also selects the subway station in the preset area range around the starting point of the next trip.
(c3) Collecting the end time of the previous riding in each effective riding track;
(d3) predicting a first moment of entering a departure station according to the finish moment of the previous riding;
(e3) collecting the starting moment of the next riding in each effective riding track;
(f3) and predicting a second time of leaving the destination station according to the starting time of the next riding.
In this embodiment, when the user rides the shared bicycle to go to the bus station or the subway station, the user may select a position very close to the bus station or the subway station to stop the bicycle, in this case, the end time of the riding track may be considered to be the first time of entering the departure station of the public transportation trip, or the user may be considered to enter the departure station of the public transportation trip after about a preset minute after the end time, such as 3 minutes, 5 minutes, 8 minutes or other minutes, and at this time, the first time of entering the departure station may be considered to be the end time of the previous riding and then be delayed by a preset number of minutes.
Similarly, a user may preferably select a location near a bus station or a subway station to find a shared bicycle and quickly ride on to work when going out of the bus station or the subway station to the company. In this case, the start time of the riding track may be considered as the second time when the user leaves the destination station of the public transportation trip. Similarly, the user may also be considered to have left the destination station of the mass transit trip and walked to the shared-bicycle location approximately a preset minute before the start time, such as 3 minutes, 5 minutes, or 8 minutes or other minutes. The second time of leaving the destination station can be regarded as the starting time of the next ride and is further advanced by a preset number of minutes.
102. And acquiring the travel time of public transportation from the departure station to the destination station in the target area according to the first time and the second time in each effective riding track with the same departure station and the same destination station.
Specifically, after the departure station and the destination station of the user who travels through public transportation and the first time when the user enters the departure station and the second time when the user leaves the destination station are mined, the collected original riding track is of a certain preset time period, such as two months. At this time, if the user is on duty on a working day, a group of effective riding tracks of the user every day can be mined, and public traffic outgoing lines corresponding to the riding tracks of every day all have the same departure station and the same destination station. Then, the first time and the second time of each effective riding track with the same departure station and the same destination station can be utilized to obtain the travel time of public transportation from the departure station to the destination station in the target area.
For example, the step 102 may specifically include the following steps:
(a4) calculating the time difference between the corresponding second moment and the first moment in each effective riding track with the same departure station and the same destination station, and taking the time difference as the travel time of public transportation corresponding to the corresponding effective riding track;
(b4) and calculating the travel time of the public transportation from the starting station to the destination station in the target area according to the travel time of the public transportation corresponding to each effective riding track with the same starting station and the same destination station.
Specifically, for each effective riding track with the same departure station and the same destination station, the time difference between the second time and the first time corresponding to each corresponding effective riding track is calculated, and the time difference is used as the travel time of the public transport corresponding to the effective riding track. However, the time for traveling by public transportation may be inaccurate, and in this embodiment, the time for traveling by public transportation from the departure station to the destination station in the target area may be comprehensively calculated according to the time for traveling by public transportation corresponding to each effective riding track having the same departure station and the same destination station. For example, in the most direct mode, the travel times of public transportation corresponding to all the effective riding tracks having the same departure station and the same destination station may be averaged to be taken as the travel time of public transportation from the departure station to the destination station in the target area. Or other mathematical methods may also be used, when the travel time of the public transportation from the departure station to the destination station in the target area is calculated according to the travel time of the public transportation corresponding to each effective riding track having the same departure station and the same destination station, which is not described in detail herein for example.
Further optionally, after the step (a4) and before the step (b4), the following steps may be further included:
(a5) when the public transportation corresponding to each effective riding track with the same departure station and the same destination station is used for traveling, classifying the public transportation according to the principle that the time difference is not greater than a preset time threshold;
(b5) judging whether the public transportation corresponding to each effective riding track with the same departure station and the same destination station is classified into one type or two types when going out; if the destination station is the same as the departure station, the determined departure station and the determined destination station are correct, and the time for the public transportation from the departure station to the destination station in the target area can be directly obtained according to the step 102; otherwise, if the two types are adopted, the starting station and the destination station of one type are selected improperly, for example, the starting station and the destination station are set as bus stations by mistake when the train is taken for traveling; or the departure station and the destination station are set as subway stations by mistake at the moment when the bus is taken originally. At this point, step (c5) may be further performed;
(c5) judging whether the current departure station and the current destination station are bus stations or subway stations; if the bus stop is the bus stop, executing the step (d 5); otherwise, if the station is a subway station, executing the step (f 5);
(d5) updating a corresponding departure station with short travel time of public transportation into a subway station in a preset area range around the terminal point of the previous riding, and updating a destination station into a subway station in a preset area range around the riding point of the next riding;
(f5) and updating the corresponding departure station of the short travel time class of the public transport into a bus station in a preset area range around the terminal point of the previous riding, and updating the destination station into a bus station in a preset area range around the riding point of the next riding.
In practical applications, the time difference of public transportation travel during the process of getting on and off duty each day is not too much, for example, the user takes from the subway station a to the subway station B each day, and the time difference of travel generally does not exceed a preset time threshold, such as 10 minutes, or 8 minutes, or other minutes. Or the user rides from bus station C to bus station D each day, the time difference for traveling generally does not exceed a preset time threshold, such as 20 minutes, or 15 minutes, or other minutes. If there are bus stations and subway stations near the end point of the previous riding and there are bus stations and subway stations near the start point of the next riding in the effective riding track of the user, and the foregoing determining the departure station and the destination station of the public transportation trip can be performed by preferably selecting the subway stations or the bus stations. However, in the actual situation process, the difference between the subway trip and the bus trip is large, for example, the difference is at least half an hour, especially, the difference is large when the distance is long, and the difference is much larger than the preset time threshold, so that the time of different transportation means can be distinguished. In this embodiment, the departure station and the destination station of the public transportation trip determined in the foregoing may be also checked and corrected in steps (a5) - (f 5).
Specifically, when the public transportation corresponding to each effective riding track having the same departure station and the same destination station is used for traveling, the classification may be performed according to a principle that the time difference is not greater than the preset time threshold. That is, the distance between the departure station and the destination station is classified by the trip through the bus and the trip through the subway, respectively. If the time difference between the public transportation travel time corresponding to all the effective riding tracks with the same departure station and the same destination station is not larger than the preset time threshold, only one type can be obtained at the moment, and the departure station and the destination station of the public transportation travel determined before can be considered to be correct. If the two types of the start station and the destination station can be classified according to the mode, at this time, it can be stated that the selection of the start station and the destination station of one type is improper, for example, the start station and the destination station are set as bus stations by mistake when the train is originally taken for traveling; or the departure station and the destination station are set as subway stations by mistake at the moment when the bus is taken originally.
At this time, whether the current departure station and the current destination station are bus stations or subway stations can be determined; if the train is a bus station, updating a corresponding departure station with short travel time of public transport into a subway station in a preset area range around the terminal point of the previous riding, and updating a destination station into a subway station in a preset area range around the riding point of the next riding; if the bus station is a subway station, the corresponding departure station of the travel duration of the public transport can be updated to the bus station in the preset area range around the terminal point of the previous riding, and the destination station is updated to the bus station in the preset area range around the riding point of the next riding.
By means of the method, the time for traveling of public transportation from the departure station to the destination station can be obtained very accurately, and therefore when a subsequent user requests public transportation navigation, more accurate time data for traveling of public transportation can be provided for the user, and traveling planning of the user is facilitated.
According to the processing method for public transport travel, the effective riding track of the shared bicycle of a plurality of users who travel through public transport and the shared bicycle in the target area is obtained; digging a departure station and a destination station of a user going out through public transport, a first time of entering the departure station and a second time of leaving the destination station, wherein the departure station and the destination station correspond to each effective riding track; and acquiring the travel time of public transportation from the departure station to the destination station in the target area according to the first time and the second time in each effective riding track with the same departure station and the same destination station. According to the technical scheme, the calculation of the public transportation from the departure station to the destination station for the trip is realized based on the effective riding track of the shared bicycle of the user who jointly trips through the public transportation and the shared bicycle, and the data of the effective riding track is very accurate, so that the trip time of the public transportation from the departure station to the destination station can be accurately acquired. Based on the above, by adopting the technical scheme of the embodiment, the accuracy of the obtained public transportation from the departure station to the destination station in the trip process can be effectively improved, so that guidance can be more accurately provided for the user requesting navigation in the trip of the public transportation.
