As shown in fig. 2, a basic flow of a traffic speed determining method provided in an embodiment of the present application includes:

s201, obtaining track point information of a plurality of user sides.

In specific implementation, a software platform (such as a positioning software platform or a taxi-taking software platform) can acquire track point information of track points of a plurality of user terminals in real time. When the trace point information of a plurality of user sides is obtained, the trace point information belonging to the same user side can be determined according to the user side identification carried in the trace point information. Here, the trace point information of the user terminal may include one or more of the following information: the method comprises the steps of acquiring time of track points, longitude coordinates of the track points, latitude coordinates of the track points, a target road section where the positions of the track points are located, the distance from the positions of the track points to the starting point of the target road section, and the distance from the positions of the track points to the end point of the target road section.

And S202, determining the speed of the plurality of user sides passing through the target road section respectively based on the track point information.

In specific implementation, after the passing speed determination platform obtains the trace point information of the multiple clients, the passing speed determination platform may determine the speed at which the multiple clients pass through the target road segment respectively based on the trace point information of the multiple clients. For example, the corresponding speed between adjacent track points can be calculated according to the track point information for each user terminal, and then the speed of the user terminal passing through the target road segment can be determined according to the corresponding speed between the adjacent track points. Here, according to the difference of the position relationship between the trajectory point of the user end and the target road section, there may be different calculation manners for determining the speed of the user end passing through the target road section. Furthermore, when determining the speed of the plurality of user terminals respectively passing through the target road section, the position relationship between the track point of the user terminal and the target road section can be determined for each user terminal according to the track point information of the user terminal, and then the speed of the user terminal passing through the target road section is calculated according to the position relationship between the track point of the user terminal and the target road section and the track point information of the user terminal.

Here, the position relationship between the trajectory point of the user end and the target road segment is shown in fig. 3, and may include any one of the following relationships: the user side has at least two track points positioned in the target road section; a track point at the user end is positioned in the target road section; the user side does not have track points and is located in the target road section. The user side has at least two track points positioned in the target road section, which indicates that the user side has a plurality of track points positioned in the target road section when the user side passes through the target road section; the user side has one track point positioned in the target road section, which indicates that only one track point is positioned in the target road section when the user side passes through the target road section; the fact that no track point is located in the target road section indicates that no track point is located in the target road section when the user side passes through the target road section.

S203, determining the passing speed of the target road section according to the speed of the plurality of user terminals passing through the target road section respectively.

Here, the passing speed determination platform may determine the final passing speed of the target road section according to the speed at which the plurality of user terminals respectively pass through the target road section after determining the speed at which the plurality of user terminals respectively pass through the target road section based on the track point information of the plurality of user terminals. When the final passing speed of the target road section is determined according to the speed of the plurality of user terminals passing through the target road section, the passing speed of the target road section can be determined according to the speed of the plurality of user terminals passing through the target road section and the passing time of the plurality of user terminals passing through the target road section. For example, for each user side, the passing time of the user side through the target road section can be determined according to the acquisition time of the track point of the user side, and then the final passing speed of the target road section is determined according to the passing time of each user side through the target road section and the passing speed of each user side through the road section. It should be noted that, here, the passing time of the user end through the target road section may be understood as the corresponding time when the user end passes through the target road section, and in a specific implementation, the average time or the middle time when the user end passes through the target road section may be used as the passing time of the user end through the target road section.

Here, after determining the speed of the plurality of clients passing through the target road segment, the software platform may respectively determine corresponding weight values for the speed of the plurality of clients passing through the target road segment according to the transit time of the plurality of clients passing through the target road segment. The passing time of the user end through the target road section can be the corresponding time when the user end passes through the target road section. When the weighted values are respectively set for the speeds of the plurality of user terminals passing through the target road section according to the passing time of the plurality of user terminals respectively passing through the target road section, the time difference value between the passing time of the user terminals passing through the target road section and the current time can be firstly determined, and then the weighted values are respectively set for the speeds of the plurality of user terminals passing through the target road section according to the determined time difference value. Here, the time difference and the speed of the user terminal passing through the target road section may have a negative correlation, and the larger the time difference is, the smaller the weight value is set for the speed of the user terminal passing through the target road section. Therefore, the closer the passing time of the user end passing through the target road section is to the current time, the larger the weight value set for the speed of the user end passing through the target road section is.

And determining the speed of the plurality of clients respectively passing through the target road section according to the track point information counted within the preset time. When weight values are set for the speed of a plurality of clients passing through the target road section, the weight value of the speed of each client passing through the target road section can be obtained according to the weight time attenuation function designed as follows:

wherein K is the number of clients, j is the jth client, d_jIs the time difference between the transit time of the jth user end and the current time, w_jThe sum of the weighted values of the speeds of the jth client passing through the target road section within the preset time is 1.

When the entering time of the user side entering the target road section and the leaving time of the user side leaving the target road section are determined, the track point located in the target road section in the track points of the user side can be determined for each user side, and then the average acquisition time of the determined track points or the acquisition time of the middle track point in the determined track points is used as the passing time of the user side passing the target road section. The intermediate track point can be understood as a track point whose position is located in the middle of the determined track points.

S602, determining the passing speed of the target road section according to the speed of the plurality of user terminals passing through the target road section and the weight value of the speed of each user terminal passing through the target road section.

In specific implementation, after the software platform sets the weight values for the speeds of the plurality of user terminals passing through the target road segment, the software platform may calculate the final passing speed of the target road segment according to the speeds of the plurality of user terminals passing through the target road segment and the weight values of the speeds of each user terminal passing through the target road segment. When determining the passing speed of the target road section, the passing speed spd of the target road section can be obtained according to the following formula:

wherein spd is the passing speed of the target road section, K is the number of the user terminals, and spd_jSpeed, w, of the jth user terminal passing through the target road section_jAnd the weight value of the speed of the jth user side passing through the target road section.

The speed of the plurality of clients passing through the target road section is combined into the final passing speed of the target road section by setting the weight values for the speed of the plurality of clients passing through the target road section, so that the more accurate passing speed of the target road section can be obtained.
