Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Fig. 1 is a schematic diagram of a bus flow determination logic according to an embodiment of the present invention. As shown in fig. 1, the bus flow determination logic mainly includes:
acquiring a bus driving track generated when a bus drives on a road from bus data, wherein the bus driving track comprises a series of position points returned when the bus drives on the road, and the position points at least comprise longitude and latitude coordinates and time; the running length of one bus running track can be obtained through the sum of the distances between every two adjacent position points in the bus running track, and the running duration of the bus running track can be obtained through calculating the difference of the time in the head position point and the tail position point;

and determining the public communication of each road according to the bus running track of the bus running on each road, wherein the public communication is used for representing the running state of the bus running on each road.
In a specific implementation, if the preset electronic map is divided into two or more map grids (as shown in fig. 4b, one grid is a frame), the process of matching the bus driving track with the road in the preset electronic map includes: a bus running track is broken into a plurality of bus running track sections through a preset map grid of an electronic map, wherein one section of the bus running track falling into one map grid is a bus running track section corresponding to the map grid, and the bus running track sections are matched with road sections in the corresponding map grid, so that the bus running track sections of buses running on each road section are obtained.
The public communication of each road is determined by adopting the following two technical schemes:
the first scheme is as follows: and aggregating the bus driving track sections according to the roads to obtain the total driving length and the total driving time of the buses driven on each road, and further obtaining the bus flow of each road.
Specifically, according to the road to which the road section belongs, the bus driving track sections of the buses driving on the road section belonging to the same road are aggregated to obtain the bus driving tracks of all the buses driving on the road; determining the total driving length and the total driving time of the buses driving on each road according to the bus driving track of the buses driving on each road; and finally, obtaining the bus flow of each road according to the total driving length and the total driving time of the buses driven on each road.
Scheme II: determining the total driving length and the total driving time of buses driving on each road section in the map grid to obtain the bus flow of the road section, and then aggregating the road sections according to the roads to obtain the bus exchange on each road.
Specifically, the total driving length and the total driving time of the buses driven on each road section are determined according to the bus driving track sections of the buses driven on each road section; obtaining the bus flow of each road section according to the total driving length and the total driving time of the buses driving on each road section; and according to the roads to which the road sections belong, carrying out weighted summation on the public traffic flows of the road sections belonging to the same road to obtain the public traffic flows of the roads.
Based on the schematic diagram of the bus flow determination logic shown in fig. 1, fig. 2 is a structural diagram of a bus flow determination system provided by the embodiment of the invention. As shown in fig. 2, the system includes: a bus database 210, an electronic map database 220, and a bus flow determination device 230. Wherein:
the bus database 210 is configured to store bus data generated during a bus running process, and may include bus running tracks, bus route names, and the like.
An electronic map database 220 for storing an electronic map including at least road data including names of roads, location points of the roads, and the like.
As described above, if the preset electronic map is divided into two or more map grids, the roads in the electronic map are cut by the preset map grids to form a plurality of road segments.
And the public communication determining device 230 is configured to match the bus driving trajectory of the bus within at least one preset time period acquired from the bus database 210 with the roads in the electronic map stored in the electronic map database 220, and determine public communication of each road according to a matching result. The bus flow determined by the method is used for representing the driving state of the bus driving on each road in the time period. For example, the bus flow may be the driving speed of the bus, and the driving speed reflects the speed of the bus on the road.
The technical solution of the present application is further illustrated by the following examples.
Example one
Based on the above concept of the bus traffic determination scheme, as shown in fig. 3, it is a first flowchart of a bus traffic determination method according to an embodiment of the present invention, and an execution subject of the method is a bus traffic determination device 230 shown in fig. 2. As shown in fig. 3, the method for determining the bus flow includes the following steps:
s310, acquiring the bus running track of the bus in at least one preset time period.
The bus driving track comprises a bus, a server, a vehicle-mounted positioning device, a server, a bus driving track and a bus driving track, wherein in the driving process of the bus, the position point of the bus on the road can be obtained through the vehicle-mounted positioning device, the position point can be transmitted back to the server through a network, and the bus driving track is formed by a series of position points transmitted back to the server in the driving process of one time.
Generally, there are some noise points in the position points returned to the server, where the noise point is a position point with a large difference between the position point of the bus obtained by the positioning device and the actual position of the bus, and if the position point in the obtained bus driving track is not processed in advance to remove the noise point, the obtained bus driving track may be denoised based on the following characteristic indexes, otherwise, the method may directly enter step S320:
the speed is that the running speed of the bus cannot exceed 60KM/h under the theoretical condition, if the average speed between two adjacent position points in a bus running track exceeds 60KM/h, noise exists in the two position points, and generally, one position point generated later in the two position points can be considered as the noise and deleted;
as described above, the position points in the bus driving track include time in addition to the longitude and latitude coordinates, so that the bus driving track of the bus can be acquired according to the preset time period when the bus driving track is acquired. For example, the preset time period is 10:00-22:00, and the bus driving track of the bus driving in the time period is to be acquired, so that the acquisition of the bus driving track can be completed by judging whether the time contained in the first position point in the bus driving track falls into the preset time period. Of course, if the bus driving track from 10 to 22 is to be acquired, it needs to be determined whether a time period formed by the time included in the first position point and the time included in the last position point in the bus driving track falls into the preset time period, so as to complete the acquisition of the bus driving track. The invention is not limited in any way based on the specific rule of the bus running track required to be acquired in the preset time period, and the technical personnel in the field can specifically set the rule according to the requirement without influencing the implementation of the invention.
And S320, matching the bus running track with a road in a preset electronic map to obtain the bus running track of the bus running on the road in the time period.
S330, determining the public communication of each road according to the bus running track of the bus running on each road in the time period, wherein the bus flow is used for representing the running state of the bus running on each road in the time period.
After the bus running track of the bus running on each road in the time period is obtained, the running state of the bus running on each road can be determined. Such as the total travel length, the total travel duration, the travel speed, etc. of the bus during the time period. In a specific implementation, one or more parameters for representing the driving state of the bus driving on each road within a certain time period can be determined as the public communication of the corresponding road.
Example two
As shown in fig. 4a, a second flowchart of a bus flow determination method according to an embodiment of the present invention is shown. The difference between this embodiment and the method shown in fig. 3 is that this embodiment adopts a preferred implementation of matching the bus driving track with the road in the electronic map. As shown in fig. 4a, after step S310 of the present embodiment, the following steps are performed:

The preset electronic map in the scheme is divided into at least two map grids in advance. For example, as shown in fig. 4b, a map grid (two grids shown by dotted lines in the figure) refers to a grid with the same shape and size formed by performing mesh segmentation on an electronic map according to a preset grid size, and each grid corresponds to a certain geographic area range. For example, the geographic area coverage for each map grid may be a rectangular area of 50 meters x50 meters.
Accordingly, in the process of gridding the electronic map, the roads (shown by solid lines in fig. 4 b) in the electronic map are also divided into different map grids. A road may be divided into different map grids, where a segment of a road falling into the same map grid is a road segment corresponding to the map grid. A map grid may include road segments of multiple roads.
It should be noted here that there is also a case where one road is in one map grid, and therefore, the road segments included in the map grid in the present invention may be a complete road or a part of a road, and in any case, they are collectively referred to as the road segments corresponding to the map grid.
Since the geographic area range corresponding to each map grid is known, and the bus driving track includes a series of position points, as shown in fig. 4b, the bus driving track can be interrupted by the map grid of the electronic map to obtain a bus driving track section corresponding to each map grid, wherein one section of the bus driving track (shown by scattered points in fig. 4 b) falling into the same map grid is a bus driving track section corresponding to the map grid. Each bus driving track is divided into one or more bus driving track sections by the map grid. A plurality of bus driving track sections can also be included in one map grid.
And S420, matching the bus driving track section with the road section in the corresponding map grid to obtain the bus driving track section of the bus driving on each road section in the preset time period.
That is, the bus travel track segment in the same map grid is matched with the road segment by taking the map grid as a unit, so as to obtain the bus travel track segment of the bus traveling on each road segment in the time period.
Specifically, matching the bus travel track segment with the road segment in the corresponding map grid to obtain the bus travel track segment of the bus traveling on each road segment within the preset time period may include:
the direction of the bus driving track section is matched with the direction of the road section in the corresponding map grid, so that the bus driving track of the bus driving on each road section in the time period is obtained, wherein whether the directions are matched can be judged through whether the two parameters of the distance and the direction are matched.
Specifically, for a bus driving track section and a road section in the same map grid, based on a shape point (including longitude and latitude coordinates) of a road and a position point of a bus driving track, the bus driving track section located at the periphery of the road section is extracted, then, the distance between the road section and the bus driving track section at the periphery of the road section is obtained, the bus driving track section with the minimum distance is selected, whether the angle difference between the selected bus driving track section and the whole direction of the road section is smaller than a preset angle or not is judged, whether the length of the bus driving track section is larger than a preset length or not is judged, and if yes, the bus driving track section is determined to be the bus driving track section of a bus driving on the road section.
And S430, according to the roads to which the road sections belong, aggregating the bus running track sections of the buses running on the road sections belonging to the same road to obtain the bus running tracks of the buses running on the roads in the time period.
Specifically, after the bus driving track sections of the buses driving on the road sections are determined, the bus driving track sections of the buses driving on the road sections belonging to the same road can be aggregated, so that the bus driving tracks of the buses driving on the roads in the time period can be obtained.
After step S430, step S330 may be continued.
The method provided by the second embodiment of the present invention is based on the method shown in the first embodiment, and the map grid is used as an index unit, the obtained bus driving track is mapped to the map grid, a bus driving track segment corresponding to each map grid is obtained, then the bus driving track segment is matched with a road segment in the same map grid, a bus driving track segment on each road segment is obtained, and then the bus driving tracks of buses driving on different roads are quickly obtained.
Further, the present invention provides another preferred embodiment based on the method provided in fig. 4a, and the difference between this embodiment and the embodiment shown in fig. 4a is that step S330 may adopt the preferred technical solution shown in fig. 4c, and specifically includes:
and S440, determining the total driving length and the total driving time of the buses driven on each road according to the bus driving track of the buses driven on each road in the time period.
As shown in fig. 4b, the bus driving track is formed by a series of position points, the position points may correspondingly include longitude and latitude coordinates and time, the driving length of a bus driving track may be obtained by a sum of distances between each adjacent position point in the bus driving track, and the driving duration of a bus driving track may be obtained by differencing the time in the head and tail position points.
After the running length and the running time of each bus running track are obtained, the running length and the running time of the bus running tracks of the buses running on the same road are added respectively, so that the total running length and the total running time of the buses running on each road are obtained.
S450, obtaining the bus flow of each road according to the total driving length and the total driving time of the buses driving on each road.
For example, the ratio of the total travel length of the buses running on each road to the total travel time, i.e., the travel speed, may be used as the public traffic of the corresponding road.
The embodiment is based on the embodiment shown in fig. 4a, and further determines the total driving length and the total driving time length of the buses driving on each road through the bus driving track of the buses driving on each road; then, the bus flow of each road is obtained according to the total driving length and the total driving time of the bus driving on each road, for example, the driving speed of the bus driving on each road represents the driving speed state of the bus on the road.

Then, the bus flows of all road sections belonging to the same road are subjected to weighted summation, so that the bus flow of the corresponding road is obtained, such as the running speed of a bus running on the road.
