Section is as candidate road section), local road network is constructed according to candidate road section, and generate weighted digraph, wherein the weight in section can
To be set as the length in section.Algorithm (or other shortest path firsts such as A* etc.) is drawn using enlightening Brian Jacks, on local road
Zequin obtains the target road section sequence of the composition shortest distance to the shortest distance of terminal in net.According to target road section sequence
Return to the information that front end needs.
Specifically, by taking charge operation as an example, after driving to hold selected beginning and end, calculation road can be sent and requested to map
Server carries out path planning by map server, if high comprising high speed city in the path of planning, state's provincial highway, and Map Services
The part latitude and longitude coordinates string and vehicle-related information can be returned to four-dimensional high speed according to transport protocol predetermined by device
Charge service platform.After four-dimensional high speed charge service platform obtains coordinate string, path is carried out according to above-mentioned Path Matching Algorithm
Matching, if obtaining the trunk section in four-dimensional road network, then being calculated according to the charging standard and business principle mounted on section should
After high speed needed for path is taken, map server is returned to.Finally, map server is together with the road after pay imformation and planning
Diameter is fed back to together to be driven to hold.
In the prior art, planning path and is sent to service according to the map of local version come planning path by terminal side
Device.Since the map of server side may be the map of latest edition, and the map of terminal side is old edition map, if direct root
The case where feeding back road section information according to the planning path that terminal is sent to terminal, be then easy to appear section matching error, so as to cause
The road section information inaccuracy that terminal side receives.
In view of the above-mentioned problems, server parses longitude and latitude from the planning path that terminal is sent first in the present embodiment
Information (this is because the road section ID of same road segment may change in the map of different editions, but the longitude and latitude of same road segment
Information will not change, so as to evade because map version it is inconsistent caused by section matching error), then according to longitude and latitude
Information is spent, searches for the section for meeting preset condition in R tree, and local road network is constructed (due to preparatory in R tree according to the section found
It is loaded with the section spatial index established according to road net data, therefore, after known latitude and longitude information, R tree can be passed through
The local road network of building to carry out section matching to the planning path of terminal.The road section ID obtained at this time is the latest edition of server
The road section ID of this map matches with the planning path of terminal, so as to avoid server side according to the road section ID of mistake
To the road section information of terminal feedback error).
It should be noted that since the road section information on the map of terminal side is frequently not latest edition or it is loaded
Road section information is not comprehensive enough, and therefore, the lateral server side of terminal sends planning path, it is therefore an objective to get the rule from server side
Draw more additional informations in the corresponding road section of path.And the method in the present embodiment is applied, server is determining target road section
After ID sequence, the additional information that the ID sequence of the target road section and the target road section are included is fed back into terminal, thus
Available to arrive accurate road section information, the additional information of feedback has enriched terminal data, terminal can have been supported to mention for user
