Embodiment Construction
[0039] Below, the present invention will be further described in conjunction with the accompanying drawings and specific embodiments.
[0040] like figure 1 As shown, a Beidou-based urban road network vehicle route planning method is realized by using several Beidou floating vehicles 1, data communication and storage server 2, map matching processing server 3, route planning server 4 and publishing terminal 5 connected in sequence (such as image 3 shown), the method includes the following steps:
[0041] S1. Use the floating car technology to detect the dynamic parameters of all Beidou floating cars 1 in the urban road network, including time, coordinates and direction angle data. The detected dynamic parameters are stored in the map matching processing server 3 in real time through the data communication and storage server 2 .
[0042] S2. Construct the basic model of the urban road network, and load the urban road network node set, road section set and routing set;
