Embodiment Construction
[0047] Such as Figure 1 to Figure 5 As shown, a V2V-based collaborative urban road congestion detection method specifically includes the following steps:
[0048] 1), first detect the vehicle O position traffic congestion level LOS O ;
[0049] 2), establish a system for statistics and real-time storage of vehicle O information and storage of other vehicles O around i The neighbor table of the location information;
[0050] 3) When the traffic congestion level LOS is detected O When it is congested, vehicle O performs congestion message verification, that is, obtains the information of vehicle O in the neighbor table i Traffic Congestion Level LOS i Information and VehicleO i Location information, according to the central limit theorem and hypothesis testing based on large sub-sample, assuming H 0 :LOS=LOS o Established; when the vehicle detects that congestion occurs, and the number of vehicles i in the vehicle's neighbor table is large, the statistic is:
