The invention provides an urban road traffic state detecting method based on a vehicle ad-hoc network. A vehicle with a wireless communication device and a GPS is selected as a traffic state 'probe' called as the probe vehicle hereinafter, communication between the probe vehicle and an RSU is achieved through the vehicle ad-hoc network, the RSU works out the time duration that the probe vehicle passes a tested road section according to the received state information and evaluates the traffic condition of the tested road according to the time duration the probe vehicle passes the tested road section. A self-adaptation window T algorithm is provided to adapt to constantly-changing traffic scenes of vehicle flow and to calculate the average passing time of all probe vehicles in a period of time. Finally, a simulation model is established for observation data of a real traffic scene, and the effectiveness of the simulation model is verified through a network simulator NS-2.
