Aiming at the phenomenon that the current traffic congestion detection scheme has a long cycle and low efficiency of the information transmission in the city, this paper proposes a traffic congestion detection and congestion information forwarding scheme based on Vehicular Ad-hoc NETwork (VANET) technology. Based on vehicle-to-vehicle communication mode, the scheme first determine the occurrence of traffic congestion, through the congestion similarity theory combined with the communication link quality factors, select the appropriate congestion information forwarding nodes, achieve real-time rapid dissemination of information, reduce the amount of redundant information congestion purposes. Finally, the simulation results show that the proposed scheme has significant advantages in terms of information loss rate, propagation delay and forwarding rate and effectively improve the efficiency of traffic congestion information dissemination.
