Abstract�� Based on the characteristics of high speed, the movement was constrained by roads, and the vehicle networking topology changed frequently, a cooperative traffic safety alarming method based on epidemic model was presented, and the transmitting delay was analyzed with Markov chain. The method was tested with NS2 network simulator. The simulation scenario contains a 2 000 meters long and 20 meters wide highway, which allows two-way movements of vehicles. The experimental results prove that the transmitting delay is consistent with the theory analysis.
Keywords�� vehicle infrastructure integration   traffic safety   epidemic model   Markov chain
