Abstract: | A new car-following model is proposed by considering information from a number of preceding vehicles with intervehicle communication.A supernetwork architecture is first described,which has two layers:a traffic network and a communication network.The two networks interact with and depend on each other.The error dynamic system around the steady state of the model is theoretically analyzed and some nonjam criteria are derived.A simple control signal is added to the model to analyze the criteria of suppressing traffic jams.The corresponding numerical simulations confirm the correctness of the theoretical analysis.Compared with previous studies concerning coupled map models,the controlled model proposed in this paper is more reasonable and also more effective in the sense that it takes into account the formation of traffic congestion. |
