摘　　要：对交通流进行准确模拟和预测分析，实现交通路网评估，可治理交通拥堵。提出一种基于TRANSIMS的交通流模拟和分析模型，构建交通路网拥堵评估模型，根据车辆的RFID标签信息进行位置信息编码，采用最大Lyapunove指数预测算法进行交通流预测，实现路网节点负载容量的准确估计分析。在TRANSIMS场景中进行试验分析，试验结果表明，该模型适用于大规模的交通流模拟和预测评估，获得了较高的道路负载吞吐效益和速度效益。In order to perform the accurate simulation and prediction analysis of the traffic flow,evaluate the traffic net?work,and govern the traffic jams,a traffic flow simulation and analysis model based on TRANSIMS is proposed. The jam assess?ment model of the traffic network was constructed. The position information is coded according to the RFID tag information ofthe vehicle. The maximum Lyapunove exponent prediction algorithm is used to predict the traffic flow to analyze the accurate esti?mation of the load capacity of the traffic network nodes. The model was performed with experimental analysis in TRANSIMS scene. The experimental results show that the model is suitable for the large?scale traffic flow simulation and prediction evalua?tion,and has acquired the high road throughput efficiency and speed benefit.
