【摘要】：在逐日动态演化模型框架下,引入了ATIS的一致性交通预测信息,以研究其对个体出行者的路径选择行为作用以及对整体路网交通流动态演化过程的影响。按照对ATIS交通预测信息的使用与否,将路网中的所有出行者划分为两类,在此基础上,构建了一个逐日交通流演化模型,模拟路网中两类出行者的路径选择动态调整过程。对演化模型的不动点及其存在性、唯一性等理论特性进行了研究。同时,通过对模型稳定性条件的分析,证明了一致性交通预测信息增强了路网交通流演化的渐进稳定性。数值试验结果表明:出行者接收交通预测信息时受到的误差影响越小,路网交通流演化过程越容易趋于稳定。研究结果将有助于智能交通系统的优化设计。
[Abstract]:In the framework of the daily dynamic evolution model, the consistent traffic prediction information of ATIS is introduced to study the influence of ATIS on the path selection behavior of individual travelers and on the evolution process of traffic flow in the road network as a whole. According to the use of ATIS traffic forecast information, all the travelers in the road network are divided into two categories. On this basis, a daily traffic flow evolution model is constructed to simulate the dynamic path selection process of the two types of travelers in the road network. The fixed point, existence and uniqueness of the evolutionary model are studied. At the same time, through the analysis of the stability conditions of the model, it is proved that the consistent traffic forecasting information enhances the gradual stability of the road network traffic flow evolution. The numerical results show that the less error the traveler receives the traffic forecast information, the easier the evolution process of traffic flow tends to be stable. The research results will be helpful to the optimization design of intelligent transportation system.
