摘要
针对现实中桥梁形成的交通流瓶颈,建立了一个基于元胞自动机交通流桥梁瓶颈模型.在周期性边界条件下,将系统的状态分成六“相”,利用平均场理论和决定性NS模型的结果,得到每条车道上的密度关系.分析的理论值与计算机数值模拟结果符合得很好.
A cellular automaton model for the bottleneck in high speed traffic caused by a bridge is proposed. It takes the initial density apart into six regions. Based on the mean field theory and the results of definitive NS model, the relations of car density of every line are given. The simulation results show that the theoretical model is correct.
