摘　　要：基于延时动力系统思想,提出了关于动力系统的道路交通流量的仿真新算法。针对多车道、路况可变、流量可变的复杂交通环境建立了新模型,在分析多车道封闭系统和多车道路况的基础上,本新模型可以描述前后时间段对道路交通流量的相互影响。仿真数据结果表明,新模型能够模拟交通流量变化,同时对于控制交通流量以及分析交通系统的特点是有效的。结果推广并改进了文献[2,3]中的相关结论。A new method to study road traffic flow＇s modeling was proposed based on a delay kinetic system approach. The model was established for the complex traffic environment of multi-lane, variable road conditions and variable traffic flows. Based on the analysis of multi-lane closed systems and multi-lane road conditions, the new mathematical model is able to describe the behavior for the interactions of before and after time period for the road traffic flow. The simulation results show that the new model discussed can describe the traffic flow changes, to control traffic flow and to give analysis of the transportation systems, which should have real applications in deal with multilane traffic flows in the practice. The new results improve or generalize the corresponding results given by literatures [2,3].
