城市平面交叉路口微观仿真软件设计

A traffic micro-simulation software of urban at-grade intersection

为再现城市平面交叉路口的交通流,建立一种基于细胞方法的交通仿真模型,提出根据优先级进行加速和减速操作的改进模型,实现城市平面十字交叉路口的微观仿真.实验证明,微观仿真能较好地再现城市平面交叉路口的交通状况.

A major method of reappearance of traffic flow is introduced, a traffic micro - simulation software of urban at - grade intersection. Based on the method of cell traffic simulation model, we provide according to proposed priorities to operate the acceleration and deceleration for improving the model and realize the micro - simulation of urban at - grade crossroad. The experiment results show that the model can reproduce the traffic situation of urban at - grade crossing.
