以元胞自动机模型为基础,将连续的运动离散化,根据实际中车辆在转盘中变速与换道、进出等交通规则制定了环形多道模拟算法.此外,通过增加车辆尺寸参数,比较准确的模拟了混合车流在单/多车道转盘中的运动.对任意一个转盘,模拟算法可以模拟出转盘的交通流,并得到车辆的平均延误时间,从而判断是否实现了时转盘的最优控制.Abstract: On the basis of Cellular Automaton,by discretizing the consecutive movement of a car,we make the cor-responding simulation algorithm for cars to change speed and lane according to the actual traffic rules for cars at a traffic circle to change speed and lane.Further,by adding the size of a car as a parameter into the system,we precisely simulate the motion of mixed flow in the single/multiple lane.For any specific traffic circle,the simulation algorithm can simulate the traffic flow,and calculate the average delay time of cars in the system.On the basis of the simulation results and calculation results we can decide whether we have achieved the optimal eontrol over the system. 相似文献
