论证了交通网络中所有车辆花的时间的极小值等价于网络的最大输出流.同时在考虑可变速度限制,入口匝道调节和瓶颈等几个因素的前提下,根据情况我们合理选择这三者间的组合,从而获得交通网络控制的最佳性能.通过定量分析法,我们给出了一个仿真例子,说明了此方法的实用性.目的是给交通控制中心的决策部门一个依据,何时采用三者间的协调,何时可以不需要.
It is proved that the minimum value of the time spent by all the vehicles in the traffic network is equivalent to the maximum output flow of the network.At the same time, under the premise of variable factors such as variable speed limit, inlet ramp regulation and bottleneck, The combination of the three to get the best performance of traffic network control.A quantitative analysis method, we give a simulation example shows the practicality of this method.The purpose is to traffic control center decision-making department based on what When using the coordination between the three, when can not need.
