Microcosmic model simulation of single point based on the VISSIM

通过对城市交叉口交通流微观仿真模型的分析,针对给定城市交叉口各路口的一些几何参数和交通量,运用VISSIM进行交通系统的建模和仿真,得到最佳配时方案,减少路口的交通延误,并用MATLAB软件对仿真结果做了简要分析,证明了交叉口的仿真对提高路口的服务水平有很重要的意义、增加绿信比是提高道路通行能力的有效途径、阐明了仿真的重要性。

Through the city＇s analysis of microscopic simulation model about the intersection traffic flow, with the given Ding urban intersection at road junctions in some geometric parameters and volume of traffic,using the VISSIM model to simulate the traffic system,then the result is that the best timing plan is produced,and the traffic delay is decreased.Using MATLAB software,a brief analysis of the simulation proved that intersection simulation plays an important role in improving the intersection level of service,the split＇s increase is an effective way to increase road capacity ,the simulation is very important on the traffic system.
