基于VISSIM仿真的信号交叉口优化方法研究

传统信号交叉口配时往往只考虑车辆延误指标,存在一些不足.故此,建立了考虑延误和停车次数的信号配时优化模型,提出应用VISSIM仿真软件与信号配时相结合的信号交叉口优化方法,并将该优化方法应用于交叉口优化实例中,仿真评价结果表明:采用该方法优化交叉口效果显著,平均排队长度、平均延误指标下降明显,能够很好地从时间和空间两方面改善交叉口的性能.

Optimization Method of Signal Control Intersection based on VISSIM Simulation

The traditional intersection signal timing has some shortcomings, which only considering the vehicle delay. This paper established the signal timing optimization model not only considering the vehicle delay but also the vehicle stop times. It proposed an optimization method of signal control intersection combined with signal timing and vissim simulation, and this method was used in an example whose result showed that the average queuing length and average delay declined obviously. This method can optimize the performance of the intersection from the aspects of time and space.
