基于排队消散时间的干线协调信号控制研究

Research on coordinated signal control of trunk lines based on considering queue dissipation time

通过引入新的信号周期计算方法改进传统信号周期权重方案,计算得到新的信号周期。并建立一个排队消散模型,改进各交叉口的相位差。通过最大绿波带模型求解,根据模型结果代入VISSIM仿真分析结果。最终结果表明改进的信号周期计算方法与排队消散模型比传统方法有更好的控制效果,干线方向车辆停车延误降低了67.3%,平均延误降低了64.6%。

By introducing a new signal period calculation method the traditional signal cycle weighting scheme is improved,the new signal period is calculated.And propose an improved queue dissipation model to improve the phase difference between each intersection.Solve through the maximum green wave band model and substitute the model results from the VISSIM simulation analysis results.The final results indicate that the improved signal cycles calculation method and queue dissipation model have better control effects than traditional methods,with a 67.3%reduction in vehicle parking delay in the main line direction and an average delay reduction of 64.6%.
