摘　　要：针对实际行驶车速的不确定性,分析了行驶车速变化对交通信号绿波协调控制方案实际效果的影响;通过确定行驶速度的正常变化区间,设定绿波协调控制平均设计车速,生成干道绿波协调控制备选方案;根据速度分布下的绿波带宽期望评价备选方案,并对方案进行优选.算例分析与仿真实验结果表明,该方法考虑了干道不同行驶方向行驶速度的变化范围与分布情况,可依据行驶速度的数据样本与概率分布,在多个备选方案中优选出一套面向行驶速度区间需求的最佳绿波协调控制方案,实现了交通信号协调控制方案风险的量化评估,提高了干道绿波协调控制方案的适应性与鲁棒性.Aiming at the uncertainty of actual running speed of vehicles, the influence of speed variation on actual results of green wave coordination control scheme for traffic signals is analyzed. Then, by determining the velocity band of normal moving vehicles and by setting the average design speed for green wave coordination control, alter- native schemes of arterial green wave coordination control are generated. Finally, on the basis of green wave bandwidth expectation, the alternative schemes are evaluated and optimized under corresponding velocity distributions. The results of example analysis and simulation show that the proposed method takes into consideration the velocity band and distribution in different arterial directions and helps choose the best green wave coordination control scheme from many alternative schemes according to sampled data and probability distribution of actual running speed. Thus, it is efficient in realizing the quantitative risk evaluation of coordination control schemes for traffic signals and improving the adaptability and robustness of arterial green wave coordination control schemes.
