种降低车辆延误和交通排放的协调信号配时优化方法，适用于有(无)左转短车道的干线交叉口群。基于协调信号对干线车流的影响分析，考虑短车道空间优化构建了干线交叉口群时空资源配置优化模型，针对短车道空间确定构建了干线交叉口群信号配时优化模型。为评价干线交叉口群的运行效率和环境状况，提出了三种具体形式的性能指标，并改进了车道组车均延误估计方法和红绿灯期间排放因子标定方法。然后，针对各种情况给出了上述模型和方法的技术应用流程。借助交通仿真软件VISSIM和编程软件MATLAB，使用算例说明了技术应用流程。结果表明，面向干线交叉口群，新方法能体化配置时空资源，实现车辆延误和交通排放的最小化，可广泛应用于信号配时设计与优化。 A coordinate signal timing dial optimization method capable of lowering vehicle delay and traffic emission is applicable to main line intersection groups with (without) left-handed rotation short lanes. On the basis of impact analysis of coordinate signals on the main line traffic flow, short-lane space optimization is considered, and a main line intersection group space-time resource allocation optimization model is constructed, and the main line intersection group signal timing dial optimization model is constructed for determining the short-lane space. In order to evaluate the operating efficiency and the environmental conditions of main line intersection groups, three performance indexes of the specifi
