摘　　要：基于解析的交叉口信号配时方法,往往会因为基础数据的误差,造成最终计算所得方案不是所需的最优方案,而依据交叉口进口车道数、饱和流率、流量、流向及周期间的关系建立模型,通过调整模型参数获得多种不同配时方案,并在仿真环境下运行各个方案,输出对应方案的运行指标,通过综合评价方法来确定最优方案不失为一种有效的信号配时方法。将此方法应用于实际信号配时,并与Webster法所得方案进行对比,结果表明,该方法所得方案更符合实际交通需求。Traffic signal design based on analytical method some times can＇t get optimization solution due to inaccuracy foundation data. To create a model according to relation of entrance road number, rate of saturation, flow , flow direction and circle, adjust the model parameters so can get multi--solutions. Use traffic simulation software to operate the solutions and output the targets. Estimated the targets by systems analysis method must be gain the optimization solution. Design a traffic signal for actual intersection by analytical method and simulation method separately, the result show the simulation method fit the intersection perfectly.
