The invention provides a signal control intersection waiting area combination design method which comprises the following steps: setting a straight going or left turning waiting area based on an NEMA signal control theory, and analyzing the influence of the waiting area setting on a signal period and effective green light time; listing all to-be-ranked area setting and phase sequence combination schemes, and designing a combination scheme of the to-be-ranked areas and signal phase sequence control; determining an alternative waiting area setting scheme according to the space size and the traffic flow condition, and obtaining all feasible waiting areas and phase sequence combinations; and finally, performing experimental simulation comparison and optimal selection to obtain an optimal waiting area combination scheme of the signal control intersection. According to the method, a theoretical basis can be efficiently and economically provided for the arrangement of the waiting areas of the signal control intersection, the combination and length of the waiting areas can be designed more reasonably, and the passing efficiency of the signal intersection is improved.
本发明提供一种信号控制交叉口待行区组合设计方法,包括如下步骤:基于NEMA信号控制理论,进行直行或左转待行区设置,分析待行区设置对信号周期、有效绿灯时间的影响;将全部待行区设置与相序组合方案列出,设计出待行区与信号相位相序控制的组合方案;根据空间尺寸、交通流量条件确定备选的待行区设置方案,得到所有可行的待行区与相位相序组合;最后进行实验仿真对比并进行选优,得到信控交叉口最优待行区组合方案。本发明可高效经济的为信号控制交叉口的待行区设置提供理论依据,可更加合理的设计待行区的组合以及长度,增加信号交叉口的通行效率。
