摘　　要：对不同流量条件下交叉口的交通冲突次数进行了理论计算、仿真和实地观测验证,提出了无控制交叉口设置机动车信号灯的理论分析方法.依据该理论,并采用实际交通观测中确定的交叉口临界交通冲突次数,给出了无控制交叉口设置机动车交通信号灯交通流量临界曲线,为合理设置交通信号灯提供了理论依据.From the viewpoint of traffic safety and based on the analysis of traffic confilict, this paper advances the warrant theory for the signal installation at uncontrolled intersections. The times of traffic conflicts under certain traffic volumes are theoretically calculated and practically simulated. According to the theoretical analysis, we give a vehicular traffic signal warrant for uncontrolled intersections which can be widely used in practice to guide the installation of traffic signals.
