<正>研究了无控交叉口冲突点处的交通运行状况，提出了无控交叉口相冲突车流轮流占用冲突点资源的观点；从理论分析的角度提出了无控交叉口冲突点延误的计算模型。通过实例计算分析，认为无控交叉口冲突点延误主要与相冲突车流的流量有关。

This paper studies the running modes of the stream at the conflict points and advances a viewpoint that the conflicting streams use the resource of the conflict points in turn. And a calculate model is set up to deal with the delay at the conflict points in nonsignal intersection’s. Finally, an instance’s calculate result shows that the delay at conflict points of non_signal intersections is related to the volume of the conflict streams.
