摘　　要：通过分析无控制状态下行人穿越道路时机动车的运行状态,运用排队论和流体力学理论推导出在不同流量条件下路段车辆延误模型,采用定性与定量分析相结合的方法分别讨论了路段交通流量很小、较大和很大三种情况下,行人穿越道路对路段交通流的影响,为设置行人过街设施或是否限制行人过街提供了依据。The paper analyzes the operation condition of vehicles under pedestrian cross-road without controlling, and adopts the queuing and fluid mechanics theory to derive delay model for vehicles under different flow conditions, the method combining qualitative and quantitative discussion is used to demonstrate the influence of pedestrians cross road on traffic flow in the conditions that the traffic low is very small, large and very large. The study provides a basis for the setting of pedestrian crossing facilities or whether to restrict pedestrian crossing.
