摘　　要：由于车道被占用是指因交通事故、路边停车、占道施工等因素,导致车道或道路横断面通行能力在单位时间内降低的现象。选取沈阳某高校门前的主要干道发生的两起典型交通事故,以车道通行能力为研究对象。统计每隔30 s的车辆数,来算出1h所能通过的标准车最大辆数,并求出单向车道的可能通行能力及各方向行驶的情况进行分析说明同一横断面交通事故所占车道不同对该横断面实际通行能力影响的差异。The lane occupied is a phenomenon of reducing the traffic capacity of road or road cross section within the unit time because of traffic accident, roadside parking, construction occupying land and the other factors. Taking the lane traffic capacity of two typical traffic accidents in the main roads in the front of a university of Shenyang City as the study object, the article adds up the vehicle number every 30 s to calculate the maximum number of standard vehicles passing in 1 h, and seeks the possible traffic capacity of one-way lane and the situation of traffic every direction. The analysis shows that the different occupied lanes of traffic accident at a same cross section will have the different influences on the practical traffic capacity of this cross section.
