摘　　要：针对城市道路交叉口因多车道相交,人车混行,安全设施设置不足,致行人过街困难,违章频发的问题,选取具有典型特征的长春市卫星路—前进大街交叉口作为研究对象,开展丌形交叉口的研究。首先细化异形交叉口分类,提出“丌”型交叉口的定义;其次,剖析丌形交叉口行人过街难产生的原因;最后,根据交通管理与控制需要,优化该交叉口信号配时方案,完善道路交通安全设施设置,为进一步优化城市道路丌形交叉口设计提供了参考。With the acceleration of expressway construction in our country,urban road intersections are facing difficulties in pedestrian crossing and frequent violations due to the intersection of multiple lanes,mixed traffic of people and vehicles,and insufficient safety facilities.This has attracted widespread attention to the study of complex intersections.This article selects the intersection of Weixing Road and Qianjin Street in Changchun City,which has typical characteristics,as the research object to carry out the study of open intersections.In the study,the classification of irregular intersections was first refined,and the definition of“丌-shaped”intersections was proposed;Then,the reasons for the difficulty of pedestrians crossing the street at丌-shaped intersections were analyzed;Finally,according to the needs of traffic management and control,the signal timing scheme of the intersection was optimized,and the road traffic safety facilities were improved,providing a reference for further optimizing the design of urban road丌-shaped intersections.
