| 摘 要： | 无信号交叉口的许多交通冲突与左转车流有关.左转车流与对面方向直行车流存在冲突,也和与之相交道路的直行和左转车流相冲突.在无信号交叉口处适当地设置左转专用道,能有效地减少冲突,减少因左转车干扰而产生的延误,运用交通流理论、概率论和排队论知识,研究了在无信号交叉口处是否应设置左转专用道,设置左转专用道时的服务水平,左转专用道的设置与所考虑的相关因素之间的关系等,并建立了相关的模型.

| Abstract: | At unsignalized intersection,many traffic collisions have relation with the left-turn traffic flows.The left-turning traffic flow may collide with the straight and left-turning flows of the opposite direction and intersected roads.At the unsignalized intersection,setting propriety left-turning roads can decrease collisions and delay effectively.Whether the left-turning roads should be set up or not depends on the straight and left-turning traffic flows and the opposite directions,the intersection's geometry... |
