在左转车流量较多且路口区域较大的交叉口,一般通过设置左待转区提高交叉口的通行能力,但待转区的设置会引起机动车的二次停车,造成通行效率低、油耗增加、污染加重。Abstract: The intersection capacity is generally improved by setting left-turn waiting areas,if there ate more left-turn traffic flows and the intersection area is large.But setting left-turn waiting areas will also cause vehicles secondary parking,which will result in increasing fuel consumptions and pollution emissions.
