平面交叉口待行区设置方法研究

Optimal Design of Waiting Areas at Signalized Intersections

在借鉴和参考国家相关标准的基础上,针对较大型平面交叉口提出了一种交通组织方式.研究了较大型平面交叉口施划机动车左转弯待转区、直行待行区,非机动车左转弯待转区、直行待行区,人行待行区标线和设置左转弯待转、直行待行、人行待行信号灯的交通组织优化方法,并设计制作了以单片机逻辑运算为主导的左转弯待转、直行待行、人行待行信号灯.在不进行大规模工程改造的情况下,能最大限度地挖掘交叉口固有的时空资源,进一步提高通行效率,对缓解交叉口拥堵具有一定的现实意义.

Based on the reference of the relevant national standards, a kind of traffic organization method was put forward for large intersections. Traffic organization optimization methods of the large plane intersections were researched. These optimization methods include delineating the left turn vehicle waiting area, straight vehicle waiting area, non-motor vehicle left turn waiting area, non-motor vehicle straight waiting area, pedestrian waiting area and setting left turn waiting, straight waiting, pedestrian straight signal lamp. The single-chip microcomputer logic operations was designed to control the signals of left turn waiting, straight waiting and pedestrian waiting signal lights. Without the large-scale engineering modification, this new design can better utilize time and space resources and traffic efficiency was further improved. It has certain practical significance to ease congestion at large signalized intersections.
