城市郊区主干道路段开口设计方法

Design of Road Section Opening in Suburban Arterial Street

城市郊区主干道的特征是交叉口间距较大、车速较高、路段占道路总长的比例高。其主要功能是在保证安全的前提下使交通流快速通过。而该功能的实现受到道路沿线地块开发的影响,集中体现在道路进出交通流同主线交通流的相互影响上。为缓解上述问题,采用道路空间利用、进出通道管理等技术,对道路各类典型开口进行比较分析,提出路段隔离开口的设计方法。并提出了基于安全和道路运行效率的冲突区整合设计方法。

The characteristics of the suburban arterial street can be described as long intersection distances,high travel speeds and high proportion of section length.Its main function is to transit the traffic flow quickly on the premise of safety.But the realization of this function is influenced by the land development of roadside,which behaved in the conflicts between arterial-route flow and the access flow.To resolve it,the new technique of road space utilization and access management is adopted,and the means of road section opening design are presented.And integrated design of conflict zone in consideration of safety and efficiency is proposed too.
