摘要
随着环形交叉口交通量的增长,交通问题日益突出。交通设计和信号控制是缓解交通问题和改善交通现状有效技术措施。通过分析环形交叉口交通流特性采取措施,可控制右转、直行、左转3种车流在环道内通行,而对调头车流的控制有一定的难度。为此,结合信号控制方法分别介绍在环内、环口和环外对调头车流控制的几种方法。
With the increase of roundabout traffic, traffic has become more and more serious. Traffic design and signal control are effective measures to alleviate and improve traffic. Through analyzing traffic flow at roundabout and taking measures, three car flows, including right, straight and left, can be controlled to drive in roundabout lanes. However, there are some difficulties in controlling u-turn car flow. For this reason, this paper introduces some measures respectively in the roundabout and out of the roundabout based on signal control methods.
