交叉口交通控制系统设计

Design of Intersection Traffic Control System

飞速发展的国民经济带来各个城市繁荣的同时,也在逐渐影响着如今的交通现状,合理的交叉口交通控制系统可以科学的引导交通流,分离相互冲突的交通流。赣州市文明大道、飞龙岛大桥和杨公路相交的交叉口,是老城区与黄金开发区主要交通通道的重要连接点。因此,本文选取飞龙岛交叉口作为研究对象,通过调查分析,重新设计了交叉口的控制系统,并比较改造前后的效果。比较结果显示,在新的控制系统下,交叉口的通行能力、饱和度、车辆延误等有所改善。

The rapid development of national economy brings cities boom, and at the same time, gradually influences the traffic status. A reasonable intersection traffic control system can scientifically guide traffic flow and separate conflicting traffic flow. The intersection, of Wenming Road, Dragon Island Bridge and Yang Road, is the important junction of main traffic channel between the old city and gold development zone of Ganzhou city. Therefore, this paper selects the Dragon Island Intersection as the research object, redesigns the intersection control system, and compares the effect before and after the transforming, by making investigation and analysis. Comparison results show that the intersection traffic capacity, saturation, and vehicle delay, etc. have been relatively improved under the new control system.
