摘要
为缓解道路交通拥挤,减少交通事故,分析了合肥市翡翠路与汤口路交叉口交通特征、通行能力,研究了翡翠路与汤口路交叉口交通信号灯的现状及优化设计,使得交通问题得到一定的缓解,提高了通行能力,从基本的道路参数,如现状交通流量、饱和流率、及信号周期等求解出现状各个进口道的服务水平,最后使用VISSIM仿真软件对配时方案进行仿真验证和评价.
In order to alleviate traffic congestion and reduce traffic accidents,this paper analyzes the traffic characteristics and traffic capacity of the intersection between the Jade Road the Tang Road in the city of Hefei,studies the current situation of the traffic lights there and presents the optimization design,which alleviates the traffic and improve the traffic capacity. According to the basic road parameters,such as the traffic flow status,saturation flow rate and the signal cycle,the service level of each road is figured out. Finally the VISSIM simulation software is applied to test and evaluate the time plan.
