短距交叉口交通问题及渠化、信控优化研究

Optimized Research of the Traffic Problem, Channelization and Credit Control of Short Distance Intersection

通过VISSIM仿真分析，针对存在的二次排队、进口道能力不足、服务水平低、开口过大等问题，对交叉口开口宽度优化、渠化设计、全向交叉口信号联控与非联控仿真对比及配时设计，较好解决短距交叉口存在的交通问题。

Through VISSIM simulative analysis, in view of some significant problems, such as residual queue, low level of service and large opening, this article optimizes the interse-ction opening width, channelization design, the simulation co-mparison of signal intersection joint control and non-joint con-trol, and solve the traffic problems of short distance interse-ction wel .
