以快速路主线通行能力最大、入口匝道排队长度及延误最低为目标,在分析城市快速路可变速度引导的基础上,提出快速路匝道感应控制算法,构建基于可变速度控制下的快速路主线与入口匝道协同控制模型.并利用实际城市快速路路段调查数据,采用VISSIM仿真软件对所建模型、算法进行了仿真验证,结果可知,文中提出的快速路协同控制模型算法可有效提高快速路主线通行能力,大幅降低入口匝道车辆排队长度及平均延误,减少车均行程时间.

In order to achieve the expressway main capacity maximum and on-ramp queue length and delay minimum,the paper,based on the analysis of urban expressway variable speed guide,puts forward expressway and ramp induction control algorithm and builds the expressway mainline and the on-ramp coordinated control model under variable speed control. The proposed model and algorithm are verified with survey data of actual urban expressway road and through the VISSIM simulation software. The results show that the fast road coordi-nation control model and algorithm could effectively improve the expressway mainline capacity and reduce on-ramp vehicle queue length and average delay,and decrease vehicle average travel time.
