城市快速路入口匝道控制方案研究

Study on the Scheme of on-ramp Control for Urban Expressway

入口匝道控制是缓解城市快速路交通拥挤最有效的方法之一,系统构建快速路入口匝道控制体系是城市发展的必然要求。文章在分析城市快速路入口匝道控制原理及特点的基础上,设计了城市快速路入口匝道控制系统架构,并重点针对控制模块进行了定义和功能分析,采取"快速路主线容量为主,兼顾入口匝道排队长度"的控制策略进行了控制方案设计,并针对实例进行了仿真分析。

The on-ramp control measure is one of the most effective ways to relieve urban expressway traffic congestion. Building on-ramp control system is an inevitable requirement for urban development. Based on the analysis of urban expressway on-ramp control principles and characteristics, the authors design the urban expressway on-ramp control system frame. Aiming at control module, the functional analysis and definition are made, in which a control strategy of ＂giving priority to urban expressway main line capacity, taking into account the entrance Ramp length of the queue＂ is taken into the consideration of the design control scheme. Finally, simulation analysis is conducted with an example.
