中文摘要: 利用可变情报板(VMS)发布行程时间信息是缓解交通拥挤的有效手段,提出了一种VMS行程时间诱导效益分析仿真系统,并对仿真系统进行设计与开发。运用该仿真系统对两起点两终点的路网进行建模仿真,仿真结果表明,VMS行程时间对于应对交通事件(如需求激增)引起的拥挤作用显著；驾驶员的信息关注率值越大,路网运行效益改善率越明显。研究旨在为相关部门设计、评价控制策略,优化路网运行效益提供辅助决策依据。
Abstract:Travel time displayed by variable message signs (VMS) is an effective way to release freeway congestion. This paper presents a simulation system for analyzing guidance benefit of travel time displayed by VMS. Taking a network with two origins and two destinations as an example, simulation results show that travel time displayed by VMS can release incident significantly, and guidance benefits improve obviously along with information concerned rates. This simulation system is effective for designing and evaluating traffic control strategies, and providing a basis for decision-making and references to relevant departments to improve the operational efficiency of freeway networks.
