车流速度和道路安全性有非常密切的关系.通过信息和先进的车辆设备对道路上的车速管理是一种灵活的方式,智能速度顺应系统ISA就是其中之一.现在一个全欧洲的联合合作正在开始对ISA的潜力进行研究.本文介绍了ISA的概念和它在速度管理上可能的效果;该文阐述了ISA在技术上的实施和部署的最新情况,并调查了ISA在道路网络中的作用.最后介绍了一个微观模拟模型的详细方法,该方法可用于分析ISA在实际城市网络中的效果.
Traffic speed and road safety are closely related.With information and advanced vehicle equipment on the road speed management is a flexible way, intelligent speed adaptation system ISA is one of them.Now a joint cooperation across Europe is being Began to study the potential of ISA.This paper introduced the concept of ISA and its possible effect on speed management. This paper described the latest status of ISA implementation and deployment in technology and investigated the role of ISA in the road network Finally, a detailed method of microscopic simulation model is introduced, which can be used to analyze the effect of ISA in the actual urban network.
