一、交通信息系统概述 在现代社会,城市道路经常发生交通拥挤。当对道路交通情况不了解,特别是在对某些道路可能拥挤、心存担忧的情况下,或在行驶过程中遇到事故引起的偶发性的交通拥挤,或发现前方交叉口车辆正大排长龙时,交通用户一定期望能够得到相关的交通信息,从而避开拥挤的路段或交叉口,找到一条理想的出行路线。交通信息系统正是这样的一套系统。通过向交通用户传播、发送一系列的信息,交通信息系统可以减少交通用户出行的不确定性和交通堵塞造成的延误,并使得交通用户更有能力把握和控制出行时间,从而从整体上提高运输系统的效率。
First, the traffic information system Overview In modern society, urban roads often occur traffic congestion. When you are not familiar with the road traffic situation, especially if you may be overcrowded and worried about certain roads or you may encounter accidental traffic congestion during driving or if you find that the vehicles in front of the junction are long queues , Traffic users must expect to be able to get relevant traffic information, so as to avoid crowded road sections or intersections and find an ideal travel route. Traffic information system is such a system. By disseminating and sending a series of messages to traffic users, traffic information systems can reduce traffic travel uncertainty and congestion caused by traffic delays, and make traffic users more capable of grasping and controlling travel times, thereby improving transportation as a whole System efficiency.
