Information Collection of Intelligent Traffic Based on IPv6

智能交通系统(ITS)可以为出行者提供各种路况信息，提高道路利用率，降低交通拥挤程度。交通信息采集是进行交通科学管理和合理控制的依据。论文研究基于IPv6的智能交通信息采集与系统架构，将车辆视为网络中的移动节点，采集各种交通信息，建立人–车–路–环境协调的智能交通信息系统，更好地为ITS服务。Intelligent Transportation System could provide all kinds of traffic information for travelers, releases the problem of traffic congestion by improving road utility, lowering the rate of traffic congestion and accidents. Traffic information collection is the key source for functions of traffic management and control. The paper researches the intelligent traffic information collection and system architecture based on IPv6, which constitute intelligent traffic information system looking the vehicle as mobile node of the network and collecting all kinds of traffic information, and establishes coordinate system of persons, cars, road and environment.
