1.前言 智能运输系统(ITS)是把先进的检测、通信和计算机技术综合应用于由汽车和道路构成的道路交通运输系统中,使道路交通管理全面智能化的一项大规模综合技术。从而,彻底改变道路交通面貌,大大提高道路的通过能力、运输效率和安全性。随着全球定位系统GPS的日益发展,这项高科技在智能运输系统中也得到广泛应用。目前,主要是应用在汽车导航及汽车的运营管理中。
1. INTRODUCTION Intelligent Transport Systems (ITS) is a large-scale integrated technology that integrates advanced detection, communication and computer technology into the road transport system consisting of cars and roads to make road traffic management fully intelligent. As a result, the road traffic landscape will be completely changed and the road capacity, transport efficiency and safety will be greatly enhanced. With the increasing development of global positioning system GPS, this high technology is also widely used in intelligent transportation system. At present, mainly used in car navigation and car operation management.
