近十几年来,世界各国交通拥堵、交通事故和环境污染越来越影响着社会经济发展和生活。虽然道路运输增长的需求可以靠提供更多的道路设施来满足,但是在资源、环境矛盾越来越突出的今天,道路设施的增长将受到限制,这就需要依靠提供除设施之外的技术方法来满足这一需求。智能运输系统(ITS)就是解决这一矛盾的途径之一,而且,其重要性正被越来越多的人所认可。
In the past decade or so, traffic congestion, traffic accidents and environmental pollution in various countries of the world have increasingly affected social and economic development and life. Although the demand for road transport growth can be met by providing more road facilities, the growth of road facilities will be limited in the day when the contradiction between resources and environment is more and more prominent. This requires relying on the provision of technical means other than facilities To meet this need. Intelligent transportation system (ITS) is one of the ways to solve this contradiction, and its importance is being recognized by more and more people.
