4 其它国家的智能交通系统 4.1 日本的通用交通控制系统(UTMS) 日本的通用交通控制系统(UTMS)是由日本国家警察署(NPA)于1993年4月发起建立的新型交通管理系统,计划到2001年以后才能完成。系统的中心目标是在车辆和交通控制中心之间通过使用红外线信号标杆,实现交互式双向通信。系统的最终目标是实现交通的主动控制管理,即将交通控制管理中心对交通需求和交通流的控制管理措施准确无误地传输给驾驶员,引导驾驶员在行车中避开交通
4 Intelligent Transportation System in Other Countries 4.1 Japan’s Universal Traffic Control System (UTMS) Japan’s Universal Traffic Control System (UTMS) is a new type of traffic management system established by Japan’s National Police Agency (NPA) in April 1993 to plan After 2001 to complete. The central goal of the system is to enable interactive two-way communication between vehicles and traffic control centers by using infrared signaling. The ultimate goal of the system is to realize the active control and management of traffic, that is, to transmit the control and management measures of traffic control and management center to traffic demand and traffic flow to the driver accurately and guide the driver to avoid traffic during driving
