A design about automotive terminal in Intelligent Transportation management System
Abstract
This paper described a design method about automotive terminal in Intelligent Transportation management System (ITS). The so-called Intelligent public Traffic management System is based on such key theoretical research as the allocation of public work, bus scheduling, prediction algorithms and use of Systems Engineering Methods of munications, information, electronics, control, computer, networking, positioning technology, GIS and other new technologies in the Public Transport System, Then ,build a modern Information Management Systems and Control Transfer Scheduling mode to achieve a informational, modern, intelligent public transport’s scheduling, operation and management, In order to enhance public enterprise management and service level, to improve public transport enterprises operating efficiency and effectiveness, At the same time provide a more safe, comfortable, convenient public transportation service in information. The car terminal device as a key equipment of the system, mainly have following functions: to read the vehicle positioning information, vehicle operating conditions record, automatic reporting stop station, realizing munication between Management station and vehicle.
Keywords:GPS,ITS,Automotive Terminal
