The system consists of three sub-systems of On-Board Information Collection Terminal (OBICT), Vehicle Operation Monitor (VOP) and Wireless Communication Network (WCN), which can collect and transmit the data of batteries, key components in work and vehicles' location in real time.
It established the model of vehicle operation of the fundamental section offreeway, and exploits the simulation software of vehicle flow under every kind of we-ather of six lanes freeway in two directions, and tests the creditability of the softwa-re.
By analysing the theory basis and study method of the simulation program of vehicle operation at signal junction, this paper dicusses the establishment of mathematical model of various kinds of operational states such as arrival, queuing, trace, conflict and so forth.
Based on a brief explanation of working principle,operating mode, basic feature and function of the system, this paper gives a detailed introduction to general arrangement, program structure and content of the system. It mainly discussed the "simulation program of vehicle operation" in the system.
The operation management system of urban public traffic vehicles with 3G technology has 4 functions: vehicle information dynamic inquiry, vehicle dynamic control, vehicle operation and vehicle grade management.
The terminal has the function of positioning,transmitting the shaken alarming information,transmitting the low battery alarming information,and can be used in the supervision of vehicle operation dispatch,the goods need positioned,such as cash-box,cars and so on.
