Abstract: Aiming at the actual condition of public traffic communication management in China and the present situation of GPS technology development, this paper designs an intelligent transport system baesd on GPS, GPRS and GIS technologies, and gives its structure and working principle. Experimental results prove that the system is with high GPS orientation precision(±2 m), high efficiency and stability for GPRS information transportation(packet loss rate<1%), and the bus arrival time prediction is exact(accuracy rate>90%).

Key words: Global Positioning System(GPS), General Packet Radio Service(GPRS), Geographic Information System(GIS)
