CAR TRAFFIC INFORMATION NOTIFICATION SYSTEM AND NAVIGATION SYSTEM FOR NOTIFYING REAL TRAFFIC INFORMATION DIFFERENT FROM TRAFFIC INFORMATION ON GUIDE PATH BY REGISTERING AUTOMATICALLY GUIDE PATH

摘要

PURPOSE: A car traffic information notification system and a navigation system are provided to register the guide path automatically and get correct information by comparing real traffic information with traffic information on a guide path. CONSTITUTION: A navigation system includes a current position detector(10). The current position detector is formed with a GPS receiver for receiving a radio wave transmitted from an artificial satellite to detect a current position of a vehicle and a current date and time. A navigation system(N) further includes an input device(20) such as a portable remote controller in order to transmit necessary information to a microcomputer(30). The navigation system further includes the microcomputer, a storage device(40), a radio communication device(50), and an output device(60). A hard disk is used as the storage device. The radio communication device receives traffic information transmitted from a road traffic system(T) and transfers the received traffic information to the microcomputer. An information center(C) communicates with the navigation system. The information center includes a radio communication device(70), a server(80), and a storage device(90).
