Traffic information system for sharp turning points on the mountain road

The performance and principle of traffic information system for sharp turning points on the mountain road consisted of STC89C52 MCU and on-Chip Radio Transceiver nRF905 are introduced. The paper presents the system realization with hardware and software. This system can identify vehicles accurately and transmit data steadily, so it improves security when the vehicles meet each other at the sharp turning points on the mountain road.
