Research on Highway Intelligent Monitoring and Warning System Based on Wireless Sensor Network

摘要

The intelligent monitoring and warning system in highway fog section can realize timely forecast, early warning and information integration in low visibility condition. It can supply the scientific basis to highway decision-making management and technology to establish highway intelligent transportation system. The self-developed intelligent monitoring and warning system includes vehicle detector, camera, variable information board, ZigBee modules and controller EUC. The system can greatly reduce the traffic accidents caused by fog. Result shows that the system has high precision and reliability.
