Building of Road Weather Monitoring and Warning System Based on Jingshen Expressway

From the 21st century, accompanying global industrialization and rapid development of economy, the natural environment is getting steadily worse, factors affecting public security have increased, and unexpected incidents also occur from time to time. Through analyzing road surface temperature data gathered by a mobile road surface condition detecting equipment, and considering the effects of terrains and landforms as well as climate, this study taking Jingshen expressway as representation, studies optimizing methods of road weather sites based on thermal mapping technology. On these bases, a road weather monitoring and warning system was built. The system achieves to monitor adverse weather in time, warn and provide the information service on real time. At the same time, the system is also easy to operate for engineers and managerial personnel, and is playing a positive and exemplary role for highway network alarm emergency service that Ministry of Transport is carrying out.
