In 2008, China was hit by exceptionally severe disasters of low temperature, freezing rain, and snow, causing congestion on main line national highways linking core economic regions. These disasters seriously effected road traffic and the social economy. By analyzing temperature data gathered with mobile road surface detection equipment and by factoring in the effect of terrain, landforms, and climate, this study optimizes the location of road weather sites for the Jingshen expressway based on thermal mapping technology. It builds a road weather monitoring and warning service system that monitors in real-time, warns at different grades, provides information service, and plays an exemplary role in the Ministry of Transport's highway network alarm emergency service. It also provides a useful resource for expressway transport management under ice and snow conditions in winter.
