Abstract:

This study examined a road surface temperature prediction model in a snowy, mountainous region in Japan. The road surface temperature varied from one segment of the road to another. This was mainly due to the fact that environmental factors were unique at each road segment. In general, the road surface temperature reached its maximum point in the midday and reached its lowest point just before sunrise. However, in a rugged mountainous environment, the road surface temperature does not follow a simple diurnal pattern. This study demonstrated the necessity of road surface temperature predictions at a local scale, rather than a regional scale, since regional forecasts may not depict any local-scale problems, such as road icing. Icy surface conditions may develop for a small area or patches of small areas, and regional forecasts may lead to all-or-nothing solutions for such local-scale problems. This study used both geographic information system (GIS) and Global Positioning System (GPS) as tools. Results from the road surface temperature predictions are illustrated visually using a GIS program so that any potentially problematic road segments can be identified geographically at different times. The use of GPS facilitates the compilation of various data with respect to their geographic coordinates. The outcome of the study will help highway maintenance authorities focus their efforts more carefully on potentially problematic road segments rather than on the entire road system. Moreover, they could narrow the time window for maintenance activities, thus saving resources while providing safe road conditions for the general public.
