This paper aims at creating the integrated database using GIS for road management and driving behavior after spraying the antifreezing agent in Sapporo City, Hokkaido. By this database, the study clarified the relation between the behavior of automobile driver and the road condition in winter. Furthermore, this paper considered the conditions in the case of becoming easy to slide immediately after spraying of an antifreezing agent. In the method, the Antifreeze Spraying Data and AMeDAS Data link to the Road Management Survey Data. As the result, it became clear of analysis that the road condition, the maximum temperature, the lowest temperature, and the daylight hours influenced the slip level of winter road. During two hours from antifreeze spraying, when the road condition was the black-ice-burn, especially the automobile is easy to slip on the road. From this research, it is considered that the compatibility between databases creates the beneficial information for road administrators, traffic administrators, and road users.
