For the drivers who live in snowy areas, it is necessary to know road surface condition before driving in winter season. However sometimes drivers feel difficulty to know real road condition because it varies place to place and time to time. To solve this problem, the road surface condition information system for the winter season was developed. In this system, ITV cameras are installed at roadside of several paths. The road surface images are to be distributed through Internet homepage, and then drivers can get real time information. This paper shows outline of the system, user's opinion and future development. According to the opinion of users, most of them drive carefully if they notice the road condition is slippery. However, the relation between the system and occurrence of traffic accidents was not clear.
