RESEARCH ON THE SAFE DRIVING SUPPORT SYSTEM FOR WINTER ROADS

The driving environment of winter roads is very severe in cold, snowy regions because of slippery road surfaces that are covered with snow and ice, and poor visibility, which are caused by snowstorms. In order to prevent multi-vehicle collisions during periods of poor visibility, the Civil Engineering Research Institute (CERI) has been examining the application of ITS technologies for cold regions. This paper describes how, in 1999, the CERI and the Public Works Research Institute (PWRI) launched joint research on driving support technologies for winter roads. In this research, the PWRI was tasked with the development of a cold-region-specific sensor, and the CERI was tasked with the development of a pilot system and a danger-warning system that contained a high level of user acceptability. Since the road information board could be overlooked during snowstorms, the CERI examined a danger-warning system, which employed light-emitting delineators capable of giving continuous warnings. The research results are presented in the paper.
