Improvement of Information Service System of Slippery Road Conditions and Evaluation of IT

This paper reports on a pilot program in Akita City (Japan) designed to provide road surface conditions information to automobile drivers, particularly in snowy regions. The pilot program was able to gather information about slippery road conditions from a small cadre of vehicles (n = 12) using the on-board electronic control unit (ECU); data was then sent to the internet homepage ( for the 2006-2007 snow season in Japan. This was the first project that provided this information to the public. The authors outline some of the results of this pilot project, including the benefits and areas that still need attention and improvement. They also report on the second pilot program, conducted in 2007-2008, which used taxis as probe vehicles for data collection.
