abstract="It is inevitable to provide road users with adequate information on winter road traffic in Hokkaido, Japan, since severe driving conditions such as slippery road and poor visibility due to snowstorm are found everywhere. This paper investigates the expression of winter road information and its effects on drivers’ travel decision making, which resulted in the website user surveys conducted on the website of Northern Road Navi. The following results were obtained: (1) When visibility goes down below 500 m, road users consider changing their travel behaviors. When visibility is between 100 and 200 m, they decide to use alternate routes and some decide not to drive. When visibility is 100 m or less, most drivers decide not to drive. (2) Appropriately provided information on visibility and surface conditions helps drivers to choose less hazardous travel behaviors. (3) Willingness to change travel behavior is affected by how visibility information is presented. When visibility information is presented as images, road users show more willingness to choose less risky travel behaviors. (4) When surface condition is “very slippery ice,” the sense of driving hazard is very strong.<p />",
