Description

<p>In Hokkaido, Japan around 2,000 Deer-Vehicle Collisions (DVCs) occur every year, which is a serious problem from the point of view of traffic safety and ecosystem protection. Thus, it needs to consider countermeasures to avoid and/or decrease DVCs. However, there are few current researches to analyze the factors to causes DVCs for taking regional characteristics of multiple national routes especially occurring frequent collisions in Hokkaido into account. Therefore, in this research, the factors to cause DVCs was analyzed by applying negative binomial regression analysis to national route 44, 36, and 240 occurring frequent DVCs utilizing the latest DVCs data, roadside environmental data, and SPUE. As a result, it was concluded that the occurrence factors of DVCs are differs on regional characteristics of respective national route and also depend on roadside environment such as road structure and land use.</p>
