N2  - In previous paper, evaluation model for four-wheeled vehicle accident risk in hilly and mountainous area was considered using sideslip limitation speed by 3D measurement for road alignment. This paper aimed to improve the risk evaluation model by considering the risk for curve misrecognition, and verified using real accident locations. The distance where driver can recognize the forward curve from its starting point is shorter at the sharp curve compared to the loose curve. The curve misrecognition risk is considered to be the delay of the reducing vehicle speed before the curve. The points of road at the defined accident risk level of 0.75 and more are considered as dangerous location, and a lot of accidents occurred at the point by lane departure. Moreover, hazard map for traffic accident in hilly and mountainous roads was constructed using the accident risk evaluation model.<p />  <p>Language: en</p>
