A Simulation Study of Commercial Vehicle Rollover in Highway Ramp Section According to Vehicle Speed and Curvature

시뮬레이션을 이용한 고속도로 진출입로에서 차량속도와 곡선반경에 따른 상용차량 전복 연구

Rollover accidents are a common occurrence on the highway ramp section. At highway ramp section, unexpected situations might occur due to demand on complex steering control unlike routine driving maneuver in the main streamline. Commercial vehicles have higher risk of rollover due to their high center of gravity. In this study, the lateral acceleration causing rollover would be found. In addition, sections would be classified as dangerous and safe ones by confirming the maximum lateral acceleration for various speed and curvature.
