Investigation of rollover performance for Malaysia bus superstructure

Accidents involving bus rollover can be classified as one of the most fatal types compared to other types of motor-vehicle accident. There are various aspects that lead to occupant injury and fatality. Two prominent aspects are superstructure strength and occupant kinematics. This study deals with t...
