DOI: 10.1080/13588265.2018.1435481
Abstract: ABSTRACT Current numerical analysis of car–pedestrian accidents pays more attention to typical contact state, which means pedestrians collide with the front of vehicle, but less to untypical contact state, which means pedestrians collide with the… read more here.
