AbstractLong and steep downgrade section in mountainous expressway is the black point of traffic accidentwhich poses a safety hazard. Operating speed difference of vehicle is closely related to traffic accident. Studying on the vehicle safety under different operating speed difference, disposal method or technology can be determined to applywhich can improve the safety of mountainous highway.
