| Abstract: | Long and steep downhill mountain roads are usually the hazardous locations,especially for the overload and fast going heavy-duty vehicles which are more likely to occur to the traffic accidents.So the relationship between longitudinal gradient,grade length limit,vertical curve and safety is analyzed,which can be referred to improve the safety and optimize the profile design. |

| Keywords: | longitudinal gradient grade length limit vertical curve operating speed |
