| Abstract: | long and steep downhill roads are usually the hazardous location;the paper is based on the date on-the-spot survey,analysis of long downhill section of the road linear design of the safety factors,summed up the road acceleration model of downhill section.According to the relationship between the change of acceleration and traffic safety,proposed the change of acceleration is to be the quantitative indicators for the road safety evaluation,determined the evaluation criteria of the road linear design in downhill section,to evaluate their safety and rationality. |

| Keywords: | Downhill roads The vector of acceleration Safety evaluation |
