# 幕阜山区公路安全风险评价研究Road Risk Evaluation of Highway in Mufu Mountain Area

Abstract: The standard to the vertical, horizontal main design index value of the highway is not at a high level in Mufu mountain area. The construction of life protection engineering is necessary imme-diately. According to the current security status of the highway, Safety Influence Factors are ana-lyzed and summarized, and then the safety assessment index system is proposed. “Guide for Im-plementation of Improve Highway Safety to Cherish Life Protection” is used to value the assess-ment indexes, and then the whole road risk evaluation for the highway could be proposed. It is easy and convenient to calculate the accuracy risk of the road with the risk evaluation table. It is clear which the more dangerous road is. It is the data foundation to conduct the work arrange-ment in life protection engineering construction.
