The traffic accident rate and severity of mountain highways in China are high. Long downhill tunnels, as important sections, greatly affect the safety of the whole highways. Therefore, it is of great theoretical and practical significance to establish the traffic safety evaluation index system for long downhill tunnels of mountain highways to ensure the traffic flow and traffic safety. This paper expounds the design principles and functions of the evaluation index system, and constructs the traffic safety evaluation index system of long downhill tunnel of mountain highway initially. Then an importance clustering analysis of each index is carried out by SPSS software. Combined with expert opinions, the evaluation index system is improved and optimized, which makes the traffic safety evaluation index system more reasonable, practical and feasible. Combined with expert opinions, the evaluation index system is improved and optimized, which makes the traffic safety evaluation index system more reasonable, practical and feasible. So this system can guide and evaluate the safety of long downhill tunnel of mountain highway more actively and effectively.
