Evaluation of Vehicle Operation Status and Analysis of Influencing Factors at the Entrance and Exit of Urban Underground Road

In order to evaluate the operating conditions of vehicles at urban underground road entrances and exits and investigate the influencing factors of their poor operating conditions, a three-stage DEA model of vehicle operating conditions evaluation method was proposed. The research results show that after stripping the environmental factors and random influence, the operation efficiency of urban underground road entrances and exits generally improves, and the environmental factors have a significant influence on the operation efficiency of vehicles. Different environmental factors have different significant degrees of influence on each urban underground road entrance and exit. In addition, the environmental factors that influence the operation condition of entrance and exits are different. The entrance should focus on controlling the distance between the hole and the confluence nose end, the length of the interweaving area, the lane, and the slope, while the safety factors at the exit should be taken into account.
