Evaluation Method of Traffic Safety Maintenance of High-Grade Highway
2021
With the evolution of better highway services and larger traffic volume, the traditional maintenance management indicators
can no longer satisfy the demands of highway traffic safety. In order to ensure timely, fast, safe, and reliable highway
maintenance and repair, this paper proposes a road traffic safety maintenance evaluation method. The fuzzy maintenance
evaluation method based on the gray correlation degree is used to construct the safety maintenance evaluation model. The
damaged characteristics of the high-grade highway components are analysed. The parameters of the evaluation model
are established using the analytic hierarchy process, and the accuracy of the model is verified through experiments. The
results show that the safety service level can intuitively measure the maintenance and repair status of various transportation
facilities. When the safety level is 1 (above 87 points) or 2 (above 85 points), the road maintenance and repair are in good
condition and the road users have a high level of satisfaction on safety; when the safety level is 3 or 4 (80 points or less),
it reflects that there are weak links in the road components, and targeted maintenance repairs are required. The results
provide references for highway safety maintenance decision-making and improvement of highway traffic safety services
