摘要

In China, existing road maintenance standards and codes primarily focus on evaluating the conditions of the road usage in order to prolong the service life of the road, not taking into account road safety. Moreover, the existing safety evaluation system is imperfect, and the evaluation criterion and results are not intuitive or concise. Based on the application demands of the road maintenance management, this paper aims at providing a more objective and comprehensive evaluation model for road maintenance by taking road safety factors into account. Roadway sections and intersections were chosen as evaluation objects according to road differences, and five major factors affecting road safety were analyzed through both the angle of road geometry and the roadway environment. Field data were collected to obtain model parameters, and expert panel field evaluations were performed to validate the rationality of the evaluation criterion and evaluation model. Four levels (A to D) were used to evaluate road maintenance safety performance, with A indicating the highest road safety, and D indicating the lowest road safety, providing a scientific and accurate basis for road safety maintenance workers.
