Title:

A Study of Safety-oriented Evaluation Model for Road Maintenance in China

Abstract:

In China, existing road maintenance standards and codes mainly focus on evaluating the conditions of the road usage to prolong the service life of the road, taking no account of road safety. Moreover, the safety evaluation system is imperfect, while the evaluation criterion and results are not intuitive and concise. In a view of deficiencies of the present evaluation system of road safety maintenance and management, this paper aims at providing a more objective and comprehensive evaluation model for road maintenance by taking road safety factors into account. Road intersection and section are chosen as evaluation objects according to road differences, and five major impact factors are incorporated in a four-level analytic hierarchy method, in order to derive a more objective and comprehensive evaluation system. Evaluation criteria are established for each indicator and their rationality is verified by Kendall’s W method. An evaluation model is thus developed based on synthetical index method, and parameters are calibrated by principal component analysis and weight factor judgment table. Field data are collected from Wenchuan road, Hutai road, and S20 road in Shanghai. This model is further validated through field evaluations and expert scores, the correlation coefficient of 0.9353, 0.8609 and 0.8832 are obtained. In comparison with other models, the R2 indicates that the model yields better results with higher coefficient of determination. Then, 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 program.
