以安全为导向的道路养护评价模型研究
A Study of Safety-oriented Evaluation Model for Road Maintenance Program
摘要
Abstract
In a view of deficiencies of the present evaluation system of road safety maintenance and management,in-tersections and sections are chosen as evaluation objects according to road differences.Five major impact factors are incor-porated in a four-level analytic hierarchy method,in order to derive a more objective and comprehensive evaluation sys-tem.Evaluation criteria are established for each indicator and their rationality is verified by Kendall′s W method.An eval-uation model is thus developed based on comprehensive indices,and parameters are calibrated by principal component a-nalysis and weight factor judgment table.Field data are collected from Wenchuan road,Bao′an road,and S20 road in Shanghai.This model is further validated through field evaluations and expert scores,a correlation coefficient of 0.737 is obtained.In comparison with other models,the R2indicates that the model yields better results with higher coefficient of determination.关键词
