Evaluation of freeway traffic safety facility system based on attribute recognition
摘要
Abstract
In order to evaluate the performance of the freeway traffic safety facility system,an evalu-ation system of freeway traffic safety facility was constructed,and a comprehensive evaluation model was proposed based on attribute recognition theory.The processes of universal screening,prelimina-ry filter,and quantitative filter were adopted for the construction of the freeway traffic safety facility evaluation system.The range interval of each index for different evaluation levels was determined with relevant norms and guides.According to the attribute measures of both single and multiple inde-xes,the performance of the freeway traffic safety facility system was determined by using the confi-dence criterion.The K1 +242 to K3 +259 segment of the Tai-Gan Freeway was taken as the re-search object for a case study,and the performance of the traffic safety facility system was evaluated by the proposed method.The results show that the performance of the research object is good.The proposed evaluation method provides not only the overall system performance,but also the most sig-nificant factors which affect the system performance.It can be used as a theoretical basis for the re-form of freeway traffic safety facility.关键词
