AHP-Fuzzy Synthetic Evaluation on Traffic Safety of Highway on the Basis of Reliability
TL;DR: The fuzzy synthetic model was built by adopting AHP and fuzzy mathematics theory and has set up the evaluation index system of third class highway traffic safety with the help of safety reliability.
Abstract: Based on analysis of traffic safety of third class highway in western area,the text has adopted 28 more important influence factors as the evaluation index from eight aspects,which is natural condition,route condition,and roadside condition and so on.With the help of safety reliability,it has set up the evaluation index system of third class highway traffic safety.The fuzzy synthetic model was built by adopting AHP and fuzzy mathematics theory.The instance of G212 in Zhangxian Country of Gansu Province is calculated and analyzed with this method,and if the safety reliability satisfied the need,the results are agree with investigates of highway management department.The method can reflect the traffic safety of third class highway in western area.

TL;DR: In this paper, the authors advocate for a modeling framework that considers traffic safety equity as a focal point, which is defined as how appropriately and equally the impacts of transportation are distributed among different types of users.
Abstract: Traffic safety policies are still conventionally ranked on financial and environmental criteria in developing countries, yet the equity concept can be advantageously used as an integral part of the process of traffic safety policy making. Equity in transportation is defined as how appropriately and equally the impacts of transportation are distributed among different types of users. The main contribution of this research is to introduce traffic safety equity in transportation policy making. The authors advocate for a modeling framework that considers traffic safety equity as a focal point. The analytical network process overcomes the drawbacks of data intensive models that are so difficult to implement reliably in developing countries and recognizes the existence of complex interdependencies among traffic safety factors. The approach is demonstrated on the case of Tehran, Iran. In this study, seventeen transportation elements are grouped into four clusters (driver characteristics, roadway characte...

TL;DR: This paper assesses the planning design schemes of urban traffic facilities to rich the evaluation research of this field, and that will provide references for more widespread application of variable fuzzy evaluation method and model in future.
Abstract: Based on variable fuzzy evaluation method and model, which is suitable for evaluation with the characteristics of multi-hierarchy, multi-indexes, dynamic variable and fuzzy though, this paper assesses the planning design schemes of urban traffic facilities to rich the evaluation research of this field, and that will provide references for more widespread application of variable fuzzy evaluation method and model in future. Key words: variable fuzzy, evaluation, urban traffic, planning design scheme

TL;DR: An entropy weight multi-level fuzzy comprehensive evaluation model in power plant security on the basis of reliability identification and obtains the indicator weight of all levels in the evaluation system by the entropy weight method.
Abstract: In the paper, we establish an evaluation system in the study of four aspects such as people, regulation, equipment and technology management, field management and engineering construction. We present an entropy weight multi-level fuzzy comprehensive evaluation model in power plant security on the basis of reliability identification. Firstly, it identifies the reliability of power plant security evaluation system. Secondly, it can meet the condition that the system is reliable. Then it obtains the indicator weight of all levels in the evaluation system by the entropy weight method. Finally, it carries out a comprehensive evaluation in power plant security by the multi-level fuzzy evaluation method.
