TL;DR: An entropy-Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) Method to evaluate the urban rail transit system’s operation performance from the operator's, passenger's and government's perspectives is formulated.
Abstract: Urban rail transit system operation performance evaluation results are important for government, transit operators and passengers. In this paper, we formulate an entropy-Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) Method to evaluate the urban rail transit system’s operation performance from the operator’s, passenger’s and government’s perspectives. Firstly, we establish the evaluation indicator system with 8 indicators and a total of 41 sub-indicators, the operational data of the 41 sub-indicators will be used as the input of the approach. Second, we formulate our new approach to obtain the performance evaluation: the Entropy Weight Method (EWM) will be used to calculate the weight of each sub-indicator; the product of the corresponding probability and weight will be used to formulate the performance from operator’s, passenger’s and government’s perspectives; the TOPSIS will be used to calculate the comprehensive evaluation values and rankings of performance for each month. Third, the Chengdu subway with 34 months initial data will be chosen as the case study to test our new approach, the related suggestions to the government, to the passengers as well as the operators and managers will also be given.

TL;DR: The results of case study by using China data show that the SDM is more stable than EWM; sub-risk indicators with highest ranks belong to risk factors of Human category, which means the Human unsafe actions and behaviors are the most dangerous factors that influence the normal and safe operations of RDGTS.

TL;DR: In this paper, a human-oriented and organization-oriented risk analysis model is proposed to analyze the risk in railway dangerous goods transportation system (RDNGTS), and the analysis results of the case study show that the accident happened because of the dynamic and nonlinear interaction among the risk factors.
Abstract: In order to prevent accidents in the railway dangerous goods transportation system (RDNGTS), a 24 model is proposed to analyze the risk in this paper. 24 model is a human-oriented and organization-oriented risk analysis model. When this model applied, unsafe material conditions, unsafe human actions, individual factors, safety management system, safety culture and external factors should be analyzed one by one. After that, mutual influence path of the causes of the accident should be analyzed. Finally, the relevance among the four stages should be established and analyzed. The analysis results of the case study show that the accident happened because of the dynamic and nonlinear interaction among the risk factors. In actual operation, senior managers should focus on cultivating the safety culture of the company and establishing a complete security system. Middle managers should increase their training in emergency situations and related safety knowledge. The grassroots managers should focus on supervising the personal unsafe behaviors of front-line employees, supervising the unsafe physical conditions and increasing the safety participation level of front-line employees. Front-line employees should act in accordance with the rules and regulations, and should report to the grassroots management in time when there are any unsafe accidents. As a comparison, the FRAM also be applied to analyze the same accident. Finally, the contrastive analysis results of the two models are presented.

TL;DR: It is unsuitable for rapid urbanization development model in the mountainous areas that encapsulate ecological and environmental security as their main functions, so the government urgently needs to amend its 'one size fits all' policy system.
