“…Different fare structures are mainly used as one of the indicators for evaluating passenger travel behavior, operator performance, and other aspects. For flat fare structure (FF) optimization, Wang et al [14] investigated public transit service (i.e., flat fare and frequency) operation strategies in a bimodal network. Jin et al [11] focused on a flat fare structure and found that low fares are preferable from the viewpoint of maximizing social welfare.…”

This paper analyzes government subsidies based on the service design (i.e., headway) and fare structures of an urban rail transit system while considering necessary financial support from the government. To capture the interactions among the operator performance, government subsidies, and passengers in an urban rail transit system, a profit maximization model with nonnegative profit constraint is formulated to determine the optimal fare and headway solutions. Then, the social welfare that results from the operator profit maximization model is analyzed. Finally, a numerical example from Changsha, China, is employed to verify the feasibility of the proposed model. The major results consist of optimized solutions for decision variables, i.e., the fares and train headways, as well as subsidies to the operator. The fare elasticity factor under two fare structures significantly affects fares and demand. As the fare elasticity factor increases, the social welfare gradually decreases and a deficit occurs at low fares and demand, while subsidies rise from 0 to ¥24658.00 and ¥38089.16 under the flat fare and distance-based fare structures.

“…Finally, a practical MSDEDM example of highway emergency is given to illustrate the effectiveness and practicability of the proposed dynamic fuzzy approach. Remarkably, the application implies that the fuzzy theory can well handle the uncertainty of real world in practice and have wide application prospect in other related fields, such as public transport [36][37][38], logistics network [39][40][41], and traffic management [42]. e method of the dynamic decision-making procedure would be a useful reference to the similar decision-making researches.…”

Emergency decision-making (EDM) is of paramount importance, especially when the emergency occurs. The evolution nature of the emergency, such as multistage, uncertainty, dynamic, and information updating, has been playing a key role in the dynamic emergency decision-making process. However, most existing studies ignored the aforementioned nature. Our approach accounts for the dynamics inherent to a real emergency decision-making process and presents a multistage dynamic emergency decision-making (MSDEDM) procedure of a dynamic programming model based on decision-makers’ psychological reference satisfactory degree. Firstly, interval-valued trapezoidal intuitionistic fuzzy numbers (IVTrIFNs) are used to depict the relevant fuzziness and uncertainty of information. Secondly, by considering the dynamic evolution process of emergency and the decision-makers’ psychological reference expectation effect, the principle of MSDEDM approach is presented. Based on the analysis, the dynamic model on the new psychological reference satisfactory parameter formula is presented to obtain the optimal satisfaction and weight of each stage. Then, the value utility function based on the DMs’ risk attitude is proposed to obtain the comprehensive value of each emergency alternative for each stage and achieve the ranking results of each stage. Furthermore, a case study involving the transportation emergency decision-making problem demonstrates that the proposed method can achieve selection of the optimal alternatives for each stage, as well as adjustment of the alternatives for neighbouring stages. Finally, the comparative analysis and sensitivity analysis for the results are used to further verify the feasibility and practicability of the proposed method.

“…Cantillo et al [20] designed a state choice survey that the subjects are faced with two alternatives, but they are allowed to choose an indifferent potion, such as ''both are the same'' and established a discrete choice model to inspect the individuals' choice behaviors with indifference threshold. Wei et al [21] and Wang et al [22] proposed the notion of indifference thresholds-based bi-modal equilibrium (ITBE) with the assumption of indifference thresholdsbased travelers' mode choice behavior. They indicated that the solution of ITBE might not be unique by assuming travelers have different indifferent threshold for different modes.…”

In this study, a Boundedly Rational Nested Logit (BRNL) model is proposed by introducing the concept of indifference threshold into Nested Logit (NL) model. In BRNL model, the traveler is assumed to choose randomly or in accordance with his preference if the expected cost difference between two alternatives is within the indifference band. Otherwise, the traveler will choose the alternative with the minimum expected cost. A nested method of successive average is developed to solve the proposed problem. Finally, the rationality of the model and effectiveness of the algorithm are proved by using a numerical example with three-mode transportation network. The results indicate that, different from NL model, the choices of the travelers in BRNL model do not depend on the costs always. The value of the indifference threshold will affect the choice probability. The larger the indifference threshold is, the less sensitive travelers are to the change of cost. In particular, if the indifference threshold is large enough, the travelers' choices will always depend on the preference.
