When a metro line experiences sudden interruptions, it can severely reduce passenger mobility and degrade the overall transportation system performance. Existing bus feeder programs are often inadequate in responding effectively to dynamic and real-time fluctuations in passenger flow during such disruptions, particularly when combined with complex road traffic conditions. We propose a novel hybrid metaheuristic algorithm for the emergency feeder bus routes with time-window constraints to address this issue. The algorithm combines the Max-Min Ant System (MMAS) and Simulated Annealing (SA) to enhance search performance. A Back Propagation (BP) neural network estimates the emergency demand at each affected station, using historical and structural factors. These estimates are integrated into the hybrid optimization process, improving routing efficiency. The model aims to minimize the total operational time of emergency buses, ensuring timely evacuation. A case study using Beijing Metro validates the model’s effectiveness. Results indicate a 1.7-hour reduction in total passenger travel time and an 84.7% decrease in computation time compared to the Gurobi exact algorithm. These improvements facilitate the identification of optimal feeder paths under varying traffic conditions. The study provides practical guidance for enhancing emergency response strategies in metro systems.</div></div>","PeriodicalId":36621,"journal":{"name":"Transportation Research Interdisciplinary Perspectives","volume":"31 ","pages":"Article 101461"},"PeriodicalIF":3.9,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144089483","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, studies emphasizing understanding psychological barriers receive little attention. This analysis aims to provide answers to the existing knowledge, by not only assessing young people’s attitudes on ride-matching app characteristics, such as live geolocation and information on destination, but also evaluating the level of comfort in sharing information using the ride-matching app. Data based on a stated preference survey that was distributed online to young people in Nicosia, Cyprus soliciting a sample over 1,200 respondents. Modeling techniques used in the paper comprised of statistical econometric models in the form of ordered probit models with random parameters. Results attempted to shed light on linking the importance of certain ride-matching app characteristics to the level of comfort. It is found that even though most female young people are associated with a higher ranking of ride-matching app characteristics, a minority is found to be linked with a higher willingness in sharing information.

This evaluation can assist in more effectively allocating government resources to support companies with superior environmental performance. Many criteria used to evaluate the environmental performance of companies involve uncertainty and ambiguity inherent in expert judgments. To address this issue, the present research aims to develop a new hybrid method for group decision-making in a hesitant fuzzy environment. The proposed method investigates companies’ green performance in Iran’s passenger rail transport industry. For this purpose, by combining the field experts’ knowledge and literature review, the framework of the decision-making problem is determined. The paper’s main contribution is to extend a hybrid MADM technique into interval type-2 hesitant fuzzy (IT2HF) environment. In this hybrid approach, the IT2HF SWARA (Stepwise Weight Assessment Ratio Analysis) is utilized to determine the weight of criteria, and IT2HF MARCOS (Measurement of Alternatives and Ranking according to the Compromise Solution) is applied to evaluate the alternatives. Moreover, the proposed approach provides a systematic way to aggregate the opinions of a group of experts through the use of hesitant fuzzy sets. At the same time, each of these experts can explain their opinions in hesitant terms. The data used in this research is obtained from a group of qualified field experts. According to their opinions, the performance of eight major companies that own more than 80% of Iran’s private railway fleet has been evaluated. To validate the results, sensitivity and comparative analysis are carried out. The results indicate the stability of the ranking achieved with the proposed approach.</div></div>","PeriodicalId":36621,"journal":{"name":"Transportation Research Interdisciplinary Perspectives","volume":"31 ","pages":"Article 101441"},"PeriodicalIF":3.9,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143906899","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
