Transactions on Transport Sciences X:X | DOI: 10.5507/tots.2024.023 
In this article, our goal is to analyse a small but growing movement of community bike workshops or 'bike kitchens' in Australia. Bicycles are reliable forms of 'active' travel for short and moderate length journeys, in an age where carbon emissions must be reduced and reuse, recycling and refurbishment of everyday objects like bicycles are increasingly identified as key elements of sustainability transitions in western countries. A community bike workshop is a not-for-profit community-based organization formed around the restoration and maintenance of bicycles. From interviews, surveys and participant-observation over several years in Australia and...

This study explores the carpooling potential among university students considering the various incentives, discounts, motives, and barriers. A questionnaire was designed and conducted with the students of Sohar University, Oman. The analysis of collected 250 samples showed that more than 60% of the students were willing to accept carpooling considering the various benefits and incentives. The ANOVA analysis revealed significant differences in interest in carpooling according to multiple segments of students based on age, marital status, vehicle ownership, driving a car, and study major. Factor analysis yielded four factors of encouraging variables...
Determinants Behind the Taste Variation in Discretionary Lane Changing Behavior of Drivers Facing Downstream Queues
Seyed Hamed Seyed Matin, Ali Abdi Kordani
Transactions on Transport Sciences X:X
Lane-changing behavior can significantly affect many aspects of traffic flow including capacity, shock waves, and safety. Therefore, it is imperative to understand the determinants behind lane change behavior. This paper investigates the determinants of lane-changing in congested traffic using video-recording as well as a survey approach. A mixed logit model was estimated to account for unobserved heterogeneity in lane-changing behavior across drivers. Estimation results show that all categories of explanatory variables including socioeconomic, driving style, and road environment have a significant effect on lane changing behavior. Besides, unobserved...
The Impact of Low-Cost Black Spot Treatment: A Case Study of a Multi-Level Bridge in Karachi, Pakistan
Afzal Ahmed, Ashar Ahmed, Mir Shabbar Ali
Transactions on Transport Sciences X:X
Treatment of high accident concentration areas plays a crucial role in safety improvement. This paper presents a detailed case study on data-driven identification, analysis, improvement, and benefit-cost evaluation of a selected black spot in Karachi, Pakistan. The black spots were identified based on the accident data collected from 2007 to 2015 at the Road Traffic Injury Research & Prevention Center (RTIRPC). Road safety audits and on-spot accident investigations were conducted to investigate the contributing factors. The black spot under consideration is a bridge passing over an interchange in the southern part of the city near the coastline....
Users’ Perceptions and Emotions Regarding Seaplane Services in Greece: An Analytical Perspective
Ioannis Sitzimis, Irini Dimou, Markos Kourgiantakis, Achilleas Kanellis
Transactions on Transport Sciences X:X
This study aims to investigate the attitudes and sentiments of transportation service users in Greece towards seaplanes and to assess seaplanes’ qualitative, economic, and environmental advantages and disadvantages compared to traditional ships and airplanes. The findings of this research are crucial for both businesses and the government. Companies can develop effective marketing strategies to promote seaplanes as a viable transportation option, while the government can make informed decisions based on the findings. By using structured questionnaires and conducting exploratory factor analysis, three key factors were identified, explaining 59.22%...
Studying near–miss accidents instead of crashes: psychometric characteristics of Near–miss traffic accidents scale in Lithuanian sample

Transactions on Transport Sciences X:X
Purpose. Road traffic accidents (RTA) still are a major problem that causes health problems or death. However, it is difficult to study RTA since relatively small amount of them happen. For this reason, researchers turn to near-miss traffic accidents as construct that can be related to RTAs. Though near-miss traffic accidents are included in research, evidence about reliability and validity of measurement instruments are still lacking. Due to that this study aim - to examine near-miss traffic accidents scale psychometric characteristics. Method. This research involved two different age (young and middle-aged drivers and older drivers) drivers’...
Why do hard restrictive demand management policies fail to succeed in developing countries? Cultural factors influence the acceptance of policies
Alireza Mahpour, Saeede Saeedi Sharivar, Parsa Zamani
Transactions on Transport Sciences X:X
Urban congestion and air pollution are persistent challenges in developing countries, often driven by high private vehicle dependency. While Transportation Demand Management (TDM) policies aim to mitigate these issues, restrictive measures such as driving bans frequently fail to gain public acceptance. Using the Value-Belief-Norm (VBN) theory, this paper investigates the factors affecting the acceptance of restrictive TDM regulations in Tehran, Iran. A total of 500 questionnaires were distributed to assess the impact of environmental awareness and cultural values on individuals’ transportation choices. The study utilized Structural Equation Modeling...
A mystery shopping survey tool to address the needs of vulnerable users at bus public transport stops
Georgios Georgiadis, Gavriella Gargani, Christos Matzaras
Transactions on Transport Sciences X:X | DOI: 10.5507/tots.2025.016
The Quality-of-Service (QoS) criteria for public transport are not consistently met for all passengers, particularly vulnerable groups such as women, older adults, and people with disabilities. Women frequently travel for caregiving, carry heavy items, and travel with children, underscoring the need for improved accessibility conditions and customer care. Additionally, they face risks of assault and harassment, particularly in overcrowded environments, which have worsened during the COVID-19 pandemic. Older public transport users prioritize safety, accessibility, and comfort, with key concerns including easy access, comfortable seating, and little...
