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

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...
Factors Influencing Commuter Mode Shift Behavior in the Greater Jakarta (Jabodetabek) Area

Transactions on Transport Sciences X:X | DOI: 10.5507/tots.2025.017
Greater Jakarta’s traffic congestion, especially during rush hours, is worsening due to the high volume of commuters from surrounding areas (Bogor, Depok, Tangerang, Bekasi – Jabodetabek). Roads are packed with both public and private vehicles, including ride-sourcing options, contributing to increased air pollution from fossil fuel emissions. Encouraging commuters to shift to mass public transportation—such as KRL/Commuter Line, MRT, LRT, and buses—is one of the key strategies to improve the air quality. However, research on the factors influencing this shift in Jabodetabek area remains limited. To address this gap, this study...
Enhancing Urban Mobility: A Road Diet Approach to Improve Traffic Capacity and Pedestrian Safety
Kusuma R. Haratama, Peter Furth, Anita Susanti
Transactions on Transport Sciences X:X
Urban intersections often face the dual challenge of managing high traffic volumes while ensuring pedestrian safety. This study investigates whether road diet strategies—reducing travel lanes while reallocating space for pedestrians—combined with signal timing optimization, can improve both vehicle throughput and safety at complex urban intersections. The North Washington Street corridor in Boston, including City Square and Keany Square, was selected due to its congestion and long pedestrian crossing distances. Data were collected via sensors and manual counts in December 2022. Microscopic simulations were conducted in PTV Vissim, calibrated...
Investigation on Behavioral Attributes of Pedestrians at Railway Stairways
Jagannath Pattanaik, Ujjal Chattaraj, Aarohi Kumar Munshi, Ashish Kumar Patnaik
Transactions on Transport Sciences X:X
The objective of the present study is to statistically assess pedestrian activity in various railway transit stairway facilities within a railway station as a contrasting stage. In the four study areas of Bhubaneswar, Bhadrak, Lucknow, and Kazipet, pedestrian attributes are categorised based on age, gender, and physical activities (with or without luggage). This study compa res the flow activities of pedestrians in vertical movements, such as bi-directional routes, between males and females. The analysis evaluated maximum space values of 0.91 and 0.84 m2/ped. in Bhadrak and Bhubaneswar, respectively. The increase in the dimension of the pedestrian...
Exploring mode choice behaviour and preferences of transport users in small cities in South Africa: The case study of Bloemfontein
Everardt André Burger, Alison Chetty
Transactions on Transport Sciences X:X
This study investigates mode choice behaviour and transport preferences in Bloemfontein, South Africa, a medium-sized metropolitan area facing distinct transportation challenges related to accessibility, affordability, and limited modal integration. While urban mobility research in South Africa has largely focused on major metropolitan regions, smaller cities such as Bloemfontein require tailored, context-sensitive strategies to address their specific economic, spatial, and social dynamics. Adopting a pragmatic research paradigm and guided by the Theory of Planned Behaviour (TPB), this study employs a structured quantitative research design and an...
Impact of Socio-demographic Factors and Public Perception towards Different Levels of Autonomous Vehicles: A Case Study of Seoul, South Korea
Md Rizwane Muztaba Khan, Md Hishamur Rahman, Jinhee Kim, Joonhong Park, Jin-Hyuk Chung
Transactions on Transport Sciences X:X
The adoption of autonomous vehicles (AVs) promises significant benefits, yet public acceptance varies across different automation levels. This study examines factors influencing public concern over using Level 3 (conditional automation), Level 4 (high automation), and Level 5 (full automation) AVs among Seoul citizens. Analyzing survey data from 209 participants with a Seemingly Unrelated Ordered Logit regression model, the study identifies key socio-demographic and perceptual factors affecting AV acceptance. Findings reveal that younger individuals (aged 20–29) are significantly less concerned about Level 5 AVs compared to older age groups,...
