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...

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...

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,...

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...

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...

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...

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...

Shared spaces are intended to accommodate pedestrians, cyclists and motorists on equal terms, yet practitioners still lack an operational tool for translating pedestrian–vehicle interactions into clear capacity limits. This study closes that gap by proposing a density-based delay model that expresses instantaneous vehicle speed as a function of local pedestrian concentration. The four free parameters of the model are calibrated with a genetic algorithm against a bank of pedestrian-vehicle scenarios generated in PTV VISSIM, allowing the analytical formulation to emulate the full microsimulation surface. Once calibrated, the model collapses rich...

Logistics performance plays a vital role in facilitating international trade and strengthening economic competitiveness by enabling efficient supply chain operations. The Logistics Performance Index (LPI), developed by the World Bank, evaluates countries based on six dimensions—customs, infrastructure, international shipments, logistics competence, tracking and tracing, and timeliness. Despite its extensive use, prior studies have focused primarily on ranking countries rather than identifying performance patterns and relationships within the dataset. With the increasing complexity of global trade, there is a need for advanced analytical approaches...

Autonomous vehicles promise numerous benefits for future mobility, including reduced stress for drivers, congestion, emissions, and energy consumption, as well as increased safety, road capacity, and efficient parking management. A detailed literature review revealed the scarcity of research on connected and autonomous vehicles in developing countries. The present study employs microscopic simulation to analyse the impact of autonomous vehicle penetration in the mixed driving environment prevalent in India. The simulation was carried out by modelling a typical autonomous vehicle (AV) and introducing it to various parts of a road network, including...

Bike lane infrastructure has emerged as a key element of sustainable urban planning, yet its impact on residential property prices remains context-dependent and methodologically varied. This study conducts a systematic literature review of six empirical studies from North America, Asia, and Africa, to examine how different types of bicycle infrastructure influence housing prices. The selected studies employ varied analytical approaches—including hedonic pricing models, spatial econometric regressions, and qualitative interviews, and span different geographic contextsfrom dense urban cores to car-oriented suburbs. Overall, off-street trails and...

Urban mobility is essential for quality of life, especially for vulnerable groups such as the elderly, as it ensures autonomy and participation in social life. While income can influence the choice of private vehicles as a mode of transportation for regular trips, the gender gap in transport and safety issues related to public transportation should also be considered. One transportation mode that has emerged as a key solution in areas that are often underserved or characterized by territorial inequalities is Demand-Responsive Transport (DRT). DRT is an on-demand transport mode with characteristics that lie between conventional scheduled public transport...

Exceeding speed limits is a significant factor contributing to accident risks, which, in turn, stands as a major cause for the 1.3 million global road deaths per annum, which translates to 3700 dead people every single day. The percentage of fatalities is increasing every year as a one percent increase in speed results in a 3.5-4% increase in deaths. Therefore, a critical issue was evaluated by investigating the effectiveness of speed enforcement smart cameras as a part of advanced information and communication technologies (ICTs) installed by the relevant government authorities in the metropolitan area for efficient traffic management. To understand...
