Defining Maximum Intensity Levels for Pedestrians and Vehicles in Shared Space

Aneta Dostalova, Radim Dvorak, Josef Kocourek

Transactions on Transport Sciences X:X  

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...

From Performance to Policy: A Cluster Analysis Using Logistics Performance Index Data

M. Mujiya Ulkhaq, Chaterine Alvina Prima Hapsari, Reza Ardiyawan

Transactions on Transport Sciences X:X  

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...

Can Autonomous Vehicles Improve the Traffic Flow Efficiency in Heterogeneous Traffic Environments? A Simulation-based Investigation

Mithun Mohan, Kiran Gopal

Transactions on Transport Sciences X:X  

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...

The Economic Impact of Bike Lanes: A Systematic Review of Property Value Changes

Kusuma R. Haratama, Anita Susanti, Ari Widayanti, R. Endro Wibisono, Wahyu Hamdani

Transactions on Transport Sciences X:X  

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...

Socio-demographic Attributes in Demand-Responsive Transport Modelling: A Comprehensive Synthesis of the Literature on gender, age and income

Tiziana Campisi, Antonio Russo, Giovanni Tesoriere, Chiara Spadaro, Guilhermina Torrao

Transactions on Transport Sciences X:X  

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...

Quantifying the Effect of Smart Traffic Cameras on Speeding Patterns Through Structural Equation Modeling

Izza Anwer, Muhammad Rameez, Muhammad Ashraf Javid, Muhammad Irfan Yousuf

Transactions on Transport Sciences X:X  

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...
