The present issue of Transactions on Transport Sciences reflects the rich diversity and the evolving priorities of contemporary transport research. As cities worldwide strive to address the pressing challenges of urban mobility, safety, congestion, and sustainability, researchers are continuously expanding the boundaries of knowledge, offering novel insights and practical solutions. The studies presented in this issue span a broad thematic spectrum, addressing traditional and emerging transport modes, behavioural aspects, and infrastructural challenges, with a remarkable geographic variety ranging from Europe to Asia. Understanding urban mobility...
A comparative study of gravity models to assess the evolution of urban bicycle mobility

Transactions on Transport Sciences 2025, 16(1):4-13 | DOI: 10.5507/tots.2024.019
Gravity models are extensively used tools to understand mobility, providing an approximation of the volume of a flow as a function of distance and population density. In particular, specific gravity models have been proposed in the literature for studying the bike sharing systems (BSS) in urban areas. In this paper, we show how robustness to scale change in data pre-processing can be used as a criterion to select the best model for BSS usage, in addition to the usual criteria of quality of fit. In a second stage, the study of the recent evolution of BSS uses in large cities via a dynamical application of gravity models over rolling time windows. Exploiting...
The Effect of Countdown Timer with Running Text at Signalized Intersection: An Empirical Study

Transactions on Transport Sciences 2025, 16(1):14-20 | DOI: 10.5507/tots.2024.016
This study aims to analyze driving behaviour at signalized intersections due to the countdown timer. In the scenario, we also test the countdown timer with running text that lacks attention in the literature. We collect data on lost time, early start, number of vehicles passing per cycle, number of violations and vehicle's speed. In determining the signalized intersection for scenario implementation, we consider the volume of vehicles, the number of phases, and the geometric of the intersection in the city of Yogyakarta, Indonesia. The results show that the use of a countdown timer in traffic lights, whether with running text or not, is able to increase...
Drivers' Responses to Countdown Timer at Signalized Intersection

Countdown Timers (CT) have gained significant popularity in recent years not only in many countries but also in Indonesia, particularly in the provinces of Central Java and East Java. CT displays the remaining seconds in numbers clearly before switching the traffic light on or off after a period of time. Three seconds before the light is to be off, drivers prepare to slow down the vehicles. On the contrary, some speed up to hasten the vehicles. The contrast behaviors represent different responses to traffic signals in an intersection. There are contradictions found in a number of previous studies as using a CT has potential advantages and disadvantages....
A comprehensive examination of public transport user satisfaction in Indian megacities
Rupas Kumar Meesala, M V Raju
Transactions on Transport Sciences 2025, 16(1):28-34 | DOI: 10.5507/tots.2024.021
In recent times, traffic congestion has emerged as a persistent problem, critically affecting travel time, fuel consumption, and commuter stress, while also contributing to poor air quality and a reduced quality of life. This global problem is especially acute in Indian megacities, which have dense populations, massive vehicular fleet, and limited road space. Although public transport is considered a promising solution to traffic congestion and related emissions, the effectiveness and adoption of road public transport depend on the characteristics of the service. This study examines commuter satisfaction with public transport services in three Indian...
Development of Congestion Severity Index for Speed Humps Utilizing Fundamental Parameters and Clustering Techniques - A Case Study in India
Malaya Mohanty, Satya Ranjan Samal, J Cyril Santhosh
Transactions on Transport Sciences 2025, 16(1):35-43 | DOI: 10.5507/tots.2024.020
Traffic congestion has widespread negative impacts on the environment, urban development, and road safety, leading to increased commute times and heightened incidents of road rage and accidents. Evaluating congestion, particularly in relation to speed humps, becomes crucial due to their complex impact on traffic flow. Although few studies have explored delay estimation and lane-changing behaviour at speed humps, the larger issue of traffic congestion has received less attention. Recognizing and measuring congestion levels at these humps can be pivotal in devising specified strategies to alleviate the challenge. The present investigation focused on...
Is the Youth Aware of E-scooter Use Regulations? Evidence from the Region of Sicily

Micromobility became a trend over the last few years in many European cities, but also worldwide. This trend emerged after the appearance of many e-scooter sharing services, which mainly operated in a dockless way, i.e. without fixed stations. Shared e-scooters were initially recognized as an ideal transport mode for first/last-mile trips, that could be perfectly combined with other modes and mainly public transport. However, the excessive use of shared e-scooters created also several issues in the cities. These issues are mainly associated with traffic safety and public space invasion. The main cause for these issues was that the cities were not adequately...
Dwell Time Variability at Bus Bays at Six Lane Road of Araniko Highway: Impact of Passenger Attributes and Bus Variation
Raju Bhele, Bishnu Prasad Devkota
Transactions on Transport Sciences 2025, 16(1):50-59 | DOI: 10.5507/tots.2024.018
This paper investigates the variation in dwell time at bus bays along the Araniko Highway's six lanes road section, focusing on the impact of bus variations and passenger characteristics. Dwell time, defines as the duration a bus remains at a station for passenger to board and alight, plays a crucial role in transit effectiveness. Understanding the factors contributing to its variability is essential for optimizing transportation system. The study showed that passenger carrying kids, elderly passengers and children had the longest boarding times. Additionally, the presence of steps at door slows down the boarding and alighting process, resulting longer...
How do we teach safety and sustainability on the roads? Traffic education in 4th grade primary schools in Czechia through the eyes of teachers
Elisabeta Drimlová, Matúą ©ucha
Transactions on Transport Sciences 2025, 16(1):60-68 | DOI: 10.5507/tots.2025.004
Transport education (TE) is an indispensable part of basic education. It aims to improve road safety and promote healthy lifestyles and environmental sustainability. Using an online questionnaire, we mapped what TE looks like in 4th grade primary schools in Czechia. We received 644 responses from primary school teachers. According to their reports, the practical part of TE is mainly implemented in traffic playgrounds (86%). Schools also implement TE through lectures/lectures with outsiders, e.g. police officers (38%) and organize TE project days (30%). The emphasis on safe behaviour of pupils in traffic is evident in the TE. We recommend more intensive...
