Japan and the United States have significant railroad systems with distinct characteristics. Examining how these differences are related to train accidents can guide the adaptation of safety improvements from one system to the other. This study conducts statistical and causal analyses of train accident data from both countries for 2001–2023. The results clarify how accident characteristics correspond to differences in infrastructure, equipment, and operational features. Similarities and differences in train accident characteristics between the railroad systems of the two countries were compared, and the adaptation of successful methods, technologies, and practices from one country to improve rail safety in the other was discussed. The findings of the study will benefit the railroad systems of both countries by encouraging cross-country research, industry collaboration, and technology transfer. The quantitative risk assessment framework developed in this study can be applied to other railway safety and risk benchmarking efforts.

Wholesale markets are crucial in urban supply chains, serving as key distribution hubs for mobile vendors within the informal sector. This study examines how wholesale market relocation affects the routing efficiency of mobile vendors and innovates how cooperative and non-cooperative behaviours shape the spatial distribution outcomes. Methodologically, the study develops an adaptation of the Clarke and Wright Savings Algorithm (CWSA), modified to the operational characteristics of mobile vendors. This approach extends the classical vehicle routing algorithm to decentralised/dynamic informal distribution systems, allowing the potential to cooperate by sharing customer base. The findings reveal that strategically planned market relocations can significantly reduce travel distance, whereas poorly located markets exacerbate routing inefficiencies. Cooperative behaviour further amplifies efficiency gains by reducing redundant travel and balances load distribution. Empirical analysis of the Segiri market relocation in Samarinda (Indonesia) indicated distance savings of 5.27 % under inclusive scenario, which could rise to 34.91 % in selective scenario.

This study examines the role of user satisfaction in explaining the modal shift from urban minibuses to motorcycle taxis in Palu, a secondary city in Indonesia. Applying the SERVQUAL framework and survey data from 300 respondents, five service quality dimensions—comfort, accessibility, safety, travel time, and tariff—were analyzed using Structural Equation Modeling (SEM). Findings show that travel time and accessibility are the strongest predictors of satisfaction, while comfort plays a lesser role, especially among motorcycle taxi users. This reflects a behavioral trade-off, where speed and convenience outweigh physical comfort. The validated model confirms the reliability of the adapted SERVQUAL constructs (CR > 0.70; AVE >0.50), supporting their use in urban transport research. Theoretically, the study presents user satisfaction as a key factor in modal shift behavior. Practically, it emphasizes the need for transport policies that recognize informal mobility and respond to structural service gaps in under-resourced urban contexts.

Aligned with China's 2030 carbon neutrality goal, this study investigates key factors influencing private car users' intentions to switch toward public transportation in the Yangtze River Delta. Utilizing structural equation modeling (SEM), the research examines both transportation modes' direct and indirect (via identification with public transportation) effects of quality attribute evaluations—psychological benefits, economic costs, environmental impacts, safety, and convenience. Results reveal that favorable evaluations of public transportation significantly enhance switch intentions, with psychological benefits exerting the most substantial positive direct effect. Conversely, positive evaluations of private cars notably reduce switch intentions, especially regarding environmental impacts. While indirect effects mediated by user identification are statistically significant, their impact is weaker than direct evaluations, highlighting the predominant role of direct quality attribute assessments in travel mode decisions. Policy recommendations include enhancing the psychological experiences of public transportation and raising awareness of environmental costs related to private cars, thus supporting China's sustainable transportation objectives.

The paper traces the status of various modes in 1947 and the role British rule played in evolution of these modes. The discussion then traces important policies followed in various modes in the country since 1947 and how they shaped the growth of each mode of transport. The paper brings out the efforts made in implementing an integrated transport policy across the country. It also highlights the failure in implementing an integrated transport policy by giving major areas of failure. Finally, the paper concludes by mapping the main idea behind policy aspects and outcome of the same and by giving the broad contours of the future policy directions stating that in the Indian context instead of a tightly integrated transport policy it would be better to provide a level playing field across all the modes and enable the modes to develop in the marketplace.

This study addresses the challenge of implementing new mobility concepts like Mobility as a Service (MaaS) in car-dominant societies such as Thailand. Employing an exploratory qualitative approach and Multi-Level Perspective framework, we analyze the impact of the existing automobility regime on MaaS potential in the Bangkok Metropolitan Region. The findings reveal landscape developments that reinforce car-centric transportation systems but also identify dynamics and mechanisms that could facilitate a transition towards MaaS. The study proposes interventions to encourage a shift away from private vehicle use and promote MaaS adoption, emphasizing the need for effective governance strategies. By filling a knowledge gap in understanding the interaction between automobility and emerging mobility concepts in Thailand, this research contributes valuable insights for both transport studies and socio-technical transition research. It highlights the challenges and opportunities for new mobility concepts in Southeast Asia contexts, underscoring the importance of policy interventions in steering the transition towards more sustainable mobility solutions.

Integrating emerging mobility services into existing transportation systems presents significant challenges. This study introduces an innovative mobility service model that combines Personal Rapid Transit (PRT) technology with low-speed autonomous vehicles to enhance mobility and improve first- and last-mile connectivity through on-demand, door-to-door services. To evaluate the feasibility of this model in a developed urban environment, VISSIM simulations were conducted, focusing on reallocating time and space resources at critical signalized intersections within the studied network. The analysis explored various configurations for PRT-dedicated lanes—including mid-roadway, roadside, and one-way layouts—and tested different signal timing strategies at two intersections in Kasugai, Japan. The findings highlight an optimal integration plan that ensures efficient PRT operations while minimizing disruptions to overall traffic flow. By aligning infrastructure design and signal control with the specific requirements of emerging mobility systems, this study addresses practical implementation challenges and provides actionable insights for deploying innovative mobility services.

This study analyzes the preferences of potential users regarding Japan’s new ride-hailing services, introduced in April 2024 under a non-competitive framework designed to avoid competing with the taxi industry. These services are predominantly operated by local taxi companies and are only available during limited hours. However, their preferences within this regulatory setting remain unclear. We consider the interaction between the regulation and the preferences. Best-worst scaling was used to understand preferences related to service attributes such as fare, driver information, and availability. We found that driver information is highly valued, with a preference for daytime availability and time-based pricing over dynamic pricing. Pricing affects adoption rates. Time-based pricing and fare reductions for additional passengers are seen as ways to increase usage. Furthermore, the findings indicated a preference for rides with fewer passengers, partly due to privacy concerns and discomfort associated with sharing rides with others.

This study investigates the relationship between vessel characteristics, specifically vessel type (VT), vessel size (VS), and vessel turnaround time (VTT). By analyzing data from 173 vessels that called at Chittagong Port, this study employs nonparametric Kruskal-Wallis and Dunnett T3 post-hoc tests to examine the impact of VT and VS on VTT. The results reveal significant differences in VTT across different vessel types and sizes. These findings suggest that VT and VS are critical factors influencing VTT, providing a novel theoretical framework for analyzing port performance. The study proposes that port authorities should consider vessel characteristics when formulating policies and allocating resources to ensure overall port efficiency. The proposed framework offers a valuable tool for future research and practical applications in port management, facilitating informed decision-making to enhance port efficiency.
