In the regional context of South Africa, road and rail transportation play pivotal roles, yet a significant imbalance exists, posing sustainability challenges. This study aims to identify key factors influencing freight transport, develop empirical cost models, and simulate scenarios to achieve equilibrium in regional freight distribution. Employing survey research, data was collected from freight companies and analysed using inferential statistics and empirical modelling. It employed a utility choice function model for simulating scenarios conducive to achieving a balanced freight transport system. Findings suggest that currently, compared to rail freight, road freight transport dominates, leading to an imbalanced system. Critical factors that influence include load cost, loading/offloading times, fuel expenses, and travel duration. However, sensitivity analyses revealed that targeted reductions in travel time, loading/offloading times, load cost, and fuel expenses could lead to a substantial shift towards rail transport, promoting a more balanced system. This study provides actionable insights for stakeholders. By addressing influential variables, such as load cost, loading/offloading times, fuel expenses, and travel duration, the freight industry can work towards equitable coexistence of road and rail transport. This study highlights the prevalence of road-based freight transport in the region and demonstrates the potential for equilibrium through interventions in key variables.</div></div>","PeriodicalId":36621,"journal":{"name":"Transportation Research Interdisciplinary Perspectives","volume":"31 ","pages":"Article 101479"},"PeriodicalIF":3.9,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144205548","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The acceptance of such autonomous ridepooling (aRP) services by prospective users is essential for their successful adoption. Therefore, this qualitative study aims to uncover the relevant factors that determine aRP acceptance and to better understand the drivers and barriers of aRP acceptance using a user-centered approach. Through 18 semi-structured in-depth interviews with a diverse range of participants, the study revealed the significance of performance expectations with regards to safety, comfort, flexibility, sustainability, and social aspects in shaping acceptance for aRP. Notably, ambivalent attitudes and controversial perceptions of these factors as well as differences between public transport and private car users underscore the importance of customer segmentation and tailored strategies for the design and promotion of aRP services.

Such models need two key components − travel demands with high spatiotemporal resolutions and travelers’ sociodemographic information – to determine travelers’ acceptance and participation in SAV system. Existing SAV operations models used travel demand generation methods that either lack travelers’ demographics or only generate trips at a zonal level on a case-by-case basis. A scalable approach that can generate travel demands with higher resolution and linked household- and person-level sociodemographic is needed to enable better analysis of trips’ shareability and support SAV operations modeling. To address this gap, we propose a Household and Individual Trip-chain-based (HIT) travel demand generation model. The travel demands of household members are generated as chains of trips with spatial and temporal details that match the travel patterns of the individual’s as well as the household’s demographic profile. Using Miami as a case study city, we compared the proposed HIT model with a state-of-the-art activity-based model (ABM) to demonstrate its feasibility and validity. Results show that HIT model captures more complex travel patterns. We also used the travel demands generated by both methods as inputs to simulate SAV operation and found that using ABM to input travel demands in SAV operation models may overestimate the benefits of SAVs. Additionally, the proposed HIT model has the advantage of only requiring publicly available data as inputs, making it scalable nationwide.</div></div>","PeriodicalId":36621,"journal":{"name":"Transportation Research Interdisciplinary Perspectives","volume":"31 ","pages":"Article 101425"},"PeriodicalIF":3.9,"publicationDate":"2025-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143877400","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present scoping review aims to provide a comprehensive overview of current research on the relationship between MD and traffic violations, evaluate the methodologies used to measure road-specific MD, and identify gaps in the literature to inform future research. Seventeen articles were identified in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guideline extension for Scoping Reviews. PsycINFO and SCOPUS databases were searched for articles published between 2000 and 2023. This scoping review revealed several key findings: a) only two articles explicitly addressed and measured MD, while the remaining 15 employed measures implying MD without explicitly addressing it; b) a positive relationship between MD and traffic violations was found, with evidence suggesting an additional positive link between anger and road-specific MD; and c) theoretical overlaps were identified between MD theory, the Theory of Planned Behaviour and the Model of Retaliatory Aggressive Driving. In light of these findings, it appears relevant to consider the role of MD in traffic violations when developing interventions to reduce them. However, further studies are required to better understand the observed relationship between MD and traffic violations and the role of emotions in this process.

The findings reveal that financial factors—such as livelihood support and loan programs—are prioritized by drivers, while policy-related factors—such as cargo rate systems and consignment mechanisms—are more emphasized by industry workers and decision-makers.
