Norwegian county authorities’ management of road safety has undergone major changes since 2020, when a structural reform was implemented. County authorities merged into fewer administrative units, and took over the responsibility for administering the county roads. Because of this, county authorities had to establish new systems for managing road safety. The aims of the study are to examine: 1) Whether four county authorities have implemented living systems for road safety management, three years after the 2020 regional reform, and 2) Factors influencing whether safety management systems are living, including the impact of extensive reforms. The study is based on qualitative research interviews (n = 42) and an online survey (n = 392). The extent to which the county authorities have managed to implement living safety management systems and maintain their key road safety roles differs substantially. Multivariate analyses show that the most important factors influencing whether county authorities have been able to implement living systems are the safety cultures in the county authorities, and the extent to which respondents believe that the reorganizations related to the structural reform have required a lot of time and energy.

After two decades of psychological research into travel behavior, one would anticipate a thorough understanding of the cognitive processes guiding travel choices. However, the intricate and unpredictable nature of mobility dynamics often obstructs efforts to promote sustainable travel behaviors. While hybrid choice models (HCMs) incorporating latent variables prove invaluable in analyzing travel behavior, there remains a critical need for further exploration into effectively managing these variables. Typically assessed at singular time points, these variables pose challenges in analyzing individual characteristics based on their fluctuations. Moreover, deriving actionable policy implications from HCMs is challenging due to the inherent nature of psycho-attitudinal variables, which exhibit limited responsiveness to alterations in alternatives. Only a significant disruptive event could induce notable shifts in individuals’ psycho-attitudinal characteristics. The objective of this paper is to investigate two aspects: i) to study if and how norms, intentions and perceived behavioral control change after a strong shock such as the pandemic, and ii) to analyze the differences in the HCMs results estimated by using data collected before and after the shock. The study involves a panel dataset gathered during a VTBC Program which involved three phases, two of which before and straight after the first lockdown. Our results show that norms were less impacted by COVID-19 and lost importance post-lockdown. There was a notable decline in the intention to use sustainable modes and an increase in car usage, with significant differences in perceived behavioral control between those who maintain and those who change their transport modes.

Safety climate – the shared perceptions of safety’s importance within an organisation – is a strong predictor of aberrant driving behaviours. This study employs Partial Least Squares Structural Equation Modelling (PLS-SEM) on a sample of 110 tanker drivers at a major South African trucking company to model the relationship between safety climate and two classes of aberrant driving behaviours – errors and violations. A multilevel model measuring safety climate using organisation-level safety climate (OSC) and group-level safety climate (GSC) is followed, with OSC fully mediated by GSC in its effect on driver behaviour. The findings show safety climate has a significantly larger impact on driving violations than errors, as safety climate affects the driving behaviour largely through safety motivation, which has a greater impact on categorically intentional violation behaviours, as opposed to habitual, unintentional errors. The study also demonstrates that safety climate explains a larger portion of the variation in violations than errors, suggesting that violations may be more sensitive to changes in safety climate, supervisory behavioural integrity, and safety motivation. Interventions leveraging safety climate may thus be more effective at reducing violations than errors. Future research should investigate the precursors to driving errors, as addressing these may require remedial training rather than changes in safety climate to achieve substantial improvements.

Pedestrian safety has always been a concern at urban intersections, especially in low-income developing countries with higher casualty rates. As one of the cities with the highest pedestrian fatality rates in Iran, Mashhad lacks studies that pinpoint the causes of these crashes. The choice of appropriate methodology was guided by the two-fold objective of the study: first, disaggregating crashes into homogeneous clusters; and second, examining the effects of risk factors on pedestrian crashes while accounting for the inherent unobserved heterogeneity in crash data. The study compared the classification accuracy of modeling approaches using receiver operating characteristic analysis. By analyzing three years (2015–2017) of pedestrian crashes in Mashhad, this study identified risk factors associated with higher severity of vehicle–pedestrian crashes at intersections. The results show that models incorporating the heterogeneity effect, such as the cluster-aggregated model and the random parameter model, have higher classification accuracy for crashes than models that do not consider heterogeneity. Based on the risk factors associated with increasing fatal crashes, several low-budget and immediate countermeasures are suggested in the hope of improving pedestrian safety at intersections.

The adoption of Battery Electric Vehicles (BEVs) is pivotal for advancing sustainable transportation and reducing environmental impacts. Despite government efforts, BEV adoption in Thailand remains below expected levels. This study identifies and evaluates the barriers to BEV adoption through a comprehensive survey administered to 3,069 respondents across Thailand. Employing Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA), the study categorizes and quantifies these barriers, offering insights into the factors that hinder consumer acceptance of BEVs. The results reveal that ’Vehicle attributes’, including concerns about efficiency, range, and reliability, is the most significant barrier for both BEV and ICE users. However, the order and strength of subsequent barriers differ between these groups. For BEV users, ’Public Data’ and ’Lack of Benefits’ follow as major concerns, while ICE users prioritize ’Financial Barriers’ and ’Consumer Concerns’. Notably, BEV users generally perceive these barriers more strongly across all categories. Based on these findings, this study proposes targeted policy recommendations aimed at addressing these barriers for both current and potential BEV users. Enhancing vehicle attributes characteristics, expanding charging infrastructure, implementing educational campaigns, revising fiscal incentives, and rebranding EVs through effective marketing strategies are critical measures suggested. These interventions are designed to align with both BEV and ICE user expectations and catalyze the broader acceptance and adoption of BEVs in Thailand. This research not only contributes to the academic discourse on sustainable transportation but also provides actionable insights for policymakers and industry stakeholders to accelerate the transition to electric mobility.

The global pandemic in early 2020 significantly disrupted life for many families, and the trip to and from school was not immune to these disruptions. Parents and children alike made travel adjustments depending on their preferences with regard to personal health and safety, social distancing, and aversion to risk. Each school district and individual school also made decisions with regard to in-person or remote learning during this period of uncertainty.
In this study, a research gap was filled by examining the effect of the pandemic on school transportation-related decisions for hundreds of families living in the United States. An online survey was developed and administered with the help of Qualtrics, an experience management company. Over 600 responses were gathered from across three Pacific Northwest states. In addition to collecting demographic data about the respondents, the survey asked about travel mode choices and characteristics of the trip to and from school. The collective results were then analyzed to determine which factors directly contributed to pandemic-related changes in travel behavior.
The study concluded that parent education level, household income, and age of child were all statistically significant variables that affected behavioral change. Additionally, common travel assumptions associated with rural students, when compared with urban students, were confirmed. These factors included a greater reliance on a yellow school bus and lesser availability of critical infrastructure.

This study explored temperature fluctuations in dry shipping containers transporting wine and liquor along maritime supply chains. It also examined how these variations affect product quality, and evaluated the effectiveness of thermal foil container liners in mitigating temperature changes. Temperature trials were conducted from the South African loading depot and concluded at the first distribution centre in the United Kingdom. Ambient temperature sensors were placed on cartons of wine and liquor inside the thermal container liner and between the thermal liner and the door of the container. Weather data was also collected during the trials. Temperature profiles showed large fluctuations in temperature inside containers because of day and night cycles while the containers were stacked at the departure and destination ports, posing challenges for supply chain management. Descriptive statistics were used to analyse the temperature profiles, whereas logit analysis was used to determine the impact of the thermal container liner on the temperatures to which the wine and liquor were exposed. Blind tastings were used to evaluate product quality after exposure to temperature fluctuations. Results showed that thermal liners significantly reduced temperature variability, which is critical for maintaining wine and liquor quality. Despite this, blind tastings confirmed that some products were negatively affected by temperature deviations. The study recommends the use of thermal foil liners for maritime transport of wine and liquor to minimise product damage and financial losses. This finding is particularly relevant for exporters aiming to preserve the quality of their wine and liquor throughout long-distance shipping routes.

The COVID-19 pandemic generated significant impacts on transport policy. Exploring barriers and enablers to active travel through the lens of the practitioners planning for and promoting its uptake can uncover underlying mechanisms that shape travel choices and encourage more effective interventions. This study uses online survey data from practitioners working in the planning and provision of active travel related initiatives (N = 40), to understand international experiences, as influenced by the surge of interest in active travel during the pandemic. We base our investigations and analysis on two policy process theories – the Multiple Streams Framework and Punctuated Equilibrium Theory. Drawing tools and concepts from both, we provide a synthesis of international experiences with planning for active travel, and analyse how professionals perceive existing obstacles and opportunities for active travel provision once the immediate impacts of the pandemic have waned. Our findings reveal a pervasive adherence to the status quo – while certain policies temporarily adapted to accommodate the pandemic’s disruptions, the pandemic failed to trigger substantial actions for our sample. The primary challenge lies in the enduring dominance of car-centric cultures and urban form, suggesting both a lack of community understanding about the issues associated with car usage, and ongoing structural barriers of cities planned around cars. Notwithstanding, the emergence of active travel projects and strategies since the onset of the pandemic, coupled with increasing public awareness of active travel, could be valuable in laying the groundwork for future long-term changes, even if their immediate impact is not yet evident.

Cities with a growing population and complexity face urban crises related to road safety and mobility. Governments and collaborative stakeholders are introducing car-free day programs to address these challenges. In this study, a scientific criterion to identify suitable streets for such programs was established through a three-round Delphi study. The study involved twenty panelists from academia, city governments, international and local organizations, and freelance consultants. The panelists identified forty-six criteria clustered into six categories through open-ended and close-ended rounds, desk research, and insights from a car-free day workshop. The panelists reached a consensus on all categories and forty items. According to the results, the panelists reached a “good agreement” on three categories, environment, health & safety, land use & roadside, and mobility & accessibility; a “moderate agreement” on the three categories, namely, categories, geometry & functionality, and policy & governance; and a “weak” agreement on the one object, namely, social & economic. The relative importance index indicated that the two categories, “mobility and accessibility” and “environment, health and safety”, were considered the most important. The study suggests that these findings can potentially influence urban planning and transportation policies.

The study suggests that these findings can potentially influence urban planning and transportation policies.</div></div>","PeriodicalId":36621,"journal":{"name":"Transportation Research Interdisciplinary Perspectives","volume":"28 ","pages":"Article 101197"},"PeriodicalIF":3.9,"publicationDate":"2024-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142533227","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Transport agencies worldwide must operate with multiple strategic goals: safety, mobility, sustainability, and equity. In support of these goals, they employ experts from a wide range of disciplines, which often operate in silos. In many instances, the silos can undermine agency goals.
In this case study, I investigate the state department of transportation in the US state of Georgia, which cleared thousands of acres of roadside trees beginning in 2018 without public or environmental review. The agency’s stated aim was to enhance roadside safety. I interviewed staff in various agencies across Georgia to discover how this happened when the environmental costs were so great and when the agency employs so many experts in environmental and ecology roles. The findings justify a renewed focus on multidisciplinary efforts and training, enhanced federal regulations for DOT maintenance actions, and a call for more interdisciplinary transportation research.
