Social barriers include, for example, lack of adequate support from public transport staff. This paper aims to explore stakeholders’ perspectives on how the governance of public transport, and particularly the working conditions, can influence bus drivers’ behaviour, with a special focus of passengers with disabilities. Eleven representatives from different organisations in Sweden were interviewed, representing public transport authorities, national authorities, trade unions and others. All interviewees had a good understanding of the industry, particularly regarding procurement and labour conditions. They held senior positions and were involved in shaping transport conditions and making decisions that influence public procurement, working conditions and accessibility for the passengers. The results suggest that bus drivers in Sweden have faced increasingly difficult working conditions in recent years. Our interviewees link this to current public procurement practices and financially constrained contracts, which they believed can lead to increased workload and stress for drivers, and that can negatively affect the behaviour towards passengers and create accessibility barriers. Recommendations based on the findings include further recognition of the issues of creating an attractive profession, improve the working conditions, increase awareness of gender equality, competence (in procurement processes), further monitoring and evaluation.</div></div>","PeriodicalId":46989,"journal":{"name":"Case Studies on Transport Policy","volume":"22 ","pages":"Article 101607"},"PeriodicalIF":3.3,"publicationDate":"2025-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145105417","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}

However, safety–critical human factors like distracted driving or speeding can often happen without leading to a crash. Hence, a matrix is needed that could translate the contributing safety–critical events into crashes. Quantifying distraction events into crashes could bridge this gap, and comprehensive observational data on drivers’ distractions could help make this quantification. This study aims to build a framework for calculating the relationship between crashes and events by collecting distraction events in selected high crash corridors in New Jersey. On-road observational data was collected to capture distracted driving behaviors using a moving test vehicle. Crashes occurring at the study routes during 2015–2019, with ’distraction’ as the only ’driver contributing factor,’ were collected. Afterward, the distraction event-to-crash ratio was calculated for each 5-mile road segment, which helped determine the study routes’ riskiest segments (hotspots). After converting crashes to events, the potential crash cost savings for various levels of reduction in distraction events (5%, 10%, 20%, and 30%) were calculated. The results revealed that US9, US1, US22, and US130 were the riskier corridors, with at least one crash from every 30,000 distraction events. It was also found that roads with signalized intersections, three-lane roads, rural interstates, minor arterials, and positive medians had the highest number of hotspots. Non-parametric tests confirmed that arterial roads and roads with signalized intersections have significantly lower event-to-crash equivalence than the other types of roads. This study will help state and local agencies identify distracted driving hotspots in their jurisdiction and enable them to allocate resources for education, enforcement, or engineering solutions more efficiently.</div></div>","PeriodicalId":46989,"journal":{"name":"Case Studies on Transport Policy","volume":"22 ","pages":"Article 101604"},"PeriodicalIF":3.3,"publicationDate":"2025-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145049405","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}

In this article we extend the understanding of ride-hailing phenomena by proposing that structural gaps in public transit are key explanatory variables in the uptake and willingness to pay for ride-hailing trips. Building on an international survey in Mexico City, Bogotá, and Medellín, we develop a Structural Equation Model (SEM) incorporating latent variables expressing perceptions people have about features of ride-hailing and vulnerabilities in public transit. Results show that these variables are relevant. We also confirm that educational attainment and income are instrumental for ride-hailing trips, and that technology embracement is the most important variable to distinguish among levels of adoption. Findings inform public policy by focusing on the negative experiences of using public transit and how this could be generating more ride-hailing trips.

Although high-speed rail offers lower carbon emissions, its higher operational costs necessitate government subsidies to balance corporate profitability and social benefits. To address the policy design of subsidies for HSRE, we first employed the Hotelling model to characterize logistics enterprises’ mode choice behavior, thereby determining the demand for both high-speed rail and road. Subsequently, a social welfare maximization model was developed incorporating producer surplus, consumer surplus, government expenditure, and environmental impact, deriving optimal subsidy values under different pricing scenarios. Finally, a case validation analysis was conducted using the HSRE service between Kunming and Chengdu in China. The research reveals that the subsidy value is proportional to the price difference between the two transport modes under fixed-prices scenario—the greater the disparity, the higher the required subsidy. While under equilibrium-prices scenario, the optimal subsidy value depends not only on intermodal cost differentials and carbon pricing but also on cargo time value, transport efficiency, terminal handling capacity, and transfer costs.

The dangerous road behaviour of riders challenges traffic laws and presents a complex problem for labour protection. Therefore, it is necessary to develop a deeper understanding of how the mobility of food-delivery riders is shaped by power and inequality. This article claims that mobility issues should be central to understanding food-delivery labour, as existing research generally overlooks mobility theory. Chinese food-delivery giant Meituan’s management practice of dividing riders into different food-delivery modes provides a case study for examining how platforms create differences in mobility and intervene in riders’ labour practices. Between March 2023 and April 2024, the first author worked as a rider and conducted in-depth interviews with 20 riders in Beijing. This article first introduces the core differences between Meituan’s different food-delivery modes. Drawing on motility theory as an analytical framework, the study further finds that the division of food-delivery modes is based on the dominant power of food-delivery platforms over order allocation. Riders tend to choose the food-delivery mode with a higher order volume but lower unit prices and more management requirements to obtain more order resources. Consequently, the platform reduces labour costs by dividing food-delivery modes, while riders need to strengthen their mobility skills to meet the high mobility requirements of the mode they chose. For transport policy, more consideration needs to be given to improving riders’ access to mobility through transportation infrastructure and law enforcement to prevent riders from violating traffic rules as their preferred option for enhancing mobility.</div></div>","PeriodicalId":46989,"journal":{"name":"Case Studies on Transport Policy","volume":"22 ","pages":"Article 101603"},"PeriodicalIF":3.3,"publicationDate":"2025-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145049404","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}

As many women continued to join over the decades, one of the biggest challenges they faced was adapting to infrastructures that were originally designed for male workers. Even now, be it the control room, the engine cab, or even the resting rooms and toilets, hardly any spaces crucial to the loco-pilot’s work envision women as the primary users. As a result, women’s experiences of these masculine spaces involve constant negotiation with authorities, as well as social biases, to be able to drive trains and move ahead.
