Hospitalizations have been trending upward between 2011 and 2019, with a pause in 2020 due to COVID-19 lockdowns. In all categories, men sustain more injuries than women, though the number varies according to age and geography. The type of road user also affects collision patterns. The time-series projections demonstrate that the goal of zero fatalities in 2050 will not be achieved under the business-as-usual scenario. The findings highlight the necessity of focused interventions predicated on collision trends and demographics. This includes better infrastructure design, increased surveillance, and customized safety measures.</div></div>","PeriodicalId":46989,"journal":{"name":"Case Studies on Transport Policy","volume":"20 ","pages":"Article 101440"},"PeriodicalIF":2.4,"publicationDate":"2025-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143759115","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}

However, prior experience does not appear to have been combined with consumption value theory to explain attitudes towards electric vehicles. According to consumption value theory, value is multi-dimensional and product choice is influenced by perceptions of utilitarian and emotional value. The objective of this study is to evaluate the extent to which perceived values, emotions and experience influence attitudes and purchase intentions. As a high involvement decision, car buying is generally considered from a utilitarian, cost-benefit perspective. By considering the emotional and experiential facets of decision making, this study contributes to the literature and extends the theory of consumption values. The findings are based on a survey of older, higher income car buyers (n = 340), a segment that might convert from conventional to battery electric vehicles. Data analysis consists of partial least squares structural equation modeling. The results show that anticipated emotions, contextual change, charging anxiety and hedonic value have a significant effect on attitudes, which drive purchase intentions. The results show that prior experience is a double edged sword: although prior experience weakens charging anxieties, it dampens emotions. Several recommendations for policy makers and practitioners are made to promote the diffusion of battery electric vehicles in Australia and other laggard markets.</div></div>","PeriodicalId":46989,"journal":{"name":"Case Studies on Transport Policy","volume":"20 ","pages":"Article 101436"},"PeriodicalIF":2.4,"publicationDate":"2025-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143705617","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}

Municipal authorities in the United States have led the way with piloting e-scooters sharing schemes to consider how they are used and the impacts this has for the wider transport system. This paper reports a time series econometric analysis of the trip data derived from e-scooter pilots in Minneapolis, Louisville, and Austin which represent a climate gradient down the central United States. The analysis evaluates the link between ridership and prevailing weather conditions such as temperature, wind speed, precipitation alongside weather events such as thunder and fog. An autoregressive distributed lag model format is applied at both daily and hourly aggregations of e-scooter demand with specific attention paid to how consistent these models are across the three pilots.</div><div>The results indicate that demand in the subtropical climate of Austin is quite stable throughout the year while ridership in the more northern climes of Louisville and Minneapolis follows a seasonal profile of being high in summer and dropping off during winters. The parameters calculated for the meteorological elements for daily ridership are stable across the pilots, indicating that user response to weather conditions is reasonably consistent in different climates. Riders in Austin appear more willing to displace trips to attain better weather conditions, bringing trips forward when the temperatures are hotter and postponing trips when it is windy or raining. Hourly ridership models are less stable in terms of their results and require more focused research to further reveal their dynamics. Practical implications of these studies are that cities considering the introduction of e-scooter sharing schemes would benefit from examining demand patterns in similar climate regions to plan for suitable scales and seasonal operations.</div></div>","PeriodicalId":46989,"journal":{"name":"Case Studies on Transport Policy","volume":"20 ","pages":"Article 101431"},"PeriodicalIF":2.4,"publicationDate":"2025-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143716039","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}

With the global rise in EV adoption, establishing an efficient and accessible charging infrastructure is crucial. Charging stations play a vital role in facilitating EV adoption by providing convenient locations for vehicle recharging. However, research assessing the effectiveness of charging stations in meeting EV users’ demands and ensuring their coverage in Thailand is limited. This study evaluates the distribution of public charging stations in Bangkok, Thailand, by analyzing spatial accessibility and considering access limitations and service capabilities. Location-allocation analysis in ArcGIS Pro is employed to assesses the coverage of existing charging stations relative to estimated charging demands. Questionnaire survey results, including EV model and charging behavior information, are used to determine capacity constraints of each charging station. The sensitivity analysis was also performed to highlight the impact of operating hours and SoC regain levels on demand coverage and station selection. Findings reveal that existing public charging stations generally meet the charging demand, but capacity and distribution need attention. Additional charging stations are necessary in specific sub-districts to effectively meet the growing demand, and coverage decreases when considering peak hour constraints, emphasizing the need for strategic expansion. The sensitivity analysis results imply that flexible service strategies and demand-responsive planning are essential to optimize the efficiency and accessibility of charging infrastructure.</div></div>","PeriodicalId":46989,"journal":{"name":"Case Studies on Transport Policy","volume":"20 ","pages":"Article 101435"},"PeriodicalIF":2.4,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143705619","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}

Therefore, to accurately predict future public transit usage in order to achieve a sustainable public transportation system, it is essential to understand how each urban form indicator influences demand. However, most previous research has focused primarily on the Global North or China. Therefore, this study aims to fill that gap by analyzing the effects of urban elements on public transportation demand in a developing city. To do so, after a comprehensive review of relevant studies, effective elements of urban form were identified. Then, using spatial statistical analysis, a database of the urban form and travel characteristics was assembled, and random forest regression was employed to examine the relationship of different urban form indicators with public transit usage. The model achieved a good fit and, using a game-theoretic interpretability technique revealed that most variables had consistent associations with the findings from studies in other parts of the world. However, a few variables exhibited different associations, such as distance to educational land use. Additionally, some variables had opposite associations depending on whether they were at the origin or destination of the trip, such as distance from the city center. Therefore, it is concluded that the impact of each factor on public transportation demand should be evaluated on a case-by-case and an origin–destination basis.</div></div>","PeriodicalId":46989,"journal":{"name":"Case Studies on Transport Policy","volume":"20 ","pages":"Article 101430"},"PeriodicalIF":2.4,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143685585","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}

However, the game as is needs future adaptations to fit the local context of players better and have an impact on the co-creation of neighbourhoods.
