The large-scale urban network of Tel Aviv is considered, where data features such as speed are extracted from an array of Bluetooth sensors located at the network signalized intersections, while its signal plans represent the traffic operators’ commands. The obtained results show that: (i) including signal plan IDs and/or temporal features (month, year, day, etc.) in speed or green time duration prediction tasks can improve the performance; (ii) considering fixed cycle time steps enhances the prediction compared with non-cycle-time steps; and (iii) including Bluetooth features in green times prediction task resulted with a slight degradation in performance.</div></div>","PeriodicalId":36621,"journal":{"name":"Transportation Research Interdisciplinary Perspectives","volume":"32 ","pages":"Article 101482"},"PeriodicalIF":3.9,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144523099","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}

To date, data-driven solutions to address VRU safety often rely on official crash data, but these data are limited in reflecting total safety experiences of VRUs. Near-miss events, which occur when a crash involving a vehicle and a VRU is narrowly averted, also contribute to hesitancy to bike or walk, but comparatively little is known about their location and frequency relative to official crashes. To address this, we distributed a web-based survey to bicyclists and pedestrians in Reno and Sparks, Nevada, USA. Analysis of their survey responses reveals that most traveled as a VRU frequently and had concerns about infrastructure and their safety. Using an interactive map, 175 respondents identified 277 locations where they either previously experienced a near-miss or felt unsafe with traveling as a VRU. We deployed mobile roadside LiDAR sensors to continuously collect data over two 72-hour periods in October 2023 at the 10 most frequently identified intersections in the survey responses. We recorded 251 near-miss events between vehicles and either bicyclists or pedestrians using LiDAR trajectory data and the post-encroachment time (PET) near-miss detection method. Our results underscore the prevalence of near-misses, as only 26 official crashes were recorded at these same intersections over the previous five years. The observed high relative frequency of near-miss events underscores the importance of integrating near-miss events into countermeasure planning.</div></div>","PeriodicalId":36621,"journal":{"name":"Transportation Research Interdisciplinary Perspectives","volume":"32 ","pages":"Article 101514"},"PeriodicalIF":3.9,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144518879","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}

This includes genetic matching to reduce selection bias and the use of random parameters ordinal logistic regression to estimate the impacts of the barrier types on crash severity. Barriers were classified into three groups for the analysis: guardrails (i.e., semi-rigid), cable barriers (i.e., flexible) and concrete barriers (i.e., rigid). In order to make comparisons across barrier types, genetic matching was performed for paired comparisons (e.g., concrete vs. cable barrier) and then marginal effects were estimated to determine the differences in crash severity. According to the results, the cable barrier is associated with the lowest injury while the concrete barrier is associated with the highest injury levels. Guardrails are safer than concrete barriers and less safe than cable barriers. It is also found that if concrete barrier or guardrail is involved in the crash, there is 12.09 % and 7.69 % increased probability of an injury compared to cable barriers, respectively<strong>.</strong></div></div>","PeriodicalId":36621,"journal":{"name":"Transportation Research Interdisciplinary Perspectives","volume":"32 ","pages":"Article 101517"},"PeriodicalIF":3.9,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144518245","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}

This shift from a single-focus cost-benefit analysis enables consideration of differing priorities and issues for each group and offers quantified analysis to support the design and evaluation of policy in terms of rates of fleet change, consumer incentives and grant schemes, rebalancing of exchequer revenue, and the dynamic refinement of EV policy. Results demonstrate that EVs can deliver substantial benefits for car purchasers and costs for the exchequer.

Notably, the earlier delivery of the fleet electrification strategy assessed delivers three times the consumer benefits of the later EV adoption rate scenario. The analysis also highlights specific adjustments that could be adopted to improve the performance of the overall policy package, including insights for refining the electrification pathway strategy, further evidence for raising public awareness of EV benefits and costs, and recommended reforms for the tax system and EV grant scheme to achieve better revenue balance into the future.</div></div>","PeriodicalId":36621,"journal":{"name":"Transportation Research Interdisciplinary Perspectives","volume":"32 ","pages":"Article 101492"},"PeriodicalIF":3.9,"publicationDate":"2025-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144490214","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}

Within this evolving landscape, EV battery-swapping technology is gaining prominence as a compelling alternative to conventional charging paradigms. This technology offers tangible solutions to critical adoption barriers, such as extended charging durations and the substantial upfront cost of EVs. Furthermore, battery-swapping presents a significant opportunity to augment the overall usability and operational efficiency of electric vehicles. This review paper undertakes a comprehensive examination of the potential inherent in EV battery-swapping for developing countries, with a particular emphasis on the context of Sub-Saharan Africa (SSA). To achieve this, the paper critically analyzes China’s pioneering application and advancements in this domain, particularly highlighting the contributions of industry leaders like NIO. By elucidating the progress made in China, this work seeks to establish an analytical baseline that can inform further investigation, policy formulation, and infrastructure development in other developing nations across Sub-Saharan Africa and Asia.

It underscores the indispensable role of robust supportive policies, targeted strategic investments, and contextually appropriate technological innovations, such as battery-swapping, in fostering the effective and widespread adoption of EVs in developing countries.
