Importantly, establishing a conducive legal framework and ensuring effective enforcement are crucial for improving RTS. This study aims to analyze the enforcement status of road traffic regulatory factors and provide suggestions for improvement. A set of structured questionnaires comprising thirty items measuring six dimensions of road traffic regulation was developed to gather data from 396 Nepal traffic police officers. Confirmatory Factor Analysis (CFA) was employed to construct the measurement model. The statistical analysis revealed that road traffic regulatory factors such as seatbelt, helmet, and license laws, along with insufficient penalties for violations related to drunk and distracted driving, speeding, and mobile phone use contribute to road traffic accidents. The findings highlight the pressing need for effective implementation of traffic regulations. To improve road safety in Nepal stricter penalties for drunk driving, speeding, and mobile phone use, advancing vehicle safety technology, formulating transportation safety policies, accrediting pre-hospital care providers, and safety auditing in road planning, construction, and operation are vital. The model developed herein provides valuable insights to policymakers to reinforce prevailing regulations for reducing traffic-related fatalities not only for Nepal but also for other countries encountering similar road safety challenges.</p></div>","PeriodicalId":36621,"journal":{"name":"Transportation Research Interdisciplinary Perspectives","volume":null,"pages":null},"PeriodicalIF":3.9,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S259019822400174X/pdfft?md5=7ce7400570a021ccabe2d5ebc776db44&pid=1-s2.0-S259019822400174X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141961522","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}

Meanwhile, those reliant on their motorized vehicles make up the largest travel mode group, followed by low-cost-vehicle users, captive riders of personal motorcycles, and car users. The model results also reveal that captive riders of personal motorcycles tend to be male and the youngest-old, while smartphone users are more likely to belong to the car users group. Walking ability constraints also significantly affect heterogeneity in older adults’ activity and travel mode, where those with no constraints on their ability to walk tend to be categorized as active older adult car users.

Remote operation could facilitate the development of autonomous vehicles in a safe and efficient manner by putting a human in the loop without the need for the human to be physically present in the vehicle. In the current experiment, three aspects of remote driving have been investigated in a driving simulator to evaluate the effect of i) latency, ii) type of task to perform, and iii) speed on a number of performance measures.</p></div><div><h3>Method</h3><p>Thirty-one participants drove in simulated rural (high-speed) and urban (low-speed) scenarios. Five hazards were created for each scenario and the participants drove each scenario three times with different latencies (baseline, +100 ms, and +200 ms). The latency condition was masked for the participants. The hazards were designed with the intention of creating challenging traffic situations. For example, in hazard one (H1) a car parked next to the road activates their turn indicators and then cuts into the participant’s lane close in front of the ego vehicle, forcing the participant to either brake or veer. Latency, type of hazard, and scenarios (high- and low-speed) were all within participants’ variables. Objective simulator data collected included variables such as reaction time, post-encroachment time, speed variation, distance to hazard, collisions, etc. Subjective data was gathered through questionnaires between each of the balanced latency conditions to assess trust, perceived control, realism of scenarios, and workload etc. After the completed drive, participants were asked to rate in which order they believed they had been subjected to the different latencies.

Overall, the experienced gamers drove with larger safety margins although they had not been told that the latency was varied. Speed, latency, and group characteristics were interacting in significant ways and affected performance measures.

We explore the extent to which private automobility will be reconfigured into a private electric automated mobility regime or substituted by a shared electric automated mobility regime that could effectively address societal sustainability challenges. We draw from the multi-level perspective of technological transition, develop a conceptual model outlining possible transition advancements towards private and shared electric automated mobility and review pertinent literature supporting such developments. Our analysis reveals that shared, particularly pooled, mobility emerges slowly (niche level). Key actors resist a shift from private to shared electric automated mobility for economic (vehicle manufacturers), instrumental, affective, symbolic (users and societal groups), tax-revenue, governance and administrative (public authorities) reasons (regime level). The private automobility regime receives only moderate pressure from the socio-technical landscape pertaining to safety, congestion and environmental issues and effectively reacts by electrifying and automating vehicles (landscape level). We conclude that the most likely transition will primarily entail privately-owned electric AVs as opposed to shared (especially pooled) AVs, unless a landscape “shock” such as a climate breakdown, energy crisis or a significant political shift towards collective mobility exerts substantial pressure on the regime. Hence, the socioeconomic benefits of the so-called “three revolutions of automobility” could be diminished.</p></div>","PeriodicalId":36621,"journal":{"name":"Transportation Research Interdisciplinary Perspectives","volume":null,"pages":null},"PeriodicalIF":3.9,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S259019822400157X/pdfft?md5=162c545343088e8ca1ae451b183465c1&pid=1-s2.0-S259019822400157X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141637194","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}
