By leveraging detailed emissions data and forecast scenarios up to 2050, the research quantitatively assesses the potential reductions in greenhouse gases and other pollutants under current and upcoming emission regulations. The findings indicate significant environmental benefits from stricter emission standards and a transition towards electric and autonomous vehicle technologies, with notable reductions in NO_x, particulate matter, and CO₂ emissions. However, the study highlights the critical dependence of these outcomes on integrating vehicles with cleaner electricity grids and higher market penetration rates of advanced technologies. The research provides critical insights into the effectiveness of emission regulations and technological advancements in reducing vehicle-related pollution to achieve the EU’s climate targets by 2050. It also demonstrates the importance of policy support for vehicle electrification and the rapid implementation of cleaner energy infrastructures.</div></div>","PeriodicalId":46989,"journal":{"name":"Case Studies on Transport Policy","volume":"20 ","pages":"Article 101398"},"PeriodicalIF":2.4,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143512451","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}

These services are provided by motorcycled food delivery riders (FDRs), who are often informally employed, poorly paid, and work under time pressure, which might increase the risk of traffic crashes. Until now, few studies have been concerned with the effects the Covid-19 pandemic has had on driving behavior, especially for FDRs. Furthermore, it remains unclear whether work conditions and financial vulnerability could influence driving behavior. In addition, related studies have been conducted in Europe, but research in this field in South America seems to be lacking. Therefore, this paper aims to identify the antecedents of risky driving behavior for FDRs in Brazil during the Covid-19 pandemic. Therefore, an extended framework based on the protection motivation theory was proposed. Data were obtained from 295 FDRs and were analyzed using Partial Least Squares Structural Equation Modeling. The results showed that working conditions and financial vulnerability positively affect their driving behavior. Additionally, coping appraisal has a negative and significant effect on risky driving behavior. The effect of threat appraisal on risky driving behavior was found to be positive, which could be indicative of a typical behavior of young drivers. Therefore, FDRs perform a risky activity due to long working hours and the pressure for fast deliveries. Also, to meet short delivery time, FDRs adopt a risky behavior (red-light running, driving while checking cell phones and not using safety equipment).</div></div>","PeriodicalId":46989,"journal":{"name":"Case Studies on Transport Policy","volume":"20 ","pages":"Article 101403"},"PeriodicalIF":2.4,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143520981","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}

We study how job density and its spatial distribution are influenced by the metro and the FAR. Applying this question to Bengaluru, the research focuses on an ex-ante quantitative assessment of how job density and economic activity may be impacted by the Bengaluru Metro under different scenarios of the FAR. The novelty of our paper is that we use <em>estimates of consumed FAR</em> at the municipal ward level and do not just use the regulatory FAR as most studies do. Estimating regressions of job density as the dependent variable, we find that the FAR consumed has the expected positive effect in increasing job density. We perform simulations based on FAR relaxation under various regulatory scenarios--the most aggressive, intermediate, and least aggressive, in addition to two scenarios representing the actual FAR consumed in southeast Asian cities of Seoul and Shenzhen which have policies requiring high FARs in metro transit corridors. In each of these simulations, we examine the effects of the relaxed FAR regulations on job density and wages, at the municipal ward level.</div><div>We find that the benefits in absolute job density are the highest in the scenario in which Shenzhen’s <em>estimated FAR consumption is assumed</em>, especially when there is at least one metro station in the ward. Further, with FAR relaxation, the job density is distributed across Bengaluru’s wards a lot more extensively than is the case currently. Using standard elasticities applicable for India, we extend the gains in job density via agglomeration benefits to wages and find that the most aggressive regulatory scenario yields the highest increase in monthly wages by 1.4 times on average the monthly wages in the baseline scenario. The policy implications and caveats are summarized which have implications for other cities in India and other emerging economies where investments in metro transit systems are occurring.</div></div>","PeriodicalId":46989,"journal":{"name":"Case Studies on Transport Policy","volume":"19 ","pages":"Article 101395"},"PeriodicalIF":2.4,"publicationDate":"2025-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143421150","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}

Due to the multi-level data structure, this study employs a hierarchical modeling approach to explore the correlates of intersection crashes and develop models by integrating hierarchical modeling with the binary logit model and negative binomial model separately to explain factors contributing to both types of crashes. The modeling results reveal that signal violation and stop sign violation crashes occur more frequently at intersections close to open spaces. Both violation crashes are more likely to occur in block groups with more low-income or under-educated households. Further, the crash frequencies are positively related to the distance from an intersection to its nearest law enforcement agency and negatively related to the number of police officers in an area.</div></div>","PeriodicalId":46989,"journal":{"name":"Case Studies on Transport Policy","volume":"19 ","pages":"Article 101390"},"PeriodicalIF":2.4,"publicationDate":"2025-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143438011","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}

Using structural equation models and examining path analysis, the user perception is mainly influenced by user satisfaction, satisfaction with transportation and infrastructure, and behavioral change is mainly influenced by factors such as visiting hours and changes in perception.
