In particular, the study aims to evaluate the level of accessibility offered by bicycling to the beaches, which are among the most visited and attractive places for tourists, before and after the implementation of a regional bike tourism network system. A GIS-based procedure was employed and the method comprised of three main steps: (1) data collection and preparation, (2) GIS analysis, and (3) assessment of results. We performed two main types of analysis using GIS. First, we delineated service areas around each beach for various distances.

Such large undertakings can disrupt the system and result in the suspension of some of the provided transit services. While there is a considerable number of studies that focused on understanding people’s mode choices during normal operations and short-term disruptions, little has been done to investigate travel choices during long-term disruptive periods. This paper aims at examining changes in travel choices during a long-term disruption that occurred during the COVID-19 pandemic in Montréal. Using two waves of surveys, it explores the impacts of the suspension of the Deux-Montagnes train line due to the construction of a new light rail system, the Réseau express métropolitain (REM), on the travel choices of users that previously used the train line. Associations between respondents’ travel choices and socioeconomics, users’ perceptions, and spatial factors were examined, while exploring the difference between users’ anticipated travel choices reported before the suspension and their actual choices during the suspension. The results show that only around one-third of the Deux-Montagnes line’s previous users continued to use transit, while many shifted to using cars to reach the same destinations. Nevertheless, a higher percentage of users who live within an 800-metre buffer from a closed station used alternative transit options during the closure than using cars. Respondents who relied on using cars were the least likely to report that they will use the REM service in the future. The study highlights the overlooked impacts of long-term service closures.</p></div>","PeriodicalId":46989,"journal":{"name":"Case Studies on Transport Policy","volume":null,"pages":null},"PeriodicalIF":2.5,"publicationDate":"2024-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141285926","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}

A set of interviews with a wide range of stakeholders is followed by a quantitative analysis of time delays and extra discomfort for pedestrians, as we measure both the horizontal and vertical detours on walking distance and time, due to having to cross on pedestrian overpasses and underpasses. We find that (i) the new suburban rail service is a source of social inclusion on a metropolitan scale (accessibility gains) and of social exclusion on a more local scale, due to a barrier effect (ii) the confinement of the railway produces strong negative impacts on pedestrians that need to cross the railway, by increasing walking times and by worsening their perception of security and comfort (iii) underpasses and overpasses increase between twofold and fourfold the time needed to cross the railway on average, relative to the case of at-level crossings, (iv) taking into account the increased physical burden and insecurity perceived on overpasses and underpasses, weighted walking times increase up to ten times relative to at-level crossing, and (v) women, elderly people and pedestrians with heavy luggage are more affected by the increased walking time. Traditional methods employed to analyse large-scale transport projects should assess the negative implications of the barrier effect on local communities, as well as the relief measures designed to reduce local segregation, especially in vulnerable communities.

Taking into account modal shift effects and related changes in externalities and reduced demand for car parking, the cost-benefit ratios of the measures would be much higher. Even though the presented logsum approach ignores these second-order effects and focuses exclusively on economic efficiency, it is still useful in practice for prioritizing potential measures. Apart from that, the results show that groups of cyclists benefit differently from certain types of measures depending on their student status, employee group, and the resale value of their bicycle.

One common approach involves lowering speed limits in an effort to mitigate the severity of crashes and improve overall traffic safety. Seattle, Washington has been lowering its citywide default speed limits on municipal roads since 2016, among several cities in the US. This research paper presents a comprehensive investigation of the impact of these speed limit reductions on various safety indicators, such as the crash frequency, crash severity, crash characteristics, crash type, crash location, contributing factors, and overall traffic safety performance. The study employs a comprehensive dataset encompassing several years before and after the implementation of lower speed limits. Data analyses indicate varying changes in crash severity distribution between before and after periods in Seattle. Fatal and incapacitating crashes in Seattle decreased by 19% after the initial speed limit lowering in 2016 and further decreased by 3% after the second speed limit lowering in 2018. Pedestrian-involved crashes experienced a 26% significant decrease while speeding-related had a 16% decrease after the city implemented lowering speed limits. There was also a statistically significant 4% decrease in property damage only collisions and a 7% decrease in parked car crashes. Distracted driving / inattention-related crashes also decreased by 4%. The Mid-Block (but intersection related) crashes saw a significant decrease by 6%, and Driveway Junction related crashes decreased by 1%. The findings provide insights into the effectiveness of speed limit reductions in enhancing road safety in urban environments. The findings contribute to the existing body of knowledge on speed management strategies and their impact on traffic safety.
