However, there is an emergent need to understand how cycling in countries like Brazil, can be encouraged and supported, particularly among different sections of the population. This study investigates social-psychological antecedents of cycling within the Brazilian context using a large-scale dataset to verify the appropriateness of a model based on the extended Theory of Planned Behaviour (e-TPB). In-person interviews were conducted with people living in three large Brazilian cities – Brasília (<em>n</em>=1107), Florianópolis (<em>n</em>=1084), and Porto Alegre (<em>n</em>=1105) using a questionnaire including nine items from the e-TPB to measure attitudes, social norms, perceived behavioural control, intention, cycling behaviour, and habit. Multigroup analysis verified the model fit and invariance in structural weights by gender. Age and gender were revealed to be the only sociodemographic variables with significant influence on the components’ mean scores, with gender exhibiting the strongest influence. We concluded that the e-TPB allows us to explain cycling behaviour among this sample of the Brazilian population and that it is particularly sensitive to (a) other people's influence (b) personal habit (c) perceived behavioural control (d) belief in the ability to change one’s behaviour. Women were less likely to cycle and were less likely to be influenced by social-psychological components that could encourage this type of activity. Thus, we conclude that understanding the social and cognitive determinants of cycling can help to design more targeted policies for different sections of society.</p></div>","PeriodicalId":100771,"journal":{"name":"Journal of Cycling and Micromobility Research","volume":"2 ","pages":"Article 100026"},"PeriodicalIF":0.0,"publicationDate":"2024-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2950105924000172/pdfft?md5=2da4098633411191f85d1112d68494f6&pid=1-s2.0-S2950105924000172-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140631677","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}

Through a content analysis of posts from ten Facebook groups by cycling advocates, we identify six pairs of contending storylines and their key narratives.

Our results suggest that pre-pandemic, delegitimizing storylines resonate more strongly among the respondents. Peri-pandemic, a positive shift has occurred in the social representation of bicycles in Metropolitan Manila, as indicated by the emergence of legitimizing storylines. This does not mean, however, that this positive shift is complete and not challenged anymore.

For urban environments with a mass bicycle volume, bicycle traffic congestion is likely to occur. Hence, a thorough understanding of bicycle traffic flow is necessary for the assessment of cycling infrastructure and the development of traffic management strategies considering cycling efficiency. This study aims to investigate bicycle flow characteristics using microscopic traffic simulation. As bicycle flow performance is subject to the non-lane-based movement strategy and the behavioral heterogeneity among cyclists, various scenarios with different microsimulation settings are evaluated. Ultimately, we derive the functional form fundamental diagrams and macroscopic fundamental diagrams using a curve-fitting approach and an analytical method, respectively. Important macroscopic traffic flow parameters, such as capacity, critical speed, critical density, backward wave speed, etc., are estimated. The results show that lane width, overtaking incentive, and desired speed distribution are factors that affect bicycle flow performance. The distinct features of bicycle flow under different traffic states are identified by discussing the simulation outcome and comparing the estimated flow parameters. The findings can be utilized by future research regarding large-scale bicycle traffic flow modeling and control.</p></div>","PeriodicalId":100771,"journal":{"name":"Journal of Cycling and Micromobility Research","volume":"2 ","pages":"Article 100022"},"PeriodicalIF":0.0,"publicationDate":"2024-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2950105924000135/pdfft?md5=3a3bb14e2269ed5cd77b25f8ef006cb0&pid=1-s2.0-S2950105924000135-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140279875","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}

The objectives of this study are 1) to derive operating speed distributions for all Personal Mobility Devices in use on off-street “cycling” facilities in metropolitan Vancouver, Canada, and 2) to determine how PMD speeds are influenced by microenvironment factors including facility type, path grade, weather, and path traffic volume. Classified speed data for 27 PMD types were collected in 4 seasons at 12 sampling locations in Vancouver, Canada. Results from the 25,053 observations show that motorization increases speeds by 3, 10, and 13 km/hr for bicycles, skateboards, and scooters, respectively, which tends to homogenize average speeds across PMD types at around 20–24 km/hr. Motorization also decreases the effect of grade on speed by about 2/3rd. Even with motorization, bicycle and other PMD speeds rarely exceed the regulatory limit of 32 km/hr – except for sit-down electric scooters which have exceptionally high speeds. Scenario analysis indicates that even with large penetration rates of motorized PMD, a 30 km/hr design speed for off-street paths would still be appropriate, although less conservative.</p></div>","PeriodicalId":100771,"journal":{"name":"Journal of Cycling and Micromobility Research","volume":"2 ","pages":"Article 100021"},"PeriodicalIF":0.0,"publicationDate":"2024-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2950105924000123/pdfft?md5=7c67b564aeb16d4178ccd887b30a2c48&pid=1-s2.0-S2950105924000123-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140134977","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}

Cities and transportation agencies have attempted to overcome access disparities by establishing equity-oriented policy requirements for shared micromobility programs. Yet no clear picture exists of either their prevalence or specific components. To address this gap, we asked and answered two questions: 1) What equity requirements do shared micromobility programs include? and 2) to what extent are programs monitored and evaluated? We collected policy data for 239 shared micromobility programs across the U.S. We focused on equity requirements across three dimensions: process, implementation, and evaluation. We found that 62% of shared micromobility programs had at least one equity requirement, although fewer than half (46%) included more than one, suggesting potential challenges for travelers facing intersectional barriers. Less than one-third of programs (29%) included process-equity requirements for targeted outreach to marginalized or underserved communities. Implementation requirements included smartphone alternative (36% of programs), cash payment compatibility (33%), reduced rates (32%), multilingual services (26%), adaptive vehicles for users with disabilities (5%), and mandated geographic service areas (30%). Finally, while most programs (83%) required data reporting from private companies, far fewer published public-facing evaluation reports (27%) or specified compliance language related to equity (15%). The language and conditions of requirements varied dramatically across programs. Findings reveal implications for transportation policy, including a need for micromobility programs to focus on access and outcomes during program evaluation.</p></div>","PeriodicalId":100771,"journal":{"name":"Journal of Cycling and Micromobility Research","volume":"2 ","pages":"Article 100020"},"PeriodicalIF":0.0,"publicationDate":"2024-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2950105924000111/pdfft?md5=c9b575ec87898ab992ff99847c95934b&pid=1-s2.0-S2950105924000111-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140069354","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}

To date, little research has directly examined the role that shared micromobility programs play in supporting the travel needs of low-income populations. To fill this research need, this paper aims to evaluate a subsidy program for low-income riders by examining the demographics, usage patterns, benefits and barriers for low-income riders relative to general riders. We explore this aim using a survey of 1037 Lime customers from the United States, Australia and New Zealand. Lime operates shared e-bike and e-scooter programs in seventeen countries and over 200 cities around the world. They operate a program called ‘Lime Access’ that provides subsidized rides to qualifying customers. Using descriptive and comparative statistics, we find that Lime Access riders were more likely than general riders to be locals who use shared micromobility for utilitarian purposes (commuting, shopping) as a regular part of their daily travel patterns (35% of Access riders used Lime daily vs 7% of non-Access riders) and in combination with transit (44% of Access riders connected to transit on their last trip vs 23% of non-Access). Open-ended comments revealed the important role that Lime played in meeting the mobility needs of Access customers, especially customers with a disability or who do not own a car. The findings suggest that if cities want to expand the uptake of shared micromobility among low-income populations, they may want to consider agreements that incentivise or support the expansion of subsidized ridership programs.</p></div>","PeriodicalId":100771,"journal":{"name":"Journal of Cycling and Micromobility Research","volume":"2 ","pages":"Article 100016"},"PeriodicalIF":0.0,"publicationDate":"2024-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S295010592400007X/pdfft?md5=c949235a4d2d9cad8ac571ea6f6b99b4&pid=1-s2.0-S295010592400007X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139719569","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}
