This study aims to shed light on the intermodal practices and demographics of e-scooters users in Barcelona, explores the potential impacts of regulatory changes on established transport habits, and assesses the adaptability of users to changing transportation options. Through a self-reported survey of 311 private e-scooter users, we find a notable prevalence of young men from lower socioeconomic backgrounds engaging in intermodal travel, primarily for employment purposes. To better understand how e-scooter riders integrate the device in their daily mobility strategies, we introduce the Intermodality Ratio (IR). A Generalized Linear Model (GLM) is then used to identify key demographic, socioeconomic, and geographic predictors of the IR, revealing place of residence as the most significant factor influencing intermodal behavior. Finally, we analyze participants’ anticipated behavioral shifts in response to the upcoming ban using a Multinomial Logistic Regression (MLR) model, which explores the sociodemographic factors affecting the likelihood of adopting alternative transport strategies.

Few studies examined nonlinear effects of factors on e-bike travel behavior. This study adopts the generalized additive mixed model to explore the travel behavior of household-owned e-bikes with the consideration of nonlinear effects of factors based on data from Zhoukou, China. The study confirms that there is a significant nonlinear effect of many factors on the travel behavior of household-owned e-bikes, with the nonlinear effects varying by factors. The lower the number of household bicycles, the higher the travel frequency of household-owned e-bikes. An increase in the number of household cars leads to a decrease in the travel frequency of household-owned e-bikes, and this effect becomes larger as the number of cars increases. The number of household-owned e-bikes is positively correlated with travel frequency, but the correlation weakens after more than 3 e-bikes. There is a negative correlation between the travel frequency of household-owned e-bikes and the number of persons older than 6 when it exceeds 4. The effect of the number of persons older than 6 on the travel frequency of household-owned e-bikes gradually increases when the number of persons older than 6 exceeds 3. Finally, this study puts forward policy suggestions regarding enhancing the attractiveness and competitiveness of household-owned e-bikes.

The representative survey was conducted with over 1,000 individuals in 2022, which demonstrates a widespread willingness to cycle as a means of transportation. However, this desire remains unmet due to inadequate infrastructure and an urban configuration that generally discourages cycling. The results show a need for recognizable, safe and segregated cycling infrastructure, though with differing perceptions between gender and age groups and between levels of urban density.

Cycling with children in low-cycling cities poses specific challenges, requiring high confidence and skills. Active travel-to-school programs aim to promote cycling among children, and one of these programs, Bike Bus, has recently captured considerable attention. Bike Bus is an initiative where families cycle together to school following a fixed route and schedule. This study aims to trace the origins of this initiative worldwide, explain the current momentum behind the movement, identify their diversity, and reflect on their long-term sustainability. We reached 431 Bike Buses through a mixed-methods design, including archival analysis, an online survey, and 22 interviews. Bike Bus had a plural origin in Europe in the late twentieth century. Moving more than 35,000 children in a week, its expansion has been driven by the joy it brings to participants, the growing interest in climate action, and social media. This is the first study that examines the characteristics of different Bike Buses and analyzes the particularities of this initiative. On average, the rides have 29 participants and travel 2.8 km. We compare route characteristics, participants, goals, and relationships with their respective city councils. Finally, while not all initiatives aim to last, access to long-term funding and committed organizers are the best enablers for sustainability over time. Bike Bus’ powerful nature lies in its simultaneous purposes: active mobility to school, activism, and joy. To ensure longevity, organizers could collaborate with local administrations to secure resources while maintaining advocacy for child-friendly cities.</div></div>","PeriodicalId":47824,"journal":{"name":"International Journal of Sustainable Transportation","volume":"18 12","pages":"Pages 1012-1025"},"PeriodicalIF":3.1,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143099967","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Further, there are no studies on user-type sensitivity toward instruments fostering the uptake of shared and pooled-use AV. The aim of our study is to contribute to fill this gap, to provide important knowledge for decision-makers to develop transport policies designed to foster future sharing of AV. To this end, we re-analyze data from a choice experiment with 709 participants together with individual user characteristics, collected within the Swiss Household Energy Demand Survey. Specifically, we analyze the role of socioeconomic and mobility characteristics, attitudes and values regarding sensitivity toward policy-relevant push and pull instruments to foster shared and pooled-use AV mode choice. We show that different types of user characteristics have an impact on AV mode preference and on the sensitivity toward the categories and types of instruments tested.

Many have suggested mitigation efforts that should be undertaken, but in general these approaches have not resulted in significant change or have ultimately been too expensive. Further, approaches have tended to be fragmented, a challenge for a global industry. There are some exceptions to this, including the International Civil Aviation Organization (ICAO)’s carbon offsetting mechanism, but when it comes to understanding actions at a national level, much remains unclear. While ICAO encourages its member states to develop State Action Plans (SAPs) to address the industry’s impact on climate change, limited research has sought to analyze their proposed actions. In the aftermath of the Covid-19 pandemic’s impact, many called for a renewed effort to mitigate aviation’s contribution to climate change which resulted in a significant number of new SAPs being submitted. As such, this study analyzed 61 SAPs produced in 2021 and 2022 to identify measures being pursued by states to reduce emissions from aviation. We were also interested in partnerships across countries, given the emphasis on collaboration within ICAO’s environment programs. Findings show that most countries have focused on mitigation measures projected to have smaller emission reduction potential in the long term and what evidence we found of more ambitious “deep” decarbonization efforts was largely in the early stages of development. Additionally, we find limited evidence of ICAO’s Buddy Partnership programs in the SAPs which signals a need to re-imagine these opportunities.</div></div>","PeriodicalId":47824,"journal":{"name":"International Journal of Sustainable Transportation","volume":"18 12","pages":"Pages 1086-1101"},"PeriodicalIF":3.1,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143099897","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
