This study aims to evaluate equity in cycling initiatives and their operational challenges by reviewing a wide range of cycling initiatives implemented in Auckland, New Zealand. The effectiveness of current initiatives with respect to various target groups or resulting beneficiaries is discussed, along with potential additional initiatives, barriers to implementing cycling equity initiatives in practice, and possible solutions to address such barriers. By interviewing policymakers, decision-makers, planners, designers, and transportation professionals, 44 cycling initiatives are identified. Results suggest that the geographical distribution of some of the current initiatives implemented could be more equitable. While some initiatives are equitable, there remain challenges with respect to their implementation. Additionally, there are limited initiatives focusing on the safety of female cyclists in Auckland, and no initiatives specifically aimed at Māori and Pacific people, groups that can both be considered disadvantaged with respect to cycling in Auckland. Potential additional policy initiatives include e-bike/bicycle subsidies, policy and law changes, education and awareness campaigns, better urban planning, policies aimed at making cycling easier, and better monitoring and evaluation. Barriers to the implementation of cycling equity initiatives in practice include sociocultural issues, financial constraints, poor planning, human resource limitations, and the built environment. Suggested strategies to help overcome some of these issues include adopting an equity lens and providing equity assessments for all initiatives, thus providing a wider coverage with respect to diversity in the population, enhanced engagement with the community, and the empowerment of people.

Smooth cycling can improve the competitiveness of bicycles. Understanding cycling speed variation during a trip reveals the infrastructure or situations which promote or prevent smooth cycling. However, research on this topic is still limited. This study analyses speed variation based on data collected in the Netherlands, using GPS-based devices, continuously recording geographical positions and thus the variation in speeds during trips. Linking GPS data to spatial data sources adds features that vary during the trip. Multilevel mixed-effects models were estimated to test the influence of factors at cyclist, trip and tracking point levels. Results show that individuals who prefer a high speed have a higher average personal speed. Longer trips and trips made by conventional electric bicycles and sport bicycles have a higher average trip speed. Tracking point level variables explain intra-trip cycling speed variations. Light-medium precipitation and tailwind increase cycling speed, while both uphill and downhill cycling is relatively slow. Cycling in natural and industrial areas is relatively fast. Intersections, turns and their adjacent roads decrease cycling speed. The higher the speed, the stronger the influence of infrastructure on speed. Separate bicycle infrastructure, such as bike tracks, streets and lanes, increase speed. These findings are useful in the areas of cycling safety, mode choice models and bicycle accessibility analysis. Furthermore, these findings provide additional evidence for smooth cycling infrastructure construction.

Case Studies on Transport Policy
... After reviewing these new technologies or tools, Palm et al. (2021) hypothesized that if implemented with equity in mind, they provide underserved populations with greater transportation options. This relationship has been validated by showing that microtransit reduced gaps for more disadvantaged travelers by allowing access to opportunities that are less concentrated along fixed transit routes (Bills et al., 2022;Liezenga et al., 2024). Further, when designing for these microtransit services, using service zones based on both horizontal and vertical equity yielded the most equitable outcomes (Bonner and Miller-Hooks, 2023). ...

... Owing to the qualitative nature of the study, only a small number of participants were needed to examine our research topic in-depth via focus groups (Daley and Rissel, 2011). Participants were recruited based on characteristics indicated in a survey that was the precursor to the focus groups acknowledging that cycling is not equally experienced (Jahanshahi et al., 2023). Focus groups were conducted across three living-lab test sites using a multi-city approach applying the same focus group/interview approach (Woods and Masthoff, 2017). ...

... Observability is not significantly associated (p > 0.05) with the perceived ease of use of undergraduate entrepreneurs regarding blended learning (Hypothesis 8 was rejected). If a blended learning program isn't designed with the end user in mind, then observability becomes much less significant (Versteijlen et al., 2023). ...

... Many industry experts now anticipate that full automation (Level 5) may not be achieved until around 2030. Significant market penetration is expected to follow and there might be full market saturation by 2055 [21]. Before fully autonomous vehicles are market-ready, understanding public acceptance of different levels of driving autonomous is, therefore, of paramount importance. ...

... Positive awareness, such as knowledge of quality features or positive brand attributes, can lead to positive word-of-mouth intentions. Research conducted by (Jalilvand & Samiei, 2012;van Wee & Mokhtarian, 2023;Wedari & Yasa, 2022;Vizano et al., 2021) shows the results that food quality, service quality and atmosphere are the main determining factors of WOM. So, it can be concluded that Awareness has a positive influence on word-of-mouth intention. ...

... In contrast, the research conducted by Cheng et al. in the Shanghai metro context revealed that high crowding levels led to noticeable shifts in departure times, with individuals showing a stronger aversion to arriving late than to arriving early [27]. Singh et al. observed that rail travelers' aversion to onboard crowding was inversely related to vaccination rates [28]. In addition, connecting transport may also affect residents' choice of departure time, as Yu et al. found that reducing the number of shared bikes reduces the earliest departure time for metro commuters, prompting them to depart earlier [29]. ...

... In this study, the Cronbach's alpha coefficients of the total scale and four subscales corresponding to four latent variables of travel philosophy, travel preference, perceived usefulness, and perceived risk were calculated to analyze the consistency of the data, as shown in Table 8. If the questionnaire results are reliable, the Cronbach's alpha coefficient of the total scale should preferably be above 0.8, or at least above 0.7 [47]. The Cronbach's alpha coefficient of the subscale is preferably above 0.7, or at least above 0.6. ...

... Deployment of AVs at any scale will have far-reaching societal, ethical, legal, and environmental implications. approach is crucial to address the potentially exclusionary nature of this technology (Martens et al. 2022), and to move toward inclusivity in all its dimensions; yet the ability to safely interact with wildlife remains a key challenge at the frontier of AV research. As core components of the future of transportation, AVs will have major implications for sustainability and biodiversity. ...

... Moreover, the provider-to-population indicator considers only the availability of intraregional resources, ignoring the spatial accessibility of interregional facilities that are particularly accessed by patients living at the borders not only at regional level [16,17] but also across countries [18]. Although the majority of national and international authorities still rely on these provider-to-population indicators, different methodologies have been proposed in the literature to overcome these limits [17,[19][20][21]. They are mainly based on the gravity-based focusing in the provision of healthcare services at different geographical scales (e.g., urban, regional, or national). ...
