Cycling improves public health, is more space efficient than cars, and has very limited emissions. For these reasons, many cities are implementing cycling infrastructure to support people of all ages and abilities to benefit from this mode of transport. However, cities often face opposition, or “bikelash”. Since people's decisions and opinions on policies are often shaped by their morals, this study explores how morals, political beliefs, and personal characteristics influence support for cycling as a mode of transport. Using Moral Foundations Theory, which identifies six key morals that guide people's opinions: care (concern for others' well-being), fairness (justice and equality), loyalty (commitment to one’s group), authority (respect for leadership and tradition), purity (emphasis on cleanliness and self-discipline), and liberty (personal freedom and opposition to government intervention). An online survey of 1606 residents in the Montréal Metropolitan Area assessed these morals using the 30-item Moral Foundations Questionnaire (MFQ-30) and additional questions to assess the liberty moral, alongside political beliefs, transport behaviours, and support for cycling. Linear regression analysis found that right-leaning individuals showed lower support for cycling, with liberty (opposition to government intervention) and authority negatively associated with cycling endorsement. Loyalty, typically linked to conservative morals, was positively correlated with support, while purity, care, and fairness showed no relationship. Car ownership was associated with reduced support, whereas environmentally conscious individuals and those interested in bikeshare programs showed increased support. The findings highlight the role of morals and political identity in shaping attitudes, offering insights for policymakers seeking to address opposition and broaden public support for health promoting infrastructure.
骑自行车可以改善公共健康,比汽车更节省空间,而且排放非常有限。由于这些原因,许多城市正在实施自行车基础设施,以支持各种年龄和能力的人从这种交通方式中受益。然而,城市经常面临反对,或“bikelash”。由于人们对政策的决定和意见往往受到他们的道德的影响,本研究探讨了道德、政治信仰和个人特征如何影响对自行车作为一种交通方式的支持。运用道德基础理论,确定了指导人们意见的六个关键道德:关怀(关心他人的福祉)、公平(正义和平等)、忠诚(对群体的承诺)、权威(尊重领导和传统)、纯洁(强调清洁和自律)和自由(个人自由和反对政府干预)。一项对montrsamal大都市区1606名居民的在线调查评估了这些道德,使用了30项道德基础问卷(MFQ-30)和其他问题来评估自由道德,以及政治信仰、交通行为和对骑自行车的支持。线性回归分析发现,右倾个体对骑行的支持度较低,自由(反对政府干预)和权威与骑行支持度呈负相关。忠诚通常与保守的道德观念有关,与支持呈正相关,而纯洁、关心和公平则没有关系。拥有汽车的人得到的支持减少,而有环保意识的人和对自行车共享项目感兴趣的人得到的支持增加。研究结果强调了道德和政治认同在形成态度方面的作用,为寻求解决反对意见和扩大公众对卫生促进基础设施的支持的政策制定者提供了见解。

This paper addresses the challenges faced by cycling at intersections, which were initially built to accommodate car traffic. Using the concept of obduracy, defined as the resistance of infrastructure to changes in its original function, we analysed two behavioural measures: the recommendation for cyclists to ride in the middle of the roundabout, and a sign allowing right-turn-on-red at signalised intersections. Our data came from field observations and intercept surveys conducted at 15 locations in Lausanne, Switzerland. We found that the obduracy of intersections operates on three levels: how they are designed (planning, materiality, legislation), how they are perceived (social norms, legitimacy, expertise), and how they are experienced (interactions with other road users). Our findings highlighted that although most cyclists knew the two behavioural measures, they did not always use them, due to low legitimacy, difficulty of use, insufficient safety, or a lack of usefulness. This was specifically the case of riding in the middle of roundabouts: Although Swiss road safety campaigns regularly advised cyclists to do so, the perceived dangers of sharing the road with cars deterred many from following this recommendation. Another overlooked obstacle was other road users’ lack of knowledge of the rules for cyclists, notably right-turn-on-red, which could lead to negative reactions, dangerous behaviour and stigmatisation of cyclists (e.g. wrongly thinking they were running red lights). The paper underlines the limits of behavioural measures and the need for redesigning infrastructure. It also introduces a novel theoretical framework to analyse cycling infrastructure, which could be applied in other settings.
本文讨论了在十字路口骑车所面临的挑战,十字路口最初是为了适应汽车交通而建造的。使用顽固性的概念,定义为基础设施对其原始功能变化的抵抗,我们分析了两种行为措施:建议骑自行车的人在环形交叉路口中间骑行,以及允许在信号交叉路口右转红灯的标志。我们的数据来自于在瑞士洛桑的15个地点进行的实地观察和拦截调查。我们发现,十字路口的顽固存在于三个层面:它们是如何设计的(规划、物质性、立法),它们是如何被感知的(社会规范、合法性、专业知识),以及它们是如何被体验的(与其他道路使用者的互动)。我们的研究结果强调,尽管大多数骑自行车的人知道这两种行为措施,但由于合法性低、使用困难、安全性不足或缺乏实用性,他们并不总是使用它们。尤其是在环岛中间骑车:尽管瑞士的道路安全运动经常建议骑车者这样做,但与汽车共用一条路的危险让许多人放弃了这一建议。另一个被忽视的障碍是其他道路使用者对骑自行车者的规则缺乏了解,特别是右转红灯,这可能会导致负面反应,危险行为和对骑自行车者的污名化(例如错误地认为他们闯红灯)。这篇论文强调了行为措施的局限性以及重新设计基础设施的必要性。它还引入了一个新的理论框架来分析自行车基础设施,这可以应用于其他环境。

This paper explores the potential of e-cargo bikes as a personal transport mode in the UK, reporting on a series of surveys and trials. Hypothesising that early adoption of this niche mode was geodemographically skewed, we carried out a nationally-representative survey which showed that living in London, being aged 18–34 and being a less frequent car user were associated with e-cargo bike use. Additionally, we used an empirical mixed methods approach to understand what level of usage might be achieved via a supported trial in areas outside London which were relatively car-dependent. 49 households were loaned an e-cargo bike for a month in summer 2023, in suburbs of Leeds, Brighton and Oxford. Eleven of these households borrowed e-cargo bikes again the following winter. By Autumn 2024, 10 trial households had bought e-cargo bikes. High usage was achieved in the trials, with summer trial households cycling approximately 8000 km (38–42 km per household per week) with over 50 % of the distance travelled replacing car use. This work revealed a range of advantages of use as well as issues to address, including purchase costs, theft, negative perceptions of battery safety and a lack of e-cargo-bike appropriate infrastructure. The study demonstrated that there are current non-adopter groups of people in the UK for whom e-cargo bikes represent a realistic and desirable form of mobility, with the potential to reduce car use and associated emissions, and with possible benefits for health and family activities.
本文通过一系列调查和试验,探讨了电动货运自行车在英国作为一种个人交通方式的潜力。假设这种利基模式的早期采用在地理人口统计学上是倾斜的,我们进行了一项具有全国代表性的调查,结果显示,居住在伦敦、年龄在18-34岁之间、不太经常使用汽车的人与电动货运自行车的使用有关。此外,我们使用了一种经验混合方法来了解在伦敦以外相对依赖汽车的地区通过支持试验可能达到的使用水平。2023年夏天,利兹、布莱顿和牛津郊区的49户家庭获得了为期一个月的电动载货自行车贷款。第二年冬天,其中11个家庭再次借用了电动载货自行车。到2024年秋季,已有10户试用家庭购买了电动货运自行车。在试验中取得了很高的使用率,夏季试验家庭骑行约8000 公里(每户每周38-42 公里),超过50% %的距离取代了汽车的使用。这项工作揭示了使用电动自行车的一系列优势以及需要解决的问题,包括购买成本、盗窃、对电池安全性的负面看法以及缺乏合适的电动货运自行车基础设施。该研究表明,目前在英国有一些未采用电动载货自行车的人群,对他们来说,电动载货自行车是一种现实而理想的出行方式,有可能减少汽车使用和相关排放,并可能对健康和家庭活动有好处。

Shared e-scooters are popular, but improperly parked e-scooters impede access for pedestrians. Policymakers need knowledge about the impact and limitations of parking measures to reduce clutter. This paper evaluates pilots that introduced dedicated e-scooter parking places in areas with free-floating parking. Parking racks were implemented in a borough in Oslo, while painted spaces were introduced in the city centres of Oslo and Trondheim. The parking measures were evaluated using video recordings, GPS-data and surveys. Results show that about two thirds of riders ending their trip in the vicinity of a parking measure park in or near the measure. The parking becomes more concentrated around the measures and there is a clear reduction in the share of e-scooters in the area that impede access for pedestrians. The large variations from site to site indicate that the exact placement of the parking measure is important. The effect of voluntary parking measures is greatest in the immediate vicinity and appears to fade away about 70 m from the measures. Non-riders experience parked e-scooter as an obstacle to a significantly greater extent than riders do, and there was no significant decrease in perceptions of e-scooters as an obstacle after a parking rack was placed. Overall, voluntary parking measures appear to improve parking behaviour in the immediate vicinity, but do not eliminate problematic parking.
共享电动滑板车很受欢迎,但停放不当的电动滑板车阻碍了行人的通行。政策制定者需要了解停车措施的影响和局限性,以减少混乱。本文对在自由浮动停车场引入电动滑板车专用停车位的试点进行了评价。在奥斯陆的一个自治市镇安装了停车架,而在奥斯陆和特隆赫姆的市中心引入了彩色空间。通过录像、gps数据和调查对停车措施进行了评估。结果显示,大约三分之二的乘客在停车措施附近停车或在该措施附近停车。停车场变得更加集中在这些措施周围,阻碍行人通行的电动滑板车的比例明显减少。不同地点之间的巨大差异表明停车措施的确切位置很重要。自愿停车措施的效果在邻近地区最大,并在措施实施70 m后逐渐消失。与骑车者相比,不骑车者将停放的电动滑板车视为障碍的程度要大得多,而且在放置停放架后,将电动滑板车视为障碍的感觉并没有显著下降。总的来说,自愿停车措施似乎改善了附近地区的停车行为,但并没有消除停车问题。

Introduction

Cognitive decline with aging is a population health issue. Cycling may help maintain cognitive function and prevent cognitive decline in older adulthood. We conducted a scoping review to summarize and identify gaps in the literature examining cycling for transportation and/or recreation and their association with cognition in middle-aged and older adults.

Methods

Nine bibliographic databases were searched (inception-March 2024) to identify all articles that reported on cycling for transportation, leisure outdoors, or cycling indoors along a virtual bike path, and any cognitive outcome among adults ≥ 45 years of age. We summarized article findings and associations narratively.

Results

Searching identified 5171 citations, and 23 articles were included examining apparently healthy and clinical populations. Cycling interventions included virtual cycling indoors (randomized controlled trials=10, quasi-experimental=5), cycling outdoors for recreation (quasi-experimental=3, cross-sectional=1), any reason (cohort=1, cross-sectional=1), or transportation (simulation modelling=2). The most frequently examined cognitive outcome was executive function (n = 15), followed by memory (n = 9) and, global cognition (n = 9). Most articles (70 %) reported a statistically significant positive association between cycling and a cognitive outcome. Identified literature gaps include, a lack of sex- and gender-based analyses; robust study designs exploring cycling outdoors including for transportation; and literature examining additive cognitive benefits of cycling over other physical activity and transportation modes.

Conclusion

Cycling may help maintain or improve cognitive health during aging. Further high-quality research is needed to examine outdoor and transport cycling across all cognitive outcomes, the additional benefits of cycling over other physical activity and transportation modes, and whether gender differences exist. Cycling may help maintain or improve cognitive health during aging.

老年认知能力下降是一个人口健康问题。骑自行车可能有助于维持认知功能,防止老年人的认知能力下降。我们进行了一项范围综述,以总结和确定文献中关于骑自行车作为交通和/或娱乐方式及其与中老年认知关系的空白。方法检索9个文献数据库(开始至2024年3月),以确定所有报道骑自行车作为交通工具、户外休闲或沿着虚拟自行车道在室内骑自行车的文章,以及≥ 45岁成年人的任何认知结果。我们以叙述性的方式总结了文章的发现和关联。结果检索得到5171条引用,其中23篇文章检查了明显健康的临床人群。骑行干预包括室内虚拟骑行(随机对照试验=10,准实验=5)、户外骑行娱乐(准实验=3,横断面=1)、任何原因(队列=1,横断面=1)或交通(模拟建模=2)。最常检查的认知结果是执行功能(n = 15),其次是记忆(n = 9)和整体认知(n = 9)。大多数文章(70 %)报道了骑车和认知结果之间有统计学意义的正相关。已确定的文献缺口包括:缺乏性别和基于性别的分析;稳健的研究设计探索户外骑自行车,包括交通;还有文献研究了骑自行车对认知的附加益处,而不是其他体育活动和交通方式。结论骑自行车有助于维持或改善老年人的认知健康。需要进一步的高质量研究来检查户外和交通自行车在所有认知结果中的作用,骑自行车相对于其他身体活动和交通方式的额外好处,以及性别差异是否存在。骑车可能有助于维持或改善老年人的认知健康。需要进一步的高质量研究来检查户外和交通自行车在所有认知结果中的作用,骑自行车相对于其他身体活动和交通方式的额外好处,以及性别差异是否存在。

Active mobility is increasingly recognised as the cornerstone of sustainable urban development. Providing suitable infrastructure for walking and cycling is essential for promoting active transport and achieving its associated environmental and health benefits. However, systematically evaluating the suitability of active mobility infrastructure remains a methodological challenge. This paper presents a multilayered conceptual framework designed to assist policymakers, practitioners, and researchers in assessing active mobility infrastructure by integrating Pedestrian and Bicycle Level of Service models with the principles of the 15 min city. The hierarchical framework organises six broad constructs, such as Facilities, Geometric Design, Built and Natural Environment, Amenities, Proximity and Accessibility, and Flow and Traffic Characteristics, under which 138 unique indicators are classified. A systematic review of 78 studies using the PRISMA protocol guided the development of this structure, revealing both commonly cited and underutilised indicators critical for infrastructure evaluation. The three-layered framework illustrates how pedestrian and cyclist experiences are shaped by the interplay between physical infrastructure, its surrounding environment, and functional performance. It enhances conceptual clarity, reduces redundancy and ambiguities caused by overlapping terminologies, and supports evaluation at both micro and macro scales. It introduces the "Golden Nuggets", i.e., the essential indicators for evaluating non-motorised infrastructure and highlights underused but important metrics.

人们日益认识到,主动出行是城市可持续发展的基石。为步行和骑自行车提供适当的基础设施对于促进主动交通和实现相关的环境和健康效益至关重要。然而,系统地评估主动移动基础设施的适用性仍然是一个方法上的挑战。本文提出了一个多层概念框架,旨在通过将步行和自行车服务水平模型与15分钟城市原则相结合,帮助政策制定者、从业者和研究人员评估主动移动基础设施。该分级框架组织了六个广泛的结构,如设施,几何设计,建筑和自然环境,便利设施,邻近和可达性,以及流量和交通特征,在138个独特的指标下分类。对使用PRISMA协议的78项研究的系统回顾指导了该结构的发展,揭示了对基础设施评估至关重要的常被引用和未充分利用的指标。这个三层框架说明了行人和骑自行车的人的体验是如何通过物理基础设施、周围环境和功能性能之间的相互作用而形成的。它增强了概念的清晰度,减少了由重叠术语引起的冗余和歧义,并支持微观和宏观尺度的评估。它介绍了“金块”,即评估非机动基础设施的基本指标,并强调了未充分利用但重要的指标。该框架还建议将基于路段的评估扩展到基于路由和网络的水平,推进当前的PLOS和BLOS模型。未来的研究应侧重于跨空间尺度的实证验证和指标加权方案的开发,以增强该框架作为实用、可扩展和可转移的评估工具的应用。

Shared micromobility (SMM), including bicycles, e-bikes, scooters, etc., is often cited as a solution to the first and especially the last mile problem of public transport (PT), yet when implemented, they often do not get adopted by a broader travelling public. As behavioural adaption is largely related to peoples’ attitudes and perceptions, we develop a behavioural framework based on the UTAUT2 framework to gain better understanding why individuals may (not) be willing to use SMM. Through an exploratory factor analysis (EFA) and a latent class cluster analysis (LCCA), we study the adoption potential of SMM and assess drivers and barriers as perceived by different user groups. Our findings uncover six user groups; Shared mobility positives, Car-oriented sharing neutrals, Older apprehensive sharers, Young eager adopters, (Shared) Mobility avoiders and Skilled sharing sceptics. The Young eager adopters and Shared mobility positives tend to be the most open to adopting SMM and able to do so. Older apprehensive sharers would like to, but find it difficult or dangerous to use, while Skilled sharing sceptics are capable and confident, but have limited intention of using it. Car-oriented sharing neutrals and (Shared) Mobility avoiders are most negative about SMM, finding it difficult to use and dangerous. Factors relating to technological savviness, ease-of-use, physical safety and societal perception seem to be the strongest adoption predictors. Younger, high-educated males are the group most likely and open to using SMM, while older individuals with lower incomes and a lower level of education tend to be the least likely.
共享微型交通(SMM),包括自行车、电动自行车、踏板车等,通常被认为是解决公共交通(PT)第一英里,特别是最后一英里问题的解决方案,然而,当实施时,它们通常不会被更广泛的出行公众所采用。由于行为适应在很大程度上与人们的态度和看法有关,我们基于UTAUT2框架开发了一个行为框架,以更好地理解个人可能(不)愿意使用SMM的原因。通过探索性因子分析(EFA)和潜在类聚类分析(LCCA),我们研究了SMM的采用潜力,并评估了不同用户群体感知的驱动因素和障碍。我们的发现揭示了六个用户群体;共享出行的积极者,以汽车为导向的共享中立者,年长的忧虑型共享者,年轻的渴望接受者,(共享)出行回避者和熟练的共享怀疑论者。年轻的积极采用者和共享出行的积极分子倾向于最开放地采用SMM,并且能够这样做。年长的担心分享者想要使用,但发现使用起来困难或危险,而熟练的分享怀疑论者有能力和信心,但使用它的意图有限。以汽车为导向的共享中立者和(共享)移动回避者对SMM最持负面态度,认为它难以使用且危险。与技术熟练度、易用性、人身安全和社会认知相关的因素似乎是最有力的采用预测因素。年轻、受过高等教育的男性是最有可能和最愿意使用SMM的群体,而收入较低、受教育程度较低的老年人往往最不可能使用SMM。

Reducing speed limits to create safer, lower-stress environments for cyclists is a widely proposed policy but often faces resistance due to concerns about increased travel times. This study evaluates these concerns by assessing Level of Traffic Stress (LTS) under existing speed limits (base scenario) and the effects of reducing residential street speed limits to 40 km/h and 30 km/h (alternative scenarios) on cycling LTS and car travel time.
LTS is a widely used measure of cycling stress, categorising road segments from LTS-1 (least stressful) to LTS-4 (most stressful). We assigned LTS values to all road segments in Greater Melbourne based on cycling infrastructure, road hierarchy, traffic volume, and speed limits from OpenStreetMap. Trips from a government travel survey were then routed through the network to estimate exposure to different LTS levels under base and alternative scenarios. Additionally, a mode choice model was developed to examine the impact of LTS exposure on cycling likelihood. Finally, an agent-based transport model was used to evaluate the impact of this intervention on car travel time.
Results showed significant reductions in high-LTS exposure with lower speed limits. Under the base case, 27.9% of routes were on LTS-1 roads, and at 30 km/h this increased to 63.3%. Mode choice model results confirmed a strong negative correlation between cycling likelihood and high-LTS exposure. Car travel time impacts were minimal, even for trips largely on residential streets the average was only one minute.
降低车速限制,为骑自行车的人创造更安全、压力更小的环境,是一项被广泛提出的政策,但由于担心会增加出行时间,这一政策经常遭到抵制。本研究通过评估现有限速(基本情景)下的交通压力水平(LTS),以及将住宅街道限速降低至40公里/小时和30公里/小时(替代情景)对骑行LTS和汽车旅行时间的影响,来评估这些担忧。LTS是一种广泛使用的骑行压力测量方法,它将道路分段从LTS-1(压力最小)到LTS-4(压力最大)分类。我们根据OpenStreetMap的自行车基础设施、道路等级、交通量和速度限制,为大墨尔本的所有路段分配了LTS值。然后,从政府旅行调查中得出的行程通过网络进行路由,以估计在基本和替代方案下暴露于不同LTS水平的情况。此外,我们还建立了一种模式选择模型来检验LTS暴露对循环可能性的影响。最后,利用一个基于agent的交通模型来评估这种干预对汽车出行时间的影响。结果显示,较低的速度限制显著减少了高lts暴露。在基本情况下,27.9%的路线在LTS-1道路上,而在30公里/小时的情况下,这一比例增加到63.3%。模式选择模型结果证实了循环可能性与高lts暴露之间的强烈负相关。汽车出行时间的影响很小,即使是在居民区的街道上,平均也只有一分钟。

The global rise of e-scooters as a novel form of micromobility has reshaped urban transportation. Positioned as a sustainable mobility solution, transportation scholars underline that e-scooters have the potential to replace short car trips, reduce traffic congestion and carbon emissions, and increase energy efficiency of transportation systems. While existing literature has explored e-scooter adoption and trip characteristics extensively, there remains a research gap regarding the classification of e-scooter users. This paper attempts to overcome this deficiency by employing a latent class cluster analysis to classify e-scooter users based on their trip frequency, motivation, and purpose. Data used for the analysis were collected from e-scooter users in Washington, DC and Portland, OR in the United States. The results reveal two distinct classes of e-scooter users: ‘Joyriders’ and ‘Busyriders’. Joyriders tend to be young, female and belong to higher-income and vehicle-affluent households. They use e-scooters for leisure or tourism purposes, valuing pleasure and time savings. Busyriders are predominantly males aged 18–54 from vehicle-deficient households spanning diverse income groups and use e-scooters weekly for commuting, errands, and shopping purposes, prioritizing utilitarian and environmental benefits. The findings of this study can inform policymakers in developing effective e-scooter promotion policies, tailored to the preferences and needs of different user groups. The policy implications from this study can contribute towards the incorporation of e-scooters as a sustainable and efficient travel alternative into urban transportation.
电动滑板车作为一种新型微型交通工具在全球兴起,重塑了城市交通。交通学者强调,作为一种可持续的交通解决方案,电动滑板车有可能取代短途汽车出行,减少交通拥堵和碳排放,并提高交通系统的能源效率。虽然现有文献对电动滑板车的使用和出行特征进行了广泛的探讨,但对电动滑板车用户的分类研究仍然存在空白。本文试图通过使用潜在类聚类分析来根据他们的出行频率,动机和目的对电动滑板车用户进行分类,从而克服这一缺陷。用于分析的数据是从美国华盛顿特区和波特兰的电动滑板车用户中收集的。研究结果显示,电动滑板车用户分为两类:“兜风者”和“忙碌者”。开车兜风的人往往是年轻的女性,属于收入较高、拥有大量车辆的家庭。他们将电动滑板车用于休闲或旅游目的,重视乐趣和节省时间。乘坐电动滑板车的人主要是年龄在18-54岁之间的男性,他们来自不同收入群体的无车家庭,每周使用电动滑板车上下班、办事和购物,优先考虑实用性和环境效益。本研究的结果可以为政策制定者制定有效的电动滑板车推广政策提供参考,以适应不同用户群体的偏好和需求。这项研究的政策意义可以有助于将电动滑板车作为一种可持续和高效的出行选择纳入城市交通。

Understanding free riding behavior—where bicyclists are unconstrained by other road users or traffic control measures—is essential for planning efficient and appealing bicycle traffic systems. Bicyclist behavior is shaped by a combination of environmental conditions and individual preferences. This study examines free riding behavior, and identifies correlations with individual characteristics and contextual features such as infrastructure design (slopes and curves) and wind speed. We introduce a method using instrumented bicycles in a semi-controlled experiment to collect data describing the speed, power output, and heart rate of commuting bicyclists. Participants in two study populations (28 in Sweden and 29 in Germany) ride their bicycles equipped with sensors along designated routes during off-peak demand periods, enabling comparative analysis of different trip features. Results highlight significant inter- and intrapersonal variations in speed and power output along a trip. Approximately 80 percent of the variation in free riding speed and power output over a trip, and over both populations of bicyclists, is explained by gender, individual preferences, topography, curvature, crossing intersections, and wind speeds. Headwinds and uphills generally reduce speeds but bicyclists increase power output to partially offset these effects. Downhills lead to high speed variation and distinct tactical behaviors, such as braking, coasting, and accelerating. These findings underscore the complexity of bicycling behavior and quantify how bicyclists adapt to varying features of the trip.
了解免费骑行行为——骑自行车的人不受其他道路使用者或交通管制措施的约束——对于规划高效和有吸引力的自行车交通系统至关重要。骑自行车的人的行为是由环境条件和个人偏好共同决定的。这项研究考察了搭便车行为,并确定了个人特征和环境特征(如基础设施设计(斜坡和曲线)和风速)之间的相关性。在半控制实验中,我们介绍了一种使用仪表自行车来收集通勤骑自行车者的速度、功率输出和心率数据的方法。两个研究群体的参与者(瑞典28人,德国29人)在非高峰时段沿着指定路线骑装有传感器的自行车,以便对不同的出行特征进行比较分析。结果强调了在旅途中速度和功率输出的显著的人与人之间和人与人之间的差异。大约80%的免费骑行速度和功率输出的变化,在一次旅行中,在两个骑自行车的人群中,可以用性别、个人偏好、地形、曲率、十字路口和风速来解释。逆风和上坡通常会降低速度,但骑自行车的人会增加功率输出来部分抵消这些影响。下坡导致高速变化和独特的战术行为,如制动,滑行和加速。这些发现强调了骑自行车行为的复杂性,并量化了骑自行车者如何适应旅行的不同特征。
