Abstract

Knowledge about how weather conditions affect travel behavior in different user groups and contexts is relevant for planners and policymakers to facilitate sustainable transportation systems. We aimed to assess the influence of day-to-day weather on cycling for transportation among parents of young children with access to different bike types (e-bike vs non e-bike) in a natural study setting over nine months. We hypothesized less impact of weather variability on cycling when using an e-bike compared with a non e-bike. A randomized, controlled trial was conducted in Southern Norway. The intervention group (n = 18) was in random order equipped with an e-bike with trailer for child transportation (n = 6), a cargo (longtail) bike (n = 6) and a traditional bike with trailer (n = 6), each for three months. These 18 participants reported cycling on 832 out of 3276 person-days (25%). We used dynamic structural equation modeling for intensive longitudinal data to examine the relations between daily weather conditions, bike type (e-bike vs traditional bike), and cycling (dichotomized daily at yes or no). Air temperature (positively) and wind speed (negatively) were both credible predictors of cycling, whereas the other predictors (precipitation in the morning (yes or no) and presence of snow (yes or no) were not. We added interaction terms between bike type and weather conditions, but none of the interaction terms had a credible effect on cycling. Thus, the relations between weather conditions and cycling were not moderated by bike type among parents of young children.

天气条件对参加CARTOBIKE随机对照试验的幼儿父母每天骑不同类型自行车的影响

摘要了解天气条件如何影响不同用户群体和环境中的出行行为，对于规划者和决策者促进可持续交通系统具有重要意义。我们的目的是在一项为期九个月的自然研究中，评估日常天气对使用不同自行车类型（电动自行车与非电动自行车）的幼儿父母骑自行车出行的影响。我们假设，与非电动自行车相比，使用电动自行车时天气变化对骑自行车的影响较小。在挪威南部进行了一项随机对照试验。干预组（n = 18）按随机顺序配备了一辆带拖车的电动自行车用于儿童运输（n = 6），一辆货运（长尾）自行车 = 6）和一辆带拖车的传统自行车（n = 6），每个为期三个月。这18名参与者报告说，3276人日中有832人（25%）骑自行车。我们使用动态结构方程模型对密集的纵向数据进行建模，以检查日常天气条件、自行车类型（电动自行车与传统自行车）和自行车（每天按是或否进行二分）之间的关系。气温（正）和风速（负）都是自行车运动的可靠预测因素，而其他预测因素（早上的降水量（是或否）和是否有雪（是或没有））则不然。我们增加了自行车类型和天气条件之间的相互作用项，但没有一个相互作用项对自行车有可信的影响。因此，在幼儿父母中，天气条件与骑自行车之间的关系不受自行车类型的调节。

期刊介绍： The International Journal of Sustainable Transportation provides a discussion forum for the exchange of new and innovative ideas on sustainable transportation research in the context of environmental, economical, social, and engineering aspects, as well as current and future interactions of transportation systems and other urban subsystems. The scope includes the examination of overall sustainability of any transportation system, including its infrastructure, vehicle, operation, and maintenance; the integration of social science disciplines, engineering, and information technology with transportation; the understanding of the comparative aspects of different transportation systems from a global perspective; qualitative and quantitative transportation studies; and case studies, surveys, and expository papers in an international or local context. Equal emphasis is placed on the problems of sustainable transportation that are associated with passenger and freight transportation modes in both industrialized and non-industrialized areas. All submitted manuscripts are subject to initial evaluation by the Editors and, if found suitable for further consideration, to peer review by independent, anonymous expert reviewers. All peer review is single-blind. Submissions are made online via ScholarOne Manuscripts.
