Abstract

The majority of Australian adolescents are insufficiently active and becoming car dependent. Replacing short passive travel (i.e. car, public transport) with active travel could be an important potential strategy to increase physical activity. This paper aims to characterize adolescents’ travel patterns to various destinations, identify passive trips that could be feasibly replaced by active travel, and the characteristics associated with those trips. Analyses were based on 2,192 Victorian secondary school students aged 12-17 years with 24-h travel diary data in the Victorian Integrated Survey of Travel Activity 2012 − 2016. Feasible distance thresholds for walking and cycling were determined at the 80^th percentile of distances of reported walking and cycling trips in the sample. Comparison tests were conducted to assess whether travel patterns differed by sociodemographic characteristics. Multilevel logistic regression analyses identified characteristics of individuals that could replace passive trips with active travel, and characteristics of passive trips that could be replaced by active travel. About 11% of adolescents could feasibly replace at least one of their short passive trips with walking and 48% could feasibly replace at least one of their short passive trips with cycling. Of all the passive trips recorded, about 8% could be replaced with walking and 44% could be replaced with cycling. Trips that commenced within daylight hours, and trips made for shopping and social reasons had higher odds of being replaceable by active travel. The sizable proportion of replaceable passive trips within the cyclable threshold calls for greater emphasis on encouraging cycling.

摘要

大多数澳大利亚青少年活动不足并变得依赖汽车。用主动出行代替短途被动出行（即汽车、公共交通）可能是增加身体活动的重要潜在策略。本文旨在描述青少年前往不同目的地的旅行模式，确定可以被主动旅行替代的被动旅行，以及与这些旅行相关的特征。分析是基于在旅游活动2012年维多利亚综合考察年龄在12-17岁与24小时的旅行日记数据2192名维多利亚女王时代的中学生-步行和骑自行车2016可行距离阈值均在80确定的^次样本中报告的步行和骑自行车的距离的百分位数。进行了比较测试以评估出行模式是否因社会人口学特征而有所不同。多级逻辑回归分析确定了可以用主动旅行代替被动旅行的个人特征，以及可以用主动旅行代替的被动旅行的特征。大约 11% 的青少年可以用步行代替至少一次短途被动旅行，48% 可以用骑自行车代替至少一次短途被动旅行。在记录的所有被动出行中，大约 8% 可以用步行代替，44% 可以用骑自行车代替。在白天开始的旅行以及出于购物和社交原因的旅行被主动旅行取代的可能性更高。
