Introduction

Bicycling is a type of physical activity associated with positive health outcomes, but many barriers exist to regular bicycling for recreation and transportation. The objective of this study was to describe self-reported barriers to bicycling overall, and by bicycling domain, among a national sample of persons aged 16 and above that reported bicycling outside in the past week.

Methods

This analysis, conducted in 2019, utilized data from the United States (US) Department of Transportation's 2017 National Household Travel Survey (NHTS). Weighted point estimates and 95% confidence intervals were calculated for reported barriers to bicycling by category of bicyclist: exercise-exclusive, multi-use, and commuter.

Results

The final analytic sample was 18,189, representing approximately 7% of the US population (N = 20,911,680). Barriers that prevented bicycling more was reported by 37.9% of the US population of adult bicyclists (95% CI 37.2, 38.6). Barriers related to safety were more commonly reported (31.9% of total bicyclists), compared to barriers related to infrastructure (22.1% of total bicyclists). Safety-related barriers were more commonly reported among multi-use bicyclist (33.7% vs. 30.9% of exercise-exclusive). Commuter bicyclists reported infrastructure barriers the least (13.9% vs. 22.7% of exercise-exclusive). The most commonly reported single barrier to bicycling more, regardless of bicycling category, was heavy traffic (10.3% of total bicyclists), followed by no nearby paths or trails (7.6% of total bicyclists). Overall, distribution of individual barriers was similar across categories of bicyclists: exercise-exclusive, multi-use, and commuter.

Conclusions

Heavy traffic and lack of separated paths or trails were the most frequently identified barriers to bicycling more. Communities wishing to promote bicycling for transportation, recreation, or both should consider how traffic reduction strategies and changes in the built environment could make bicycling safer and more accessible.

美国成年人通勤和骑自行车运动的感知障碍：2017年全国家庭旅行调查

介绍

骑自行车是一种与积极健康成果相关的体育活动，但是定期骑自行车进行娱乐和运输存在许多障碍。这项研究的目的是在过去一周内报告在国外骑自行车的16岁及以上人群的全国样本中，通过自行车领域来描述自我报告的总体骑自行车障碍。

方法

该分析于2019年进行，利用了美国运输部2017年全国家庭旅行调查（NHTS）的数据。根据骑自行车者的类别：运动除外，多用途和通勤者，对报告的骑自行车障碍进行加权得分估计和95％置信区间。

结果

最终的分析样本为18,189，约占美国人口的7％（N = 20,911,680）。据报告，美国成年骑自行车者中有37.9％的人阻碍了骑车活动的发展（95％CI 37.2、38.6）。与安全相关的障碍（占自行车总人数的31.9％）比与基础设施相关的障碍（占自行车总人数的22.1％）更为普遍。与安全相关的障碍在多用途自行车骑行者中更为普遍（33.7％对30.9％的运动除外）。通勤者骑自行车的人报告说，基础设施障碍最少（分别为13.9％和22.7％）。不论骑行类别如何，最常报告的骑行障碍更多的单一障碍是交通繁忙（占骑自行车者总数的10.3％），其次是附近没有道路或小径（占骑自行车者总数的7.6％）。总体，

结论

交通拥挤，缺乏分隔的路径或小径是骑自行车较多的最常见障碍。希望促进骑行交通，娱乐或两者兼而有之的社区应考虑减少交通流量的策略和建筑环境的变化如何使骑行更加安全和便捷。
