对北方社区的一组工作成年人进行了研究，以评估天气对骑自行车上下班的影响。参与者上下班至少2英里，每年骑自行车上下班两次以上。2009年和2010年记录了四个7天的运输模式（每个季节一个采样期）。模式、个人特征和通勤时间与特定地点和时间的天气条件以及通勤日的日照时间有关。分析集中在季节，天气和其他因素的影响，以开发骑自行车通勤的二元模型。早晨气温每升高1°F，骑自行车上下班的可能性增加3%，风速每增加1英里/小时，骑自行车上下班的可能性减少5%。在没有早晨降水的日子里，骑自行车上班的可能性增加了一倍多。数小时的日光没有明显的影响，尽管研究参与者在基线调查中将其列为障碍。上班距离对骑自行车通勤的可能性产生负面影响。男性在某一天骑车上下班的可能性几乎是女性的两倍。针对男性和女性的单独模型表明，这些群体对不利天气条件的反应相似，尽管由于样本量较小，女性中的一些影响不太明显。相当一部分参与者全年在各种天气条件下骑自行车上班，这一结果表明，北方气候可能不一定排除全年骑自行车通勤。多模式通勤在样本中很普遍：在参与者报告骑自行车上班的20%的日子里，他们报告通过另一种方式回家。帮助骑自行车的人学会安全地处理寒冷和黑暗的条件和促进多式联运自行车通勤可能会促进更广泛地使用自行车通勤和延长北方自行车通勤季节。
Research with a panel of working adults in northern communities was conducted to assess the impact of weather on commuting to work by bicycle. Participants commuted at least 2 mi each way and commuted by bike more than twice annually. Transportation mode was recorded for four 7-day periods in 2009 and 2010 (one sampling period per season). Mode, personal characteristics, and commute length were linked to location- and time-specific weather conditions and to daylight hours on commuting days. Analyses focused on the effects of season, weather, and other factors to develop binary models for commuting by bicycle. The likelihood of bike commuting increased 3% with every 1°F increase in morning temperature and decreased by 5% with a 1 mph increase in wind speed. Likelihood of biking to work was more than double on days with no morning precipitation. Hours of daylight had no discernible effect, although study participants cited this as a barrier in the baseline survey. Distance to work negatively affected the likelihood of bike commuting. Men were nearly twice as likely to bike commute on a given day as were women. Separate models for men and women suggested that these groups responded similarly to adverse weather conditions, although some effects were less pronounced among women because of a smaller sample size. An appreciable portion of participants biked to work throughout the year in a variety of weather conditions, a result that suggested that a northern climate might not necessarily preclude year-round bike commuting. Multimodal commuting was prevalent in the sample: on 20% of the days that participants reported biking to work, they reported returning home by another mode. Helping cyclists learn to deal safely with cold and dark conditions and facilitation of multimodal bicycle commuting may promote wider use of bicycle commuting and extend the northern bicycle commute season.
