We examined associations between residential exposure to BIXI (BIcycle-taXI)-a public bicycle share program implemented in Montreal, Quebec, in 2009, which increases accessibility to cycling by making available 5050 bicycles at 405 bicycle docking stations-and likelihood of cycling (BIXI and non-BIXI) in Montreal over the first 2 years of implementation.
Three population-based samples of adults participated in telephone surveys. Data collection occurred at the launch of the program (spring 2009), and at the end of the first (fall 2009) and second (fall 2010) seasons of implementation. Difference in differences models assessed whether greater cycling was observed for those exposed to BIXI compared with those not exposed at each time point.
We observed a greater likelihood of cycling for those exposed to the public bicycle share program after the second season of implementation (odds ratio = 2.86; 95% confidence interval = 1.85, 4.42) after we controlled for weather, built environment, and individual variables.
The implementation of a public bicycle share program can lead to greater likelihood of cycling among persons living in areas where bicycles are made available.
我们调查了 2009 年在魁北克省蒙特利尔市实施的 BIcycle-taXI（BIXI）公共自行车共享计划（在 405 个自行车停靠站提供 5050 辆自行车，以增加自行车出行的便利性）对居民暴露程度与头 2 年实施期间骑自行车（BIXI 和非 BIXI）的可能性之间的关联。
三个基于人群的成年人样本参加了电话调查。数据收集在该计划启动时（2009 年春季）以及实施的第一个（2009 年秋季）和第二个（2010 年秋季）季节结束时进行。差异中的差异模型评估了与未暴露于 BIXI 的人相比，在每个时间点暴露于 BIXI 的人是否观察到更多的骑自行车行为。
在控制了天气、建筑环境和个体变量后，我们发现，在实施第二个季节后，暴露于公共自行车共享计划的人骑自行车的可能性更大（优势比=2.86；95%置信区间=1.85，4.42）。
公共自行车共享计划的实施可以使生活在提供自行车的地区的人们更有可能骑自行车。
