Cycling contributes to physical activity and health. Public bicycle share programs (PBSPs) increase population access to bicycles by deploying bicycles at docking stations throughout a city. Minimal research has systematically examined the prevalence and correlates of PBSP use.
To determine the prevalence and correlates of use of a new public bicycle share program called BIXI (name merges the word BIcycle and taXI) implemented in May 2009 in Montreal, Canada.
A total of 2502 adults were recruited to a telephone survey in autumn 2009 via random-digit dialing according to a stratified random sampling design. The prevalence of BIXI bicycle use was estimated. Multivariate logistic regression allowed for identification of correlates of use. Data analysis was conducted in spring and summer 2010.
The unweighted mean age of respondents was 47.4 (SD=16.8) years and 61.4% were female. The weighted prevalence for use of BIXI bicycles at least once was 8.2%. Significant correlates of BIXI bicycle use were having a BIXI docking station within 250 m of home, being aged 18-24 years, being university educated, being on work leave, and using cycling as the primary mode of transportation to work.
A newly implemented public bicycle share program attracts a substantial fraction of the population and is more likely to attract younger and more educated people who currently use cycling as a primary transportation mode.
骑自行车有助于身体活动和健康。公共自行车共享计划（PBSP）通过在城市各处的停靠站部署自行车，增加了人们对自行车的使用。很少有研究系统地研究了 PBSP 使用的流行率和相关因素。
确定 2009 年 5 月在加拿大蒙特利尔实施的名为 BIXI（BIcycle 和 taXI 的组合词）的新公共自行车共享计划的使用流行率和相关因素。
2009 年秋季，通过随机数字拨号，根据分层随机抽样设计，共招募了 2502 名成年人参加电话调查。估计了 BIXI 自行车的使用流行率。多变量逻辑回归允许确定使用的相关因素。数据分析于 2010 年春季和夏季进行。
受访者的未加权平均年龄为 47.4（SD=16.8）岁，61.4%为女性。至少使用过一次 BIXI 自行车的加权流行率为 8.2%。BIXI 自行车使用的显著相关因素包括家庭附近 250 米范围内有 BIXI 停靠站、年龄在 18-24 岁之间、受过大学教育、正在休假以及将骑自行车作为主要的上班交通方式。
新实施的公共自行车共享计划吸引了相当一部分人口，并且更有可能吸引目前将骑自行车作为主要交通方式的年轻人和受过更高教育的人。
