This study aimed to estimate the impact of implementing a public bicycle share program (PBSP) on the likelihood of self-reported collisions and near misses between cyclists and motor vehicles among cyclists living in Montreal.
A repeated cross sectional design was used. Surveys were conducted at the launch of the PBSP, at the end of the first and second seasons of implementation. Logistic regression estimated changes in the likelihood of reporting collisions or near misses.
There was no evidence of a change in likelihood of reporting a collision or near miss after implementing the PBSP. PBSP users were not at a greater risk of reporting a collision (OR=1.53, 95% CI: 0.77-3.02) or near miss (OR=1.37, 95% CI: 0.94-1.98), although confidence intervals were wide. The number of days of cycling per week was associated with collisions (OR=1.27, 95% CI: 1.17-1.39) and near misses (OR=1.34, 95% CI: 1.26-1.42).
There was no evidence of a change in the likelihood of reporting collisions or near misses in Montreal between the implementation of the PBSP and the end of the second season. Time spent cycling was associated with reporting a collision or near miss.
本研究旨在评估在蒙特利尔推行公共自行车共享计划（PBSP）对自行车骑行者与机动车发生自报告碰撞和险些碰撞的可能性的影响。
采用重复横截面设计。在 PBSP 启动时、实施的第一个和第二个季节结束时进行了调查。使用逻辑回归估计报告碰撞或险些碰撞的可能性的变化。
在实施 PBSP 后，报告碰撞或险些碰撞的可能性没有变化的证据。PBSP 用户报告碰撞（OR=1.53，95%CI：0.77-3.02）或险些碰撞（OR=1.37，95%CI：0.94-1.98）的风险没有增加，尽管置信区间较宽。每周骑自行车的天数与碰撞（OR=1.27，95%CI：1.17-1.39）和险些碰撞（OR=1.34，95%CI：1.26-1.42）有关。
在 PBSP 实施和第二个季节结束之间，在蒙特利尔报告碰撞或险些碰撞的可能性没有变化的证据。骑自行车的时间与报告碰撞或险些碰撞有关。
