The "Citi Bike" bike share program in New York City is the largest bike share program in the USA. We ask whether expanding this program to lower-income communities is cost-effective means of encouraging exercise and reducing pollution in New York City. We built a stochastic Markov model to evaluate the cost-effectiveness of the Citi Bike expansion program, an effort to extend bike share to areas with higher costs and risks over a 10-year time horizon. We used one-way sensitivity analyses and Monte Carlo simulation to test the model uncertainty. The incremental cost-effectiveness ratio of the Citi Bike expansion program relative to the current program (status quo) was $7869/quality-adjusted life year gained. The Citi Bike expansion program in New York City offers good value relative to most health interventions.
纽约市的“Citi Bike”自行车共享计划是美国最大的自行车共享计划。我们想知道将该计划扩展到低收入社区是否是一种鼓励在纽约市进行锻炼和减少污染的具有成本效益的手段。我们建立了一个随机马尔可夫模型来评估 Citi Bike 扩展计划的成本效益，该计划旨在将自行车共享服务扩展到成本更高、风险更大的地区，时间跨度为 10 年。我们使用单因素敏感性分析和蒙特卡罗模拟来测试模型的不确定性。Citi Bike 扩展计划相对于当前计划（现状）的增量成本效益比为每获得 1 个质量调整生命年增加 7869 美元。纽约市的 Citi Bike 扩展计划相对于大多数健康干预措施具有良好的价值。
