Introduction

While bikeshare programs represent a promising platform for promoting physical activity and health, critics are concerned about their equity. In 2018, Greater Boston launched a low-income bikeshare membership program and expanded the number of available stations. This study examines: 1) changes in equity of station access and 2) changes in equity of bikeshare use as a result of the equity initiative.

Methods

We used publicly available trip history data to identify stations and trips during the pre-intervention (July 2013–December 2017) and intervention (January 2018–July 2019) periods. Using five transit and environmental justice indicators, we categorized census block groups by bikeshare need, then examined the number of block groups with full access to a station before and during the intervention. Logistic regression was used to evaluate the change in probability of a trip starting or ending in a high need block group during the intervention period.

Results

Following the implementation of Boston's equity initiative, bikeshare access and use increased across the city, although gains were smallest for communities most in need of access to alternative transportation options.

Conclusions

Boston's bikeshare system is an important public health and physical activity promotion opportunity. However, further improvements are needed to promote equity in access and use.

在大波士顿实施符合收入资格的会员计划和系统扩展后，自行车共享访问权和使用权的权益变化

介绍

共享单车计划是促进身体活动和健康的有前途的平台，但批评者对其公平性表示关注。2018年，大波士顿地区启动了低收入自行车共享会员计划，并扩大了可用车站的数量。这项研究考察了：1）股权倡议的结果，车站出入口的公平性变化和2）共享单车使用的公平性变化。

方法

我们使用公开的出行历史数据来识别干预前（2013年7月至2017年12月）和干预（2018年1月至2019年7月）期间的车站和出行。我们使用五个交通和环境司法指标，按自行车共享需求对人口普查街区组进行了分类，然后在干预之前和干预期间检查了可以完全进入车站的街区组的数量。Logistic回归用于评估干预期间在高需求障碍人群中旅程开始或结束的可能性的变化。

结果

实施波士顿的股权计划后，全市自行车共享的使用和使用量有所增加，尽管对于最需要替代交通​​方式的社区而言，收益增幅最小。

结论

波士顿的单车共享系统是重要的公共健康和体育锻炼机会。但是，需要进一步改善以促进获取和使用方面的公平。
