Abstract During subway disruptions, commuters are often left stranded while they wait for bus bridging services. Some are able to change their mode of transport midway through their trip, often by requesting a ride-hailing service like Uber or Lyft if they are affordable. Many agencies use in-service buses to provide bus bridging services during subway disruptions, leading to reduced levels of service for other bus riders. Bus bridging policies and the affordability of ride-hailing raise questions regarding the equitable distribution of transit capacity during subway disruptions. After analyzing 78 major subway disruptions in Toronto, we found that bus routes serving disadvantaged populations were more likely to be negatively impacted by diversions for subway disruptions, than routes operating in more affluent areas of the city. We also found that ride-hailing demand increased during subway disruptions, but not in the more disadvantaged neighbourhoods. The research points to inequalities in how transit riders are impacted by subway disruptions, and further identifies how ride-hailing actually serves to reinforce these inequalities, rather than ameliorate them.

关于公交车桥接和乘车响应对计划外地铁中断的社会公平视角

摘要 在地铁中断期间，通勤者在等待公交车桥接服务时经常被困。有些人能够在旅途中途改变他们的交通方式，通常是在价格合理的情况下要求使用 Uber 或 Lyft 等叫车服务。许多机构使用在役巴士在地铁中断期间提供巴士桥接服务，导致其他巴士乘客的服务水平降低。公交桥接政策和网约车的可负担性引发了有关地铁中断期间公交容量公平分配的问题。在分析了多伦多的 78 次主要地铁中断后，我们发现，与在城市较富裕地区运营的路线相比，为弱势群体服务的公交路线更有可能受到因地铁中断而改道的负面影响。我们还发现，在地铁中断期间，叫车需求增加，但在较贫困的社区则不然。该研究指出了地铁中断对公交乘客的影响存在不平等，并进一步确定了叫车服务实际上是如何加强而不是改善这些不平等的。
