An Employer Shared Transit Stop (ESTS) pilot was introduced in April, 2017 by the Seattle Department of Transportation (SDOT) and King County Metro (KCM). Eleven bus stops within the City of Seattle were identified for stop-sharing with private shuttles that serve employees of and are operated by Microsoft and Seattle Children’s Hospital, respectively. This study utilizes real-time transit performance data that was generated by KCM, then collected and aggregated by the company Swiftly to assess the impacts of the ESTS program on bus transit reliability. Data analyses based on visualization tools on the Swiftly Insights platform of route-level schedule adherence as well as fixed panel regressions at the mean and at the 0.90 and 0.95 quantile of stop-level schedule adherence are considered. On average, bus transit reliability has not been affected by the ESTS pilot program. Statistically significant results indicating a potential delay in bus arrival times as a result of ESTS stop-sharing were found at only one of the nine stops considered in the study. An increase in participating companies and stops is recommended.
