Logan Airport Ground Access and Trip Reduction Strategy Study

Massachusetts Port Authority (Massport)

With more people flying than ever before, many airports now face growing air passenger volumes alongside changes in ground access options, namely the popularity of ride-hailing apps. These changes have led to congested curb space and roads as well as shifts in opportunities to collect ground transportation revenue. To address this, the Massachusetts Port Authority (Massport) sought policies that would balance growing passenger volumes with desired reductions in the use of private vehicle access modes. In response to these goals and associated Massachusetts regulation, Massport conducted a series of studies to examine the impact of potential policies on high-occupancy vehicle (HOV) use and how that affects airport congestion, airport revenues, surrounding communities, and the environment.

RSG worked closely with Massport to develop the studies’ comprehensive analytic framework to evaluate various policies—including changes in services, pricing, and operations—to improve Logan’s ground access. As part of this work spanning several years and tasks, RSG developed the Mode Choice Model and Simulator (MCMS) tool, which used data collected by RSG as part of a stated preference air passenger survey. With the MCMS, Massport can predict changes in ground access mode share for each set of policy changes. RSG’s work helped Massport plan for Logan’s current and future ground access needs by identifying achievable and impactful policy initiatives.
