Abstract:Collaborative research between the University of Maryland’s National University Transportation Center (UTC) and George Mason University, a Tier 1 UTC consortium member, has resulted in a project that examines the human and system-wide impacts of the Washington Metro SafeTrack – a series of 15 major track maintenance projects that will partially shut down or significantly reduce Metro rail transit services between summer 2016 and spring 2017. Part of the research was subsequently funded by the National Science Foundation, demonstrating how UTC seed money can help researchers leverage additional funding resources to extend the value and impact of their work. The research team is collecting a unique before-and-after travel behavior adjustment dataset by integrating mail/web-based surveys, smartphone-based surveys, vehicle probe data, transit ridership dynamics, bike share usage, and bike and pedestrian counts. The objective is to improve understanding of human behavioral responses, decision-making by travelers, and system re-equilibration after such transit system disruptions through modeling and data analysis. In addition, the multidisciplinary research team applies an integrated agent-based travel behavior (SILK) and dynamic traffic simulation (DTALite) model system to predict the regional and local traffic impact of each of the 15 SafeTrack surges, which helps travelers plan ahead.
