Abstract:To improve bus travel times and reliability, some transit bus agencies have turned to the implementation of designated bus lanes (DBLs). Designated bus lanes are those restricted to buses either permanently or during certain hours of the day. DBLs allow buses to bypass traffic congestion and avoid vehicular conflicts in mixed travel lanes, which helps improve bus service reliability. The District Department of Transportation (DDOT) proposed a dedicated bus lane pilot during the summer of 2019 on the H Street and I Street (NW) corridors in downtown DC. This study evaluated the impacts of DBLs on the general traffic flow at signalized intersections in Washington, DC following the installation.
