Foursquare ITP completed a service evaluation study of the Washington Metropolitan Area Transit Authority’s (WMATA) Metrobus 17 and 18 Lines. The study represented a comprehensive review of the transit service provided by the eight variations that comprise the 17 Line and the eight variations of the 18 Line, as well as the transportation setting in which these services operate. Our team executed a transit services assesment, performed a traffic operations assessment, and received input through our public outreach process through both online surveys and public events. We gave recommendations that provided insight on how WMATA could continue to provide effective service through the project corridors in a more efficient manner by decreasing total trip time and increasing service speed.
