Over the past 12 months, Metro has worked with other transit providers, the Washington State Department of Transportation, cities, and the public to explore three conceptual service networks and the capital investments necessary to support them. The networks were developed in close coordination with Sound Transit to ensure that Metro’s future bus service is integrated with planned expansions of the Link light rail and Sounder commuter rail systems as well as modifications to regional express bus service. Metro also evaluated current trends influencing transportation, such as car and ride sharing, as well as the economic benefits of transit to King County. This report summarizes the process used to develop and analyze the three conceptual service networks.
