Central Puget Sound Interstate 5 - Park and rides
On this page:
Measures of park and rides along the I-5 corridor in the central Puget Sound region.
Park and ride lot utilization
Park and ride lots provide locations for commuters to meet carpools and vanpools and catch buses if transit services are not available near their residences. WSDOT monitors the usage of park and ride lots owned or managed by public agencies, as well as private lots. See WSDOT's How to calculate park and ride lot utilization (pdf 5.9 mb).
Park and ride lots serve a wide variety of commuters, including carpoolers, vanpoolers, transit riders, commuter rail passengers, bicyclists and pedestrians. Park and ride locations are essential for transit riders and carpoolers, and must have high utilization rates to be considered successful. Targeted outreach efforts from transit agencies as well as employer Commute Trip Reduction initiatives help address highway capacity needs in the central Puget Sound region.
