Trip pool is a flexible rideshare program

Share The Ride. Connect To Transit. Get Reserved Parking!

TripPool is a King County Metro pilot program providing on-demand rideshare options to connect riders to transit in select areas. Metro-provided commuter vans make one round-trip each work day to a park & ride or transit center. Volunteer drivers pick-up and drop-off registered riders along the way. TripPool trips are coordinated by riders and drivers on their smartphone through the free mobile app, iCarpool.
