TripPool is a King County Metro pilot program that encourages commuters to share the ride to local park & rides, helping to cut congestion, improve air quality in neighborhoods and make the most out of limited parking.

Metro offers vans to volunteer drivers willing to use an online app to match with and pick-up fellow commuters along the way to catch transit. The van remains in a reserved space at the park & ride during the day and the driver offers up a similar shared ride for the afternoon commute. Drivers and riders connect via a free online app.

TripPool Fast Facts

Reliable vans

The vehicles we provide include gas, insurance, and maintenance along with reserved parking and Guaranteed Ride Home (PDF).

Flexible routes

You use the iCarpool app to choose the listed stop that works best for you. TripPool drivers have the flexibility to make route adjustments.


With no monthly commitment, trip booking and fare payment is handled through the iCarpool mobile app when you need a trip.

Great value

  • Your trip is free when you're the driver.
  • You pay for trips using iCarpool 'ride credits'—only $1.50 for first five miles.
  • When you link your iCarpool and accounts you're reimbursed for charges above $2.75 (one-zone peak). Also, if you’re an ORCA monthly pass holder, provide your ORCA number and you'll be reimbursed 100% (essentially a free trip—just think of it as a pre-transfer).

TripPool riders and drivers are wanted in Bothell-Woodinville (Bothell P&R), Auburn (Auburn Sounder station) and Kenmore-Kirkland (Kingsgate and Kenmore P&Rs).
