A vanpool is a group of eight to 13 people who regularly commute together by leasing a van on a month-to-month basis through VPSI, Inc., the vanpool contractor for the Municipality of Anchorage. Volunteer drivers pick up riders at specific points, drop them off at or near their worksite, and return them to their pickup points at the end of each work day.

There is one primary driver and at least two other back-up drivers for each van. The primary driver rides for free.

The monthly vanpool fare covers all operating, maintenance and insurance costs, which are divided equally among the riders in exchange for a guaranteed seat.

Anchorage Share A Ride requires that all Anchorage vanpools begin or end within the Municipality of Anchorage commute with a minimum of 8 people.
