In many stations, the Tri Met comes about every twenty minutes. For the wheelchair traveler, the accessible doors to the Tri Met are clearly marked to be accessible by a button with the universal wheelchair symbol. All one has to do is press it and the door automatically opens and a ramp comes out. Inside there is a space designated for wheelchairs and other handicapped people, including a large button to notify the driver when you are at your stop and the ramp is needed.
