Exclusion lanes are lanes for a particular class of vehicle, excluding all others. The most common examples are the bus-only, bicycle and car pool/diamond lanes.
Exclusion lanes are intended to change traffic patterns.
The effectiveness of exclusion lanes varies with the location of their placement. Their effectiveness is greatest when there are clear alternatives that are easier to use than violating the lane restriction.
Exclusion lanes cost approximately $2,000-10,000 each, for an entrance area.
Some parking may be lost to reinforce the restrictions.
Transit Service Impacts:
Exclusion lanes may impede transit service or scheduling, though they are often constructed for the benefit of transit vehicles.
Emergency Services Impacts:
Emergency response vehicles are not generally impeded by vehicle exclusion lanes. The Portland Fire Bureau reviews all Exclusion lanes proposed on their primary response routes.
