The county transportation system encompasses all of the
San Juan Islands. It brings people and goods into the community and provides
the means by which they can move freely within each island from one activity to
another. It works closely with Washington State Department of Transportation, Washington
State Ferries, County Road Administration Board and the Town of Friday Harbor.
Public Works produces studies on traffic, vehicle speeds, accident history, engineering
improvements, capacity management, marine facilities, pavement ratings, maintenance
of roads, and reconstruction of existing services. These studies help us in
planning for future transportation needs.

Traffic Studies
San Juan
County transportation system monitors traffic volumes, vehicle speeds, and vehicle
classification annually. Individual traffic studies are also performed on
an as needed basis.
Traffic classifiers, are set in key locations on county roads and records the number
of vehicles passing a given location on an average day.
San Juan
County uses Annual Average Daily Traffic (AADT). AADT is calculated with seasonal
fluctuation conversion factors established by Washington State Department of Transportation.
