For purposes of implementing the requirements of RCW 47.01.425 and 47.17.001, relative to the transportation commission, the following definitions shall apply:
Commission -- When commission is used in this chapter, it refers to the transportation commission.
Connecting link -- Connecting links should provide system continuity, including needed alternate routing of regionally oriented through-traffic or access to major regional-based public facilities or traffic generators. Generally, links bypass the central business district and/or the central city and form loops and beltways.
Connection to places -- Places may be considered connected if they are within approximately two miles of a state highway.
Corridor -- A corridor may vary depending on the characteristics of a region and the use of the facilities. The corridor limits used by the commission to analyze a state highway route will be as described by the metropolitan planning organization (MPO) or regional transportation planning organization (RTPO) for the area where the route is located.
Parallel highway route -- Parallel route consideration is used to analyze alternative routes within the same corridor. Outside a corridor, a route should be considered a viable highway route if it meets the other criteria in this chapter.
Population equivalency of one thousand or more -- To determine the equivalent population of a recreation area, refer to the WSDOT publication, "Guidelines for Amending Urban Boundaries, Functional Classifications, and Federal-Aid Systems."
Rural highway route -- A rural highway route is the portion of a route that lies outside a federal urban area boundary.
Urban highway route -- An urban highway route is the portion of a route that is within a federal urban area boundary.
