n ffo~ 0 BOOK 9 rnf?98 Rural Roads Principal Arterial: A rural link in a network of continuous routes serving corridor movements having trip length and travel density characteristics indicative of substantial statewide or interstate travel and existing solely to serve traffic. This network would consist of interstate routes and other routes designated as principal arterials. Minor Arterial: A rural link in a network joining cities and larger totqns and providing intrastate and intercounty service at relatively high (55 mph) overall travel speeds with minimum interference to through movement. This net- work would primarily serve traffic. Major Collector: A road which serves major intracounty travel corridors and traffic generators and provides access to the arterial system. Minor Collector: A road which provides service to small local communities and links the locally important traffic gen- erators with their rural hinterland. Local Road: A local road serves primarily to provide access to adjacent lard and for travel over relatively short distances. Urban Streets Major Thoroughfares: Major thoroughfares consist of interstate, other freeway and expressway links, and major streets that provide for the expeditious movement of volumes of traffic within and through urban areas. Minor Thoroughfares: Minor thoroughfares are important streets in the city system and perform the function of collecting traffic from local access streets and carrying it to the major thoroughfare system. Minor thoroughfares may be used to supplement the major thoroughfare system by facilitating a minor through traffic movement and may also serve abut- ting property. Local Street: A local street is any link not of a higher order urban system and serves primarily to provide direct access to abutting land and access to higher systems. It offers the lowest level of mobility and through traffic is usually deliberately discouraged. Specific Type Rural or Urban Streets Cul-de-sac: A cul-de-sac is a short street having but one end open to traffic and the other end being permanently terminated and a vehicular turn around provided. -8-
