Functional Classifications <br />The quantity and associated vehicle weight of traffic using streets is a critical factor affecting the rate <br />at which pavement and roadbeds deteriorate. Eugene divides streets into five categories called <br />functional classifications (FC),each representing a different volume and type of vehicular usage. <br />The MicroPaver terminology for functional classification/section rankis identified as follows: <br />Major Arterial (FC-1) - (A):Major Arterials are usually four or more lanes and generally connect <br />various parts of the region with one anotheoutside worldThey serve <br />as major access routes to regional destinations such as downtowns, universities, airports, and similar <br />major focal points within the urban area. Major Arterials typically carry an average of more than <br />20,000 vehicles per day. Major Arterials receive high priority maintenance. <br />Minor Arterial (FC 2) - (B):Minor Arterials are typically two or three lanes. These streets provide <br />the next level of urban connectivity below major arterials. In most cases their main role tends to be <br />serving intra-city mobility.Minor Arterials carry between 7,500 and 20,000 vehicles per day. Minor <br />Arterials receive priority maintenance. <br />Major Collector (FC-3) - (C):Major Collectors can be found in residential, commercial,and <br />industrial areas.They typically carry between 2,500 and 7,500 vehicles per day. Major Collectors <br />have a higher priority for maintenance than local streets. <br />Neighborhood Collector (FC-4) - (D):Neighborhood Collectors are found only in residential <br />neighborhoods and provide a high degree of access to individual properties in a neighborhood. They <br />typically carry between 1,500 and 2,500 vehicles per day. <br />Local (FC-5 - (E):Local streets provide access to individual properties along the roadway.They are <br />narrow, slow-speed, and low-volume service facilities. They typically carry fewer than 1,500 vehicles <br />per day, and receive low priority maintenance. Local streets are also referred to as Residential streets. <br />The following graph illustrates both centerline miles and lane miles by improvement type and <br />functional classes. <br />1400 <br />1300 <br />1200 <br />Mileage by Functional Class -Improved and Unimproved <br />1100 <br />1000 <br />900 <br />800 <br />700 <br />600 <br />500 <br />400 <br />300 <br />200 <br />100 <br />0 <br />Major ArterialMinor ArterialMajor Colls.Neigh.
