Centerville 2040 Comprehensive Plan <br /> <br /> <br />R OADWAY S YSTEM F UNCTIONAL C LASS R OADWAYS <br />The functional classification system groups roadways into classes based on roadway function <br />and purpose. Functional classification is based on both transportation and land use <br />characteristics, including roadway speeds, access to adjacent land, connection to important land <br />uses, and the length of trips taken on the roadway. <br />Four classes of roadways are included in the seven-county metropolitan area functional <br />classification system: principal arterials, minor arterials, collector streets, and local streets. Map <br />6-1 shows the existing and planned functional classification of each road in the City of <br />Centerville. Map 6-2 show the existing and forecasted traffic volumes for A-Minor roadways <br />within the City. The following sections describe each functional class in greater detail and <br />indicate which roadways fall into each classification. <br />Minor Arterials <br />Minor arterials maintain a focus on mobility but provide more land access than principal <br />arterials. Minor arterials are intended to serve trips of four to eight miles in length. Within <br />developing areas of the metro, these facilities are spaced between one and two miles apart. <br />Minor arterials connect cities and towns within the region and link to regional business and <br />commercial concentrations. Access points along minor arterials are generally at-grade and <br />typically controlled with signals or stop signs. <br />During peak traffic, minor arterials in developing areas are intended to maintain 30 mph <br />average speeds. As a result, transportation system connections are limited to interstate <br />freeways, other principal arterials, other minor arterials, collectors, and some local streets. Land <br />access is limited to concentrations of commercial and industrial land uses. The Metropolitan <br />eligible for federal funding administered by the Metropolitan Council. <br />r arterials into four types, described below: <br />Minor Relievers is to provide additional capacity in congested corridors. <br />Augmenters: Arterials that supplement the principal arterials system within urban <br />centers and urban communities. <br />Expanders: Arterials that supplement principal arterials in less-densely developed areas <br />of the metro area. <br /> <br /> Page 73 <br /> <br /> <br />
