<br />City of Ramsey <br />Comprehensive Plan Amendment <br />Transportation Element <br /> <br />Functional Classification of Roads <br /> <br />The City of Ramsey's current functional classification system for roads is not based on the same <br />system used by other jurisdictions, particularly Anoka County and MnlDOT. A purpose of this <br />plan was make the City's system consistent with other jurisdictions. Figure 3-2 describes the <br />City's current classification system, which includes five functional classes: principal arterials, <br />major arterials, minor arterials, collectors, and locals. Figure 3-3 describes the relationship <br />between these facility types and two competing travel functions, mobility and land use <br />accessibility. <br /> <br />The County and MnlDOT use a system that is based on four functional classes: 1) principal <br />arterials, minor arterials, collectors, and locals. The minor arterial functional class is broad and <br />includes "A" and "B" minor arterials. Tables 3-1 and 3-2 describe the functions of roads under <br />Anoka County's and MnlDOT's systems. <br /> <br />Road Level of Service and Travel Demand <br /> <br />Road Level of Service (LOS) is a way of rating the operating conditions ofa road. LOS "A" <br />through "F", with ,. A" as the highest, describes operating conditions associated with various <br />values of the volume:capacity (V/C) ratio. <br /> <br />The V IC ratio of a road is a direct measurement of the road's ability to meet its mobility function. <br />At values less than 0.90, the V/C ratio indicates the number of vehicles using the road are fewer <br />than the road has capacity to carry. Traffic congestion is non-existent to tolerable when the V/C <br />ratio is less than 0.90. <br /> <br />When the V/C ratio is between 0.90 and 1.00, the road is approaching capacity and the extent of <br />congestion is extreme. V/C in excess of 1.00 indicate that travel demand on the road is greater <br />than the road's carrying capacity. The level of traffic congestion associated with V/C ratios <br />greater than 1.00 is severe and characterized by unsafe conditions where efficient operations are <br />greatly affected. <br /> <br />Table 3-3 shows the relationship between V/C and LOS. <br /> <br />Page 3-10 <br />
