City of Ramsey Comprehensive Plan Amendment Transportation Element purpose of this pen was make the City's system consistent with other jurisdictions. Figure 3-2 describes the ICity's current classification system, which includes five functional classes: principal arterialsf? major arterials, minor arterials, collectors, and locals. Figure 3-3 describes the relaiionship between these facility types and two competing travel functions, mobility and land! use accessibility. The County and Mn/DOT use a system that is based on four functional classes: 1) principal minor ~terials, collectors, and locals. The minor arterial functional class is broad arterials, and includes "A" land "B" minor arterials. Tables 3-1 and 3-2 describe the functions of roads under Ano~ County's and Mn/DOT's systems. Road Level of S6rvice and Travel Demand Road Level of Se~ "A" through "F", various values of 'vice (LOS) is a way of rating the operating conditions of a road. LOS with "A" as the highest, describes operating conditions associated with the volume:capacity (V/C) ratio. The V/C ratio of la road is a direct measurement of the road's ability to meet its mobility function. At values less than 0.90, the V/C ratio indicates the number of vehicles using the road are fewer th~ n the road has capacity to carry. Traffic congestion is non-existent to tolerable when th~ V/C ratio is less than 0.90. When the V/C ral ~o is between 0.90 and 1.00, the road is approaching capacity and the extent of congesti, ~n is extreme. V/C in excess of 1.00 indicate that travel demand on the road is greater tha a the road's carrying capacity. The level of traffic congestion associated with V/C ratios g~.eater than 1.00 is severe and characterized by unsafe conditions where efficient operatio~ are greatly affected. Table 3-3 shows the relationship between V/C and LOS. Page 3-9 los
