Based on the daily traffic, capacity and LOS defined above, the existing roadway <br />congestion levels were analyzed. Figure 7 illustrates those existing roadway segments with <br />congestion levels that are approaching or exceeding capacity based on the Metropolitan <br />Council Travel Demand Model. Table 9 summarizes the mileage of congested roadways and <br />roadways approaching congested conditions. <br />Overall, 27 percent of the total state highways in the county are at or over capacity while <br />another 19 percent are approaching capacity. By comparison only, 2 percent of county <br />roadways are at or over capacity and 5 percent are approaching capacity. <br />Table 9 - Existing (Year 2015) Roadway Capacity Deficiencies Summary <br />Roadway Near or Approaching Capacity <br />Class. <br />,c or Over Capacity <br />OnLOS Length (Mile) L, ' Length (Mile) <br />Freeway' <br />Expressway2 <br />Divided <br />Arterial3 <br />Undivided <br />Arterial4 <br />Collector <br />Road5 <br />D <br />Subtotal <br />C <br />D <br />Subtotal <br />C <br />D <br />Subtotal <br />C <br />D <br />5.43 <br />0.18 <br />5.60 <br />3.04 <br />6.58 <br />9.61 <br />0.88 <br />2.51 <br />3.39 <br />Subtotal <br />C <br />D <br />Subtotal <br />9.9 <br />5.41 <br />15.31 <br />4.63 <br />6.00 <br />10.63 <br />E 4.59 <br />F 5.55 <br />Subtotal 1014 <br />E 3.49 moil <br />F 4.43 <br />Subtotal 7.92 <br />E 0.00 <br />F 2.56 <br />Subtotal 2.56 <br />E 4.42 <br />F 6.46 <br />Subtotal 10.88 <br />E 2.24 <br />F 2.38 <br />Subtotal 4.63 <br />Total <br />44.54 36.13 <br />Table Notes: LOS E/F roadways operate at or over capacity; LOS C/D roadways operate near or approaching capacity. <br />' A freeway is a divided roadway with limited access and no traffic signals or other traffic control. <br />2 An expressway is a high speed, multi -lane, divided highway which is generally an arterial road with a posted speed greater than <br />55 mph. Most intersections are at -grade, although grade separated interchanges may exist. <br />A divided roadway has a raised median separating opposing traffic, left -turn lanes and right -turn lanes. <br />4 An undivided roadway does not have a raised median separating opposing traffic or left -turn lanes for turning traffic. <br />5 A collector roadway collects traffic from local roads and connects them with arterials; usually lower speed for shorter distances. <br />Source: Metropolitan Council Travel Demand Model <br />ANOKA COUNTY 2040 TRANSPORTATION PLAN UPDATE CHAPTER 3 - EXISTING CONDITIONS <br />29 <br />
