<br /> <br />2.2.Existing Roadway Capacity and Safety <br /> <br />Roadway capacity and roadway safety are two key indicators of how well the roadway system <br />is meeting the c <br />understand capacity and safety issues within Ramsey. <br />2.2.1.Existing Roadway Capacity <br /> <br />congestion. Capacity is largely dependent upon the number of lanes. below lists <br />Table 1 <br />planning-capacity.Additional variation (more or less <br /> <br />capacity) on an individual segment is influenced by a number of factors including: amount of <br />access, type of access, peak hour percent of traffic, directional split of traffic, truck percent, <br />opportunities to pass, and amount of turning traffic, the availability of dedicated turn lanes, <br />parking availability, intersection spacing, signal timing and a variety of other factors. <br />Table 1: Planning-level Urban Roadway Capacities <br />Daily Two-way Volume <br />Lower Higher <br />Facility Type Threshold Threshold <br />Two-lane Undivided 10,000 12,000 <br />Two-lane Divided or Three-lane Divided 15,000 17,000 <br />Arterials <br />Four-lane Undivided 18,000 22,000 <br />Four-lane Divided or Five-lane Undivided 28,000 32,000 <br />Four-lane Freeway 60,000 80,000 <br />Six-lane Freeway 90,000 120,000 <br />Freeways <br />Calculated on a <br />Eight-lane Freeway or Higher <br />segment-by-segment basis <br />2.2.2.Existing Capacity Problems on Arterial Roads <br /> <br />At the planning level, capacity problems are identified by comparing the existing number of <br />lanes with current traffic volumes. and illustrate the existing number of lanes <br />Table 2Figure 3 <br />on collector and arterial roadways within the city. illustrates existing traffic volumes <br />Figure 4 <br />on Principal Arterial, A-Minor Arterials and other significant roadways within the city. <br />As shown in the table, US 10 has four lanes throughout the city, as do portions of CSAH 56 <br />(Ramsey Boulevard), CSAH 57 (Sunfish Lake Boulevard), CSAH 83 (Armstrong Boulevard), <br />and CSAH 116 (Bunker Lake Boulevard). All other arterial roadways have two lanes. Most of <br />the arterials in Ramsey currently exhibit traffic volumes below or within the range of the <br />planning level capacity thresholds shown in ; however, existing volumes on TH 47 (St. <br />Table 1 <br />Francis Boulevard) exceed these thresholds in the southeastern area of the city. This indicates <br />that this roadway may be experiencing some levels of congestion during peak travel periods. <br />Chapter X Transportation (DRAFT) Page X-11 <br />Adopted XXXXXXX XX, 2017 <br /> <br />
