3.2. 2040 Future Roadway Capacity Improvement Needs <br />To identify the need for potential future capacity improvements, Metropolitan Council 2040 <br />forecasts were compared to planning -level roadway capacities for Principal and A -Minor <br />Arterial Roadways. Planning -level roadway capacities used for this analysis are illustrated in <br />Table 6 below. Based on this comparison, there are several arterial roadways within the City <br />that will meet or exceed capacity to accommodate forecasted 2040 travel demands. These <br />include I -35W, Snelling Avenue, Lexington Avenue, Rice Street, and TH 36. Each of these <br />roadways currently exhibits a Level of Service (LOS) of E or F during at least one peak period, <br />as shown in Figure 6. This indicates that motorists experience some level of congestion. Due to <br />overall population growth, these conditions are anticipated to worsen under 2040 conditions. <br />Table 6: Planning -Level Roadway Capacity <br />Facility Type <br />Daily Two-way Volume <br />Lower <br />Threshold <br />Higher <br />Threshold <br />Two-lane Undivided <br />10,000 <br />12,000 <br />Two-lane Divided or Three -lane Divided <br />15,000 <br />17,000 <br />Arterials <br />Four -lane Undivided <br />18,000 <br />22,000 <br />Four -lane Divided or Five -lane Undivided <br />28,000 <br />32,000 <br />Four -lane Freeway <br />60,000 <br />80,000 <br />Freeways <br />Six -lane Freeway <br />90,000 <br />120,000 <br />Eight -lane Freeway or Higher <br />Calculated on a <br />segment -by -segment basis <br />Chapter 5—Transportation (DRAFT) <br />Adopted XXXXXX XX, 2017 <br />Page X-31 <br />
