f. Line Avenue Alternatives Comparison <br />Based upon the analyses completed in the above sections, the three <br />alternatives for Line Avenue were compared according to LOS, travel time <br />impacts, likely mitigation needs, and traffic signal need at Twin Lakes <br />Road/181 st Avenue. Table 6 shows this overview of the various analyses. <br />Table 6 — Line Avenue Alternatives Comparison <br />As shown in Table 6, the existing network operates acceptably and the <br />alternatives are not necessary based purely on the intersection operations. Of <br />the three alternatives, Alternative A has the least overall impact on the study <br />network. If other reasons suggest that changes to the Line Avenue corridor <br />are needed, Alternative A is recommended. <br />Regardless of the scenario, a southbound left turn lane on Twin Lakes Road <br />at the Line Avenue intersection would increase safety. An eastbound right <br />turn lane on Line Avenue at that same intersection would also benefit <br />operations for all scenarios except Alternative A, when a cul-de-sac would be <br />placed on Line Avenue at Twin Lakes Road. <br />Traffic Operations Study 9 Line Avenue in Elk River <br />Time <br />Impact <br />Scenario <br />•- <br />MitigationTravel <br />Signal <br />Needs <br />Warranted <br />routes <br />- <br />Existing <br />All acceptable __ <br />__ <br />At Twin Lakes <br />No <br />Rd/Line Ave <br />Alternative A <br />All acceptable 59%-21% <br />35%-25% <br />None <br />No <br />Issues at Twin <br />At Twin Lakes <br />Alternative B <br />50%-16% <br />Lakes Rd/Line Ave <br />44%-52% <br />Rd/Line Ave <br />No <br />Alternative C <br />Issues at Twin 47%-12% <br />45%-118% <br />At Twin Lakes <br />No <br />Lakes Rd/Line Ave <br />Rd/Line Ave <br />As shown in Table 6, the existing network operates acceptably and the <br />alternatives are not necessary based purely on the intersection operations.
