3. Line Avenue Alternative Options & Analysis a. Line Avenue Alternative Options The potential conversion of Line Avenue to a cul-de-sac between Main Street and Twin Lakes Road could occur at three different locations: • Alternative A - disconnect Line Avenue between the intersections with Twin Lakes Road and 5t" Street • Alternative B — disconnect Line Avenue between the intersections with 5t" Street and 3rd Street. • Alternative C — disconnect Line Avenue between the intersections with 3rd Street and Main Street/181 st Avenue. b. Traffic Volume Adjustments To be able to analyze the study intersections with the different Line Avenue alternatives, the existing volumes were shifted around to correspond to the different layouts. The following assumptions were made in order to complete these shifts for the different alternatives: • Standard trip generation rates apply to houses and businesses that have access directly, or indirectly through public roads, to Line Avenue. • Existing volumes at the end points of the study network will roughly balance with these shifts. For example, Twin Lakes Road has an existing a.m. peak hour volume of 503 vehicles on the southbound approach. For any alternative, this southbound approach will continue to have about 503 vehicles, although the percentages to the turning movements will change. • Drivers will select the closest replacement route based on the roadway network, not based on delays or perceived delays. The final volumes can be seen in the capacity analysis section of the Appendix for each scenario. c. Line Avenue Alternatives Level of Service Analysis The forecasted turning movement volumes for the different alternative scenarios were used to re -analyze the study intersections. As before, the LOS calculations were done in accordance with the 2010 Highway Capacity Manual using VISTROTM software. A summary of the LOS results for the alternative Line Avenue layouts for each peak hour is shown in Tables 2 and 3. The complete LOS calculations, which include queue lengths and grades for all individual movements, are included in the Appendix. Traffic Operations Study 5 Line Avenue in Elk River
