The second letter <br />(in parentheses) is the Level of Service for the worst operating movement. <br />As shown in Table 1, all of the study intersections currently operate at LOS C <br />or better. All movements are also at LOS C or better with the exception of the <br />eastbound approach on Line Avenue at the Twin Lakes Road intersection in <br />the p.m. peak hour. Less than ideal operations at side -street intersections are <br />not unusual during the peak periods across the Metro. The 95th percentile <br />queue for this movement is about 200 feet, or eight to ten vehicles. Field <br />observations confirmed the long queue during this period, but also noted that <br />the vehicles are able to keep moving due to the relatively low conflicting <br />volume on Twin Lakes Road. <br />Based on these results, Line Avenue is currently operating acceptably and <br />does not need improvements. <br />d. Warrant Analysis - Twin Lakes Road & 181St Avenue <br />As shown in Figure 2 in the Appendix, the Twin Lakes Road/181St Avenue <br />intersection is under all -way stop control, but appears to be set-up for a future <br />signal system given the number of approach lanes provided. The turning <br />movement counts show that there are significant enough volumes at this <br />intersection that upgrading it to a signalized intersection could be considered. <br />Using the turning movement counts, the volume signal warrants (Warrants 1- <br />3) were reviewed for the Twin Lakes Road/181St Avenue intersection using <br />the methodology from the Minnesota Manual on Uniform Traffic Control <br />Devices. Satisfying one or more warrants indicates that a traffic signal may be <br />appropriate for an intersection. With the existing turning movement volumes, <br />the Twin Lakes Road/181St Avenue intersection does not satisfy any of the <br />volume warrants. <br />Given the satisfactory traffic operations during the peak periods and the <br />failure to satisfy a volume warrant, this review of the existing conditions <br />indicates all -way stop remains an appropriate traffic control at this <br />intersection. Results of the warrant analysis are shown in the Appendix. <br />Traffic Operations Study 4 Line Avenue in Elk River <br />
