Kimley)))Horn <br />In future scenarios, an intersection with unsatisfactory operations was first addressed through signal timing <br />modifications, or if that was not possible, through implementation of an intersection or roadway <br />improvement. Due to the restrictive nature of the land use surrounding the existing roadway alignments, a <br />limited number of roadway improvements were considered possible. Only those improvements that could <br />be implemented without major reconstruction were implemented as mitigation. <br />In order to determine the impacts of the project on the transportation network, a traffic operations analysis <br />was performed on the roadway network surrounding the site. The analysis process included determining <br />level of service at each of the study intersections for Existing, Short -Term Background (2024), Short -Term <br />Build (2024), Long -Term Background (2040), and Long -Term Build (2040). SimTraffic reports are included <br />in Appendix E. For each scenario, five one -hour simulations were conducted in SimTraffic, and the average <br />of those model runs were reported. <br />In each of the following sections, a description of potentially unsatisfactory operational characteristics is <br />summarized for each scenario modeled. A table summarizing the LOS and delay by intersection is provided <br />for each scenario. For signalized intersections, the overall LOS is reported, and for unsignalized <br />intersections, the overall intersection and worst movement LOS is reported. The SimTraffic reports were <br />reviewed to identify individual movements that experience unsatisfactory level of service and delay. Only <br />in instances where an individual movement experiences an unsatisfactory measure of effectiveness will the <br />movement information be summarized. Supplemental tables are provided in Appendix C that provides <br />individual movement LOS and delay for each intersection. <br />EXISTING (2019) OPERATIONS SUMMARY <br />Table 2 provides Existing (2019) delay and LOS for both the weekday PM and Saturday peak hours. Overall <br />intersection delay and LOS is reported for signalized intersection while overall / worst movement delay and <br />LOS is reported for unsignalized intersections. Table A and Table B (included in Appendix C) provides <br />the delay and LOS for each individual movement for the weekday PM and Saturday peak hours. <br />TABLE 2: EXISTING (2019) LEVEL OF SERVICE SUMMARY <br />Intersection <br />Fairview Avenue at TH 36 EB <br />Control <br />Signal <br />Weekday PM <br />Delay <br />11.4 <br />Peak <br />LOS <br />B <br />Saturday Peak <br />is Delay <br />12.9 <br />LOS <br />B <br />Fairview Avenue atTH 36 WB <br />Signal <br />27.2 <br />C <br />38.1 <br />D <br />Fairview Avenue at Rosedale Center Driveway #1 <br />Signal <br />15.9 <br />B <br />23.6 <br />C <br />Fairview Avenue at County Road B2 W <br />Signal <br />25.6 <br />C <br />30.9 <br />C <br />County Road B2 W at Rosedale Center Driveway #2 <br />Signal <br />10.5 <br />B <br />15.5 <br />B <br />County Road B2 W at Rosedale Center Driveway #3 <br />Signal <br />15.6 <br />B <br />25.5 <br />C <br />County Road B2 W at Snelling Avenue SB <br />Signal <br />22.0 <br />C <br />28.1 <br />C <br />County Road B2 W at Snelling Avenue NB <br />Signal <br />6.1 <br />A <br />11.6 <br />B <br />Internal Intersection #1A <br />Stop Control <br />2.0 / 6.3 <br />A / A <br />3.7 / 7.4 <br />A / A <br />Internal Intersection #113 <br />Stop Control <br />2.9 / 3.2 <br />A / A <br />6.3 / 7.8 <br />A / A <br />Internal Intersection #2 <br />Stop Control <br />6.1 / 9.5 <br />A / A <br />9.6 / 17.2 <br />A / C <br />Internal Intersection #3 <br />Stop Control <br />5.9 / 12.2 <br />A / B <br />8.4 / 17.1 <br />A / C <br />Internal Intersection #4 <br />Stop Control <br />2.3 / 8.2 <br />A / A <br />2.9 / 10.3 <br />A / B <br />Rosedale Center I Traffic Impact Analysis <br />January 2020 Update <br />
