Trott Brook Crossing EAW Traffic Study Review January 6, 2022 <br />No Build Conditions <br />To determine how the study intersections and site accesses will operate under year 2026 and 2040 no <br />build conditions, an intersection capacity analysis was completed using Synchro/SimTraffic software. <br />The no build conditions analyzed impacts from background traffic growth and the adjacent North <br />Brook Meadows development. <br />Year 2026 No Build Conditions <br />Results of the year 2026 no build conditions intersection capacity analysis shown in Table 5 indicates <br />that the study intersections are expected to continue operating at an acceptable overall LOS A during <br />the a.m. and p.m. peak hours with the proposed roadway geometry and traffic controls. <br />Table 5.

The delay shown represents the worst side -street approach delay. <br />The following information summarizes the operational and/or queuing issues that warrant <br />consideration as traffic volumes increase. <br />• Nowthen Boulevard NW / Ramsey Boulevard NW <br />o The side -street delay in the eastbound direction is nine (9) seconds for the a.m. peak and 19 <br />seconds for the p.m. peak hour. The 95th percentile queues in the eastbound direction are <br />expected to be approximately 50 feet during the a.m. peak hour and 120 feet during the p.m. <br />peak hour. <br />o Side -street delay is expected to increase by approximately two (2) seconds per vehicle during <br />the a.m. peak and four (4) seconds per vehicle during the p.m. peak as compared to existing <br />conditions. <br />Page 14 <br />
