Additionally, all individual <br />movements are anticipated to operate at a LOS D or better, except for the westbound through movement <br />at the intersection of Lexington Avenue and Grey Fox Road in the PM peak hour, which operates at LOS <br />E. The westbound through movement only has two vehicles in the PM peak hour and is therefore, not <br />anticipated to have a significant impact on other turning movements. In the simulation, delay can fluctuate <br />significantly based on when those two vehicles arrive within the signal timing due to the modeling nature of <br />SimTraffic. <br />The SimTraffic reports are provided in Appendix D. All 95th percentile queues are anticipated to remain <br />within their respective storage bays. The eastbound approach at Lexington Avenue & Grey Fox Road <br />should be monitored, going forward. SimTraffic is reporting a 95th percentile queue of approximately 220 <br />feet, which has the potential to impact operations at site access 1, however SimTraffic Shows minimal delay <br />at the site access. <br />DESIGN YEAR (2040) NO-BUILD CONDITIONS <br />A capacity analysis was performed for Design Year (2040) No-Build conditions in order to develop baseline <br />operating conditions for the design year. The existing intersections were modeled with the existing geometry
