20 2026 01 21 Eagle Rock Ave and Oval Road Laurel Avenue Traffic Signal Design Report

Capacity Analysis We conducted capacity analyses for the two study intersections. The results indicate that the proposed traffic signal will not significantly affect traffic operations along Eagle Rock Avenue (County Route 611), while improving the accommodation of turning movements from Oval Road and the Crestmont Country Club driveway. In addition, the proposed left‑turn lanes at both intersections will address existing substandard operations and are expected to adequately accommodate forecasted 95th‑percentile queues. Table 1 summarizes the Build (Unsignalized) and Build (Signalized) Levels of Service (LOS) at each study intersection during the weekday morning and evening peak hours. All capacity analysis worksheets are provided in Appendix C.
