Kimley>))Horn Intersection level of service (LOS) analysis was performed for each of the intersections within the study area using the signalized and unsignalized analysis methodology found in the Highway Capacity Manual (HCM) and Trafficware's Synchro/SimTraffic version 10. Each intersection was analyzed for the weekday PM and Saturday peak hour for the following scenarios: • 2019 Existing Conditions (with two-way ring road), • 2024 Short -Term Background Conditions (without project trips), • 2024 Short -Term Build Conditions (with project trips, without improvements), • 2024 Short -Term Build Conditions (with project trips, with improvements), • 2040 Long -Term Background Conditions (without project trips, with Short -Term improvements), • 2040 Long -Term Build Conditions (with project trips, with Short -Term improvements), The weekday AM peak hour was not included in the analysis due to the lower trip generation nature of retail centers during the AM peak hour the adjacent street. One of the primary measures of effectiveness used to evaluate intersection traffic operations, as defined in the HCM, is level of service (LOS)—a qualitative letter grade (A through F) based on seconds of vehicle delay due to the traffic control device at an intersection. By definition, LOS A conditions represent high - quality operations (i.e., motorists experience very little delay or interference) and LOS F conditions represent very poor operations (i.e., extreme delay or severe congestion). This study used the LOS D/E boundary as an indicator of satisfactory traffic operations. The following graph displays the LOS thresholds for signalized and unsignalized intersections. ,00 OS F LOS F LOS E LOS D LOS E LOS C OS D OS C LOS B LOS B LOS A LOS A Si gnalized Unsignalized Rosedale Center I Traffic Impact Analysis January 2020 Update
