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