~~~ KimleyHor„ Supplemental WeekdayNVeekend Traffic Analysis -Final Report <br />l~ and Associates, inc. Home Depot, Pleasanton, CA <br />Operating Conditions and Criteria <br />Levels of service are represented by a letter scale from LOS A to LOS F, with LOS A <br />representing the best performance and LOS F representing the poorest performance <br />under significantly congested conditions. According to the City of Pleasanton <br />requirements, LOS D is an acceptable level of traffic operation at intersections in the <br />study area with the exception of the two intersections in the downtown area -First <br />Street & Vineyard Avenue and Bernal Avenue & First Street / Sunol Boulevard. Per the <br />General Plan, these two downtown intersections are exempt from LOS standards. <br />Based on Pleasanton requirements, traffic analysis to determine level of service was <br />completed using Synchro software at signalized intersections. The Synchro software <br />platforms are based on the methodology of the Highway Capacity Manual. The City of <br />Pleasanton provided the AM peak and PM Synchro models which were updated for use <br />in this evaluation. At the direction of the City, the AM peak signal timing was used for <br />the weekend analysis because it most closely resembles the free timing the City has in <br />place on the weekends. <br />Table 1 relates the operational characteristics associated with each level of service <br />category for both signalized and unsignalized intersections. <br />Table 1 -Intersection Level of Service Definitions <br /> Signalized Unsignalized <br /> (Avg. control , {Avg. control <br /> delay per delay per <br />Level of vehicle vehicle <br />Service Description sec/veh) sec/veh) <br />A Free flow with no delays.
