c. Level of Service <br /> Los A An intersection capacity analysis was conducted <br /> for the existing intersections per the Highway <br /> - Capacity Manual. Intersections are assigned a <br /> "Level of Service" letter grade for the peak hour <br /> of traffic based on the number of lanes at the <br /> intersection, traffic volumes, and traffic control. <br /> Los C Level of Service A (LOS A) represents light <br /> a: �s- <br /> traffic flow (free flow conditions)while Level of <br /> Service F (LOS F) represents heavy traffic flow <br /> (over capacity conditions). LOS D is considered <br /> acceptable in urban conditions. The pictures on <br /> LOS D=Acceptable the left represent some of the LOS grades (from <br /> 1 *� a signal controlled intersection in San Jose, CA). <br /> `.t <br /> The LOS results for the existing study hours are <br /> shown in Table 3.2. These are based on the <br /> existing traffic control and lane configurations as <br /> cos F=Unacceptable existing <br /> in Figure 3.1. The existing turning <br /> r _ movement volumes from Figure 3.2 were used <br /> - � in the LOS calculations. The LOS calculations <br /> were done using SYNCHROT"' software. <br /> source: city of Ramsey County's existing timing plans were <br /> San Jose,CA used in the analyses. The complete LOS <br /> calculations are included in the Appendix. <br /> Table 3.2 — Existing Level of Service (LOS) <br /> Intersection Existing P.M.
