IV. LEVEL OF SERVICE ANALYSIS <br /> Level of Service (LOS) Analysis was applied to the study <br /> intersections for the A.M. peak hour. The analysis was conducted <br /> by the methodology described in the 1985 Highway Capacity Manual <br /> for unsignalized intersections . The methodology is based on the <br /> conflicts between each individual turn movement versus all of the <br /> other approach movements . The LOS is calculated for each <br /> approach according to the reserve capacity available to <br /> accommodate additional traffic . With a greater reserve capacity, <br /> more gaps are available in the main traffic flow to allow turns . <br /> As traffic volumes increase, the reserve capacity and the number <br /> of acceptable gaps in the traffic stream diminish. The City' s <br /> current traffic policy establishes an intersection LOS "C" or <br /> better during both peak hours . Table B summarizes the LOS <br /> results for each growth scenario. The detailed LOS calculations <br /> are available from the City of Tracy Department of Public Works . <br /> Table C <br /> Level of Service Summary <br /> (AM Peak Hour) <br /> Intersection Larch/Tracy Larch/Holly <br /> Existing ' A A <br /> Existing Plus Cumulative A C <br /> Growth Without Project <br /> (Year 2000) <br /> Existing Plus Project A A <br /> Existing Plus Cumulative B C <br /> Growth With Project <br /> (Year 2000) <br /> A brief description the traffic impacts associated with each <br /> scenario follows: <br /> a.
