EXISTING TRANSPORTATION CONDITIONS <br /> TJKM conducted p.m. peak hour turning movement counts at several locations in the <br /> vicinity of the project, and these traffic counts were analyzed to determine the existing <br /> level of service. Most of these counts were taken in June of 1987, and will be <br /> considered as current and up-to-date turning movements for this report. A more <br /> recent p.m. peak hour turning movement count was taken at the intersection of <br /> Airport Way and Arch/Sperry Road in February of 1988. <br /> The existing level of service summary for several intersections in the study area is <br /> shown in Table I. These are intersections that were identified as key or critical <br /> intersections, and are listed in Table I in alphabetical order. <br /> TABLE I <br /> LEVEL OF SERVICE SUMMARY <br /> FOR EXISTING TRAFFIC <br /> NORTH/SOUTH ST EAST/WEST .5 VlC LOS <br /> Airport Way Arch Airport Road 0.34 A <br /> East Frontage Road Arch Road 0.33 A <br /> Frontage Road Hwy 99 NB Off 0.33 A <br /> Frontage Road Hwy 99 SB Off 0.30 A <br /> West Frontage Road Arch Road 0.41 A <br /> West Frontage Road Project Access N/A <br /> Source: TJKM <br /> February 1988 <br /> As can be seen from Table I, the existing traffic conditions in the study area are at <br /> LOS A conditions. This means that there is stable traffic flow at the intersections <br /> analyzed, and there is very slight or no delay. The method used for analyzing the <br /> 1987 turning movement counts is known as the "critical movement" method, and is <br /> based on information from several sources including Interim Materia/ on Highway <br /> Capacity, Transportation Research Circular No. 212, Transportation Research Board, <br /> 1980. A description of the analysis procedure is documented in Appendix A. <br /> 4 <br />
