Tremendous <br />dela s with continuousl increasin ueue len ths. <br /> <br />The following intersections will be analyzed using the leu methodology: <br /> <br />· Grand A venue and Avenue <br />· Grand Avenue and Brookhollow Drive <br />· Grand A venue and Dyer Road <br />· Dyer Road and Main Street <br />· Red Hill A venue and Dyer /Barranca Parkway <br /> <br />Signalized Intersections - Highway Capacity Manual (HCM) Methodology <br /> <br />The following study intersections are Caltrans intersections and will therefore be analyzed using the Highway <br />Capacity Manual (HeM) 2000 methodology for signalized intersections. <br /> <br />· Grand Avenue and SR-55 SB off-ramp <br />· Dyer Avenue and SR-55 SB off/on-ramp/Hotel Terrace Drive <br />· Dyer Avenue and SR-55 NB off/on-ramp <br /> <br />This methodology estimates the average total delay (in average seconds per vehicle) for each of the <br />movements to or from the minor street, and determines the level of service for each movement. <br /> <br />Just as with the leu methodology, the HeM delay forecast translates to a Level of Service designation, <br />ranging from LOS "A" to LOS "F". The descriptions of operating conditions for each Level of Service are <br />very similar to the LOS descriptions for signalized intersections. A summary description of each Level of <br />Service for signalized intersections, and the corresponding delay, expressed in seconds per vehicle, is <br />provided on the following chart: <br /> <br />Crazy Horse Square <br />Food and Retail Center <br /> <br />April, 2006 <br /> <br />- 5 - <br /> <br />75~13~ 01 <br />
