Traffic volumes were derived by adding the long range trips to the long <br />range background traffic volumes. As shown, all study intersections will operate at acceptable LOS for <br />the 2035 with project conditions. <br />Table 7 - AM/PM Peak Hour Intersection Analysis <br />Long Range (2035) With Project Conditions <br />Signalized Intersections AM Peak Hour PM Peak Hour LOS "E" <br />ICU Method ICUILOS ICUILOS OK <br />Main Street at Dyer Road 0.865 / D 0.894 / D <br />Main Street at MacArthur Boulevard 0.731 / C 0.8201 D x <br />Main Street at Sandpointe Avenue 0.350 / A 0.547 / A <br />Main Street at Sunflower Avenue 0.689 / B 0.810 / D <br />MacArthur Place at MacArthur Boulevard 0.808 / D 0.794 / C x <br />SR-55 SB Ramps at MacArthur Boulevard 0.7921 C 0.744 / C x <br />SR-55 NB Ramps at MacArthur Boulevard 0.847 / D 0.7101 C <br />Red Hill Avenue at MacArthur Boulevard 0.6421 B 0.840 / D x <br />HCM Method Delay/LOS Delay/LOS <br />SR-55 SB Ramps at MacArthur Boulevard 20.7 / C 18.3 / B x <br />SR-55 NB Ramps at MacArthur Boulevard 21.8 / C 18.2 / B <br />Note: ICU Delay is in seconds/vehicle <br />Determination of Significant Impact <br />Traffic impacts for the proposed project are determined by comparing the traffic conditions in the <br />future without the project to future conditions with the project, giving special consideration to locations <br />where LOS is not forecast to be adequate. Traffic impacts are identified as significant if the proposed <br />project results in a significant change in traffic conditions on a roadway or intersection. The thresholds <br />to determine significant traffic impacts for the proposed project are as follows: <br />MacArthur Place South EIR - 2011 Addendum <br />41 <br />75B-86
