S. Long Range (2035) Without Project Conditions <br />This section develops the Long Range (2035) traffic conditions in the study area, without the proposed <br />project. It includes development of the buildout traffic conditions in the study area based on traffic <br />growth projections provided by the OCTAM 3.3 model applied to existing traffic patterns. The year <br />2035 was selected for analysis based on the latest OCTA OCTAM 3.3 traffic model buildout year 2035. <br />The 2035 traffic model assumes construction of direct-access HOV drop ramps at SR-55/Alton Parkway. <br />To forecast traffic growth conditions for the year 2035, the OCTA OCTAM 3.3 traffic model data was <br />used as the basis for producing the refined 2035 future intersection turning movement volumes. Figure <br />7 illustrates the resulting Long Range (2035) Without Project AM and PM peak hour volumes. Table 4 <br />summarizes the results of the level of service analyses for this scenario. Appendix G contains the <br />analysis worksheets for the Long Range (2035) Without Project Conditions. <br />Table 4 - AM/PM Peak Hour Intersection Analysis <br />Long Range (2035) Without Project Conditions <br />Signalized Intersections AM Peak Hour PM Peak Hour LOS "E" <br />ICU Method ICU/LOS ICU/LOS OK <br />Main Street at Dyer Road 0.862 / D 0.892 / D <br />Main Street at MacArthur Boulevard 0.725 / C 0.809 / D x <br />Main Street at Sandpointe Avenue 0.322 / A 0.542 / A <br />Main Street at Sunflower Avenue 0.673 / B 0.793 / C <br />MacArthur Place at MacArthur Boulevard 0.763 / C 0.776 / C X <br />SR-55 SB Ramps at MacArthur Boulevard 0.771 / C 0.719 / C x <br />SR-55 NB Ramps at MacArthur Boulevard 0.833 / D 0.691 / B <br />Red Hill Avenue at MacArthur Boulevard 0.636 / B 0.835 / D x <br />HCM Method Delay/LOS Delay/LOS <br />SR-55 SB Ramps at MacArthur Boulevard 20.3 / C 17.5 / B x <br />SR-55 NB Ramps at MacArthur Boulevard <br />N ICU -I 21.4 / C 17.6 / B <br />ate. -ntersection Capacity utilization.
