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 tragic 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 <br />AM Peak Hour <br />PM Peak Hour <br />LOS "E" <br />ICU Method <br />ICU /LOS <br />ICU /LOS <br />OK <br />Main Street at Dyer Road <br />0.862 / D <br />0.892 / D <br />Main Street at MacArthur Boulevard <br />0.725 / C <br />0.809 / D <br />x <br />Main Street at Sandpointe Avenue <br />0.322 / A <br />0.542 / A <br />Main Street at Sunflower Avenue <br />0.673 / B <br />0.793 / C <br />MacArthur Place at MacArthur Boulevard <br />0.763 / C <br />0.776 / C <br />x <br />SR -55 SB Ramps at MacArthur Boulevard <br />0.771 / C <br />0.719 / C <br />x <br />SR -55 NB Ramps at MacArthur Boulevard <br />0.833 / D <br />0.691 / B <br />Red Hill Avenue at MacArthur Boulevard <br />0.636 / B <br />0.835 / D <br />x <br />HCM Method <br />Delay /LOS <br />Delay /LOS <br />SR -55 SB Ramps at MacArthur Boulevard <br />20.3 / C <br />17.51 B <br />x <br />SR -55 NB Ramps at MacArthur Boulevard <br />21.41 C <br />17.6 / B <br />rvoLe: ic.0 — intersecuon %.apacity umization. ueiay is in seconasivenicie.
