Table 3.4 presents the <br />freeway mainline segment analysis for Alternative 2 conditions and compares mainline segment performance <br />to Buildout Cumulative With Update conditions. The Alternative 2 scenario does not include any freeway <br />mainline capacity improvements, consequently, the capacities are consistent with the Buildout Cumulative <br />With Update scenario. Appendix B presents detailed HCS worksheets for mainline analysis. <br />The same segments that are forecast to be deficient in the Buildout With Update scenario are also deficient <br />in Alternative 2. In the AM peak, 34 out of 60 freeway segments operate at a deficient LOS and in the PM <br />peak 27 out of 60 operate at a deficient LOS. In total 40 segments are deficient in one or both peaks. The <br />deficient segments are: <br />AM Peak Hour: <br />1-5 <br />Northbound <br />• Between Culver Drive and Jamboree Road <br />• Between Jamboree Road and Tustin Ranch Road <br />• Between Tustin Ranch Road and Red Hill Avenue <br />• Between Red Hill Avenue and Newport Avenue <br />• Between Newport Avenue and SR-55 <br />• North of SR-55 <br />Southbound <br />• Between Jamboree Road and Culver Drive <br />• Between Tustin Ranch Road and Jamboree Road <br />• Between Red Hill Avenue and Tustin Ranch Road <br />• Between Newport Avenue and Red Hill Avenue <br />• North of SR-55 <br />1-405 <br />Northbound <br />• Between Culver Drive and Jamboree Road <br />• Between Jamboree Road and MacArthur Boulevard <br />• Between MacArthur Boulevard and SR-55 <br />Southbound <br />• Between Jamboree Road and Culver Drive <br />• Between SR-55 and MacArthur Boulevard <br />• Between Bristol Street and SR-55 <br />• Between SR-73 and Bristol Street <br />SR-55 <br />Northbound <br />• Fair Drive to SR-73 <br />• McFadden Street/Sycamore Avenue to 1-5 <br />Southbound <br />• Between Dyer Road and MacArthur Boulevard <br />• Between Edinger Avenue and Dyer Road <br />• Between McFadden Street/Sycamore Avenue and Edinger Avenue <br />• Between 1-5 and McFadden Street/Sycamore Avenue <br />SR-73 <br />Northbound <br />• Between MacArthur Boulevard and University Drive <br />• Between University Drive and Jamboree Road <br />• Between Jamboree Road and Birch Street <br />• Between Birch Street and Campus Drive <br />• Between Campus Drive and SR-55 <br />Southbound <br />• Between University Drive and MacArthur Boulevard <br />• Between Campus Drive and Birch Street <br />• Between SR-55 and Campus Drive <br />• Between SR-55 and Bear Street <br />SR-261 <br />Southbound <br />• South of El Camino Real <br />PM Peak Hour: <br />1-5 Northbound • Between Culver Drive to Jamboree Road <br />• Between Jamboree Road to Tustin Rach Road <br />• Between Tustin Ranch Road and Red Hill Avenue <br />• Between Red Hill Avenue and Newport Avenue <br />Iteris, Inc. 174 <br />
