DKS assumed that signals would be retimed as <br />part of this project (cycle lengths to remain the same), which resulted in an improvement in <br />operations for the Hesperian Boulevard intersection as compared to existing conditions with <br />the current timing plans. Compared to the existing conditions with optimized timings, delay <br />increases at most locations but operations remain at acceptable LOS. The detailed reports <br />from Synchro are included in Appendix B. Appendix C includes graphics showing the <br />expected queues. Queuing is expected to increase somewhat along the corridor with the <br />project addition. <br /> <br />Table 4: Existing Plus Project Delay (Seconds)/LOS <br />Study Intersection Intersection <br />Control AM Peak Midday <br />Peak PM Peak <br />1) Fairmont Drive/Hesperian <br />Boulevard Signalized 36.9/D 39.0/D 38.7/D <br />2) Fairmont Drive/Bayfair Drive Signalized 21.9/C 27.0/C 34.6/D <br />3) Fairmont Drive/E. 14th Street <br />(SR 185) Signalized 35.6/D 31.6/C 42.8/D <br />Note: Signal retiming assumed for plus project condition. Reduction in delay compared to <br />existing conditions is due to signal retiming. <br /> <br />Table 5 shows the Arterial LOS analysis results. As shown, the corridor is expected to operate <br />at operate at LOS F for all peak periods in both the eastbound and westbound directions. This <br />represents a degradation from LOS E to LOS F for the AM and Midday peak periods in the <br />eastbound direction, correlated to an increase in delay of seven (7) seconds or less compared <br />to the existing optimized conditions. For all other directions and peak periods, LOS F would be <br />maintained. <br />It should be noted that coordination of the Fairmont Drive corridor would improve arterial <br />operations. However, it is not possible to coordinate the Fairmont Drive corridor while <br />maintaining current coordination patterns along Hesperian Boulevard and E. 14th Street, as <br />the two corridors have different signal timings. <br /> <br />Table 5: Existing Plus Project Arterial LOS <br /> <br />Study Segment <br />Signal <br />Delay <br />(s) <br />Arterial Speed <br />(mph) <br />Arterial <br />LOS <br />AM <br />EB: Hesperian Boulevard to E.14th Street 60.8 9.9 F <br />WB: E. 14th Street to Hesperian <br />Boulevard 69.0 9.1 F <br />Midday <br />EB: Hesperian Boulevard to E.14th Street 68.3 9.2 F <br />WB: E. 14th Street to Hesperian <br />Boulevard 74.1 8.7 F <br />PM <br />EB: Hesperian Boulevard to E.14th Street 95.1 7.1 F <br />WB: E.14th Street to Hesperian <br />Boulevard 67.9 9.0 F <br />173
