Forecast volumes for the Midday period were not available. The cumulative <br />scenario assumes that the transit-oriented development has been constructed. <br />Cumulative Conditions Operational Analysis <br />Cumulative traffic operations at the three study intersections and along the corridor were <br />assessed using Synchro software. Expected turn movement counts for the future year were <br />provided by the City of San Leandro. The AM and PM peak hour counts as well as roadway <br />and intersection geometry for all three signalized intersections are illustrated in Figure 4. <br />DKS assumed that the cycle length would change from existing conditions for the cumulative <br />year. However, to be conservative it was assumed that coordination priority would remain on <br />the Hesperian Boulevard corridor and the E. 14th Street corridor, as it is today. Therefore, <br />individual intersection timings were optimized but the Fairmont Drive corridor was assumed to <br />operate without coordination in the east-west direction. <br />As shown in Table 6, all study intersections are expected to operate at an acceptable LOS <br />during the Cumulative AM and PM peak periods. The detailed reports from Synchro are <br />included in Appendix B. <br />Table 7 shows the Arterial LOS analysis results. As shown, the corridor is expected to operate <br />at acceptable LOS eastbound during the AM peak period. However, the arterial is expected to <br />operate at LOS F westbound during the AM peak period and PM peak period and eastbound <br />during the PM peak period. Arterial operation improvement in the westbound direction during <br />the PM peak period as compared to existing conditions is due to signal timing modifications. <br /> <br />Table 6: Cumulative Delay (Seconds)/LOS <br />Study Intersection Intersection Control AM <br />Peak <br />PM <br />Peak <br />1) Fairmont Drive/Hesperian Boulevard Signalized 60.4/E 75.9/E <br />2) Fairmont Drive/Bayfair Drive Signalized 21.7/C 36.8/D <br />3) Fairmont Drive/E. 14th Street (SR 185) Signalized 53.9/D 49.9/D <br />Note: Signal retiming assumed for Cumulative condition. Reduction in delay from existing conditions <br />(current signal timing) is due to retiming. <br /> <br />Table 7: Cumulative Arterial LOS <br /> Study Segment Signal Delay <br />(s) <br />Arterial <br />Speed (mph) <br />Arterial <br />LOS <br />AM EB: Hesperian Boulevard to E.14th Street 58.7 10.2 E <br />WB: E. 14th Street to Hesperian Boulevard 149.3 5.1 F <br />PM EB: Hesperian Boulevard to E.14th Street 92.9 7.3 F <br />WB: E.14th Street to Hesperian Boulevard 59.2 9.9 F <br />174
