PDAs are areas located around transit where development may <br />occur without necessitating heavy automobile travel. Thus, these areas are currently being <br />targeted for development. <br />In general, LOS along roadways in San Leandro shall be maintained at LOS D or better. <br />However, roadways located within PDAs shall be maintained at LOS E or better. For this <br />study, the LOS performance threshold used for Fairmont Drive is LOS E. <br />Existing Conditions Operational Analysis <br />Existing traffic operations at the three study intersections and along the corridor were <br />assessed using Synchro software. ADT counts and turn movement counts, including <br />pedestrians and bicycles, were provided by the City of San Leandro. The AM and PM peak <br />hour counts as well as roadway and intersection geometry for all three signalized intersections <br />are illustrated in Figure 2. <br />DKS evaluated the existing network performance without the project for two scenarios – with <br />the current signal timing and with optimized signal timing. As shown in Table 2, for the current <br />signal timing all the study intersections currently operate at an acceptable level of service <br />during the AM, midday and PM peak periods. The detailed reports from Synchro are included <br />in Appendix B. <br /> <br />Table 2: Existing Intersection Delay (Seconds)/LOS <br /> Current Timing Optimized Timing <br />Study Intersection <br />Intersection <br />Control AM <br />Peak <br /> <br />Midday <br />Peak <br />PM <br />Peak <br />AM <br />Peak <br /> <br />Midday <br />Peak <br />PM <br />Peak <br />1) Fairmont <br />Drive/Hesperian <br />Boulevard <br />Signalized 37.0/D <br /> <br />38.5/D 44.2/D 35.7/D 39.8/D 38.4/D <br />2) Fairmont Drive/Bayfair <br />Drive Signalized 20.0/B 25.8/C 25.6/C 20.0/B 25.2/C 25.5/C <br />3) Fairmont Drive/E. 14th <br />Street (SR 185) Signalized 33.3/C 31.8/C 45.1/D 33.3/C 31.8/C 39.1/D <br /> <br />The signal timings were optimized based on traffic volumes. DKS assumed that the cycle <br />lengths would not be modified in order not to disturb the coordination along the adjacent <br />corridors of Hesperian Boulevard and East 14th Street. After optimizing the timing, all <br />intersections are expected to perform at an acceptable level of service. <br />169
