· New traffic signals at intersections meeting signal warrants included in future CIP funding years. In a sense, then, the "Existing Plus Approved" intersection operational descriptors may be conservative in that additional intersection modifications may well accompany the added growth being projected, thus improving the LOS at certain intersections. Regional Growth The "Existing Plus Approved" model run used projected 2010 levels of region-wide growth rather than "buildout" projections since this model run was originally done as a mid-term projection. The "Baseline Report" shows the assumed level of regional growth. At 2010, East Dublin, Dougherty Valley, and Livermore are far short of their buildout (General Plan) levels of intensity. Area development impacts not only the direct utilization of Pleasanton's 1-580 interchanges it shares with Dublin/Dougherty Valley traffic, but also the models' balancing of home-to-work/shopping trips and, thus, indirectly, the distribution of trips in Pleasanton. If the "Existing Plus Approved" land use scenario were modeled with "Buildout" regional development, the local distribution of trips and cut-through trips would be different, and, thus, it is likely some intersection LOS would be different. Freeway congestion is projected to be worse on both 1-580 and 1-680, and, thus, cut-through traffic routes are impacted when local street capacity is available. Proiected Intersection Operation Tables 7 and 8 show the projected LOS at all 127 intersections in the AM and PM peak hours, respectively. As for "Existing," individual intersection leg delay is included as well as overall delay. The number of intersections with a peak-hour operation at LOS E/F is projected to increase from 12 to 33. The change in peak-hour LOS at major intersections is shown graphically on Figures 5 and 6. Overall delay also significantly increases throughout much of the City. LOS A intersections decrease from 45 percent and 35 percent of total intersections to 23 percent and 17 percent (AM and PM, respectively). LOS C or better intersections are reduced from 87 percent to 70 percent of total AM and PM intersections. In addition, delay within individual service levels also increases, contributing to overall increase in delay. SR 05:070 Page 8
