They include major gateways such as Valley Avenue/Bernal Avenue, Hopyard <br />Road/I-580 eastbound off-ramp, and Bemal Avenue/I-680 southbound off-ramp, in addition to <br />those congested in the "Existing" scenario. <br /> <br />Freeways <br /> <br />The 2010 projection places additional traffic on all movements of I-580 and 1-680 within the <br />Tri-Valley. Where existing congestion is already severe (LOS E/F), such as eastbound 1-580 in <br />the evening, the increased traffic is moderate since there is little available capacity. Morning <br />traffic increases extend congestion for westbound vehicles into Pleasanton. The "off-commute" <br />directions of traffic on 1-580 (eastbound in AM, westbound in PM) become congested. 1-680 <br />conditions remain relatively the same due to constraints in Fremont, at the 1-580/I-680 <br />interchange, and State Route 84, which keep traffic on 1-680 in Pleasanton from rapidly <br />growing. <br /> <br />POSSIBLE TYPES OF "MITIGATIONS" <br /> <br />Congested intersections can be addressed in a number of ways. Intersections, if unsignalized, <br />can be signalized, which for the unsignalized intersections reported here will typically result in <br />operation of LOS B or better. Intersections canbe widened to increase capacity for key <br />movements. New streets can be built to redistribute traffic away from congested intersections. <br />Existing streets can be xvidened or otherwise modified to attract new traffic to a "quicker" route, <br />also changing distribution and reducing traffic at a congested intersection. Intersection signal <br />timing can be adjusted to minimize total delay or to concentrate delay in certain movements <br /> <br />SR 05:070 <br />Page 9 <br /> <br /> <br />
