The Cumulative AM and PM peak hour traffic conditions were determined at the study intersections. The Cumulative traffic volumes consist of General Plan buildout conditions derived from the City's travel demand model. The peak hour levels of service were calculated for the study intersections. 4. The Cumulative+Project traffic conditions were estimated for the proposed Ruby Hill project. This involved adding the project's peak hour trips to the Cumulative peak hour volumes, and calculating the peak hour levels of service for the study intersections. 5. The traffic operations results were analyzed to determine if the proposed mitigation measures would be required to provide acceptable peak hour levels of service at the study intersections. Acceptable levels of service are based on the City's standard, which is LOS D for this area. Existing+Approved Traffic Volumes The list of study intersections was determined by City staff. Dowling Associates, Inc. provided the City with computer plots from the City model showing the contribution of project traffic to the surrounding street system. Once the list of analysis locations was selected, traffic data was obtained from the City of Pleasanton's database at each of the following study intersections (Figure 1): (1) Stanley Boulevard & Valley Avenue (2) Bernal Avenue & Valley Avenue (3) Vineyard Avenue & Isabel Avenue (4) Vineyard Avenue & Ruby Hill Boulevard (5) Bernal Avenue & Vineyard Avenue (6) Vineyard Avenue &Project Driveway The traffic volumes shown in Figure 2 (and in Appendix Table A-1) were used to perform the traffic operations analysis at these intersections.
