The existing+approved traffic volumes were provided by <br />the City of Pleasanton in the associated Synchro traffic analysis software files. The <br />peak hour Levels of Service (LOS) were then calculated for the 28 study <br />intersections. <br /> <br />,. <br /> <br />2. The Existing+Approved+Project traffic conditions were then estimated for the Bernal <br />Commercial project. This involved estimating the project's trip generation and trip <br />distribution; adding the project's peak hour trips to the Existing+Approved peak hour <br />volumes; and calculating the peak hour LOS for the 28 key intersections. <br /> <br />... <br /> <br />3. The level of service results were then analyzed to determine if any mitigation <br />measures would be needed to maintain an acceptable peak hour LOS at the study <br />intersections for the Existing+Approved+Project analysis scenario. The acceptable <br />LOS is based on The City's standard, which is Level of Service D (some exemptions <br />exist). Traffic operational analyses were used to determine the need for mitigation <br />measures. Mitigation measures were then developed by the City of Pleasant on. <br /> <br />, <br /> <br />Existilrlg+ApplJ'Oved Traffic Volumes <br /> <br />Traffic data was obtained from the City of Pleasant on for the study intersections (Figure 1) of: <br /> <br />., <br />i (I) Bernal & Case (Signalized) <br />"1 (2) Bernal & First/Sunol (Signalized) <br />J (3) Bernal & 1-680 SB (Stop) <br />l (4) Bernal & Kottinger (All-way Stop) <br />.~ <br />l (5) Bernal & Main (Stop) <br />I <br /> (6) Bernal & Valley (Signal) <br />1 (7) Bernal & Vineyard (N) (Signal) <br />.I <br />l (8) Bernal & Vineyard/Tawny (Signal) <br />j (9) First & Kottinger/Spring (Signal) <br />l (10) First & Neal (Signal) <br />J Traffic Analysis Page 3 <br />Bernal Commercial Development, Pleasanton <br />
