<br />Chapter 4 <br />Environmental Setting, Impacts, and Mitigation Measures <br />O. Transportation and Traffic <br /> <br />(1) Trip Generation <br /> <br />For each of the proposed uses, standard Institute of Transportation Engineers trip genera- <br />tion rates or other trip generation sources were used to estimate the levels of daily, AM, and <br />PM peak hour traffic. Trip generation of individual uses was aggregated by sub-area (the <br />Plan area is divided into 16 sub-areas). Trip generation rates and resultant traffic generation <br />for the Phase II Specific Plan are detailed in a series of tables in Appendix F, Part 5. Overall, <br />the project is projected to generate about 6,998 average daily trips and 411 AM and 713 PM <br />peak hour trips. <br /> <br />(2) Trip Distribution <br /> <br />The City of Pleasanton travel demand model was used to distribute the daily and peak hour <br />traffic from the site to the surrounding areas. The initial model assignment produced a high <br />amount of regional traffic to and from the site. Given the intent of the project to serve local <br />residents more than regional residents, the total amount of regional versus local travel was <br />adjusted. The relative trip values were not changed; rather, the split between local and <br />regional traffic was changed to increase the traffic locally and reduce it regionally. <br /> <br />Table 12 presents the distribution of peak hour and daily trips to Pleasanton's "gateways." <br /> <br />Table 12 <br />Distribution of Peak Period and Daily Trips Associated with the Proposed Specific Plan <br /> <br />IN <br />Number Percent <br /> <br /> <br />OUT <br />Number Percent <br /> <br />TOTAL <br />Number Percent <br /> <br />Pro'eel Tri <br />Catew. <br />1-680 s/o Sunol BI <br />^Pleasaf1~()t1/~unoT Rd <br />Foothill Rd <br />.SOUthGi~a ~~.~~~~ <br />1-580 w/o Foothill Rd <br />Dublin Canyon Rd <br />Dublin BI <br /> <br />NBjlN <br /> <br /> <br />13.29% <br /> <br />22 <br />6 <br />7 <br /> <br />, EBl'N <br />i <br /> <br />5 <br /> <br />5 <br /> <br />TOTAL 10 <br /> <br />1-580 e/o EI Charro Rd <br />lack London <br />Dublin BI <br /> <br /> <br />;SBIIN <br /> <br />1 <br />2 <br /> <br /> <br />TOTAL 2 <br /> <br /> <br />1-680 n/o 1-580 <br />San Ramon Rd <br />Hopyard Rd <br />Hacienda Rd <br />'Santa Rita Rd~. <br /> <br />4 <br />1 <br />5 <br />2 <br /> <br />2 <br /> <br />Source; Dowling Associates <br /> <br />137 <br />
