Item 7b Staff Report PLANNING COMMISSION March 23, 1988 SUBJECT: Review of Standard Requirements for a Traffic Study in North Pleasanton APPLICANT: City of Pleasanton PURPOSE: To review and adjust, as may be necessary, the standard assumptions used in project-related, short term traffic studies. ATTACHMENTS: 1. Table IV, City of Pleasanton Trip Generation Rates, of the Existing Standard Requirements BACKGROUND In 1984 the City adopted a series of **standard assumptions** to be used in all project-related, short-term traffic studies. These assumptions standardize trip generation rates, trip distribution, and level of service calculation methodology. Originally based on recognized standards used by traffic engineers, adjusted for expected Pleasanton experience, these standard assumptions were meant to be monitored and adjusted as necessary to best reflect the north Pleasanton experience. Modifications were made in 1985 and 1986, affecting primarily the level of service calculation methodology. Proposed modifications to the trip generation rates in 1986 were deferred until Pleasanton-specific studies were made. This report summarizes the empirical data collected to date in north Pleasanton and suggests modifications as found appropriate. TRIP DISTRIBUTION Present Assumptions The distribution for all north Pleasanton office, R&D, and light manufacturing trips is now set forth in tables which distribute traffic from each site within north Pleasanton. These trips were based on a distribution reflecting the 1984 TSM survey place-of-residence of north Pleasanton employees and analysis of actual traffic patterns. As can be seen in Table 1, the place-of-residence distribution has changed enough to warrant adjustment. - 1 -
