Data from these <br />studies include trip generation, trip length, and percent new trips for each land use. This <br />information has been used in the development of impact fees and the creation of land use plan <br />category trip characteristics for communities throughout Florida and the U.S. <br />TOA estimates trip generation rates for all land uses in a transportation impact fee schedule <br />using data from studies in the Florida Studies Databasearidthe Institute of Transportation <br />th o ? "i <br />Engineers'(ITE) Trip Generation reference report (9 edition) In instances, when both ITE Trip <br />Generation reference report (9th edition) and Florida Studies tripjgeneration rate (TGR) data are <br />itete available for a particular land use, the data is typically blended together to increase the sample <br />size and provide a more valid estimate of the average number of trips; generated per unit of <br />development. If no Florida Studies data is available, only TGRdata from the TE reference report <br />is used in the fee calculation. <br />The trip generation rate for each respectiveland use is tie" <br />using machine counts that <br />record daily traffic into and out of the sitetstudied The traffic cont hoses are set at entrances to <br />residential subdivisions forthe residentialnd uses and att,all access points for non-residential <br />land uses. <br />The trip length information is�obt edkthrough origin destination surveys that ask respondents <br />• <br />vr <br />whereethey>came frommprior to<arriving at the 'site and where they intended to go after leaving <br />the site: The results ofthese surveys;were used eto estimate average trip length by land use. <br />The percent <br />destination survey <br />new trip variable is <br />has published an article <br />new trip variable is based on assigning each trip collected through the origin - <br />process a trip Wpe (primary, secondary, diverted, and captured).
