• <br />• <br />Indian River County 1 Impact Fee Update Study <br />To calculate the interstate and toll (I/T) facility discount factor, the loaded highway network <br />file was generated for the Greater Treasure Coast Regional Planning Model v3.4 (GTCRPM). <br />A select link analysis was run for all traffic analysis zones located within Indian River County <br />in order to differentiate trips with an origin and/or destination within the county versus <br />trips with no origin or destination within the county. <br />Currently, the only interstate/toll facilities in Indian River County are 1-95 and the Florida <br />Turnpike (SR 19). The limited access vehicle miles of travel`(Limited Access VMT) for trips <br />with an origin and/or destination within Indian River County was calculated for the <br />identified limited access facilities. The total Indian Riyer, County VMT was calculated for all <br />trips with an origin and/or destination within Indian/River County for all roads, including <br />limited access roads, located within Indian RiverCounty. <br />The I/T discount factor of 17.3 percent was determined by.,,dividing the total Limited Access <br />VMT by the total Indian River County VMT. By applying thissfactor to the total Indian River <br />County VMT for each land use in theifee,schedule, tf educed VMT is then representative <br />of only the roadways which are funded by impact fees Appendix B, Table B-1 provides <br />further detail on this calculation. <br />Tindale -Oliver & Associates, Inc. <br />January 2014 <br />Indian River County <br />105 Impact Fee Update Study <br />
