methodology referenced above, the inbound trips were then assigned to segments on the network. The result of this analysis 'was two sets of project peak hour volumes for each impacted roadway segment on the network. Since one set of volumes represents inbound trip ends and the other represents outbound trip ends, the peak hour volume for each direction for each segment was determined. The capacity analysis for each segment was then done by taking the project trip ends for the segment's peak direction and assessing whether or not this volume was less than the segment's available capacity. Under the proposed land use designation, the greatest peak hour/peak season impact will be the 350 trips generated in the outbound direction. This total is 341 more than the 9 outbound trips generated by the most intense use of the site under the current land use designation. Therefore, the most intense use of the subject property under the proposed land use designation would generate 341 more new peak hour/peak season/peak direction trips than would be generated by the most intense use of the site under the present land use designation. Using a modified gravity model and a hand assignment, these trips were then assigned to roadways on the network. r Capacities for all roadway segments in Indian River County are calculated and updated annually, utilizing the latest and best available peak season traffic characteristics and applying Appendix I methodology as set forth in the Florida Department of Transportation Level of Service -Manual. Available capacity is the total capacity less existing and committed traffic volumes; this is updated daily based upon vesting associated with project approvals. The traffic capacity for the segment of U.S. #1 adjacent to this site is 21650 trips (peak hour/peak season/peak direction) at a Level of Service "D", while the existing peak hour/peak season/peak direction traffic volume on this segment of U.S. #1 is 747 trips (peak hour/peak season/peak direction). The additional 341 peak hour/peak season/peak direction trips created by the proposed Comprehensive Plan amendment will increase the total peak hour/peak season/peak direction trips for this segment of U.S. #1 to approximately 1,088. Based on staff analysis, it was determined that U.S. #1 and all other impacted roads can accommodate the additional trips without decreasing their existing levels of service. Impacted roads are defined in the county's Land Development Regulations as roadway segments which receive five percent (5%) or more daily project traffic or fifty (50) or more daily project trips, whichever is less. - The table below identifies each of the impacted roadway segments associated with this proposed amendment. As indicated in this table, there is sufficient capacity in all of the segments to accommodate the projected traffic associated with the request.
