r - Nov $ 7 1992 Foa 88 FAa 32 The number of /Average Weekday Trip Ends associated with the most intense use of the subject property under the present zoning is 264. This was determined by multiplying the 45 DU's (most intense use), by ITE's factor of 5.86 Average Daily Trip Ends/DU. The number of peak hour/teak season/inbound trip ends associated with the most intense use of the subject property under the present zoning is 16. This as determined by taking 658 (local measurement) of 45 DU's (most intense use), multiplied by ITE's factor of 0.55 peak hour trip end@/DU. Similarly, the number of peak hour/peak season/outbound trips associated with the most intense use of the subject property under the present zoning is 9. This was determined by taking 358 (local measurement) of 45 DU's (most intense use), multiplied by ITE's factor of 0.55 peak hour trip ends/DU. The number of new p.m. peak hour outbound trips associated with this request was determined by multiplying ITE's factor of 62.59 Average Weekly Vehicle Trip Ends/1000 gross square feet by 145,300 square feet (the most intense use) to get the total daily trips. Dividing the total daily trips by 2 to get the 24 hour outbound volume, applying the ITE Shopping Center Use p.m. peak hour outbound factor (11%),, and multiplying that number by 708 ( based on the ITE Manual) to ensure that only new trip ends are counted, indicates that the total p.m. peak hour outbound trips for the proposed use will be 350. A similar methodology was used to project p.m. inbound trips. Instead of the 118 factor used for outbound trips, a 10.38 factor was used to estimate p.m. peak hour inbound trips. Using the same 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. 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 G 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. .7 28 � r
