The intersection analysis was performed using Synchro (v11) software, which implements procedures described in the Highway Capacity Manual, 61h Edition. Vehicle turning movement counts were collected at the study intersection during both the AM and PM peak hours on Wednesday, November 16, 2022 which are included in Appendix E. A peak season factor was applied to estimate existing traffic volumes based on the FDOT Florida Traffic Online (FTO) data for Indian River County included in Appendix F. Signal timings data provided by Indian River County are included in Appendix G. The study intersections were analyzed during existing (2023) and total traffic (2023) conditions. Total traffic volumes were developed by adding anticipated project trips to existing volumes. Vested traffic from the Indian River Service Center (FPL) and Venetian Grove were included within the background growth and excerpts from these projects are included in Appendix H. Vested traffic from the latest Indian River County Links Maintenance Report, provided in Appendix D, were also included in the total traffic volumes. Intersection development worksheets and Synchro output reports for the study intersection is provided within Appendix H and Appendix I, respectively. Figure 3 illustrates turning movement volumes at the study area intersection during the AM and PM peak hour timeframes, respectively. The results of the intersection analysis is presented in Table 2. As shown in Table 2, the study intersection operates with acceptable overall LOS and delay during existing traffic conditions during the AM and PM peak hour. During AM and PM peak hour total traffic conditions, the intersection of SR 60 & 981h Avenue is expected to operate with a LOS F and excessive delay primarily due to the failing northbound and westbound approaches (PM peak hour only). With the implementation of the following improvements to the study intersection of SR 60 & 9811 Avenue, the intersection is anticipated to operate with acceptable LOS and delay during the AM and PM peak hours under total traffic conditions: • An exclusive northbound right turn lane • An additional westbound left turn lane • An additional southbound receiving lane • Protected phasing for both the eastbound and westbound left turn movements • Permissive -overlap phasing for the northbound right turn movement Table 2: Intersection Analysis Retreat at Citrus Ridge I Rezoning Traffic Impact Analysis May 20231 Kimley-Horn and Associates, Inc.
