EXHIBIT C the proposed site. These site generated volumes and how they distribute themselves through the roadway network are shown in Appendix C in Tables C5-A (passenger vehicles) and C5-B (trucks). F. Future Traffic Conditions Future traffic conditions for the year 2018 were then calculated based on the background traffic growth rate of 3% per annum and the ultimate traffic generation estimates for the site. The year 2018 traffic projection assumes full build-out and occupancy of the development. The total base condition traffic without development, estimated for the year 2018, is shown in Table C4 in Appendix C. The total traffic (projected base traffic plus site generated traffic) is shown in Table C6, also in Appendix C. The volume projections shown in Tables C4 & C6 in Appendix C are also shown in figure form in Exhibits A12-A15 in Appendix A. IV. Traffic Analysis The analysis of future traffic conditions in the study area was then undertaken for the year 2018 which was the estimated year that the site was assumed to be built-out and fully occupied (even though construction may be completed sooner). It is likely that signal timing changes could be required at the Fairmont and S. 16 Street and th SH 146 at Wharton Weems Boulevard signals within the study horizon of 2018 so the assumption that signal timings would be optimized for future traffic volume conditions was employed to more accurately reflect future traffic operations. This portion of the traffic impact analysis also employs the traffic simulation model Synchro, part of the Synchro Pro 8.0 Simulation Suite. Synchro was used to input the roadway network geometry and optimize the signal timings. HCS signalized and unsignalized output has been included for completeness as required. HCS output may be found in Appendix D. A. Simulation of Future Traffic Conditions The projected capacity and level of service (for both background traffic and total traffic) for the study year of 2018 are presented in Table 5 for the following cases: 2018 Projected Future Traffic Volume Condition without development traffic with 3%/year background growth rate; 2018 Projected Traffic Volumes with development traffic and with 3%/year background growth rate; Page 14 Voigt Associates, Inc.
