° Traffic Circulation <br />BOOK 81 WAGE 46" <br />The greatest impact on the county as a result of the proposed <br />Indian River Mall is likely to be on the road network. The total <br />number "of trips generated by the project is likely to exceed <br />35,000 trips per day. In order to, assess the impact on the <br />system, an analysis, was done to identify the expected traffic <br />distribution and determine the improvements that would be required <br />to maintain county level of service standards. Detailed <br />information regarding the. project's impact on the traffic <br />circulation system, including project volumes by roadway segment, <br />service level analysis by segment, and intersection analysis-, are <br />found in the DRI ADA. <br />A staff analysis was done to verify applicant's traffic <br />information and conclusions. The analysis was done .by using the <br />Florida Standard Urban Transportation Model Structure (FSUTMS) <br />computer program which was also .used in the county's Traffic <br />Circulation Element. This model simulated the effects of the <br />proposed mall on the county's future roadway network for the years <br />1995 and 2010. The model was first updated to reflect the <br />existence of the project in the base population and employment <br />data. <br />When the model is "run", automobile trips are assigned to road <br />segments based on the attractors and generators. A comparison of <br />the traffic volumes to roadway capacities is used to identify the <br />projected level of service on any road segment. It is then <br />possible to identify the specific improvements that would be <br />required. This review shows substantial traffic generated as a <br />result of this project. Where projected volumes are shown to <br />exceed a roadway's capacity at the adopted level of service, <br />necessary improvements are identified. The improvements that are <br />required as a result of this project are shown on the following <br />tables. Several of these improvements have already been <br />identified in the comprehensive plan; however, the timing of these <br />projects changes considerably with the proposed project. These <br />changes will prevent the degredation of service levels below <br />acceptable minimum standards. <br />The improvements reflected in the tables below are proposed as <br />amendments to the traffic circulation element. Tables 4.7.2 and <br />4.7.3 of the Traffic Circulation Element will be amended to <br />incorporate the referenced improvements. These tables also <br />identify the projected roadway network classification, volume, and <br />level of service for 1995 and 2010. <br />W'..' a CODM W Ogg) 5Z10, 4 <br />Roadway <br />Existing Condition <br />Comp Plan <br />Project <br />to Proposed Condition <br />Timing <br />Require <br />S.R. 60:66th Ave -58th Ave <br />Fran 4 lane div. to 6 lane div. <br />by 2010 <br />1993 <br />58th Av:26th St. -12th St. <br />Fran 2 lane South to 4 lane div. <br />2010 <br />1993 <br />of SR 60 and North <br />of Ryanwood Drive- <br />way <br />I <br />43rd Ave: SR 60 to 12th St. <br />Fran 2 lane to 5 lane or 4 lane <br />2010 <br />1993 <br />div. <br />26th St:66th Ave -58th Ave <br />Fran unpaved 2 lane to 2 lane <br />19951 <br />1993 <br />paved <br />16th St.: Old Dixie to US1 <br />Fran 3 thru lanes to 4 thru lanes <br />2010 <br />1993 <br />with turn lanes with turn lanes <br />if needed, may <br />monitor <br />1 the Traffic Circulation Element identifies the need to acquire an additional fifty (50) <br />feet of right-of-way by 1995; no other improvements are identified. <br />24 <br />
