Florida Department of Transportation District One Interstate Planning for I-4 and I-75 October 30, 2012

Purpose  Define Deficiencies on the Interstate Mainline –Capacity needs between 2012 and 2050 if no improvements were made  Determine Years in which Interstate Mainline Widening is Needed  Provide Recommendations for Managed Lanes Study Limits in D1  Determine feasibility of replacing bridge structures 1

Traffic Methodology – Growth Rate Development  Available FDOT Traffic Data –FTI DVD  Recent and Current Studies –Central Polk Parkway IJR, I-75 SIMR, I-75/SR 951 IMR, I- 75/Everglades IJR  Cost Feasible Models –CPP IJR, SR 951 IMR –Lee-Collier, Sarasota-Manatee-Charlotte  Population Growth and Projections Reviewed –Census Data from 2000 and 2010 –BEBR Medium Projections 2010 to 2035  Recommended Growth Rate Selected I-4 Growth Rate = 2.0%I-4 Growth Rate = 2.0% I-75 Growth Rate = 2.5%I-75 Growth Rate = 2.5% 2

Traffic Methodology – Capacity Analysis  Geometry and Functional Classification of Mainline Segments was Reviewed  LOS Standard Applied Segment by Segment –Rural Interstate – LOS C –Urban Interstate – LOS D  FDOT Generalized Tables used to Determine Capacity Thresholds –6 lane –8 lane  Recommended Growth Rate Applied to 2011 AADTs 3
