Florida Department of Transportation District One Interstate Planning for I-4 and I-75 October 30, 2012
2
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
