August 2, 2007 Florida Department of Transportation 3 SERPM-6 Summary Most current and advanced SE FL model Time-of-day model with feedback (AM peak, PM peak and Off-peak) Mode choice for non-motorized, auto occupancy and all transit systems Includes HOV lanes, and toll model for Turnpike and other toll roads Base year is 2000, target year is 2030

August 2, 2007 Florida Department of Transportation 4 SERPM-6 Enhancements for Managed Lanes Analysis Develop networks for 2010, 2018, and 2030 Add High-Occupancy-Toll (HOT) lanes capability Each Link Class has a time and cost function: –3+ Carpools use only time –DA and carpool 2 use cost, which includes toll

August 2, 2007 Florida Department of Transportation 5 HOT Lanes Method Implemented with SERPM-6 framework Model seeks equilibrium of impedance (time and equivalent cost) HOV 3+ has no toll HOV 2 and drive alone are assessed tolls Value of time ($1.00 = 5.1 minutes) was calibrated in the toll model (mainly Turnpike) 24 hours, transponders, no toll collection delay

August 2, 2007 Florida Department of Transportation 6 Toll Calculation Function of the V/C on the managed lanes Logit function Several toll ranges explored Final function ranged between $.00 and $0.25 per mile

August 2, 2007 Florida Department of Transportation 7 Alternatives NO-Build Alternatives  2010 : Base year networks, 2010 interpolated zonal data  2018 : Base year networks, 2018 interpolated zonal data  2030 : 2030 networks, 2030 zonal data Build Alternatives  2 Managed lanes on each direction of I-95 in the study area  Replaced HOV lanes, removed HOV slip ramp methodology, included access points at designated locations only (See next slide)  Modified the I-95/I-195 interchange  No changes in zonal data, same as No-Build

August 2, 2007 Florida Department of Transportation 9 Original Access Points Contd. Starting north going southbound: Park and ride location:  N of I-595 Griffin road location Miami/Broward county line location Golden Glades interchange location Between NW 95th St. and NW 103rd St. location SR 112 Location

August 2, 2007 Florida Department of Transportation 10 New Access Points (not ) New Access Points (not recommended)

August 2, 2007 Florida Department of Transportation 11 Tests Conducted Modeling HOT lanes is still in research No HOT lanes calibration data is available Schedule constraints – major model development usually takes more time Tests were conducted to meet the expected performance measures All tests were conducted on 2030 Build Alternative

August 2, 2007 Florida Department of Transportation 12 Tests Conducted Contd. 1. Original access points, 13¢ minimum toll, linear toll function 2. Access points at each interchange N of GG, 13¢ minimum toll, linear toll function 3. New access points, 5¢ minimum toll, linear toll function 4. New access points, 0¢ minimum toll, linear toll function 5. Original access points and 5¢ minimum toll, linear toll function 6. Original access points and 0¢ minimum toll, linear toll function 7. Original access points, 5¢ minimum toll, logit toll function 8. Original access points and 0¢ minimum toll, logit toll function

August 2, 2007 Florida Department of Transportation 13 Macro Model Results Entire corridor of interest was divided into 8 segments Segments 1,2,3,4 are general purpose (GP); segments 5,6,7,8 are HOT Weighted average performance measures were reported Average speeds, average volumes and toll revenues were used to compare alternatives

August 2, 2007 Florida Department of Transportation 14 Macro Model Results Contd. Results Summary  Improved GP lane performance  Improved average speeds  Reduced volumes  Improved HOT lane performance  Significantly improved average speeds  Significantly increased volumes
