  1. Advanced Toll Modeling Presented By Jim Fennessy Fennessy Associates For Toll Subcommittee July 14, 2010

  2. Miscellaneous Toll Modeling Developments • Open Road Tolling (TOLDATA file additional fields) • Hot-Lane (Value Pricing) Tolls • Ramp-to-Ramp • Distance-Based Tolls • Discrete Tolls – Toll based upon the number of toll facilities crossed • Congestion-Pricing Tolls

  3. Distance-Based and Discrete Tolls • Not currently used by Florida’s Turnpike

  4. Congestion-Pricing Toll Modeling • Internal to the Assignment Process • Iteration Toll Rate Calculations based upon Congestion • Intra-iteration (Lambda Calculations) • Turnpike-Sponsored TRANPLAN Modifications • Rates Variable by Toll Agency (Company) • Suspended by Economy Downturn

  5. Open Road Toll Modeling • Voyager Script Checks • Impedance inputs to both TRANPLAN and Voyager identical • Single Iteration assignments are essentially identical

  6. Open Road Toll Modeling • Reasonableness Check – Northbound

  7. Open Road Toll Modeling • Reasonableness Check – Southbound

  8. HOT Lane Tolls • Voyager Script Checks • Impedance inputs to both TRANPLAN and Voyager identical • Single Iteration assignments are essentially identical

  9. Hot Lane Tolls • Reasonableness Check – Sample Links

  10. Ramp-to-Ramp Tolls • Software to convert TRANPLAN input data to Voyager format • Single toll company for one iteration produced identical results • All toll companies failed – network coding is a problem for Voyager (Citilabs to review) • Reporting features needed (Citilabs to review)

  11. Ramp-to-Ramp Tolls • Reasonableness Check – Sample Link

  12. AdvanceToll Modeling • Questions?
