1 Ramp-to-Ramp Toll Modeling Presented By Presented By Jim Fennessy Fennessy Associates Michael W Doherty URS Corporation For Model Task Force Meeting Orlando, Florida November 29, 2007
2
2 Ramp-to-Ramp Toll Modeling v Jim Fennessy: – History and Development v Michael W Doherty: – Application at Florida’s Turnpike
3
3 Development History of Ramp-to-Ramp Toll Modeling v CTOLL v UTPS -- UROAD v Toll Facilities Model v Other Miscellaneous Toll Modeling Development Toll Modeling Development v Ramp-to-Ramp Toll Modeling
4
4 CTOLL v Conversion of cost to time based upon average income in study area v Equilibrium highway load parameter: ranges from 0.02 (income = $100k) to 0.10 (income = $20k)
5
5 CTOLL CTOLL = ( 1248 * IVTT) / ( EIP * INCOME) TIMEC TIMEC 1248 – factor to convert income in dollars/year to cents/minute (assumes 2080 work hours/year) (assumes 2080 work hours/year) IVTT – Coefficient for In-Vehicle Travel Time (i.e. : Florida – 0.02) EIP – Expendable Income Percentage (Range : 10 – 35 %) INCOME – Average regional household income TIMEC – Coefficient of Time, Statistical Estimation of Mode & Route Choice based on Survey Data Collected Route Choice based on Survey Data Collected (i.e. : Orlando – 0.0469, Tampa - 0.0492, Jacksonville – 0.0489) (i.e. : Orlando – 0.0469, Tampa - 0.0492, Jacksonville – 0.0489) Example CTOLL – Jacksonville Region =0.0736, Clay Co =0.0798, St Johns Co =0.0511 St Johns Co =0.0511
6
6 UTPS -- UROAD v Up to 20 toll categories v Coded in the TRANPLAN cost field v TOLLS – toll in dollars for each category (converted to time via CTOLL) v SERVT – service time in minutes v Toll links should be coded with zero distance on links to turn off capacity restraint calculation

8
8 Toll Facilities Model v Current FSUTMS Toll Model v TOLDATA file – CTOLL (overrides any parameter) – A-NODE and B-NODE – Toll in dollars – Service time in minutes : seconds – Toll facility identification – Number of lanes – Toll type ramp (no accel/decel) or barrier

9 TOLL FACILITIES MODEL Link Representation D A-B Decel Link B-C Toll Link C-D Accel Link B C A
10
10 Miscellaneous Toll Modeling Developments v Open Road Tolling (TOLDATA file additional fields) v Discrete Tolls – Toll based upon the number of toll facilities crossed v Toll Avoidance Areas – Help identify use of facility without a paying toll u Is the area an error in coding? u Is the area a close up issue with the tolling scheme?
11
11 Ramp-to-Ramp Toll Modeling v Latest Toll Collection Methods – Ramp-to-Ramp (Card System) – Barrier – Electronic Tolling (SunPass) – Discount Pricing (Discrete Tolling) – Open Road Tolling – Variable Pricing (X-Lanes) v Flexible for all cases v Software Modifications

13
13 Ramp-to-Ramp Toll Modeling v Network Restructure v Pseudo Links – Turn Prohibitors / Penalties – Selected Links v Pseudo to Real Links v Assignment by Iteration v Output File – Real Links Software Solutions:

15 Ramp-to-Ramp Toll Modeling Toll Matrices converted into a comma delimited format for input to TRANPLAN
16
16 Ramp-to-Ramp Toll Modeling Software Output : – Ramp-to-Ramp Detail Report u Volumes u Estimated Revenue u Ramp ID’s – Company Summary – DBF Output for Other Software Interface

17 Ramp-to-Ramp Toll Modeling Ramp-to-Ramp Detail Report
18
18 Ramp-to-Ramp Toll Modeling Company Summary Report
19
19 Florida Turnpike Application v Issues with : – Supporting Survey data for Toll Roads – CTOLL – Overstating short trips on Toll Roads – Sensitivity to Speeds and Capacities
20
20 Florida Turnpike Application CTOLL = ( 1248 * IVTT) / ( EIP * INCOME) TIMEC TIMEC CTOLL = Cost Time in Mode & Route Choice Time in Mode & Route Choice Surveys have shown that the CTOLL varies by Trip Length by Trip Purpose by Income
21
21 Florida Turnpike Application CTOLL = (1/VOT) * 0.6
22
22 Florida Turnpike Application Investment Grade Model Toll Mode Choice Assignment Zone to Zone Variations Ramp to Ramp Pathing Toll versus Free Trips Costs by Mode by Payment Method Variable Volume/Delay Curves Use of Posted Speeds Assignment of Toll & Free Trips Costs by Mode by Payment Method
