Dynamic Tolling Assignment Model for Managed Lanes presented to Advanced Traffic Assignment Sub-Committee presented by Jim Hicks, Parsons Brinckerhoff September 14, 2012

Overview Prior discussions on Managed Lanes in Florida Features of Phase I Model Implementing and Testing Model Results of Model Discussion 1

Conceptual Requirements Flexible – able to accommodate most “flavors” of managed lanes within a unified approach Behaviorally Sensitive – Includes variables that are important to selection and use of a managed lane Policy Sensitive – Has the ability to test different Managed Lane Policies (e.g., tolls, congestion sensitive) Ease of use – Model implementation compatible with FSUTMS and a reasonable runtime Understandable – No “black boxes” 2

Managed Lane “Flavors” HOV - only Express Lanes Truck Only Reversible lanes HOT – SOV pay Dynamic Tolling Open Road Tolling Dedicated Facilities Pre-pay and/or Pay per use (toll booths) ITS Solutions (Traffic calming, speed advisories, incident management) 3

Behavioral Variables Time savings Cost Trip Purpose Income/Value of time Time of Day Household Structure (e.g. daycare?) Employment type (on-time requirements) 4

Managed Lane Policy Dimensions Willingness to pay – toll cost per minute saved Toll Cost – congestion related Separate managed lanes and general purpose lanes 5

Data Requirements Willingness to Pay Toll Cost as a function of congestion level Auto Demand Highway Network 6

Adaptations Fixed Toll – subset of toll policy Allows multiple toll policies Allows for multiple markets income stratified Purpose Stratified Can still do accell/decell at toll booths 20

Strengths Planning Level Application No a priori assumption of toll Assures no congestion on toll facility Useful tool for evaluating LOS / Revenue Goals Testing toll policies Customized for WTP 21

Weaknesses No mode shift assumed from transit Congestion represented in daily assignment Statewide model application No sensitivity to SE data of travelers 22

FSUTMS Apps? Urban HOT lanes Urban Tolled Freeways Rural Turnpike? – willingness to pay characteristics need evaluation Not sufficient for multi-modal corridors, but could play a role 23
