2 Agenda Dynamic Pricing Overview Parameter Adjustments Preparing For Phase 2 Lessons Learned 2 I-95 Southbound heading towards Downtown Miami during AM Peak Period

3 Dynamic Pricing Overview Original Administrative Rules Min $0.25 to Max $1/Mile Optimize Throughput Charge Minimum to Maintain >45 MPH Charge No More Than Displayed Display Tolls First and Last Destination

4 TAS3 TAS5 TAS6 TAS2 NW 39 th St TAS4 SR 112 N Gantry 1N TAS7 TAS1 Dynamic Pricing Overview Multiple Ingress/Egress Ramps Gantries in Mainline Express Lanes Transit Times Shortest Measurable Trip GGI $1.00 GGI $1.00 GGI $1.00 N.T.S GGI $1.00 NW 10 th Ave Golden Glades Park-Ride 95 Express Lanes HOV Lane I-95 GP Lanes GGI $1.00 GGI $1.00 GGI $1.00 4

5 Dynamic Pricing Overview Algorithm Concepts Configurable parameters Updated Every 15 minutes Looks at Express Lane only Traffic Density-Based Traffic density provides the relationship among speed, volume and level of service

6 Dynamic Pricing Overview Dynamic Pricing Algorithm Parameters Delta Tables Rate of Change Level of Service (LOS) Tables Price Check Select Detectors for Calculation Detector Accuracy Monitored Performance Factor Speed Threshold for Individual Detectors

7 Dynamic Pricing Concepts Sample Toll Calculation Toll (Tt-1) = $4.00, TDt-1= 27, TDt = 29 TD of +2 Yields T of +$0.50 Tt = Tt-1 + R Tt = $ $0.50 = $4.50 Check Range in LOS Table $4.00>$4.50<$7.00 Traffic Density Level of Service Delta Table Δ Traffic Density $0.00 $0.25 $0.50 $ $0.00 $0.25 $0.50 $ $0.00 $0.25 $0.50 $ $0.00 $0.25 $0.50 $ $0.00 $0.25 $0.50 $ $0.00 $0.25 $0.50 $0.75 LOS Table Traffic Density Toll Rate Min Max A $0.25 B >11 18 $0.25 $1.50 C > $4.00 D >26 35 $4.00 $7.00 E >35 45 $5.00 $7.00 F >45 $6.00 $7.00

8 Parameter Adjustments Timeline Performance Target March 2010 August 2011 December 2012 Delta and LOS Table Recovery From Closure Increased Delta Table Range March 2014 December 2011 Increased Min and Max Tolls Delta and LOS Table February 2012 Added Performance Factor 8

9 Parameter Adjustments Phase 1B Impact Increased Max Peak Hour Flow at Ingress No Increased Capacity at Egress Reduced % speeds > 45 MPH to 80% during PM Peak Period

10 Parameter Adjustments Before Delta and LOS Adjustments (Phase 1B) Price tolerance increases based on visible speed differential Initial demand change to Tolls >$3.00 Tolls capped by LOS Table, TD continues to increase Price tolerance reached; demand decreases

11 Parameter Adjustments After Delta and LOS Adjustments (Phase 1B) Removed limit from LOS Table and Toll increases more aggressively 11

12 Closed Parameter Adjustments Before Recovery From Closure Demand remains high with TOD Tolls

13 Closed Parameter Adjustments After Recovery From Closure Tolls adjust to allow for maximizing facility throughput Closed Tolls are higher after closure; shift demand from EL to GPL

14 Parameter Adjustments Increased Min and Max Tolls Select Sample Days Max Toll Reached Develop Scenarios Variations LOS Table Back Test Changes Analyze Results Goal is to Maximize Throughput 14

15 Parameter Adjustments Increased Min and Max Tolls 15

16 Parameter Adjustments Increased Min and Max Tolls 15% drop in volume 16

17 Parameter Adjustments Increased Min and Max Tolls Performance Restored Incidents Impacting Performance 17

18 Preparing for Phase 2 Segment-Based to Trip-Based Locks in Maximum Trip Toll at Beginning of Trip Software Impacts More Challenging Operations Trip A-C Trip A-B Segment 1N Segment 2N Trip B-C Segment 3N A B C To A $2.00 To B $1.00 To C $2.00 To C $5.00 To C $3.00 Tolling Point -

19 Lessons Learned Dynamic Tolling Configurable Parameters Monitor Changes in Demand Avoid Short Segments Need Tools for Analysis Toll Amount DMS displays the toll amount for 95 Express southbound

20 Lessons Learned General Keep the Administrative Rules Flexible Involve Operations Early Concept of Operations Incident Management Take a Regional Approach Phased Implementation Develop Transition Plans Public Outreach FDOT has identified a Regional Network of Express Lanes for South Florida
