8. Center on Tolling Research Technology for Pricing Radio Frequency Identification  Different protocols  Changes in form factor Video Imaging  For enforcement  For tolling Global Positioning Systems 5.9 GHz Dedicated Short Range Communication

9. Center on Tolling Research Presentation Outline Define Managed Lanes Technology for Management  Pricing  Access  Occupancy Technology for Operations Technology for Policy Summary

10. Center on Tolling Research Technology for Access Types of technologies  Gates  Movable Barriers  Ramp meters  Dynamic message signs Integration with ITS  Central monitoring  Central control

11. Center on Tolling Research Presentation Outline Define Managed Lanes Technology for Management  Pricing  Access  Occupancy Technology for Operations Technology for Policy Summary

12. Center on Tolling Research Vehicle Occupancy User must “declare” their occupancy Occupancy requirements can change:  by time of day  by facility  by access point User may change occupancy by trip Managing Occupancy = Enforcement Occupancy enforcement poses challenge to revenue leakage

13. Center on Tolling Research Automated Vehicle Occupancy Verification HOV Pooled Fund Study  In-vehicle systems  Weight sensors  Electrical field sensors  Monocular vision  3D Time of flight

14. Center on Tolling Research Occupancy Enforcement Roadside Systems  Video Imaging  Microwave  Ultrawideband radar  Infrared Technology  Single-band  Multi-band

15. Center on Tolling Research Enforcement Assistance Technology

16. Center on Tolling Research HOV SOV HOV Declaration Lanes Driver must declare HOV or SOV by lane selection HOV’s on outside help enforcement and accuracy of tag readers Passing would be prohibited at gantry No additional tag technology Tolling Gantry

18. Center on Tolling Research Traffic Management Technology Existing Traffic Management Technology

19. Center on Tolling Research Presentation Outline Define Managed Lanes Technology for Management  Pricing  Access  Occupancy Technology for Operations Technology for Policy Summary

20. Center on Tolling Research Managed Lane Policy High-occupancy vehicles of two or more occupants will receive a 50 percent discount during the peak period  Not just as easy as SOV pay and HOV free  More complex for different prices for SOV, HOV2, HOV3+

21. Center on Tolling Research Managed Lane Policy (cont.) Market-based tolls will be applied during the dynamic-pricing phase  Market-based pricing  No caps  Give operator ability to maintain desired operating speed  Dynamic pricing  San Diego and Minneapolis currently have dynamic pricing  Technology to gather managed lane and general purpose lane conditions

22. Center on Tolling Research Managed Lane Policy (cont.) During the dynamic-pricing phase, travelers will receive rebates if the average speed drops below 35 mph (fault of the operator)  What or how much is the rebate?  Delivered to individuals, the project, or the region?  Based on individual or average speeds?  Delivered in real-time or post trip?

23. Center on Tolling Research Summary Managed lanes will increasingly be used as a corridor management tool Technology is critical to all aspects of managed lanes  Variability in pricing & occupancy pose the biggest challenges Continue to Build on Current Technology Industry Needs Cost Effective Occupancy Enforcement
