  1. Technology for Managed Lanes Christopher Poe, Ph.D., P.E. Assistant Agency Director Director, Center on Tolling Research Texas Transportation Institute ITS America Annual Meeting Palm Springs, California June 5, 2007

  2. Presentation Outline • Define Managed Lanes • Technology for Management • Technology for Operations • Technology for Policy • Summary

  3. What are Managed Lanes? • A facility that increases freeway efficiency by packaging various operational and design actions

  4. Examples of Managed Lanes • SR 91, Orange County, California • I-15, San Diego, California

  5. Examples of Managed Lanes • I-10 & US 290, Houston, Texas • I-394, Minneapolis, Minnesota

  6. Convergence of Technology

  7. Presentation Outline • Define Managed Lanes • Technology for Management • Pricing • Access • Occupancy • Technology for Operations • Technology for Policy • Summary

  8. 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. Presentation Outline • Define Managed Lanes • Technology for Management • Pricing • Access • Occupancy • Technology for Operations • Technology for Policy • Summary

  10. Technology for Access • Types of technologies • Gates • Movable Barriers • Ramp meters • Dynamic message signs • Integration with ITS • Central monitoring • Central control

  11. Presentation Outline • Define Managed Lanes • Technology for Management • Pricing • Access • Occupancy • Technology for Operations • Technology for Policy • Summary

  12. 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. Automated Vehicle Occupancy Verification • HOV Pooled Fund Study • In-vehicle systems • Weight sensors • Electrical field sensors • Monocular vision • 3D Time of flight

  14. Occupancy Enforcement • Roadside Systems • Video Imaging • Microwave • Ultrawideband radar • Infrared Technology • Single-band • Multi-band

  15. Enforcement Assistance Technology

  16. 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 HOV Declaration Lanes Tolling Gantry HOV SOV SOV HOV

  17. Presentation Outline • Define Managed Lanes • Technology for Management • Pricing • Access • Occupancy • Technology for Operations • Technology for Policy • Summary

  18. Traffic Management Technology • Existing Traffic Management Technology

  19. Presentation Outline • Define Managed Lanes • Technology for Management • Pricing • Access • Occupancy • Technology for Operations • Technology for Policy • Summary

  20. 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. 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. 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. 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
