Traffic Management Accomplishments and Needs Dec. 08, 2011
- 1. Traffic Management Division Accomplishments and Needs FY 2011 Rob Clayton, P.E., PTOE Traffic Management Engineer Presentation to the Transportation Commission December 8, 2011
- 2. Outline of today’s presentation • FY 2011 accomplishments - Selected completed projects - Performance measures • FY 2012 priorities • Funding needs
- 3. Selected FY 2011 completed projects • “UDOT Traffic” smartphone application • Corridor responsive ramp metering • Adaptive traffic signal control in Heber City • Numerous fiber optic connections
- 4. “UDOT Traffic” Smartphone App Trends for smartphone usage in the United States: - 35% of adults have a smartphone (72 million nationwide) - 40% of mobile phones are smartphones - Ave. data usage per user increased by 89% in the past year - Cost of data dropped 43% in the past year
- 5. “UDOT Traffic” Smartphone App - Available free for the iPhone and Droid - Contains all data available on CommuterLink and 511 - 20,000 downloads in the first week! - Preliminary feedback is very positive Trends for smartphone usage in the United States: - 35% of adults have a smartphone (72 million nationwide) - 40% of mobile phones are smartphones - Ave. data usage per user increased by 89% in the past year - Cost of data dropped 43% in the past year
- 15. “UDOT Traffic” Smartphone App
- 16. Corridor Responsive Ramp Metering What is it?
- 17. Corridor Responsive Ramp Metering How does it work? “Seattle Bottleneck Algorithm” automatically adjusts the metering rate to account for: - Mainline traffic volume at the merge - Level of mainline congestion downstream - Level of backing on the ramp
- 18. Corridor Responsive Ramp Metering Current initial deployment on I-15 in Salt Lake County: - 3300 S to 9000 S (SB) - 12300 S to 7200 S (NB) Broad implementation is in development.
- 19. Adaptive Traffic Signal System – Heber City - 5 Signals on Main Street (US-40) - runs 16 hrs/day, 7 days/wk
- 20. How does adaptive signal control work? The system monitors traffic in real-time and dynamically modifies traffic signal timing and coordination plans. SCATS Traffic data from the SCATS systemSeptePark8,City: Actual Reporter in be 00 Cycle Length On Tuesday 18 September 2007 filename:PARKCT_20070918.sm 4 - 96 sec Plan Plan 5 - 128 sec Plan 3 - 86 sec Plan 4 - 96 sec Plan 2 - 82 sec Plan 2 - 82 sec Subsystem 2 16 12 Plan
- 21. Adaptive Traffic Signal System – Heber City
- 22. Expansion of the UDOT Fiber Optic Network FY 2011 expansion through state funds and trades: - Utah State University connection - SR-30, I-15 to Logan - I-15, Perry to Idaho border - I-80, 5600 West to Wendover - SR-36, Tooele to I-80 - SR-248, Park City to US-40 - Heber City interconnect - Vernal City interconnect - US-191, Moab to I-70 - I-70, Cove Fort to Richfield - Cedar City interconnect
- 24. Support of Region projects Technical assistance on: • 4 Diverging Diamond Interchanges (DDI) • 12300 S Thru-Turn intersection • 5400 S Flex Lane project • 9 Continuous Flow Intersections (CFI) • I-15 CORE project
- 27. FY 2012 Priorities • World Class Signal Operations • Website and smartphone app personalization • Enhanced / automated information feeding 511 • Unifying CommuterLink and “Know Where, Know Why” • Software to improve efficiency in the control room • Continued expansion of the fiber optic network • VMS at the I-70 / US-6 junction • Connecting Utah County and Tooele dispatch centers • Variable speed limit pilot project in Parley’s Canyon
- 28. World Class Traffic Signal Operations John Njord: “What would it take for UDOT’s traffic signal operations to be World Class?”
- 29. World Class Traffic Signal Operations John Njord: “What would it take for UDOT’s traffic signal operations to be World Class?” What needs to change? UDOT must become proactive with signal maintenance UDOT must become proactive with signal timing
- 30. World Class Traffic Signal Operations John Njord: “What would it take for UDOT’s traffic signal operations to be World Class?” What needs to change? UDOT must become proactive with signal maintenance UDOT must become proactive with signal timing How will we accomplish these changes? Increase funding for maintenance and signal timing
- 31. The Future Adaptive Systems that adjust dynamically to changes in traffic Automation Automated collection and broadcast of travel conditions Artificial intelligence Software systems that learn and improve efficiency
- 32. Use of ITS Funding • Less emphasis on ITS hardware • More emphasis on software systems and traveler information • “Operational projects” to “Optimize Mobility”
- 33. Summary • The state funding of $3 M per year is currently adequate to address ITS priorities. • We are shifting our use of ITS funding from infrastructure to software systems projects.
