  1. 2010 Traffic MonitoringWorkshop FHWA - Pooled Funds Speed Summit By: Kurt Matias February 23, 2010 kmatias@dot.state.ny.us

  2. Why Join a Pooled Fund? • Allows for larger studies • Allows for multi-State collaboration • Helps States avoid paying large amounts of money for quality research results • Facilitates improvement within the State-of-the Practice where States need it most • NY joined these studies using Research Bureau money

  3. FHWA Pooled FundNon-Intrusive Technologies Phase III • TPF – 5(171) • Began January 2009 • Lead State – Minn DOT • SRF Consulting awarded RFP bid • Current list of Study Partners: NY, CT, FL, GA, HI, IA, ID, IL, MN, MS, MT, OH, and TX

  4. NIT Phase III - Goals • Establish Ground Truth for Data Collection • Determine NIT Equipment Installation Limitations • Measure Sensor Technology Accuracies • Measure Limitations of NIT devices • Lighting • Occlusion • Weather • Improve accuracy of NIT devices

  5. NIT Phase III – Schedule • TAC Met for Kick-Off Meeting at Minn DOT – April 2009 • Ground Truthing – October 2009 • Field Work November 2009 – May 2010 • Final Report Due – June 2010 • Phase I and II Reports Available Online – • Phase I http://www.dot.state.mn.us/guidestar/1996_2000/nit1.html • Phase II http://www.dot.state.mn.us/guidestar/2001_2005/nit2.html

  6. NIT Phase III – Pooled Fund • Current Funding (limited) – $195,000 • Current list of Sensors to be included in the study: • Axle Light – Peek Traffic • TIRTL – Control Specialists Company • Wavetronix – Smart Sensor HD • Microloop – Global Traffic Technology • Mio Vision – Video Collection Unit

  7. NIT Pooled Fund in Action • Research Implementation: • Comprehensive results using the same testing methods for all sensors: • Ground truth results • Various test environments – high volume, low volume, and varied weather conditions • State DOT’s will have improved knowledge of each tested sensor and can better use each technology • Known sensor features and limitations • Improved methods for traffic data collection using NIT

  8. FHWA Pooled FundLoop/Length Based Vehicle Classification • TPF – 5(192) • Started January 2009 • Lead State – Minn DOT • Consultant Contractor – SRF Consulting • Study Partners: NY, AK, CT, FL, ID, IL, MI, MN, OH, PA, TX, WA, WI and WY

  9. L/LBVC - Goals • Establish loop specifications for optimum length based accuracy • Determine number of length bins and sizes that will work with different technologies across different States • Research Tasks: • Loop size, shape, installation techniques… • Optimization of length bins – number and vehicle size • Determine the accuracy of LBVC • Find causes of inaccuracies and methods to avoid them • Testing some non-loop based equipment

  10. L/LBVC - Schedule • TAC Met for Kick-Off Meeting at Minn DOT – April 2009 • RFP bid awarded to SRF Consultants – October 2009 • Literature review – November 2009 to May 2010 • Meeting at NATMEC – June 2010 • Field installations and data collection – 2011 • Study completed – June 2012

  11. L/LBVC - Pooled Fund • Current Funding (limited) - $425,000 • Expected Results: • Establish best loop installation practices to improve length based classification measurements • Define number of bins and the thresholds for each bin to make length based data transportable between technologies, vendors and States • Determine the length based accuracy for various technologies • Determine the criteria to obtain the best possible length based measurements

  12. L/LBVC Pooled Fund in Action • Research implementation: • Establish standard for number and size of each length bin • Determine the accuracy of length based measurements and what methods will improve results • Determine the optimum loop layout that will lead to improved accuracy and better length based data

  13. FHWASpeed Data Summit Meeting • 18 states participated: PA, GA, CA, MT, AZ, ID, OH, MN, TX, VA, IN, NY, ME, FL, WA, CO, WA, and MD • Including FHWA, CUTR, and Federal Safety folks • Summit kick-off held at CUTR in Tampa, FL on Nov. 3-4 • Discussed some states speed data programs (FL, NY, OH and PA): • Collect data by direction/lane • Binning schemes • Reporting methods

  14. Speed Summit in Action • Consensus on common database structure to collect and store speed data: • By lane • Every 15 minutes (preferred) every hour acceptable • In 5 MPH bins • First bin ≤ 20 MPH • Report in 5 MPH increments • Last bin at least 85+ MPH • Identify count location by Lat/Long

  15. Speed Data Summit • Implementation: • Draft Speed Data chapter for the TMG – February 2010 • Collect speed data from a few participating states • Continue to Develop and refine Speed Data QC checks • Add speed data requirement to TMG • TMAS (Travel Monitoring Analysis System ) 3.0 will require states submit speed data via the web to FHWA
