FHWA - Pooled Funds Speed Summit By: Kurt Matias February 23, 2010

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

FHWA Pooled Fund Non-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

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

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 Phase II

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

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

FHWA Pooled Fund Loop/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

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

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

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

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

FHWA Speed 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

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

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
