Rick Schuman, INRIX vice president of public sector, is the author of the INRIX National Traffic Scorecard and the driver behind the primary analysis of the metropolitan and bottleneck data.

INRIX historically works with data providers, technology partners, experts and our customers to address traffic issues in North America and Europe. Collaborating to create unique and important products has been key to INRIX’s success. This Scorecard is no different. INRIX would like to thank several organizations and individuals who have assisted in one way or another in creating the Scorecard. Tim Lomax and Shawn Turner of the Texas Transportation Institute, Rich Margiotta of Cambridge Systematics and Mark Hallenbeck of the University of Washington aided in development of the methodology used. Kevin Loftus of INRIX’s partner Clear Channel Total Traffic Network provided local market knowledge and assistance. Tele Atlas supplied digital maps and TMC location reference tables allowing for our detailed road segment based analysis.

Future Updates
With access to the nation’s most detailed data on traffic conditions continuing to grow and expand, INRIX is committed to continuing to publish this summary report at least semi-annually. Based on input and feedback, INRIX will improve and expand the report in areas such as additional road coverage (the interstate network, arterials, additional metropolitan areas, etc.) or adding metrics, such as travel reliability. There are many possible extensions and expansions to the information provided in this report. We welcome inquiries from public agencies and transportation data analysts to conduct more in-depth regional or national analyses based upon our traffic data archive and look forward to partnering to tap local knowledge and domain expertise to take full advantage of our data, and to incorporate and correlate with additional data sets (i.e., construction, incidents, weather, etc.). INRIX will update this report periodically leveraging the industry’s most robust historical traffic data warehouse and welcomes feedback and suggestions for refinements and improvements in future reports.
