INRIX Traffic Data Critical in Identifying and Ranking of 100 Most Congested Road Corridors in Texas

Kirkland, WA, September 1, 2010 – INRIX®, a leading provider of traffic information and driver services, announced today that the Texas Transportation Institute (TTI) utilized INRIX traffic information in a study representing the most comprehensive analysis to date of the traffic congestion problems facing the state of Texas. The results of the 100 Most Congested Road Sections in Texas study were announced today by the Texas Department of Transportation (TxDOT).

Utilizing a new report methodology, TTI combined TxDOT’s roadway inventory and traffic volume data with statewide historical speed data from INRIX to produce the study. TxDOT’s 100 Most Congested Road Sections is a state legislative-mandate established in 2009 to identify, quantify and share with the public the most congested locations in Texas. Complete details of the report, including the 100 worst congested corridors, are located on the TxDOT website at http://www.txdot.gov/. The information released today is an update and significant improvement of the first version released a year ago.
“One of the unique elements of the 100 most congested sections list is the integration of INRIX historical traffic speed data with public agency traffic count data. This combination presents a more accurate and detailed view of traffic conditions than the estimated traffic speeds used last year,” stated Tim Lomax, TTI Research Engineer and co-author of TTI’s annual Urban Mobility Report. “In addition to congestion levels changing due to the completion of large projects and the economy causing changes in traffic patterns, the new data has provided a much better picture of congestion on Texas roadways.”

“In addition to being a great way to show the traveling public how problem areas compare across Texas, TxDOT uses this report to communicate the efforts underway to improve these key chokepoints,” said Rick Schuman, INRIX Vice President of Public Sector. “In fact, in June, 2010, the Texas Transportation Commission approved $150 million from a recent bond program specifically to develop future projects on these most congested corridors. What better illustration of the power of performance measurement that within 18 months of the passage of Rider 56, Texas officials are allocating significant resources targeted for improving system performance.”
