INRIX, a provider of traffic information and intelligent driver services, has developed a US-wide archive of real-time freight traffic data.

To be available from January 2013, INRIX US Freight Traffic Profiles will cover 450,000 centreline miles and 600,000 segments across the country’s interstates, expressways, state highways and major arterial roads.

The profiles will provide transportation agencies with statistics such as average speed and travel time, percentiles, failure rate in addition to information on a number of GPS data points used to generate each result, which will be updated on a monthly basis from a real-time GPS probe data network of freight vehicles in the country.

Datasets will be obtained in 15 minute increments for every day of the week and each datasets will contain 672 specific profiles under every road segment.

"MAP-21 includes several new programmes and requirements to improve national freight movement."

The statistics archive, which will feature data from January 2010, will be used in freight system planning under the Moving Ahead for Progress in the 21st Century Act (MAP-21).

MAP-21, which has been enacted recently, includes several new programmes and requirements to improve national freight movement.

INRIX vice president and public sector general manager Rick Schuman said the service provides agencies with an important tool to move freight traffic more efficiently across the nation’s road network.

INRIX US Freight Traffic Profiles creates a nationwide, uniform and timely picture of conditions for the trucking side of freight depending on travel speeds, congestion and volumes, Schuman added.

While monthly data sets are available from January 2010, annual data sets can also be obtained for the period from 2010 to 2012.

New data sets will be made available within a 30-day period after the conclusion of the previous month.

INRIX, headquartered in the US, operates global traffic intelligence platforms and delivers smart data and analytics to the transportation industry across the world.
