INRIX Pioneers Another Traffic Industry First – Launches Real-Time Traffic Alerts across the Entire U.S. Interstate Highway System

MapQuest and other customers plan to alert commuters and truckers of unusual traffic congestion
on more than 100,000 miles of freeway

INRIX® today introduced Nationwide Traffic Alerts on more than 100,000 miles of major arterials, freeways and highways, including the entire U.S. Interstate Highway System, with never-before availability of real-time traffic alerts highlighting abnormal traffic congestion across the nation. MapQuest and other INRIX customers intend to deliver INRIX Nationwide Traffic Alerts for major urban, interurban and rural roadways, highlighting unusual congestion wherever it may occur across the country from a myriad of sources.

INRIX uniquely can provide this traffic information, based upon its sophisticated data fusion of real-time speed data from its exclusive Smart Dust Network of over 800,000 GPS-enabled vehicles, data collected anonymously from mobile phone devices, and traditional road sensors covering more than 9,000 miles of road. INRIX’s technology platform processes billions of data points per month and uses intelligent analytics to identify patterns of movement that help detect traffic abnormalities on roads where coverage was either limited or simply didn’t exist before.

Unlike areas with fairly comprehensive road-sensor networks such as the I-10 freeway in Los Angeles or the I-5 corridor in Seattle where traffic information is readily available, INRIX Nationwide Traffic Alerts allows the long-haul truck driver traveling on I-26 in South Carolina to receive alerts of traffic delays caused by extreme weather at the I-95 junction and choose an alternate route to avoid the congestion, greatly improving the chances of making his delivery to Columbia on time.  Similarly, the leisure traveler heading to Lake Tahoe from San Francisco for Spring break can now be alerted ahead of time when a jack-knifed 18-wheeler brings traffic to a 3-hour standstill along Highway 50. 

INRIX Nationwide Traffic Alerts represents a radical improvement in traffic information available to the two hundred million drivers in the U.S.  Websites, government agencies, automobile manufacturers, fleet management service providers, and portable navigation device makers are among the many who can benefit from INRIX’s powerful new tool.

“More and more MapQuest users are planning trips online and Nationwide Traffic Alerts will make destination planning even more convenient.  MapQuest users will be able to get information about unusual traffic congestion as it happens, as well as highway construction and planned traffic impeding events while online or have alerts sent directly to their mobile devices,” said Christian Dwyer, Senior Vice President and General Manager of MapQuest.  “INRIX continues to innovate and is commited to providing the most comprehensive set of traffic data in the U.S.”

INRIX’s Nationwide Traffic Alerts is different than anything else on the market today. Traffic data is generated by INRIX’s award-winning Smart Dust Network, which fuses together the most comprehensive amount of traffic information available anywhere – collecting data anonymously every minute or two from vehicles across the country which automatically send their position and speed back to the INRIX Operations Center.  The INRIX Fusion Engine then blends this information together with real-time data from dozens of other sources such as real-time incident data, construction data and events and then delivers real-time information regarding current road speeds to INRIX customers. That way, INRIX customers always have the best, most up-to-date traffic available.  The result is real-time traffic speed and flow information on more than 55,000 miles in 106 metropolitan areas today, plus more than 2500 alerts per day on the additional 45,000 roadway miles in urban and interurban areas which have limited or non-existent traditional road sensors. Alerts are automatically created as individual incident messages alerting drivers to roads that are experiencing abnormal traffic congestion at that time of day.

“The majority of traffic information available today is only for a limited set of roads in major urban areas,” said Bryan Mistele, president and CEO of INRIX. “This is the first time that consumers and businesses have access to traffic congestion data across our country’s interstates.  INRIX uniquely is able to deliver this solution by leveraging our exclusive strategic relationships with national and regional fleets, relationships that provide us mobile-phone based data, and smartly applying our technology to solve complex problems.”

INRIX Nationwide Traffic Alerts

What are INRIX Nationwide Traffic Alerts and why is this announcement important?

  • The INRIX Nationwide Traffic Alerts service provides real-time traffic alerts for over 100,000 miles of freeways, highways and major arterials across the entire US. Alerts are reported by INRIX for road segments (at the TMC code level) which have unusual or abnormal -- “stop and go” or “severely congested” -- traffic flow conditions.
  • INRIX is the only traffic data provider that can provide this type of coverage on this many miles of roads (over 100,000 across the US). INRIX is able to provide these alerts based upon its sophisticated data fusion of real-time speed data from its exclusive Smart Dust Network of over 800,000 GPS-enabled vehicles, data collected anonymously from mobile phone devices, and traditional road sensors covering more than 9,000 miles of road.
  • Until now, traffic information (from any provider) has been very metro-focused. By adding Nationwide Traffic Alerts across major highways, arterials and rural thoroughfares, INRIX is effectively “stitching together” the entire roadway system in the US, making this valuable information available to travelers and fleets.
  • The alerts for 100,000 miles are based on INRIX’s current real-time traffic flow coverage of 55,000 miles in over 100 metropolitan areas plus an additional 45,000 roadway miles in urban and interurban areas which have no or limited traditional road sensors. Alerts are created on roads experiencing abnormal traffic at that time of day.
  • MapQuest recently went live with INRIX Traffic on MapQuest.com and their MapQuest Mobile Navigator solution. MapQuest plans to roll out additional innovative INRIX traffic-enabled solutions including leveraging INRIX Nationwide Traffic Alerts in the future.

New INRIX White Paper Available
Measuring the Accuracy of Traffic Flow Information

Best Practices in Ground Truth Testing Methodologies & Analysis

Where the rubber hits the road for real-time traffic information is in measuring its quality.  There are many difficulties associated with doing so, compounded by the distinction between the ‘out-of-the-window’ experience of a consumer or single vehicle and the average experience over extended components of space and time which traffic flow information is designed to reflect.  The most pronounced difficulty lies in the use of single or few vehicles to measure, or more realistically, corroborate the estimate of traffic flow conditions that a provider is transmitting. 

At INRIX we subject our traffic data to a rigorous regime of testing, including:

  • Statistical tests in real-time of the estimated accuracy of every data value that we transmit.
  • Low vehicle count drive-testing of data quality in our major markets.
  • High vehicle density third-party drive-testing and competitive evaluation.
  • Testing of Real-Time, Predictive and Historical data products.

In this detailed whitepaper we describe considerations for the planning and execution of ground truth testing of traffic flow data, and describe INRIX-supported best-practices for ground truth testing, as a guide for customers and partners.

If you are considering any kind of ground truth testing, this white paper is a must read!
