SpeedInfo Sensors Helps North Carolina Add New Traffic Intelligence to I-95 and I-40 Corridor SmartLink Systems

SAN JOSE, Calif.--(BUSINESS WIRE)--SpeedInfo Inc., provider of the most accurate and lowest cost solution for directly measuring traffic flow, announced today that the North Carolina Department of Transportation (DOT) has increased its deployment of SpeedInfo DVSS-100 solar-powered Doppler radar sensors. SpeedInfo and PBS&J, a leading infrastructure planning, engineering and construction management firm, worked closely with the NCDOT to deploy a total of 92 sensors to measure traffic speeds on Raleigh-Durham interstate highways and state routes.

Data from these sensors is used to provide flow data and travel times for North Carolina’s SMARTLINK 511 traveler information system and improved coverage for the Clayton bypass construction and support arterials. SpeedInfo sensors provide traffic information on the congested I-40, I-540 and I-95 corridors, covering approximately 300 miles of roadway. The sensors enable NCDOT to monitor Raleigh-Durham commuting corridors and better manage the effects of metropolitan area highway construction on traffic to the surrounding communities.

In 2006, SpeedInfo and PBS&J worked with NCDOT to deploy 40 sensors on the I-40 Raleigh-Durham commuting corridor and along I-95 to the Virginia border. This first deployment improved the coverage, quality and reliability of data for NCDOT’s Statewide Traveler Information Management System. Last month and in 2007, SpeedInfo and PBS&J deployed an additional 52 sensors.

“A wide range of government agencies and for-profit organizations are turning to SpeedInfo’s real-time traffic information solution, recognizing the accuracy of our data and the cost effectiveness of our approach,” said Doug Finlay, president and CEO of SpeedInfo. “They have found that our combination of solar-powered Doppler radar sensors, server technology and network expertise provides the best system available.”

How SpeedInfo’s Technology Works

SpeedInfo’s Doppler radar sensors are mounted on light or signage poles. Sensors are located approximately every mile and collect traffic speed information continuously. Sensors forward data to the SpeedInfo Traffic Data Server via the AT&T Wireless^® data network with virtually no latency. SpeedInfo servers format the data for delivery to customers via the Internet. The data is available from SpeedInfo servers in a standard XML format, or if required, specialized formats. Unlike other solutions that are expensive, difficult to deploy, and provide inaccurate data, SpeedInfo’s sensors install easily on existing infrastructure. Highway crews can cover as many as 15 miles of highway a day with no lane closures or disruption to traffic.
