Traffic speed sensors to be installed in Los Angeles county

SpeedInfo : 12 March, 2008  (Application Story)
Real time data collection and analysis capability added for transport planning in Ventura County in the USA using Doppler radar speed sensors provided by SpeedInfo.
SpeedInfo has deployed its real-time traffic data service in Ventura County, under contract with the Ventura County Transportation Commission (VCTC). SpeedInfo has installed 90 solar-powered Doppler radar sensors along Highways 23, 33, 126, 118 and 101 providing comprehensive traffic speed coverage for over 270 miles of roads in Ventura County.

"We reviewed proposals for multiple types of traffic information technology and determined that SpeedInfo's turn-key data service provided VCTC the most easy-to-deploy and cost effective system," said Steve DeGeorge, director of technology at VCTC. "VCTC is eager to continuously upgrade our transportation network to offer our constituents the most current and accurate traffic information, both for handling everyday traffic needs, but also to ensure safety, and to improve our ability to respond in the event of an emergency."

Real-time traffic information collected by SpeedInfo sensors will be used by VCTC to enhance local operations, improve congestion management and emergency response. The data will also be fed into the greater Los Angeles area 511 system, which will be expanded to provide real-time traffic coverage for Ventura County and will ultimately provide easily accessible information to all constituents of Ventura County.

"With deployments already in place in Los Angeles and Orange County, we are excited to provide additional sensors in Ventura County that will assist VCTC in improving and managing traffic flow along the important Highway 101 corridor and other critical arterial routes," said Doug Finlay, SpeedInfo's president and chief executive officer. "We appreciate the opportunity to support VCTC as they expand new services to their constituents and improve the flow of information on traffic conditions to all types of commuters and other travelers."

SpeedInfo's Doppler radar sensors are mounted on light or signage poles and are solar powered. 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, specialised formats. Unlike other solutions that are expensive, difficult to deploy, provide inaccurate data and/or are buried under the highway and destroyed when roads are repaved, SpeedInfo's sensors install easily. Highway crews can cover as many as 15 miles of highway a day with no lane closures or disruption to traffic
