Caltrans Installs Solar-powered Radar Sensors

Posted by Sam Churchill on

New SpeedInfo solar-powered Doppler radar sensors along 25 miles of busy Highway 101 around Ventura County, will extends Real-Time Traveler Information from Los Angeles to Santa Barbara. Caltrans says this latest installment of sensors adds to the existing Ventura County network that provides coverage for over 150 miles of roadways in the region.

Real-time traffic information provided by these sensors will feed into the Greater Los Angeles Area’s 511Traveler Information System currently under development.

SpeedInfo sensors update real-time traffic systems with speeds every minute and are located approximately every mile. The sensors forward data to the SpeedInfo Traffic Data Server via the AT&T Wireless data network. SpeedInfo servers format the data for delivery to customers via the Internet.

Unlike other solutions, like magnetic loops that 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.

“We have continued to deploy SpeedInfo sensors over the last year to cover Highway 101 the entire distance from Goleta to the Los Angeles County line, an essential but especially congested route for business and recreational travelers,” said Steve DeGeorge, Director of Technology for the Ventura County Transportation Commission. It allows transportation agencies and travelers to see real-time highway status and identify and address specific congestion areas (commuter maps).

SpeedInfo is headquartered in San Jose. Its customers also include mass media organizations that provide traffic information that radio and television networks and mobile application developers, such as content providers for automotive navigation systems.

Caltrans manages more than 45,000 miles of California’s highway and freeway lanes, provides inter-city rail services, permits more than 400 public-use airports and special-use hospital heliports, and works with local agencies.

In other news, AT&T Government Solutions announced today three awards potentially worth up to $50 million from the Federal Emergency Management Agency (FEMA), to provide voice and data devices for the nationwide FEMA workforce. AT&T Government Solutions will serve as the primary wireless provider to FEMA and deliver wireless data and voice communications. FEMA will receive a combination of AT&T’s LaptopConnect wireless cards and BlackBerry® 8820 smartphones, as well as Push To Talk capability.
