California Partners for Advanced Transportation Technology

The Mobile Surveillance and Wireless Communication Systems Field Operational Test (FOT) evaluated the performance of wireless traffic detection and communications systems in areas where permanent detectors, electrical power, and landline communications were not available. The FOT partners designed and built six surveillance and three ramp meter trailers, a video and data retransmission or relay site, and video and data reception facilities at the Caltrans District 12 and Anaheim Traffic Management Center (TMCs) and the University of California at Irvine Institute of Transportation Studies(UCI-ITS) Laboratory.  The system was evaluated in two different types of tests.  The Anaheim Special Event Test assessed the surveillance trailers in an application that transmitted video imagery in support of arterial traffic control during a special event. The Interstate-5 (I-5) Test examined the use of the mobile surveillance and ramp meter trailers to transmit video imagery and data in support of freeway ramp metering.
