In 2003, the US Department of Homeland Security (DHS) instituted the Surface Transportation and Reliability Act, putting in place measures to identify the security needs of US roads and bridges. Funding was provided under the act for Florida Department of Transportation's iFlorida programme. The aim of the programme was to provide a transportation information infrastructure (infostructure) to demonstrate how security, reliability and safety can be enhanced through the availability of real-time information. The bridge security subproject focused on developing video/software-based detection systems for two bridges in Florida: the Jacksonville Bridge and the Orlando Area Bridge. The Security Command and Control contract was awarded to MasTec North America Inc. The detection system combined thermal and infrared technology surveying road and waterborne traffic. It combined fixed and pan-tilt-zoom (PTZ) surveillance. When an object or person is stationary for longer than a set period, an alarm is triggered. Details are given of the equipment selection for the two bridges. It included Extreme CCTV ZX55 cameras, Sensormatic Speed Dome Ultra VII CCTV cameras and ISAP POD 100 thermal cameras.
