CCTV for Bridges
Among the greatest achievements of human civilization are bridges. bridges have served as lifelines, while that inspires the imagination of people since early primitive structures where logs are placed on streams simply extends the long, arched civilization Rome, which still stand today, the modern engineering masterpiece.
Bridges enable communication and transportation in times of peace. Furthermore, bridges, acquire a strategic value in times of war. The destruction of bridges has greatly contributed to the result of armed conflict throughout history.
A more sinister new kind of war was revealed through America on 9 / 11 attacks. Bridges play a critical role in defense strategies in times of war. Hundreds or thousands of casualties, billions of dollars in direct reconstruction costs and even greater socio-economic costs may occur with the destruction of a bridge critical or a tunnel in one of the many bottlenecks in the system of roads.
The report released by the White House in February 2003, entitled " National Strategy for the Physical Protection of infrastructure and key assets, "said the close relationship between the many segments of the economy and the country's transport infrastructure. Transport and almost all other sectors of the economy have always been and will continue to depend on each other in many respects. As a result, Threats to affect transport operations to other industries who rely on it.
A terrorist attack on any of the criticism about a thousand bridges in the United States may result in substantial casualties, economic disruption and other ramifications of society, as reported by a study by post-9/11 Science Applications International Corp. A real life example was the path commuter rail line in New York, which was not working after the attacks 9 / 11. The closure of this line more than 67,000 passengers affected for over two years. Not only that, but it also contributed to the relocation more than one hundred companies, 1.1 million square feet of office space and 11,700 jobs to New Jersey. These results devastating example of socio-economic loss a transportation route.
Similarly, the road infrastructure has vulnerabilities that must be addressed as noted a 2003 FHWA document entitled "Recommendations for Bridge and Tunnel Security. "This issue is so crucial that many people would like the word, between national security policies. Improvements in security interior improvements must address vital bridges and tunnels.
The Coming of Homeland Security
The vanguard of the infrastructure road saw little change until the Department of Homeland Security began the surface transportation and Reliability Act in 2003. Moreover since the time change unprecedented political, DHS has taken extensive measures to identify the security needs of the U.S. highway infrastructure, including more than six hundred thousand bridges located throughout the U.S..
March 2003 was the moment when the first milestone in the development process was carried out, this was the time when the DHS issued a four-year, $ 10 million award to match the administration of the Federal Highway Department. The main reason for this grant was designed to develop the security model related facilities in several target areas, one of which deals with finding the best approach to implement a network of safety of the bridge.
As a result, the FHWA, state departments of transportation allowed to recommend projects to win the award and for the first time in history, gave him all the grant to a single bidder who was the Florida Department of Transportation and its value offering for the project IFLOR.
According to a manager IFLOR program the primary mission of the installation IFLOR model is to provide a transportation information infrastructure (infostructure O) to show how safety, security and reliability can be improved by the wide use of real time data. The 'I' in IFLOR resembles the four objectives of the program it is about information, intelligence, infrastructure and innovation, while "infostructure" is a term that combines the information and infrastructure to improve communications and security functionality.
Security and Management Control
Security Command and Control is the name of security of the bridge model sub-project, focuses on developing video or recognition of software based systems two critical bridges in Florida, one in the Jacksonville area and one in Orlando.
According to another project manager, the main objectives for video based configuration software and recognition are to allow the detection of potential safety problems, aid in disaster prevention-related occurrences improve post-event analysis, and law enforcement in the verification of suspected hit and run through images captured by security cameras.
FDOT received the Security Command and Control contract to MasTec North America Inc. after realizing they had a clear idea of what they wanted and best way to help them achieve their goals. MasTec Director Intelligent Transport Systems sector turned security consultant for guidance in the specification and engineering metrics to assist with deployment plans.
The integration approach is one of the innovative aspects of the Security Command and Control System. The detection system is video / software-based technology includes thermal and infrared active to provide 360 degree surveillance of both boats and related with automobile traffic for most of the time of its operation. PTZ cameras, still cameras, and infrared illuminators be installed to monitor specific areas, while images from the cameras is monitored in real time in the traffic control departments. In the instant that a suspicious object or potential offender is detained beyond a predetermined period of time, an alarm, video screens and monitors TMC operators are attentive to the possible problem. Through the use of PTZ cameras, TMC operators constant monitoring of bridges and respond to alarm zones fire.
DVR video capture field locations captured by cameras at a given time. The streaming video is sent back through a fiber infrastructure Optical follow up to redundancy separate TMC and maintain local registration procedure. Once an alarm is activated in the TMC DVR begin the process of recording. The Bridges of Jacksonville and Orlando are supervised by the operators, both TMC and by the Florida Highway officers.
According to a manager of the proposed approach allows redundancy, which is very beneficial if the material is locally destroyed or removed from the TMC network.
The sites selected for this case study are intentionally different but both bridges of the main channels of watercourses. For example, the Bridge of Jacksonville is particularly urban steps slope and major intersections to keep in mind. On the other hand, the bridge of the Orlando area is clearly rural, and most of the traffic below is related to ships. As a result, the selection of equipment and safety goals for the two bridges vary considerably.
