Component

Highways, and the bridges and tunnels that connected them, carry a majority of the traffic for goods and passengers in the United States. Even small transportation incidents have proven to cause delays and shutdowns of vital routes in the past. Recently, the possibility of threats to bridges and tunnels from aircraft, personnel, watercraft, swimmers, and ground vehicles has become increasingly apparent. This study addresses the application of remotely sensed information for assessment and understanding of bridge condition and security risk characterization. A variety of sensor systems including high resolution panchromatic and multi-spectral satellite and airborne imagery will be reviewed for characterization of activity on and around a bridge structure. Ground based and airborne light imaging radar will be presented as a tool for remote definition of structural detail and understanding of changes that may represent security and safety risks for bridges. Biometric technologies will be explored for location and identification of unauthorized individuals in critical areas of the bridge structure. The objective is to provide to decision makers an integrated single view of the bridge and tunnel system risk situation.
