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 ...

This was a real world application of the subjects and technologies used in the class room for storm water management and planning. Within Arlington County there is an enhanced awareness of the potential to restore urban watersheds through the application of low impact development (LID) and best management practices (BMP). Some of these options include localized use of small-scale bioretention systems, rain barrels, permeable paving, rainwater collection, and vegetated roofs and incremental impervious cover reduction. To understand the potential for LID and BMP applications current condition and location of impervious surfaces in a watershed is necessary. This study collected imagery and conducted data analysis on the Little Pimmit Run watershed as part of a flood control project. High resolution airborne photography was collected during the spring of 2007. The photographic data was converted to digital imagery, geo-rectified, boundary corrected and translated into polygon data for entry into a Geographic Information System (GIS) data management system. Seven impervious surface land use characteristics were selected for evaluation. They included roofs, alleys, handicap ramps, driveways, paved medians, road ways, sidewalks and parking lots. The total impervious surface area in the watershed was determined to be 36.11% of total area. These findings are being used for exploring LID and BMP options that will have the best potential for application in this watershed.

Current practices and trends in the building material waste management area are examined from a building life cycle standpoint or cradle to reincarnation concept. Strategies include zero waste, integrated recycling, international approaches, reuse of materials, resource optimisation, waste reduction, and deconstruction. Examination of the waste management hierarchy and life cycle management of material is used to improve the understanding of reuse and recycle opportunities. Other considerations include cost, economic factors, social factors and environmental factors. All of these assessments are needed to develop a comprehensive waste management plan for a specific project. Four case studies are also presented to illustrate the benefits that can be derived from effective building material reuse and recycle.

The LID project components are an integrated storm water management approach using LID techniques to retrofit a mixed use, high density area and a decentralized wastewater treatment system. LID techniques can be simple, but cost effective instead of depending on expensive, and complicated collection, conveyance, storage and treatment systems. The LID techniques used in this project are bioretention cells, grass swales, rain barrels/cisterns, green roofs, Bayscaping, and permeable pavements. LID techniques can also play an important role in Smart Growth, Green Infrastructure, and Land Use Planning. The implementation of these techniques will reduce water consumption, runoff , and non-point sources.

The opportunities for information systems leveraging geospatial and other data sources are presented. Remote sensing imaging and non-imaging sources of information are explored. Coordination and sharing of in information is explored to improve the ability of multiple organizations to more effectively manage and respond to disasters and infrastructure condition assessment issues. These include 3-D visualization, thermal infrared imagery, LIDAR data systems, IKONOS one-meter panchromatic imagery, SPOT imagery and the use of digital aerial imagery. The general area of disaster response management is also addressed and the findings of various studies in this area are summarized. Recommendations for the use of information systems and geospatial sensors and products in the future for transportation infrastructure conditio...

Once the CIR photos are obtained by flying a small commercial plane with a recording device, experienced analysts using the remote sensed data, GPS and GIS can identify and geo-reference the failed systems. Investigations show this approach reduces time, labor, and materials for identifying septic system failures.

The laboratory is operated as a joint program with America-On-Line and George Washington University. The program is described with illustrations and discussion of the systems that are part of the laboratory. The concept of application for face recognition systems in the intelligent home of the future is presented and some initial approaches in using biometrics are shown. Issues of privacy and sharing of information within and outside the home are addressed. Issues include safety and security concerns vs. inappropriate observations of activities in and outside the home. Technology options currently available for application in the home are described and assessed.
