Transit IDEA J-04/IDEA 35 [Completed (IDEA)]

Innovative Bioterrorism Detection Technology for Transit Security
[ TCRP J-04 (Innovations Deserving Exploratory Analysis--The Transit IDEA Program) ]

  Project Data
Staff Responsibility: Harvey Berlin

This project investigated the detection and identification of potential biological warfare agents in both a benign laboratory environment and a simulated subway situation, using an integrated approach involving proprietary laser technology. The objective of this project was to demonstrate that biological agents can be quickly detected and characterized in a transit environment. This would have the potential to improve security in subway systems and give an early warning to transit officials so that they could take appropriate actions quickly and effectively.
 
Completed Investigation

The investigators integrated the laser technology into a demonstration system to test the principle of biological agent detection and characterization. The system was first set up and tested in a benign laboratory environment to demonstrate the ability to detect and differentiate the samples.

The investigators procured typical subway particulate matter from a New York subway station characteristic of what would be expected in an operational transit subway station environment. They tested the ability of the system to detect and distinguish biological contaminants in the presence of field particulate matter from subway stations.

Project Results

Laboratory setup for this investigation has been completed and the investigators have received certification from the government to work with dead target organisms. A literature review of available biological agent detection technologies has also been completed.

The biological material used in the tests has been detected and researchers have been able to separate the target agent from the particulate matter collected in the subway system. Detection sensitivity limits and identification time were evaluated. The tests will allow the investigators to assess this approach for transit applications.

Project Payoff Potential

If proven successful in a transit environment, this technology has potential to detect biological threat attacks in real time, to alert appropriate officials to the nature of a specific attack,

and to identify the biological agents. Beyond specific applications to subway systems, there is potential to translate the developments designed specifically for subway transit security into other possible transit applications.

Product Transfer

New York City Transit (NYCT) participated in the project by assisting the investigators in obtaining sample particulate matter from a typical subway station and by reviewing and commenting on the technical progress of the system. A final report describes the project activities, test design, and results.
