Yang Cai, systems scientist in the School of Computer Science's Human-Computer Interaction Institute, presented his research on security measures for transit systems to the technical panel of the Transportation Research Board (TRB) at the National Academy of Sciences (NAS) in Washington, D.C., on June 24. The TRB sponsors Cai's research project. TRB Program Manager Harvey Berlin said the project is a "forward-thinking study that was proposed two years before the Madrid Transit Bombing. It has alerted agencies such as the Transportation Security Administration."
Cai and his assistant, ECE senior Paul Li, are working with Richard Shnyder from the Port Authority on field testing of prototypes and proposing new technical concepts. Co-principal investigators of this project include ECE Professor and Center for Wireless and Broadband Networking Director Dan Stancil and Mel Siegel from the Robotics Institute.
The NAS is preparing a bill in Congress for continuation of funding for transit security. Currently, Cai is initiating the transit security technology consortium with industry and government. He was invited to give a talk about "Minimalism Context-Aware Displays" at the Adaptive Display SIGGRAPH conference in Los Angeles on August 7. The Army Research Laboratory sponsored his trip.
