The Center for Advanced Transportation Technology Laboratory at the University of Maryland was originally established in 2002 as an academic applied research and development lab to support national, state, and local efforts to solve important transportation, safety, and security problems. The CATT Lab accomplishes this mission through innovative technology deployments and user-centered design of software and information visualization systems. Our work spans many disciplines including Intelligent Transportation Systems, law enforcement, network security, private business, defense and homeland security.
