The CATT Laboratory at the University of Maryland has been developing the Regional Integrated Transportation Information System (RITIS) over the past decade, beginning with the Washington, D.C. metropolitan area and expanding to cover states along the East Coast. RITIS incorporates data from several types of sources including transit AVL, traffic cameras, crash data, emergency responder dispatch, and weather information. These data come from several agencies and in unstandardized formats across systems. RITIS standardizes the raw data from the various agencies and displays it through multiple visualization tools in order to allow participating agencies to improve incident response, as well as traveler information.
