The Regional Integrated Transportation Information System (RITIS) is an automated data sharing, dissemination, and archiving.  RITIS improves transportation efficiency, safety, and security through the integration of existing transit and transportation management data in Virginia, Maryland, and Washington D.C. The emphasis of RITIS is on data fusion and standardization, and their relationship to data collection, regional transportation systems management, regional traveler information dissemination, and system evaluation. RITIS automatically fuses, translates, and standardizes data obtained from multiple agencies in the region in order to provide an enhanced overall view of the region’s transportation network. Participating agencies are able to view regional traffic information and use it to improve their operations and emergency preparedness. RITIS uses regional standardized data to enable traveler information, including web sites, paging systems, and 511. The two main RITIS functions include—the real-time fusion and exchange of regional transportation data; and data archiving.
