Roadway Information Manual

This Roadway Information Manual describes information collected and managed in Ohio Department of Transportation’s Roadway Information System (RIS) that is maintained by the Transportation Information Management Section of the Office of Technical Services. The characteristics that serve to define the roadway are comprised of components referred to as Events and Attributes. These and other terms used in the Manual are described later in this document and defined in the Glossary. The Office of Technical Services is generally responsible for the methodology involving collection, processing, storage, and quality of the various roadway data elements.
