Much of ODOT's roadway transportation system data can be found in the Integrated Transportation Information System (ITIS)
database. ITIS contains descriptive information about Oregon's transportation infrastructure, and is the official source of milepoint information.
Some of the information and reports available form ITIS are now more easily accessed through the ODOT internet. TransViewer
is a computer application that allows ODOT employees to access transportation data and information from their desktop computer.
