DRISI Transportation System Information

DRISI - Transportation System Information (SI) collects and analyzes report statistics related to the fiscal status, physical and geometric extent, performance, and designation of the State's roadway systems. We then research and provide ways in which our customers can access, display, and use these statistics.

We have several offices devoted to SI and the services we provide. The Office of Data Services and Technology (ODST) and the Office of Highway System Information and Performance (OHSIP) are located at the 1120 N Street.
