Division of Research, Innovation, and System Information (DRISI) - System Information (SI)

DRISI resulted from the merger of the two divisions: Transportation System Information (SI) and Research and Innovation. This website is devoted to SI part of DRISI. That is, mostly the documentation of what is out on the roadway and ways to access data about it. Below are our offices devoted to SI and some of the services we provide. Two of our offices Office of Data Services and Technology and Office of Highway System Information and Performance. are located at the 1120 N Street. The remaining eight offices are located at 13th/O Streets. We are currently researching ways to make the two websites come together.
