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

DRISI was formed from the merging of two smaller divisions: the Divsion of Transportation System Information and the Division of Research and Innovation. Six of our offices and our Chief, Mark Samuelson, are located in the Veteran's Affairs Building on 13th and O streets while two of our offices (Office of Data Services and Technology and Office of Highway System Information and Performance.) are located at the Caltrans Headquarters building at 1120 N Street. As we merge more completely we will all be together on one website, but while we decide the best way for that to be done, we will continue with the two websites.
