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

Formerly TSI/ Now DRISI - HQ Location

The Division of Transportation System Information has merged with the Division of Research and Innovation (DRI) on November 1, 2012. The new division is the Division of Research, Innovation, and System Information (DRISI). We will continue to provide the same great services but under a different name. One of our offices, Office of Travel Forecasting and Analysis, will also be moving to Transportation Planning. We will try to make these changes as smoothly as possible. We will keep you posted and will try to keep you connected with your important links! Don't hesitate to call or email us if you have any questions or need assistance.
