Our Vision:

As the "Pathway to Information", the Division of Transportation System Information (TSI) collects, maintains, and analyzes information reflecting the characteristics of the State's public road system (including non State highways).

Our Mission:

The Division and its partners access transportation information from a linked database system; make intelligent transportation decisions using Geospatial Information System (GIS) technology; and use state-of-the-art modeling tools and information systems to support the Department's planning and project development needs.

Our Offices:

Office of Geospatial Information Systems (OGIS)

Office of Performance Measures and Data Analysis (OPMDA)

Office of Travel Forecasting and Analysis (OTFA)
