Data Driven Decisions for Capacity Projects
The Illinois Department of Transportation is in the process of developing the Data-Driven Decisions tool, allowing us to improve how we determine investment decisions for capacity projects throughout the State. The concept of Data-Driven Decisions for project selection is used throughout the nation and encouraged by the U.S Department of Transportation. The Department evaluated 34 projects for inclusion in the State Fiscal Year 2023-2028 Highway Improvement Program. A cover memo is provided explanation of the selections.
Illinois is the 5 th largest economy in the nation, by GDP, and that prosperity would not be possible without our vast transportation network. For more information please visit our network overview page.
Key Transportation Metrics
Transportation Funding
Funding for IDOT projects comes from multiple sources including:
- Rebuild Illinois
- Motor Fuel Tax (MFT)
- Portion of the Motor Vehicle Registration (MVR)
- Federal Funding
The majority of these funds are allocated toward system maintenance projects. Remaining funds can then be allocated toward expansion, capacity, or other types of projects. IDOT strives to use all available funding as efficiently as possible, keeping our vital transportation network running.
