Transportation Management

IDOT oversees all modes – roads, railways, public transportation, and air – with the same quality and concern. The department is responsible for building and maintaining the state’s highways, regulating and supervising all Illinois airport activity, overseeing the state and federal funding for public transportation, and overseeing passenger and freight rail projects.

Through effective planning, programming, and project development efforts, IDOT strives to look at a full range of transportation options, evaluate how they affect mobility for users, assess the current infrastructure, prioritize needed improvements based on system performance and demographics, and then, with available revenue sources, integrate them into the overall IDOT transportation strategy.
