Public Transportation Providers

IDOT aims to enhance Illinois’ transportation network by providing technical assistance and financial resources to public transportation providers and rail operators. Our goal is to provide mobility options which support an interconnected transportation network that provides for the efficient movement of people and goods throughout the state.

Technical Studies

IDOT seeks to provide hands-on planning and financial help for grantees who are looking to resolve some of their public transportation and/or intermodal problems.  Public transit problems can run the gamut from reorganization of bus operations to transit-oriented development to development of specialized transit services for elderly people or people with disabilities. Intermodal issues can include the development of smart corridors or the analysis of freight traffic flows, to the development of truck parking at existing and new industrial parks.  We enjoy talking over ideas with potential applicants and welcome inquiries!


Eligible applicants are authorities of the State of Illinois, metropolitan planning organizations, and local governmental authorities, including public transit agencies.


Per 49 USC §5305, Technical studies cover the following types of studies:  “(A)  Studies related to management, planning, operations, capital requirements, and economic feasibility; (B)  Evaluation of previously financed projects; (C)  Peer reviews and exchanges of technical data, information, assistance, and related activities in support of planning and environmental analyses among metropolitan planning organizations and other transportation planners; and (D) Other similar and related activities preliminary to and in preparation for constructing, acquiring, or improving the operation of facilities and equipment.”


Technical Planning Study Reports

IDOT’s Division of Public and Intermodal Transportation funds and works with eligible Grantees on public transit and intermodal transportation planning studies. These studies cover a wide range of activities that are eligible under 49 USC §5305. They are designed to help Grantees make more informed choices when later seeking capital or operations funding.

The following studies help illustrate the variety of issues Grantees face. They include but are not limited to such issues as reorganizing existing bus operations; determining the physical, operational, and financial feasibility of rail line extensions; analyzing how elderly people make transit mode choices; and identifying major freight traffic flows within and through Northeastern Illinois.
