The Chicago Department of Transportation (CDOT) has introduced guidelines for Travel Demand Study and Management (TDM) Plans. These guidelines aim to reduce traffic congestion, minimize environmental impacts, encourage public transit and bike use, and decrease single-occupancy vehicle trips.

According to the Connected Communities Ordinance, new construction projects in Business (B), Commercial (C), and Downtown (D) zoning districts within a half-mile of CTA and Metra rail stations must adhere to TDM rules set by CDOT. TDM strategies are designed to manage travel demand by promoting sustainable transportation modes such as walking, cycling, and public transport. Strategies may include transit subsidies, carpooling incentives, additional on-site bike storage, and shuttle services to transit stations.

The interim guidelines were developed with the Chicago Department of Planning and Development's Zoning Division. They will serve as a basis for finalizing the rules. CDOT staff will assist each project in meeting these requirements.

Since 2013, Chicago has promoted compact, mixed-use transit-oriented development (TOD). This approach offers benefits like increased transit ridership, walkable communities, reduced traffic congestion and greenhouse gas emissions, and safer streets. Implementing TDM is a key recommendation of the Equitable Transit-Oriented Development Policy Plan. This plan aligns building design with city goals for public health, racial equity, climate action, and street safety.

TDM requirements will vary based on factors like square footage and dwelling units. The guidelines are effective immediately but will be updated as the TDM program evolves. CDOT plans to use data from annual surveys to refine these rules further before releasing them in early 2024.
