The appendices

The nine appendices provide deeper detail on topics ranging from administrative policies and air quality conformity to the financial plan and public engagement.

The policy briefs

The RTP’s policy briefs explore emerging issues and policy contexts that helped inform the plan’s recommendations. Four briefs focus on broad transportation topics: emerging technologies, intercity rail and bus, asset management, and innovative financing and project delivery. Three additional briefs examine transportation funding in greater detail, including potential revenue sources, tolling and pricing strategies, and a road usage charge in Illinois. Together, these resources provide a closer look at both the RTP’s financial foundation and the policy questions northeastern Illinois will need to navigate as the plan is implemented.

Additional reports and supporting work

As the RTP was developed, a series of reports documented emerging priorities, recent trends, and existing conditions to help inform the plan’s goals, objectives, and strategies. During RTP development, CMAP also updated its federally required congestion management process — producing an updated framework and complementary resources to mitigate congestion in northeastern Illinois.
