Architecture Scope

The scope of the Regional ITS Architecture can be described in terms of: 1) the size of the region and jurisdictions covered (geographic scope), 2) the planning or time horizon, and 3) the variety of transportation services that are covered. This scope is defined in the context of adjacent and overlapping Regional ITS Architectures.


The Northeastern Illinois Regional ITS Architecture is a roadmap for transportation systems integration in the seven county NE Illinois region over the next 15 years. The systems included in the Architecture support the goals of the region's comprehensive plan, GO TO 2040. Specifically, items are included that support the Regional Mobility recommendations, which include 1) Invest Strategically in Transportation, 2) Increase Commitment to Public Transit and 3) Create an Efficient Freight Network. The Architecture also contains the building blocks needed to implement GO TO 2040 recommendations, including: congestion pricing, modernizing the existing highway and transit system, ITS components of major capital projects, bus rapid transit and transit signal priority, and many projects which support the freight industry.  

The architecture has been developed through a cooperative effort by the region's transportation agencies, covering all modes and all roads in the region. The architecture represents a shared vision of how each agency's systems will work together in the future, sharing information and resources to provide a safer, more efficient, and more effective transportation system for travelers in the region. The architecture is an important tool that is intended to be used by 

-Planning agencies to better reflect integration opportunities and operational needs into the transportation planning process. 
-Operating agencies to recognize and plan for transportation integration opportunities in the region. 
-Other organizations and individuals that use the transportation system in the Northeastern Illinois region.
