Northeastern Illinois Regional ITS Architecture Home Page

ITS ImageThe Northeastern Illinois Regional ITS Architecture is a roadmap for intelligent transportation systems integration in the 7 county (Cook, DuPage, Kane, Kendall, Lake, McHenry, and Will and a portion of Grundy) Northeastern Illinois region over the next 15 years. 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 contained on this website has been developed from existing architecture documentation such as the GCM Architecture and the Tier 2 Regional ITS Architecture. The most recent update to the architecture occurred in November, 2007. 

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.

The architecture provides an overarching framework that spans all of these organizations and individual transportation projects. Using the architecture, each transportation project can be viewed as an element of the overall intelligent transportation system, providing visibility into the relationship between individual ITS projects and ways to cost-effectively build an integrated transportation system over time.

Time Horizon and Services

This regional ITS architecture has a time horizon of up to fifteen years with particular focus on those systems and interfaces that are likely to be implemented in the next ten years. The architecture covers the broad spectrum of Intelligent Transportation Systems, including Traffic Management, Transit Management, Traveler Information, Maintenance and Construction, Emergency Management, Vehicle Safety, Commercial Vehicle Operations, and Archived Data Management over this time horizon.

About this Web Site

The purpose of this regional ITS architecture web site is to encourage use of the regional ITS architecture and gather feedback so that the architecture is used and continues to reflect the intelligent transportation system vision for the region. The menu bar at top provides access to the stakeholders, the transportation systems in the region (the "Inventory"), the transportation services that will be provided, transportation-related functions that are envisioned, and the existing and planned interfaces in the region. To recommend changes to the architecture, please download and complete an architecture Change Request Form.
