TMACOG Regional ITS Architecture | (click to open)
The Toledo Metropolitan Area Regional ITS Architecture is a roadmap for the integration of transportation systems in the TMACOG region. The architecture covers a fifteen-year timeframe (2004–2019) and identifies all existing and planned information sharing (primarily electronic information sharing) related to surface transportation. The architecture represents a shared vision of how each agency’s systems will work together, sharing information and resources to provide a safer, more efficient, and more effective transportation system for travelers.

The architecture provides an overarching framework that shows how information will flow between local and state governments, public transit, emergency responders, media, the general public, and others. It includes many communication links, both existing and potential future ones. A few examples are:

• Traffic control signals and systems that "talk" to each other for better timing or to respond to changes in traffic conditions

• Traffic control signals that "talk" to the signal department, providing automatic equipment status and incident information

• Freeway and roadway monitoring systems that spot slowdowns and crashes, then alert the public, the media, and incident responders

• Communication links between public transit and the public (example, signs that give real-time bus arrival information)

• Links between public transit or school transportation systems and roadway/traffic signal maintenance departments (providing roadway condition updates)

• Traffic signal preemption systems, for example, extending green lights for emergency or transit vehicles

• Communication links between traffic agencies and major public event organizers -
  allowing appropriate traffic controls to be put in place

These are just a few of the many potential communications flows. For more details, click on the above link to the TMACOG regional architecture web page. For any questions, contact TMACOG staff.

Using the architecture, each transportation project can be viewed as an element of the overall transportation system. The architecture shows the relationship between individual transportation projects and ways to cost-effectively build an integrated transportation system over time.
