Intelligent Transportation Systems

In 2005, as part of a requirement to the Transportation Equity Act for the 21st Century (TEA-21), MACOG developed a Regional ITS Plan and Architecture.  

What is ITS?

ITS improves transportation safety and mobility and enhances productivity through the use of advanced communications technologies. - US DOT

Intelligent transportation systems (ITS) encompass a broad range of wireless and wire line communications-based information and electronics technologies.  When integrated into the transportation system's infrastructure, and in vehicles themselves, these technologies relieve congestion, improve safety and enhance American productivity.  - US DOT

Essentially, ITS is using technology to make multi-modal transportation safer and more efficient for the traveling public, emergency responders and transportation planners.  MACOG has worked with jurisdictions and agencies in three counties (Elkhart, Marshall and St. Joseph) to develop an ITS Architecture database that shows the communications flows between different departments, jurisdictions, remote equipment, and travelers. One goal of the ITS Plan is to improve communication between and to the various stakeholders by using technology to improve what and how communication happens in our Region.

Examples of ITS Technologies
Traffic accidents and congestion take a heavy toll in lives, lost productivity, and wasted energy. ITS enables people and goods to move more safely and efficiently through a state-of-the-art, multi-modal transportation system.  Listed below are several ITS technologies that are being used throughout our region, in neighboring cities and states and throughout the world.
