Intelligent Transportation Systems
(ITS) are a collection
of interconnected technologies used to collect and
distribute information about the roadway to commuters
so they can make better choices about their route and
respond accordingly to changing roadway conditions
such as traffic, accidents, and weather.

state level. In Montgomery County, this is done out of
