intelligent roadways.

Today's roadway transportation infrastructure increasingly uses technology to manage traffic and inform drivers. Intelligent roadways gather information through road speed sensors and digital cameras and pass it back to a main command center for processing. At the command center, managers assess conditions and utilize a variety of methods to optimize traffic flow. The command center can alert rivers to problems and re-route them using dynamic messaging signs, and traffic accidents are quickly detected and responses are dispatched..

SDI is the program manager for one of the largest intelligent roadway systems in the world. Spanning over 274 miles of interstate tollways in 12 counties, the system includes roadway speed sensors, digital cameras, and dynamic digital signage.
