910.2 How ITS Works

ITS is comprised of many components that, when combined, effectively fight traffic congestion.

• Fiber-optic cables communicate information between monitoring devices and the MoDOT Traffic Operations Center.
• Sensors provide information on average traffic speed and volume.
• Closed-circuit cameras at major interchanges, intersections and river bridge crossings provide live video information on traffic flow.
• Permanent mounted variable message signs inform motorists of incidents ahead and supply alternate route options.
• Highway Advisory Radio signs equipped with lights that flash when there is new traffic information.

• Integration of regional/urban traffic signal systems.
• The toll-free cellular call-in system routed to the MoDOT Traffic Operations Center or the Missouri Highway Patrol for immediate response to incidents.
• Improved highway mile markers identify exactly where a motorist is to accurately pinpoint the location of incidents.
• In Kansas City and St. Louis, Emergency Response helps stranded motorists to get their vehicles out of traffic lanes and, if possible, running again.
• Advanced Traveler Information on weather conditions, incidents and traffic congestion levels.
• Direct media tie-in to traffic information for broadcast to motoring public.
• Direct emergency services tie-in for immediate response to incidents.
• Sharing information with transit centers regarding traffic flow.
• In urban areas, ramp-metering smoothes traffic flow on the highway near entrance ramps.
