The Colorado Department of Transportation (CDOT) has started testing the Smart Signs system on US 36, which is one of the two corridors in the state, to improve traffic flow and safety.

The overhead signs have been installed between Federal Boulevard in Westminster to Table Mesa Drive in Boulder, which would help drivers to be better prepared for problems such as traffic congestion and lane closures caused by accidents, disabled vehicles and other obstacles.

During the field tests, motorists will be provided with real-time incident information when the signs are activated, and the driver behaviours of the travelling public will be observed by CDOT.

"This is the first time a system like this has been installed in the state and we anticipate it’ll improve safety."

CDOT transportation systems management and operations director Ryan Rice said: “For years, CDOT has studied similar traffic management systems in other states.

"We took the best practises of those states and are applying those to our highways.

“This is the first time a system like this has been installed in the state and we anticipate it’ll improve safety on the corridor by allowing drivers to be better prepared for problems ahead.”

CDOT will also ensure that the Smart Signs systems are working properly, and check if they are displaying the right information to commuters on the highway.

As part of the North I-25 Express Lanes, the system will also be deployed on southbound Interstate 25 from 120th Avenue to US 36.

The Smart Signs system seamlessly uses information supplied by cameras and vehicle detectors to gather and process the information about current traffic conditions, and displays the information on overhead digital signs.

The system is expected to enter full-time activation on US 36 in the next several months.
