Perth’s 300,000 daily freeway commuters now have access to real-time estimates of journey times on overhead electronic signs.

The live travel time estimates aim to inform motorists of traffic conditions ahead and reduce driver frustration.

The time estimates are calculated using existing in-road vehicle detection sensors and a new smart technology system.

Every few minutes, the system uses an algorithm that considers distances and current average travel speeds to estimate travel times, which are then published on the overhead electronic freeway signs in real time.

Minister for Transport Rita Saffioti, said, “In a first for Perth, the State Government is using smart technology to communicate freeway travel times to motorists in real-time.

“Displaying travel times will reduce driver frustration by providing motorists with a quick understanding of the current road conditions ahead and giving them an estimated time of arrival to key freeway exits.

“They are also able to make more informed en route travel choices by being able to change their journey based on the displayed travel times that can be used as a guide.

“This is a great example of a low-cost, high-impact solution to improve traffic flow and get the most out of our existing infrastructure.”

Travel times will automatically be displayed on nine selected freeway signs during both morning and afternoon peak periods on weekdays.
