Drive time signs for Perth


Perth drivers can now see real-time estimates of journey times on overhead electronic signs on the main arterial routes north and south of the city

Drive time signs for Perth
The instillation of drive time signs should come as good news to drivers in Perth

 

The live travel time estimates on the Mitchell and Kwinana Freeways 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, and the instillation should come as good news to the estimated 300,000 drivers who use the route every day.

Western Australia’s Transport Minister Rita Saffioti says it’s a huge leap forward in road infrastructure that will be welcomed by drivers.

 "In a first for Perth, we are using smart technology to communicate freeway travel times to motorists in real-time," she says.

"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.

"Moving forward, we will continue to look at ways to introduce technology to improve congestion and journey times."

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

The initiative aims to tackle the problem of drivers having no visibility of how traffic is flowing or whether they should seek an alternative route. This leads to driver frustration because of the uncertainty of how long their journey will take.

The signs will be active between 6am to 10am and 3pm to 7pm on weekdays.

The Kwinana and Mitchell Freeways will also be widened, with construction due to start next year and an announcement on the construction due later this month.
