DRIVING 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.

The live travel time estimates

on the Mitchell and Kwinana

Freeways aim to inform motorists

of traffi c conditions ahead and

reduce driver frustration.

The time estimates are

calculated using existing in-road

vehicle detection sensors and a

new smart technology system.

The installation should be good

news to about 300,000 drivers

who use the route every day.

WA transport minister Rita

Saffi oti says it’s a huge leap

forward in road infrastructure

that will be welcomed by drivers.

“In a fi rst 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.”

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, between 6am

to 10am and 3pm to 7pm.

The initiative aims to tackle

the problem of drivers having no

visibility of how traffi c is fl owing

or whether they should seek an

alternative route. This leads to

driver frustration because of the

uncertainty of how long a journey

will take.

The Kwinana and Mitchell

Freeways will also be widened, with

construction due to start next year.
