All systems go for State's first smart motorway


23 November 2020

Drivers in Sydney are today using the State’s first smart motorway on the M4, after it was switched on for a month long trial.

Minister for Transport and Roads Andrew Constance said the $600 million M4 Smart Motorway project will provide safer and more reliable trips.

“Crews have been working hard since December 2017 to build the infrastructure needed for this amazing system, which will improve travel times for more than 150,000 vehicles using the M4 each day,” Mr Constance said.

“This morning we saw the overhead gantries activated between Penrith and Parramatta, with the rest of the new technology being switched on over the next month to allow drivers to get used to the changes.

“Journeys along the M4 will now look different so we really need drivers to be aware of the changed traffic conditions and are encouraging drivers to take extra care.”

Transport for NSW Chief Operations Officer Howard Collins said the new ramp signals and overhead gantries will improve traffic flow.

“This technology will ensure less stop-start traffic and sudden braking at some of the most congested points along the motorway,” Mr Collins said.

“Once all systems are switched on, they will talk to each other and automatically adjust to incidents without a manual operator intervening which is the way of the future.

“When the entire M4 Smart Motorway is operational, journey times along the M4 between Penrith and Parramatta are expected to be reduced by up to 15 minutes in the morning peak.”

The trial will run through to Sunday 13 December, with the M4 Smart Motorway on schedule to be fully activated later this year.
