Technology at WestConnex

Smart Motorways

The M4 Smart Motorway Project uses technology to monitor traffic conditions, fix congestion hotspots and respond to incidents on the M4.

The technology includes systems to manage the rate in which vehicles enter the motorway at certain points and variable speed limiting based on real time traffic monitoring.

WestConnex M4 has technology embedded along the roadside to ensure motorists are getting the smoothest and safest journey possible. The WestConnex team at the Motorway Control Centre monitors the WestConnex M4 24 hours a day, seven days a week. Smart Motorways make journeys safer and smoother by:

Using Variable Speed Signs to control the speed and direction of traffic 

Emergency breakdown bays are located every 1.5km throughout the tunnel 

Installation of Automatic Vehicle Incident Detection system (AVID) cameras throughout the tunnel can detect if a vehicle is broken down and notifies the MCC staff instantly, allowing WestConnex to deploy incident response crews within minutes 

Constantly monitoring traffic, cameras relay a live traffic feed back to the traffic monitoring team, allowing operators to respond to any condition changes in real time

Variable Message Signs display real time travel information for motorists 

Access Bluetooth navigation technology underground in the New M4 Tunnels

GPS dropouts on popular smartphone navigation apps are a thing of the past for motorists travelling in the WestConnex New M4 Tunnels.

In a NSW first, Waze Beacons navigation technology is now available in the WestConnex New M4 Tunnels giving motorists access to reliable GPS navigation when travelling underground. 

WestConnex partnered with Waze to install more than 500 navigation Beacons throughout the New M4 Tunnels to ensure location services and navigation apps can keep tracking underground.

The technology produces a Bluetooth signal that helps guide a navigation system on a phone or tablet when a GPS signal hits a blackspot or coverage isn’t available.

The in-tunnel navigation beacon technology will be progressively rolled out across the WestConnex motorway network.

The Waze navigation app can be downloaded for free and is available to anyone with an Android or Apple device.
