Incident Response Service

The Incident Response Service (IRS) deploys specially trained, mobile road crews on Perth’s freeways and CBD roads to assist with the quick and safe removal of broken down vehicles, debris and other obstructions, helping to restore normal traffic conditions as quickly as possible.

The IRS is an ‘on road’ monitoring service, but does not offer general breakdown assistance like roadside services or towing companies.

As demand increased on Perth's freeways and highways, from February 2018 we trialled an expansion of hours and geographical coverage helping road users have a safer and more reliable trip.


Current Status

Since its inception, the service has helped minimise incident related congestion by clearing a safe path around situations that can adversely affect the steady flow of traffic. Each month the IRS attends on average 60 breakdowns, 70 incidents and collects over 400 items of debris.

The IRS has been well received by the public who have taken the time to provide Main Roads with some feedback regarding their experiences:

"It was (also) of immense assurance to know that the Traffic Operations Centre was aware of my situation and responded so efficiently, courteously and professionally to my circumstance"

"(The IRS provided) a fantastic service, much needed and much appreciated".

On average, it takes the IRS 3.4 minutes to respond to a call out in the tunnel, enabling road users to continue on their journey with minimal disruption whilst providing much needed "on the ground" information to supporting groups to help manage and mitigate an emerging issue effectively.

When will the expanded service operate?

A weekend trial is underway of the IRS in addition to the current service and will operate:

  • Saturday to Sunday from 7am to 6pm
  • Use the latest generation incident response vehicle
  • Operate on Perth's main freeways, highways and CBD roads
  • Additional mid-week patrols


Relocating vehicles - how does it work?

A video demonstration of the IRS is available on our YouTube channel .

The IRS vehicles are specially designed with a "push pad" at the front, made of soft foam that shapes to the design of your vehicle to move it to a safer location. Vehicles assisted by the IRS that are still mobile (such as those that have broken down) will be relocated to a nearby safe location free of charge.

The IRS is supported by additional CCTV cameras installed within the CBD to provide the Traffic Operations Centre with improved visibility of road conditions. This means IRS vehicles can be dispatched quickly and safely to where they are needed.

How do we know if there is an incident?

Central to the IRS is the Main Roads Traffic Operations Centre (TOC) – a team of experienced operators who monitor and manage the road network 24 hours a day, seven days a week.

The TOC use various tools to identify an incident including traffic monitoring cameras, detection and alarm systems, and information provided by emergency services, the media and the public. The IRS vehicles also provide the TOC with on-the-spot traffic reports and updates as they travel the network and respond to incidents.


How the IRS can benefit you

The IRS aims to minimise congestion caused by incidents and keep Perth road users moving safely and efficiently as possible.

The benefits of the service include:

  • Helping to maintain traffic flow and minimise congestion caused by incidents through the Northbridge Tunnel, the CBD and on Perth’s freeways and major arterial routes.
  • Incidents are attended to efficiently, reducing the likelihood of any follow-on incidents occurring.
  • The reliability of your travel times is improved, meaning smoother journeys in the Perth metropolitan region.
  • The IRS can assist emergency services to perform their role effectively and safely.
  • Provides a safer work environment for emergency services, tow operators and road side assistance providers.
  • IRS crews have the ability to provide on-the-spot traffic reports and updates directly to the Main Roads Traffic Operations Centre, giving them real-time information as they attend to incidents.
