CAVI components

The CAVI project includes 4 components:

• Cooperative Intelligent Transport Systems (C-ITS) pilot
• Cooperative and Highly Automated Driving (CHAD) pilot
• Vulnerable road user pilot
• Change Management

Cooperative Intelligent Transport Systems (C-ITS) Pilot

The largest component of CAVI is the Cooperative Intelligent Transport Systems (C-ITS) Pilot. The pilot will take place on public roads in and around the City of Ipswich.

The pilot will be delivered in 2 phases – planning and pilot deployment –a decision made between each phase will confirm the investment logic and the pilot approach.

Testing will start with the C-ITS safety use-case, including vehicle-to-infrastructure (V2I) and vehicle-to-vehicle (V2V) applications. There will be around 500 public and fleet vehicles retro fitted with C-ITS technologies, and roadside C-ITS devices installed on arterial and motorways. These devices allow vehicles and infrastructure to talk to each other to share real-time information about the road and to generate safety-related warnings messages for drivers.

Use-case applications

Emergency braking warning (V2V)

This warning alerts drivers to a cooperative vehicle braking hard some distance ahead.

In-vehicle speed warning (V2I)

This warning provides drivers with information about active, static or variable speed limits. It then alerts them if they are exceeding that limit.

Turning warning for bicycle riders and pedestrians (V2V)

This warning alerts drivers to pedestrians or bicycles crossing at an upcoming intersection.

Road works warning (V2I)

This warning alerts drivers to upcoming roadworks, giving them time to slow down or change lanes.

Back-of-queue-warning (V2I)

This warning provides drivers with information about an upcoming traffic queue.

Red light violator warning (V2I/V2V)

This warning alerts drivers that another cooperative vehicle is likely to run a red light across their path at the intersection ahead.

Red light warning (V2I)

This warning alerts drivers if it’s likely that they’ll drive through a red light ahead, unless they brake.

Stopped or slow vehicle warnings (V2V)

This warning alerts drivers of an impending rear-end collision with another cooperative vehicle ahead of them.

Hazard warning (V2I)

This warning alerts drivers to upcoming hazards, such as water on the road, road closures, or a crash.

Cooperative and Highly Automated Driving (CHAD) pilot

A small number of cooperative and automated vehicles will be tested on public and private roads using trained and public participants. The pilot will assess:

• asset readiness (that is, can existing signs and lines be read by automated vehicles)
• driver behaviour (human machine interface)
• vehicle performance

Vulnerable road user pilot

This pilot will seek to develop and undertake proof-of-concept tests for new technology applications that address specific vulnerable road user priorities including bicycle, pedestrian and motorcycle safety issues.

Change Management

A change management process for the Department of Transport and Main Roads to consider the capabilities and resources required to support widespread deployment of these vehicles on our roads.
