Trial to improve intersection safety

An innovative trial has now been completed to improve safety at dangerous intersections, where almost one in four fatal crashes occur.

Advanced light detection and ranging (LiDAR) sensors were installed at a busy intersection in Yarraville for six months to detect the movement of road users including pedestrians, cyclists, cars and trucks to identify potential hazards.

The $2 million trial found new technology can accurately and reliably detect potential hazards within 0.2 seconds and has the potential to provide real-time warnings to alert road users of hazards.

The trial also investigated ways for intersection infrastructure to communicate hazard warnings to connected vehicles using roadside Co-operative Intelligent Transport System equipment.

This is the first extended trial using LiDAR technology to collect road data in Australia. The latest data shows 23% of deaths and 34% of serious injuries occur at intersections and the results of this trial will allow Road Safety Victoria to closely analyse the highly detailed information to help improve safety at intersections throughout Melbourne’s suburbs.  

The trial brought government and industry together to improve road safety and was delivered by Omni-Aware, a consortium of specialist technology companies including Intelligent Transport Services, Transoptim Consulting and IBIS Computers.

It is part of the Victorian Government's $9 million Connected and Automated Vehicle Trial Grants Program in partnership with the Transport Accident Commission, and supports Victoria's Road Safety Strategy 2021-2030, which sets ambitious targets to halve road deaths and significantly reduce serious injuries by 2030.

This is in addition to the 'don't block the box' trial which began last week with six busy intersections in Melbourne painted yellow to reduce the number of cars blocking intersections which can create congestion and puts other motorists in danger.
