Effectiveness of arterial road congestion initiatives

We plan to assess the effectiveness of arterial road initiatives in managing traffic patterns emerging after the COVID-19 pandemic.

Why this is important

Research on travel preferences after the COVID-19 pandemic lockdowns shows a likely shift away from public transport towards more commuting by car. The research shows that working from home is also unlikely to offset this change, resulting in a net increase in car use.

News reports from 2022 showed that Melbourne’s traffic had nearly returned to pre-pandemic levels. In some congestion ‘hot spots’ traffic has exceeded pre-pandemic levels.

Road congestion negatively affects the efficiency and reliability of the transport system. In 2018 Melbourne’s traffic speeds were ranked among the lowest of Australia’s capital cities. 

In 2015, the avoidable cost of congestion in Melbourne was estimated at $4.6 billion and was projected to increase to $10.0 billion by 2030.

In the last 3 years the Victorian Government has invested over $450 million in projects aimed at reducing congestion on arterial roads. 

These investments include: 

• new cameras and electronic signs
• more incident response teams 
• expanded peak-hour tow-away zones in key locations.

What we plan to examine

This is a reasonable assurance performance audit.

We will assess how effective recent arterial road investments (with a particular focus on the application of road technology) have been at improving traffic flow and reducing congestion on arterial roads.

It will include a case study on a recent arterial route investment, such as the Streamlining Hoddle Street project, to assess the benefits.

Who we plan to examine

DTP, including functions that VicRoads previously carried out
