Austroads has published a research report which analyses the impacts of an aging heavy vehicle fleet and explores measures that have been used to manage the challenge in Australia, New Zealand and internationally.
Trucks in Australia and New Zealand are older than in many other countries. This is due to low barriers to entry, exacerbated by having no secondary disposal market, and few restrictions on how and where they operate.
Richard Delplace, Austroads transport network operations program manager, says the oldest heavy vehicles impact the community in several ways, including air pollution, noise, and health but, until now, this issue has been hard to define and manage.
“Defining aged heavy vehichles by their emissions standard provides the clearest definition and will likely result in the greatest positive impact of any targeted actions,” Delplace says.
“Our study presents examples of actions that could directly influence the aged truck fleet. These can be broadly classified into four types of action: road access restrictions, financial penalties, financial incentives, and retrofit/repower programs.
“Freight and heavy vehicle regulation and planning are currently being reviewed on several fronts. This is the perfect time to consider this issue to ensure it is included in future planning for a safer, healthier and cheaper freight network,” he says.
In this project, an aged heavy vehicle was defined as being above 4.5 tonnes GVM, used in freight transport and manufactured before 2008. Three sub-classes of categorisation are based on the vehicle’s compliance with exhaust emission standards in the Australian Design Rules.
Mark Gjerek, lead consultant on this research, says the nature and structure of the national fleet and freight sector means that the aged truck problem is difficult to overcome with equitable and effective measures.
“Across the world, governments have taken action to reduce the impacts of aged trucks in their jurisdictions. International best practice suggests that different kinds of measures should be combined to achieve the greatest effect,” Gjerek says.
Webinar
A free webinar on the study will take place Thursday, May 27, from 1:00–2:00pm AEST.
The research team of Mark Gjerek, Nathan Gore-Brown and Alun Morgan will present the main findings including:
- why older trucks are used
- the facts about environmental, health and safety costs of using aged trucks
- best-practice examples for managing community impacts
- other insights and implications from the research.
