Sydney’s WestConnex road project has a surprisingly low ‘worst case’ cost estimate.
Our infrastructure systems should promise what is worth having, and then deliver what is promised.
The car-based logic of Melbourne’s 1969 transport plan has been deeply implanted into Victorians’ collective consciousness.
Most enlightened governments have realised the focus on private cars at the expense of active and public transport is not viable.
The time savings calculated in road project planning are based on incorrect assumptions about driver behaviour.
Projects like Sydney’s WestConnex and Melbourne’s Western Distributor don't account for real world evidence of driver behaviour in estimating travel time savings.
By persuading some drivers to travel a different route or at a different time, congestion charges can dramatically improve the flow of traffic.
Bigger cities increase wages, output and innovation, but also problems of congestion and pollution. Congestion charges can minimise these problems by dramatically improving traffic flows.
Major development banks are funding logging, mining and infrastructure projects that are having enormous impacts on nature. Here, forests are being razed along a newly constructed road in central Amazonia.
Big new investors such as the Asian Infrastructure Development Bank are key players in a worldwide infrastructure, and that could be bad news for the environment.
The politicisation of road funding decisions can make for wasteful spending.
Poor project selection is undermining economic growth in Australia.
In the battle for the road, bike riders come off second best.

New South Wales' new tougher bike laws reveal an ongoing war of the roads.
Would you take a longer route to work for the good of all?

Crews patch them, just to see these recurrent potholes come back again. New research focuses on microwaves zapping patches to make a more permanent pothole fix.

New data have revealed a disturbing trend in forest loss: the hearts of the world's forests are disappearing. To stop them bleeding out, we'll have to say 'no' to some developments.
According to all the data, urban car use has peaked, but official traffic modelling forecasts a remarkable reversal.
On average, people won't accept a commuting time of more than an hour. As cities grow ever bigger, new road projects can't achieve this, yet policymakers still rely on modelling that defies evidence.
Might the sun set on this technology before it’s even taken off?
Solar panels and roads — combining them just makes sense to help meet our clean energy needs, right? Maybe not quite.
The freeway presents a unique problem for the advance of autonomous vehicles.
Self-driving cars may not be the solution to all our transport woes. Better to focus on public transport.
Road development for logging in the Congo Basin.
More than thirty gigantic infrastructure projects threaten Africa's environment without offering economic benefits.
Plugging the gaps.
Allowing infrastructure to take over the job of keeping our vehicles running sends us further down a troublesome road.
Minneapolis learned the tragic consequences of crumbling infrastructure in 2007.
Our roads, bridges and schools are in dire need of aid, and the economic benefits of investment far outweigh the financial costs.
More research can improve how our existing transport infrastructure works.
A research focus on transport can help improve existing infrastructure and guide future developments, and tailor them to Australia's unique needs.
A well designed user pays system for Australian roads would help boost productivity.

The longer Australia waits for reform to road use pricing, the more commuters will ultimately end up paying.
If the choice is between waiting in their cars and long waits on inefficient public transport, many people prefer to drive.
Once a new road opens, people switch back to cars and congestion increases back to a steady-state point of gridlock. For lasting effectiveness, policy needs to include congestion charges and better rail services.
The mathematical modelling of traffic networks can throw up conflicting results.
The planning for any new road should include plenty of mathematical modelling. But getting the right numbers can be a challenge and there's the odd paradox to deal with as well.
