Australia does need infrastructure to spur growth and support jobs - that idea comes with a big “but”.
Analysis of the business cases for three of the biggest projects deemed “high priority” by Infrastructure Australia raises questions about the process.
By expanding our understanding of streets and enhancing their design, every street corner could become a space to socialise, to exercise, to play, or to trade.
One potential benefit of WestConnex, which remains untouched, is that it could relieve Sydney’s city centre from cars and make it more pedestrian-friendly.
A rethink in the approach to road freight transport safety is urgently required to reduce fatalities and injuries.
Adding a bit of fungus to the initial ingredient list might be one way to endow concrete with the ability to fill in any bits of damage that occur, without the need for human intervention.
If the strategies we put in place to make cycling safer were taken up in earnest the result would often be chaos.
With frigid temperatures and snow in the forecast, slippery roads can’t be far behind. Salt keeps roads safe, but it’s harmful to aquatic environments.
Chinese investment is driving an unprecedented investment boom in global infrastructure. But despite its claims to be pursuing green development, China’s building bonanza is harming the planet.
A city-wide experiment suggests well-designed road use charges could ease congestion by encouraging people to drive at different times, take other routes or use other transport.
Conventional approaches to assessing the impact of cameras on collisions may be overoptimistic.
Instead of focusing on freeways, governments should change the way we pay for urban roads and public transport.
Australians are crying out for political leadership. One way our leaders can redeem themselves is by getting to work on a complete shake-up of how we pay for and use transport infrastructure.
The implications, economic and otherwise, of this massive policy change are only beginning to sink in.
The American Society of Civil Engineers gives US infrastructure a D+. What is it that we’re doing wrong?
How might we, and our nation’s roads and highways, need to change as autonomous vehicles become more ubiquitous? We know a lot of the answers, but not all of them.
Melbourne’s proposed road project relies on assumptions that inflate estimates of the traffic the new link will carry – but other choices about the future of transport are open to us.
The U.S. owes much of its prosperity to investment in public goods like highways, parks and schools. Trump’s budget poses a threat to these goods, which have already been on the decline.
Bike lanes in South Africa were meant to encourage commuter cycling and ease congestion but in Johannesburg the initiative garnered more outrage than support.
