Traffic in Accra, Ghana. With more people moving into cities, careful town planning is critical for sustainable development.
Urban planning and development in Africa has been fraught with many challenges. A study of Accra and Nairobi provides some lessons on what needs to improve.
World Car-Free day has at its heart a noble aim - but the evidence suggests that a one off event can't really make a world of difference.
The evidence is in: cars are a risk to public health, and we need to find alternatives.
Coming soon to a runway near you. Or not.

Innovative ideas about how to decarbonise shipping are helping to harness the original renewable power source once more.
There are cutting edge technologies on the cards, but can anything displace railways?
The resurgence of cities is set to help us make our dependence on gas-guzzling personal transport a thing of the past.
While there may be bad congestion in parts of Australia’s cities now, data suggest that car use has peaked.
There is a new fear on the block ... traffic congestion. But do we have to accept that congestion trends will overwhelm us? Is it really right to fear congestion?
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.
The real world is finally catching up with 1950s sci-fi.
Cars are dirty and wasteful. Large fleets of autonomous taxis could cut emissions and reduce inefficiency.
National priorities can help focus our research efforts.

Gladys Berejiklian's first budget as NSW Treasurer includes some infrastructure goodies but misses an opportunity to reduce the state's reliance on property taxes.
A shining example. No, really.

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.
Time to wave them off.
In some significant ways, Americans have fewer avenues for advancement than the characters of Mad Men do.
More mines, more roads, as the government puts its drive towards economic development ahead of all else.

Amid talk of paths to surplus and investing in infrastructure, both sides of politics seem to have forgotten Australia's longstanding responsibility to govern sustainably, and not just for the economy.
People travelled a total of 40 trillion km in 2012, mostly by car.
Across the western world, the distance people travel is starting to fall. That's a good thing, for us and the environment.
