A new study forecasts that thousands of miles of new road construction will cut through tiger habitat across Asia by 2050. Planning can make these projects more tiger-friendly.
How to get from A to B – in the future.

Most people do not know the right-of-way rules, but a starting point should be that pedestrian needs and safety take priority. Current road rules are biased towards driver convenience
Peak-time drivers to the CBDs of Sydney and Melbourne typically earn much more than the average worker.
Commuters who drive to and from the CBD typically earn much more than most. Concerns about the fairness of charging drivers who use these busy roads at peak times are overblown.
Turning from the conflict of airport expansions to a vision of a low-carbon transport system.
The eight-mile ‘river of flowers’ that grows alongside a motorway near Rotherham, UK.
Britain's councils are cutting roadside verges less often to allow vibrant wildflower meadows to bloom.
Taxis have traditionally competed for kerbside space in our cities, but they now have many new competitors.
Cities must manage all the competing uses for limited roadside space to avoid congestion and maximise efficiency. And that begins with reliable data.
The real ethical challenge of driverless cars is not deciding how they respond in emergencies – it's facing up to the failings of human drivers.
Having fun yet?
Despite efforts to encourage a shift to sustainable transportation, traffic congestion is often the focus of debates over mobility. Motorists endlessly demand more roads, but is this really a solution?
The problem of unsafe drinking water afflicts poor communities most.
Just as America's highways, sewage systems and water pipes need fixing, so does the growing gap between rich and poor. Trump and the Democrats could use that money to address both.
Fixing cracks and potholes in concrete roads like this one may be easier with help from bacteria.
Patching concrete sidewalks, roads and bridges after every season of snow and ice is expensive. A team of engineers is now testing a new approach harnessing bacteria to patch the potholes and cracks.
The Morrison government’s infrastructure budget favours Victoria, in a change from recent budgets.
Despite boasts of 'record' infrastructure spending, relative to GDP it's comparable to previous budgets. What's different is that Treasurer Frydenberg has chanced his arm more over the longer term.
The Morrison government’s packaging of a bundle of roads spending as “urban congestion” measures is an acknowledgement that transport planning has been inadequate.
The focus on roads reflects the fact that this infrastructure program lags well behind the growth of our biggest cities, resulting in less-than-ideal transport patterns.
Commuters at Epping train station board replacement buses during work on the line for the Sydney Metro, the biggest of all the promised projects.
The major parties are promising projects costing tens of billions of dollars, with a surprisingly large overlap between them. Yet only two have been endorsed by infrastructure authorities.
Cycling advocates set up ‘ghost bikes,’ like this one in Brooklyn, in memory of bikers killed in traffic.
US cities were designed and engineered around cars. Now some are working to increase walking and biking, but the shift isn't easy.
Spraying salt onto roads is a safety measure.
When it snows, it pours – but why do municipalities treat the roads with salt? A chemist explains how salt affects water and ice.
Transport promises stretching as far as the eye can see: Victorian Labor’s big one is a $A50 billion suburban rail loop.
Whichever party wins, Victoria's new government will have promised the biggest transport infrastructure project in Australian history. So what are the promises and are they backed by proper assessment?
Rift Valley Road in Ethiopia.
Smart roads in Africa could help reduce the impact of flooding and other disasters that affect rural communities.
When a stream enters a culvert, the flow can be concentrated so much that water flows incredibly fast. So fast, in fact, that small and juvenile fish are unable to swim against the flow and are prevented from reaching where they need to go to eat, reproduce or find safety.
Our new invention tackles one of the greatest impediments to fish migration in Australia: culverts, those tunnels or drains often found under roads.
