By identifying and applying the key rules governing the behaviour of each individual, agent-based modelling offers insights into complex phenomena like traffic jams and flocking.
New research has uncovered a previously unknown weakness in smart city systems: devices that trust each other. That could lead to some pretty terrible traffic, among other problems.
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.
The congestion charge has helped to ease traffic and raise funds. But the rise of Uber and other private hire vehicles have raised unforeseen challenges.
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.
Traffic congestion is the main cost that cars create when they use existing roads. Road use charges are a more efficient and fairer way to cover the cost and help ensure traffic flows.
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.

Millions of Americans rely on public transit to get to school, work or stores, but many can’t get the service they need. ‘Uberizing’ transit by offering more options on demand could fill the gaps.
New research shows that noise pollution in US cities is concentrated in poor and minority communities. Beyond regulating airplane noise, the US has done relatively little to curb noise pollution.
As the latest controversy about tunnel exhaust stacks and respiratory health plays out in the media, some community members are proposing solutions that just don’t make sense.
A recent study finds that noise from human activities is intruding into many parks and other protected areas. Creating quiet zones and noise corridors can help reduce impacts from noise pollution.
When planning major infrastructure investments, it’s important to know which road, freight and information networks are most important – and which proposals might make things worse, not better.
