Air pollution accounts for many deaths in Africa yearly. However, this may change if people learn to protect themselves and hold their leaders accountable.

City streets were built to accommodate cars, but the COVID-19 pandemic has scrambled our transport needs. Many cities are moving to make streets more people-friendly and less car-centric.
It can feel much faster to get the bus – but that could all be a matter of perspective.
Whether it’s birds in a flock or drivers in traffic, agent-based modelling can describe complex phenomena by applying a simple set of rules to each individual’s behaviour.

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.
The morning traffic builds up on the Tasman Highway at Montagu Bay. Congestion has become a hot issue for Hobart residents.

Hobart is a smaller city with big city problems that have become an election issue. Recent growth is creating traffic congestion that affects productivity, residents’ health and liveability.
New York soon may charge a fee to drive into central Manhattan as a way of reducing traffic and raising funds for public transit. An urban scholar says this step is overdue in the United States.
Reforming how drivers pay for the costs of their road use can help keep traffic flowing, which is just one of the potential benefits.

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 trial of 1,400 drivers across Melbourne suggests time-of-use charges can be effective in easing traffic congestion.

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.
When will cars be able to talk to their surroundings?

If all the elements in the transportation system are going to talk to each other, the people at the companies and government agencies that make those items need to talk to each other too.
Traffic congestion is concentrated along particular routes, such as the Eastern Freeway/Hoddle Street corridor in Melbourne.

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.
No wonder you’re always late. Drivers use a route that minimizes travel time on only a third of their trips. Here’s how real-world data can help planners fight traffic congestion.
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.
