Traffic crashes kill and injure millions worldwide every year and are a major drain on economic development. Improving road safety would produce huge payoffs, especially in lower-income countries.
On-street parking is an increasingly scarce resource as we take to our cars post-lockdowns. Here’s how to make the most of it.
We need to do more to curb tailgating, one of the most stressful and dangerous driving behaviours.
The UK has around 2,000 drive-throughs.
Drive-throughs not only increase air pollution and emissions, but also contribute to a car-centred culture that we need to avoid.
Self-driving cars could lead to increased traffic and pollution if they spur more travel by car.

Studies show that when people can ride in a car without having to operate it, they increase their car use. That could increase traffic and pollution, unless government puts a price on car travel.
China has given itself a major advantage over India by constructing a massive road network in the past two decades.

These results emphasise the high significance of the transport sector in Kigali’s air pollution levels and the need for further action to address air pollution from the sector.
The likelihood of commuting during both peak periods was slightly lower for telecommuters than for workers who commuted to work.
The potential benefits of telecommuting could quickly be erased because of the behavioural changes it brings about in the medium and long term.

The pandemic offered a tantalizing look at city life with fewer cars in the picture. But with traffic rebounding, there’s limited time to lock in policies that make streets more people-friendly.
The 21st century promised self-driving cars, but will they actually materialize?
The promise of self-driving cars hasn’t materialized, and we’re no closer to them becoming a reality.
