When cars, trucks, bikes and pedestrians come together at an intersection, design makes the difference between collisions and safety.
Collisions at intersections between motor vehicles, cyclists and pedestrians cause many deaths and injuries. Design that considers how each group approaches intersections improves everyone's safety.
The settings on traffic lights make pedestrians wait longer by giving higher priority to vehicle traffic.

Everyone doesn't simply wait their turn at traffic lights. Signals are set up to enable a 'green wave' for cars and adjust to heavy traffic, making walkers wait longer no matter how many there are.
Decisions made by engineers today will determine how all cars drive.
The biggest ethical challenges for self-driving cars arise in mundane situations, not when crashes are unavoidable.
Is it going to stop?
In the wake of a self-driving Uber car killing a pedestrian in Arizona, an ethicist examines the state of autonomous vehicle development.
People stroll along Moshoeshoe Street in Emfuleni.
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.
It's time to turn Oxford Street into a haven for walkers.
The clock change's impact on commuter numbers highlights the need to use street lighting more effectively.
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.
Beijing residents with a variety of approaches to urban air pollution.
In recent years the number of motor vehicles – and the pollution they generate – has grown astronomically, leading some citydwellers to wear facemasks in the hopes of protecting themselves. So do they work?
Sales of electric vehicles are growing fast, especially in Europe.
Shifting to plug-in cars wouldn't be enough to max out global oil consumption by 2040. But it could help make that happen if cities pitch in and ride-sharing doesn't crowd out public transportation.
What can we do to avoid clashes between users of shared paths?
The golden rule of shared paths is that the person in the less vulnerable position should be mindful of the more vulnerable user.
Not enough time to cross.
If we want older people to stay mobile, we need to look at the everday issues they encounter first.
Most road-safety initiatives prioritise a rapid clearing of the road so cars can pass.
In contrast to increases in vehicle safety over the decades, we have seen little new technology to ensure the safety of pedestrians – and current innovations are still based on a car-centric approach.
Racewalkers turn a corner – keeping one foot on the ground – during the women’s 20-km event at the 2012 London Olympics.
Racewalking has been part of the Olympic Games since 1904, but gets little respect in the United States. That might change if Americans knew a little more about it.
Many mobile phone users now text, or intently perform some other function on their phone, while walking.
Banning pedestrians from using their phones seems a natural extension of the prohibition against mobile phone use while driving.
Everyone has experienced it. Striding along in a purposeful hurry, your progress is thwarted by a slow-moving pedestrian, dawdling along the pavement. Perhaps they’re talking into their mobile phone, looking…
The way we get around has been revolutionised over the past half a century. But old habits die hard.
