Research into people's reactions to emergencies aims to make sure there are more survivors in future.

Imagine you're stuck in a burning building, trying desperately to escape. After stumblingto the end of a smoke-filled corridor, you have to choose whether to turn left or right. The decision could determine whether you live or die – but the way you make it is not asrandom as you might think, according to Ed Galea, professor of mathematical modelling at the University of Greenwich.

Galea has forged a career out of working out the science and psychology behind how people's brains function in disaster zones. He has interviewed thousands of survivors, from 300 people who escaped the World Trade Center on 9/11 to plane crash and Paddington rail disaster survivors. The results of his research are used by governments, building designers and emergency workers around the world to try to plan for the effects of future catastrophes.

His latest project, funded by a €2 million (£1.8m) European Union grant, is BeSeCu (Behaviour, Security and Culture), which involves trying to understand whether culture affects the way people behave in emergency situations. "The question we're answering is, do people from different countries behave differently in a crisis?", says Galea. "Most of the data that's used in evacuation analysis is from the UK, US and Australia. There's animplicit assumption that people everywhere behave the same, but we're not sure that's true."

So BeSeCu is carrying out "unannounced evacuation drills" in multistorey university library buildings around Europe, including Poland, Czech Republic and Turkey, and comparing the results with evacuation data from Brazil and the UK. "We're going to compare the data on response time and behaviour. If it varies in different places, that will suggest a need to change how we plan for emergency situations – we'll have to take a much more localised approach."

Galea's interest was triggered by victims' responses to a tragic fire in the Daegu underground in Korea. "I looked at photographs of the inside of burning carriages, and collaborated with a Korean researcher who interviewed survivors. Most sat around, waiting for instructions from an authority figure. When I presented the findings at a UK conference, it was suggested that my data was irrelevant because 'that would never happen in the UK'. So I started wondering whether people around the world react differently."

Working at Greenwich's Fire Safety Engineering Group, Galea and his team have designed Exodus, a computer modelling system that can simulate how people behave in emergency evacuations, which is used in 33 countries. It was used in the design of London's O2arena, Sydney's Olympic stadium, the "bird's nest" arena in Beijing and the Airbus A380.

Now he is adding to the model by analysing data from interviews with survivors of the 7/7 terrorist attacks in London and the Madrid bombings. "By studying how people responded on the underground trains and in the stations, we hope to better understand how the perception of risk, reaction to authority figures and interaction with other survivors influences emergency behaviour." The findings will be used to improve computer software so it better reflects how people behave in emergencies and can be more reliable in building design.

There are also practical ideas that are easier to implement, Galea says. "I'm looking at how people respond to alarms and instructions. If people on trains always wait for an official to tell them what to do, then perhaps we need to improve communication systems on trains so they have a better chance of working in extreme situations."

Galea is also investigating how people think when trying to escape house fires or a flooding house. "We've set up an online survey looking at how people move – at intersections, do they go left or right, for example. So far it seems that left-handed and right-handed people behave differently, and so do people who drive on different sides of the road. Working out the patterns will give people a better chance of surviving future disasters."

Galea, who spends his days mapping human behaviour, fell into his work "completely by accident". More than two decades later, he has amassed plenty of advice on getting out of a fire or crash alive. "The main thing is having good situational awareness," he says. "Understand the environment you're in, whether it's a plane, train, ship or building, know where your nearest exit is and how you'd escape in a hurry. If you're travelling with family, plan what you would do in an emergency, like whether you'd try to reunite before escaping, or meet outside."

On planes, Galea recommends choosing a seat close to an exit. "I always try and sit within five rows of an exit on an aisle seat," he says. "Once you're seated, count the rows to your nearest two exits in case it becomes too dark to see." Galea stresses, however, that planes are "really quite safe".

One thing that does make him upset, however, is disaster movies. The latest to hit our screens is 2012, which Galea says makes him "frustrated about how badly Hollywood gets it wrong".

"Disaster films convey completely the wrong view of how most people behave in these kind of situations," he says. "Hollywood shows people panicking, but my research shows that 9.9 times out of 10, people don't turn into crazed individuals, but behave quite rationally. They tend to help each other, too."

That, says Galea, is a crucial part of his job. "The knowledge that most people react in a humanist way helps me to get in up in the morning – I come to work knowing that people tend to behave in a supportive, helpful way in emergencies, so any way we can help inform intelligent building design and disaster strategies will help them to survive."
