WELCOME TO PERFECT CITY

Environmental psychology is a field of science that looks at the ways in which we are affected by our surroundings. Almost every aspect of the built environment, from the colour of hospital walls to the type of grass used in parks, can have a dramatic impact on crime, health, education, commerce and happiness. The BBC Focus magazine reports on how psychologists are teaming up with designers to build spaces that are healthier and safer.

Classic trick

In the mid-nineties in Montreal, it was discovered that playing classical music through the public address system would drive away crowds of annoying teenagers and cut crime. The idea soon caught on. Now, classical music is played in over sixty underground stations in London.

Stop signs

Sometimes less is more. Towns such as Bohmte in Germany have found out that the best way to slow traffic is to remove all road signs and markings. Without these guides, drivers have to slow down and negotiate rights of way with other drivers, cyclists and pedestrians. The records show that there have been less accidents and injuries since the removal of the signs in Bohmte.

Getting rid of distractions

Researchers in Manchester found that pickpockets took advantage of pedestrians distracted by confusing environments. By removing visual clutter and making spaces easier to navigate, pedestrians are more aware of their surroundings and less likely to become victims of crime.

Delay stress

Travelling long distances in a city isn’t necessarily stressful, but delays are. A study of rail travellers found the highest level of stress hormone cortisol among those who perceived their journey as unpredictable. Real-time transport updates, such as a text message sent to your phone letting you know exactly when the next bus will arrive, have been found to reduce stress.
