World Hacks visits a long, narrow street in the heart of the Dutch city of Eindhoven. A quarter of a mile long and lined with pubs and bars, Stratumseind is a drinking destination for the country’s young people and football fans. Unfortunately, the good times are frequently marred with violence. On any given Saturday night, police make about 20 arrests or detentions, many involving alcohol-related aggression.

Now the city authorities are using sophisticated technology to monitor the activities of the street, including cameras that can count people and microphones that can tell the difference between someone squealing with laughter and screaming in fright.

Stratumseind’s drinkers are also unwitting participants in a series of experiments to monitor whether subtle changes in their environment have an impact on their behaviour – whether that’s changing the colour of the street lights to calm people down or introducing a scent to help de-escalate tensions.
