Maniacs get behind the wheel

By Duncan Graham-Rowe DRIVING simulators can help people to learn the mechanics of driving, but they can’t teach them to cope with the behaviour of other motorists. Now a computer scientist at the University of Leeds has worked out how to make cars in a simulator behave as if they were driven by real people—some of whom are aggressive and drink too much. Each “drone” vehicle in the Leeds simulator has its own distinct personality modelled on research into driver behaviour in real life. Depending on their personality, age and sex, the drones show varying levels of aggression, fatigue or alcohol consumption. The effects of these on their driving are expressed through their speed, stopping distances and reaction times. Steven Wright, who developed the system, says existing simulators are highly predictable and unconvincing. “For a simulation to be effective we need the environment to be realistic, otherwise the driver won’t respond as they would to a real vehicle,” he says. His model uses an algorithm based on fuzzy logic to vary the mix of drivers on the road at a particular time. Wright says it is quite possible for the drones to crash into one another,
