Samenvatting
The usefulness of providing feedback from technology to moderate teens' risky behaviors was studied by conducting a before and after experiment. 32teens vehicles were fitted with an in-vehicle technology designed to identify occurrence of unsafe driving events (e.g. sharp turning, excessive braking and accelerating, swift lane changing). The events frequency in over 18,000 trips was analyzed using mixed-effect regression models with Poisson errors and several graphical methods. Results indicate a reduction of more than 50% in events frequency when feedback was available. These results indicate that providing feedback from technology can reduce teen drivers' risky behavior.
