Evaluation of a community-based intervention to enhance road safety.

A total of 300 motorists were recruited at public places to answer a self-report questionnaire on a new community-based intervention to enhance road safety. The intervention consisted of a speed-displaying device that was mounted next to the road and was visible to both motorists and the public. The device gives feedback about the current speed of the motorist. The majority of motorists believed these devices influenced compliance with the speed limit. They indicated they approached locations with these devices more slowly than similar locations without such devices. Moreover, they slowed down if they were going faster than the speed limit. They also said that their reaction to the devices was not influenced by whether they were driving in a community where they had friends or in a community where nobody knew them. These results were consistent across gender, age, levels of education, and professions.
