Two experiments were conducted to examine alternatives to enforcement as a means of reducing speeding behavior. The first employed transverse lines painted on the roadway at progressively diminishing distances apart to produce an alerting response and an illusion of vehicle acceleration. Data were collected on 247,036 vehicles during a period of several weeks. The number of drivers that were exceeding the recommended speed by more than 30 km/hr was reduced by 25 percent, but this effect on speed began to disappear after 3 weeks. The second experiment provided drivers with feedback (using a traffic sign) about the percentage of drivers who were not speeding on the previous day. Data gathered on approximately 690,000 vehicles during 3.5 months indicated that excessive speeding could be reduced by 40 percent. This speed reduction was maintained for weeks after the sign was removed. The implications of these findings for alerting drivers and reducing speeding behavior are discussed.
