RADAR AS A SPEED DETERRENT: AN EVALUATION

THIS STUDY EXAMINES SPEEDS OF VEHICLES COLLECTED OVER AN ELEVEN-DAY PERIOD IN 43 NORTH CAROLINA MUNICIPALITIES UNDER VARYING EXPERIMENTAL CONDITIONS (E.G., MEDIA PUBLICITY IN ONE GROUP OF CITIES VS NO PUBLICITY IN A COMPARABLE GROUP GIVEN BASELINE OR "BEFORE" SPEEDS FOR BOTH GROUPS). THE EVALUATION PROVIDES CONVINCING EVIDENCE THAT, IN THE 35 MPH PROPORTION OF SPEEDERS (FROM 0.669 TO 0.464) AND THE AVERAGE SPEED OF TRAFFIC (FROM 38.7 MPH TO 35.5 MPH) CAN BE ACCOMPLISHED BY A COMBINATION OF EFFORTS (I.E., VISIBILITY OF PATROL VEHICLE, TICKETING, AND MEDIA PUBLICITY). HOWEVER, EACH OF THE FACTORS CONSIDERED ALONE REFLECTS ONLY MARGINAL EVIDENCE OF EFFECTIVENESS.
