AB A usual traffic calming measure (TCM) to reduce vehicle speed in urban areas is the trafficlights that turn red when a vehicle exceeds the speed limit. These traffic lights can detect ifan approaching vehicle exceeds the speed limit and, if so, stop it by means of a red light. Itis generally employed in interurban roads rather than in big cities, where the presence oftraffic lights is common. In a rural road crossing a small village, they are deployed to reducethe risk of accidents to vulnerable road used when vehicles arriving at high speeds tend toconflict with pedestrians attempting to cross the road.The aim of this paper is to analyze the efficiency of this TCM, preceded by panels indicatingthe vehicles’ speed, by controlling the vehicles’ speed in the A-132 road that crosses throughthe village of Azazeta in the province of Álava/Araba (Spain). Different sequence of theTCMs can be found in each direction approaching the village; in A direction, warning trafficlights, the panel indicating the speed and the traffic light turning red; and in B direction, thepanel, the warning traffic lights and the traffic lights turning red.However, similar results were obtained in both directions for average speeds and percentile85 of the speed distribution at the traffic lights, and speed was reduced as motorists facedthe TCMs. However, although average speed was below speed limit (50 km/h), the percentile85 was over it, implying that more than 26% of drivers did not respect the red light.Moreover, after the traffic lights turning red, motorist speed up and higher values weremeasured at the midpoint of the urban segment, the place where pedestrians use to crossfrom one side of the village to the other one, although no pedestrian crosswalk is available.
