Pérez Acebo, Heriberto Ziolkowski, Robert Gonzalo Orden, Hernán Traffic calming measure Radar speed camera Urban area Road safety Rural roads Pedestrian Crosswalk Traffic calming measures (TCMs) are implemented in urban areas to reduce vehicles’ speed and, generally speaking, results are obtained. However, speed is still a problem in rural roads crossing small villages without a bypass and with short-length urban areas, since drivers do not normally reduce their speed for that short segment. Hence, various TCM can be installed. It is necessary to maintain a calm area in these short segments to improve road safety, especially for pedestrian aiming to cross the road, and to save combustible by avoiding a constant increase-decrease of speed. Four villages were selected to evaluate the efficiency of radar speed cameras and panels indicating vehicle’s speed. Results showed that the presence of radar speed cameras reduces the speed in the direction they can fine, but with a lower effect in the non-fining direction. Additionally, a positive effect was observed in the fining direction in other points, such as pedestrian crossings. Nevertheless, the effect does not last long and speed cameras may be considered as punctual measures. If the TCMs are placed far from the start of the village they are not respected. Hence, it is recommended to place them near the real start of the build-up area. Lastly, it was verified that longer urban areas make overall speed decrease. However, when drivers feel that they are arriving to the end of the urban area, due to the inexistence of buildings, they start speeding up. 2023-04-20 2023-04-20 2021-12 info:eu-repo/semantics/article http://hdl.handle.net/10259/7650 10.3390/en14238146 1996-1073 eng Energies. 2021, V. 14, n. 23, 8146 https://doi.org/10.3390/en14238146 info:eu-repo/grantAgreement/GIRDER//2019.0478/ info:eu-repo/grantAgreement/Ministry of Science and Higher Education//WZ%2FWB-IIL%2F1%2F2020/PL/ http://creativecommons.org/licenses/by/4.0/ info:eu-repo/semantics/openAccess Atribución 4.0 Internacional MDPI
