Lighting requirements for pedestrian crossings – positive contrast

Abstract

For many years now in Poland there has been a large number of road accidents at pedestrian crossings during night periods [5, 11]. One of the technical solutions that can improve this condition is the use of proper lighting for pedestrian crossings. The designated pedestrian crossing should be visible in different weather conditions and at different times of the day. In case of night vision restrictions use artificial lighting of pedestrian crossings. At the same time, lighting of pedestrian crossings should ensure: proper conditions for the driver to recognise the traffic situation and observe the pedestrian's silhouette, and for the pedestrian to observe the surroundings, pedestrian crossings and upcoming vehicles. The article gives an opinion on the proposal of lighting requirements for dedicated luminaires, realizing positive luminance contrast, used in the area of pedestrian crossings together with the proposed measurement grids. Quantitative requirements have been formulated taking into account the gradation of lighting classes resulting from the current lighting standard.
