- As statistical analyses conducted by The National Police Headquarters indicate, pedestrian crossing which is supposed to be a safe place for unprotected participants of road traffic is an area where about 10% of road accidents occur in which at least 3500 persons are injured, and over 200 die annually. Despite constant development of road infrastructure in Poland, this situation fails to improve in the expected way. Several reasons of this state of affairs can be detected. Undoubtedly a decisive factor in pedestrian safety at night-time is ensuring the drivers proper observation conditions of pedestrian crossings. The article will present assessment of lighting of pedestrian crossings making use of Small Target Visibility model. Due to the use of luminance and contrast criterion, it is possible to assess visibility level - a key parameter responsible for perception of a pedestrian by a driver on pedestrian crossings. Graphic chart showing accidents with pedestrian participation in the European Union, target for visibility research by means of STV method on pedestrian crossing, visibility level VL by means of STV method, Location of objects on pedestrian crossing by means of STV method, pedestrian crossing illuminated by lighting frames, visibility level on pedestrian crossing obtained as a result of lighting frames illumination from the first and second observation direction are presented in the paper.
