Aassessment of visibility on pedestrian crossing - computational model

Piotr Tomczuk

Abstract

As statistical analyses conducted by The National Police Headąuarters indicate, pedestrian crossing which is supposed to be a safe place for unprotected participants ofroad traffic is an area where about 10% ofroad accidents oceur in which at least 3500 persons are injured, and over 200 die annually. Despite constant development ofroad mfrastructure in Poland, this situationfails to improve in the expected way. Severalreasons ofthis state ofaffairs can ie detected. Undoubtedly a decisive factor in pedestrian safety at night-time is ensuring the drivers proper obseryation conditions of pedestrian crossings. The article will present assessment oflighting of pedestrian crossings making use of Smali Target Yisibility model. Due to the use of luminance and contrast criterion, it is possible to assess yisibility 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, targetfor visibility research by means of STV method on pedestrian crossing, yisibility level VL by means of STV method, Location ofobjects on pedestrian crossing by means ofSTV method, pedestrian crossing illuminated by lightingframes, yisibility leyel on pedestrian crossing obtained as a result oflightingframes illuminationfrom thefirst and second obseryation direetion are presented in the paper
