When arranging the pedestrian infrastructure, one of the most important components that make a tangible contribution to the safety of pedestrians is to organize safe road crossing. At the same time, in cities, there is of-ten a tendency for pedestrians to cross a road in the wrong place due to established routes or inadequate location of pedestrian crossings. Acci-dents with the participation of pedestrians who crossed the road in viola-tion of traffic rules, make up a significant part of the total amount of road accidents. In this paper, we propose a method that allows us, on the basis of the results of a computer simulation of pedestrian traffic, to ob-tain predicted routes for road crossing and to indicate optimal locations for pedestrian crossings that take into account established pedestrian routes and increase their safety. The work describes an extension for the existing AntRoadPlanner simulation algorithm, which searches for and clusters points where pedestrians cross the carriageway and suggests loca-tions for new pedestrian crossings. This method was tested on the basis of a comparative simulation of several territories before and after applying the method, as well as on the basis of a field study of the territories. The developed algorithm can also be used to search for other potentially dan-gerous places for pedestrians on plans of districts, for example, crossings in places with limited visibility.
