Numerical data have been presented, and separated into road accidents and collisions as well as injured and fatalities. The age and sex characteristics of the perpetrators of road accidents were presented. The QGIS program was also used for the analysis, which allowed us to map the most dangerous intersections in Sosnowiec.

Abstract. The article addresses solutions implemented in two cities, namely, Mexico City and Katowice, with the aim of improving road traffic safety. Despite the distance of more than 10,000 km separating the two cities, a comparison revealed many similar solutions having been implemented in both of them. This comparative case study is complemented with a collation of statistics pertaining to accidents, fatalities and injured persons as reported in the period 2012-2015.
