The analysis of traffic safety on the intersections of roadways and tram tracks

Ensuring high standard of service of public transport is among the most important goals of sustainable mobility. One of the most promising subsystems of public transport in this respect is the tram transport. Trams are eco-friendly and able to transport large numbers of passengers. However, in order to shape an efficient tram system, it is important to minimize the possibility of occurrence of incidents involving trams and road vehicles at intersections of roadways and tram tracks. The paper presents a proposition of a method of analysis of incidents in such locations. For ensuring a comprehensive approach to safety problem, the analysis encompasses two aspects: temporal and spatial. The proposed method has been presented on the example of tram network of the Metropolis GZM (Metropolitan Association of Upper Silesia and Dąbrowa Basin) area. The analysis has enabled identification of causes of incidents for the two most hazardous intersections of roadways and tram tracks. For each of these locations, proposed solutions to improve the level of safety have been determined.
