Mapping and analysing road accidents involving vulnerable road users in the City of Zagreb

Pedestrians and cyclists are the most vulnerable road users, and thus belong to the so-called vulnerable road user group, together with the motorcyclists, who demand special attention in order to increase the level of their safety. In the Republic of Croatia, three quarters of the total number of road accidents occur in the urban environment, in which two thirds of the total number of casualties are pedestrians and cyclists. The causes of the significant number of road accidents and the general picture of pedestrian and cyclist safety in the urban road network are incomplete and unsystematic data collection and their partial analysis. Therefore, this requires additional research in the scope of road safety and the general level of service in the road network. The goal and the purpose of the paper is, based on the available data, to make a high-quality and a high-quantity road accident analysis for pedestrians and cyclists in the road network of the City of Zagreb. Using modern computer techniques (modern software tools), it is possible to detect and significantly improve road safety.
