GEOSPATIAL ANALYSIS OF TRAFFIC ACCIDENTS IN URBAN AREAS - CASE STUDY OF CITY OF SISAK

Common issues affecting urban areas are traffic jams and the safety of road traffic, both of which are the consequence of the excessive usage of private cars. A large number of pedestrians and cyclists in urban traffic, specific features of the urban area, insufficient education and training of road users, as well as unregulated infrastructure, play a part in making public safety a growing issue in urban areas. The paper is primarily concerned with the analysis of road traffic accidents in the urban area of the City of Sisak, which is carried out using the geographic information system (GIS). The analysis offers an insight into the information concerning dangerous areas of road network, thus enabling the identification of areas which pose a higher risk and the proposition of suitable countermeasures in order to create a safe environment for road users and improve safety. In addition, the paper gives insight into a survey which estimates the subjective perception of safety of road users in the city of Sisak. Moreover, the paper includes a statistical analysis of the data processing on traffic accidents based on national database of the Ministry of the Interior. Furthermore, the paper also comprises measures such as the removal of problematic areas by introducing a new regulation of traffic flow organisation in the city centre, as well as indicators which have to be monitored on a yearly basis in order to increase the safety of all citizens in urban areas.
