The safety of road network users is a fundamental goal of a modern transportation system. Safety is most commonly assessed by the number of traffic accidents and the severity of their consequences. In the Republic of Croatia, hazardous locations on the road network are continuously identified, and their remediation plays an important role in reducing the number of traffic accidents and mitigating their consequences. This paper analyzes the extent to which the processes of identifying and remediating hazardous locations have contributed to reducing the number of traffic accidents. The research includes a comparative analysis of a three-year period before and a three-year period after the implementation of remediation measures, with the objective of providing relevant insight into the effectiveness of the applied measures and their contribution to increasing road safety.

The analysis of each traffic accident is carried out based on recorded traces at the scene of the traffic accident and the damage caused to vehicles. One of the basic parameters in the analysis of traffic accidents is the mutual position of the vehicle at the time of the collision. To define the collision position of the vehicle, it is necessary to determine the intensity and compliance of the vehicle damage. The development of photogrammetry has enabled the creation of 3D models based on which the intensity and mutual compliance of vehicle damage can be more clearly shown, which increases the relevance of the determined collision position of the vehicle. Accordin gly, this paper will present the process of creating 3D models of damaged vehicles and will analyze all the possibilities of applying photogrammetry in defining the collision positions of vehicles.
