This paper explores the application of the PC-Crash software package in the field of traffic accident reconstruction, with a particular focus on the analysis of digital tachograph records. Digital tachographs are modern tools used to automatically record key driving parameters, including speed, driver working hours, and distance traveled. They play a significant role in both traffic monitoring and the reconstruction of traffic accidents. PC-Crash, on the other hand, is one of the leading software solutions for simulating and analyzing traffic accidents, enabling precise reconstruction of events based on input parameters. This paper examines the use of PC-Crash software in the processing and interpretation of digital tachograph data, with the aim of enhancing the accuracy of analyzes and the objectivity of traffic incident reconstructions. The results demonstrate that the combined use of digital tachograph data and PC-Crash software significantly improves the reliability of reconstructions, which is of great importance to the judiciary, law enforcement, and traffic safety professionals.

The obstacle avoidance maneuver was the subject of many researches. Most of the models for calculation of distance necessary to perform the avoidance maneuver were based on theoretical researches, that took into account a large number of simplifications. In order to analyse the influence of different drivers and vehicles on a maneuver, an experimental research study of lane change was carried out at the test track which enables repeatability in the same conditions. Based on those researches it was established the empirical model for calculation of evasive maneuver distance. This model can be used for traffic accidents reconstruction, but also in the development concept of modern “intelligent” vehicles.

The usage of electric scooters (e-scooters) has experienced a real expansion in the territory of the Republic of Serbia in recent years. These vehicles represent an easy and simple way of transportation in city conditions, especially on shorter distances. The lack of legislative frameworks for this type of vehicle is the main problem in Serbia. That is why e-scooters are used according to the wishes and needs of users, which very often leads to unsafe situations. Research that includes the risky behaviors of e-scooters users is presented within this paper. The research of e-scooter users was conducted in the area of Novi Sad. The speeds of these vehicles at the selected locations were also measured during research.
