Context Poland is covered by the automatic traffic enforcement system. Since road safety improvement progress in Poland is slow, it was decided to expand this system.

Process In 2019, a methodology was developed to optimize the selection process of recording devices locations, including enforcing the exceeding of speed limits and entering the intersections at red light. By using more technologically advanced recording devices, road network covered by automatic enforcement system has been expanded.

Analysis The available data regarding locations of accidents and collisions was collected. Data was verified and superimposed on country map, broken down into accidents’ types. Data on accidents included their severity due to exceeding the speed limit, not maintaining a safe distance between vehicles, non-compliance with traffic lights etc. Spatial and multifactorial analyses were carried out as well. The maps were divided into areas and the degree of risk for each area was assessed. Each area was evaluated with regard to different weights, assigned according to events’ severity and type. Methods for determining the intensity of traffic incidents and algorithms for creating ranking lists were developed. Based on that, specific areas were selected for further analyses.

Outcomes Based on the carried out analyses, locations for new recording devices were selected, ranking list of locations and risk maps were developed for all road types.

Learning Outcomes The new approach to the process of locations’ selection of the recording devices is easy to implement and will contribute to the optimization of this process and, consequently, to road safety improvement.
