The constant development of transport systems and the extensive activities related to the safety of its users necessitate the development of methods for assessing the impact of road infrastructure expansion/modernization on road safety. The objective of this paper is to elaborate the concept of such an assessment, which will form part of the author’s activities aimed at creating a methodology for a comprehensive analysis of the operational reliability of transport systems. The concept of assessing the impact of road infrastructure development on road safety presented in this paper refers to the GAMAB and Road Safety Impact Assessment methods from the subject literature. Our method is based on a comparative analysis of the condition of road infrastructure before and following its expansion/modernization, based on commonly available data, which constitutes the main advantage of the concept presented in this paper. Furthermore, the coefficients for occurrence of adverse road events were determined, and then conclusions drawn on this basis. The acquired results constitute an argument for the correctness of the presented concept.
