This article attempts to assess the diversity of road infrastructure in Poland by regions. The article takes into account the length of roads, expenditure on public roads, the volume of passenger and freight transport, and traffic congestion in individual provinces. The data obtained were compared with information on road safety including the number of accidents and people injured on the roads. Conducted multivariate statistical analysis of road infrastructure diversity indicates that the Silesian, Mazovian and Lesser Poland Voivodeships have the most developed road infrastructure in Poland, while it is the least developed in the West Pomeranian, Warmian-Masurian, Lublin and Podlaskie Voivodeships. Moreover, a very strong relationship was also observed between the development of road infrastructure and the number of injuries and deaths in individual provinces. The analysis of the structure of accidents shows that it is necessary to invest in highways and motorways in the eastern provinces where the number of deaths is the highest.
