Review article

This article considers the issues of dynamics of organizing the road safety provision systems in three multi-scaled systems - Russia, Northwest Federal District (NWFD) and some individual Northwestern regions, referring to the period from 2004 to 2018. As the characteristic feature of the system organizational structure there was used the indicator of relative information entropy Hn of road safety provision process. The ideology, method and results of the quantitative assessment of information entropy of Hn systems aimed at road safety provision were considered. Time modification series of relative information entropy Hn of road safety provision systems in the period from 2004 to 2018 in Russia, Northwest Federal District, Leningrad region and Saint Petersburg are presented. The general conclusion of the study is that during the last 15 years in the specified districts, as well as in Russian Federation as a whole, information entropy of road safety provision systems has significantly decreased, i.e. the organizational structure of road traffic safety provision for the participants of road traffic has considerably increased.
