This article considers the issues of dynamics of road safety provision systems in three multiscaled systems (Russia, Siberian Federal Okrug or SFO and separate regions of SFO). The indicator of relative information entropy Hn of road safety provision process was taken as the characteristic of system orderliness. The ideology, methodic and results of quantitative assessment of road safety provision systems information entropy H were considered. Time series of modification of relative information entropy Hn of road safety provision systems in 2004.. .2018 in Russia, Siberian Federal Okrug and individual subjects of SFD were presented. Special attention was paid to consideration of the re-searched process in the Republic of Tuva. This region is characterized by nonstandard, different from general trend dynamics of information entropy H of road safety provision system. The general conclusion of the article is that during last 15 years information entropy of road safety provision systems significantly decreased, i.e. orderliness of formation process of road traffic participants safety greatly increased. However, results achieved in this sphere by Siberian regions are still far from best world results.

“…Specific methods of estimation of entropy of human-technological systems in relation to issues of road safety formation and public transport transportation process were considered in works [11,12,13]. By using this baseline, cause-and-effect chain of formation of CPPT functioning results can be presented as in fig.…”

“…Every unit of informational transformation process forms operator -reducing coefficient Ki, characterizing relative decrease of number of citizens corresponding to every unit of chain [11,12,13]. For example, 1,6 million daily transport movements of Tyumen citizens include nearly 400…450 thousand CPPT movements (in the period of «selfisolation» value decreased to 100…150 thousand movements).…”

“…Entropy characterizes quantitative estimation of information loss during the process of passing it in the channel [3 -10]. Consequently, entropic analysis is convenient instrument for estimation of quality of production-technological processes management [11,12,13]. It can be applied to estimation of quality of passengers' transportations management.…”

This article presents approaches to estimate orderliness of transport service of large city by means of city passenger public transport (CPPT). An article considers entropic analysis method as main analytical instrument of orderliness of transportation process. Author presents cause-and-effect chain of formation of results of transportation process by CPPT and process of informational transformation during transportation. An article gives an example of calculation of relative entropy of transportation process by CPPT in Tyumen during March-September 2020. Additional attention was paid to changes of orderliness of transport service during the acute phase of pandemic COVID-19 (April-June 2020). It was established that relative entropy of transportation process decreased during acute phase of pandemic COVID-19 in comparison to periods of sustainable functioning of CPPT system. Respectively orderliness of transportation process increased at the same time. This fact can be explained by structural changes of volume of transported passengers (total volume of traffic – volume of transportation of preferential passengers – volume of transportation of senior citizens). By the results of research author made conclusions and gave recommendations on possible increasing of orderliness of CPPT transportation process.

“…Studies [13] show that sharp improvement of level of traffic safety has become possible in Russian cities with a population of more than 1 million people because of increase in attention of the state to questions of people's life quality in recent years. The analysis of the process of transformation of living conditions of the people in the safety performance of traffic dedicated to the articles [14]. Articles [15] are devoted to assessment of spatial features of road and transport accident rate in regions of Russia.…”

The article examines the issues of assessing the sustainability of road safety improvement process in Russian cities with a population of more than 1 million people. In 2015...2018 a sharp decrease in the overall level of road traffic accidents in the Russian Federation was recorded. However, in different regions and cities of the country this positive process runs extremely heterogeneously, with various speeds and different levels of qualitative changes in the field of road safety. The T-Wilcoxon criterion is an instrument, used in analyzing accident rate statistics, which can help in the argumentation of the opinion on the sustainability of this process or, vice versa, on the chaotic state and weak expression. On the example of accident rate statistics in Russian cities with a population of more than 1 million people, the article proves that improvement of road safety can be characterized as sustainable.
