Resumen
The article, according to the concept of urban sustainable development, proposes street classes that are absent in the Russian standards: urban boulevards, transit friendly streets and the so-called shared space. The results of the comparative analysis of road network classification systems in different countries are given, on the basis of which we have proposed a list of criteria that make a basis of road network classification; the peculiarities of the design of the proposed street classes are discovered. Using the example of the central part of Irkutsk, we conducted an audit of street space. In view of the proposed streets classes, we proposed measures to reform the road network of the study area. In the new network we estimated the traffic demand and the redistribution of traffic flows. The simulation results show a significant decrease in inter-regional transit flows of individual transport in the central part of the city.
