PREDESIGN RATIONALE CONSTRUCT REGIONAL ROAD NETWORK
The problems affecting the formation of an optimal road network development program most relevant of which is the old typology network of federal and regional roads. In most cases, the mark of the network has a pronounced radial structure with an insufficient number of connecting roads and chordates, missing road links between neighboring regions of the Russian Federation for the shortest lines. In addition, the lack of bypasses around major population centers, which permit transit traffic carried on the road network, which increases the vibration loads on buildings and structures, as well as degrade the environment. The essential problem is the strength of the existing pavement of the road network, which reduces the design speed of the road transport and increases the number of road accidents.
