Formation of the transport system of the astrakhan region during the construction of the northern bypass of the international transport corridor “north - south”

The article highlights the importance of the international transport corridor “North - South” for our country. It is important to consider that the Astrakhan region is a gateway to international transport links. Both water and road routes, which are part of the North-South ITC, pass through the city of Astrakhan and the Astrakhan region. Road communication routes are extremely in demand due to the multimodality of cargo transportation, as well as the decrease in volumes when using waterways due to the shallowing of the Volga-Caspian Canal. Existing road transport routes pass through the urban environment, significantly increasing the traffic load. This leads to a deterioration in the condition of the road surface, negatively affects the economic and environmental components, and there is an increase in the number of congestion conditions. To improve the efficiency of the North-South international transport corridor, planning solutions have been developed. The planning task was to redirect transit traffic flows in order to divert them from the city, reducing the length of road communications. The implementation of planning solutions was carried out using the PTV Vision® VISSIM software product. The article presents the developed scheme of an alternative route, implemented through the construction of the Northern Bypass, which includes the construction of a new bridge across the Volga River, as well as road interchanges. This planning solution will allow the length of road communications, which are a regional part of the international transport corridor “North-South,” to be halved. If implemented, the proposed project will relieve congestion on the highways of the city of Astrakhan, increase traffic capacity and traffic safety.
