Review article

The paper presents a technique of calculating the network of Compressed Natural Gas Stations (CNGSs) for the main consumers of gas motor fuel in Saint-Petersburg. The prospects of creating such network are discussed. Based on the analysis of the raw data (average daily vehicle mileage, average daily fuel consumption, rate of release to the line, etc.) relating to bus fleets and "Spetstrans" enterprises, there have been done calculations of their requirements in natural gas for the period up to 2020. A mathematical apparatus is proposed for the creation of CNGSs rational network with the purpose minimizing of the route length to the filling station for dual fuel vehicles. A graphical model of the corresponding infrastructure is submitted.
