A unified approach for measuring the level of service of transport infrastructure

This article aims to discuss the problem of road traffic management and the criteria for its measurement. The article uses the concept of service level as the most important characteristic in the assessment of transport infrastructure. The differences in approaches to determining the level of service in the world practice are considered. The problem is outlined of non-uniform metrics used to measure the level of service for various road elements in existing methodologies. A comparison is made of the assessment of the level of service of a traffic lane in the Russian and foreign approaches in the choice of coefficients and the method of their calculation. Changes are proposed to the existing Rosavtodor methodology for assessing the capacity of a lane, a roundabout, an unregulated and regulated intersection, which can simplify the assessment of the level of service. As a result, an example of the application of the proposed unified approach in calculating the capacity of a controlled intersection is given. Finally, a conclusion is drawn about the need for a new approach, the advantages of using unified metrics for the level of service assessment are highlighted, and the vector of future research on this problem is also outlined.
