ON THE ISSUE OF ASSESSING THE EFFECTIVENESS OF DESIGN SOLUTIONS TO ENSURE THE SUSTAINABILITY OF THE URBAN TRANSPORT SYSTEM

Abstract

Modern transport problems in many cities around the world are caused by the high level of motorisation of their population and the high frequency of private car use. Despite a number of advantages of using private cars as a means of transport (high speed of communication, the ability to choose a route and travel at a convenient time, high comfort, etc.), the mismatch between the development of motorisation and the existing transport infrastructure leads to traffic congestion, which has a number of negative consequences that make the use of private cars less efficient. These consequences include increased transport delays, reduced traffic speeds and, consequently, increased travel time, and more intensive consumption of non-renewable energy sources. Equally urgent are the issues of road safety and improving the environmental situation in cities. At present, a promising way to solve urban transport problems is to apply the concept of sustainable development of urban transport systems and the methodology of transport demand management.
The justification of design solutions to ensure the sustainability of urban transport systems should be based on a model approach and include a comprehensive assessment of a number of social, economic and environmental performance indicators. The adequacy of transport models and the accuracy of the assessment of the consequences of design decisions are crucial for choosing the most appropriate set of measures to ensure the sustainability of transport systems.
The article proposes an efficiency criterion for evaluating design solutions to ensure the sustainability of the city's transport system, which contribute to reducing the use of private car. This criterion provides for a comprehensive assessment of the effectiveness of design solutions in terms of economic, social and environmental performance indicators.
Based on the analysis of statistical data, it was found that the following distribution of passenger cars by type of fuel consumed is typical for Kharkiv: cars with petrol engines - 48.58%; diesel cars - 14.63%; cars with gas cylinder equipment - 33.58%; electric cars - 3.21%. The established distribution of passenger cars by type of fuel consumed is the basis for establishing average values of variable and fixed operating costs of private car owners and should be taken into account when assessing the environmental impact of the transport process. This is the direction of further research.
