With the global surge in urban mobile populations, the demand for efficient public transport systems has intensified. This article explores the factors influencing the expansion of public transport networks, including increased state subsidies, growing fuel consumption, and the imperative to manage transportation costs. The focus lies on optimizing the utilization of transport networks to curtail expenses through the introduction of the Useful Work Coefficient (UWC) as an efficiency metric. Despite previous scientific research on urban transport efficiency, critical questions remain unanswered. The article delves into inquiries concerning the rationality of existing transport types, the optimization of routes and networks, and the alignment of transport systems with the populace's needs. Traditional statistical data on route lengths, types of transport, rolling stock metrics, and passenger volumes prove
insufficient in providing comprehensive answers. The assessment of urban passenger public transport efficiency involves a complex interplay of various indicators such as price, profit, and revenue. However, the absence of a standardized evaluation unit poses challenges. Recognizing the need for a multi-criteria approach, the article argues for the integration of social and economic factors in evaluating efficiency.
