Resumen
On the basis of the literature review and secondary research results presented in the article, it should be stated that the continuous modernization of the rolling stock used to provide collective urban transport services is one of the main tools to encourage urban residents to abandon the use of passenger cars for collective transport. In order to make the rolling stock modernization process as smoothly as possible, it is necessary to carry out and then settle tenders for city buses. In the article, the primary research on the criteria used to evaluate offers in tender procedures for city buses in Poland was presented using descriptive statistics. The article also attempts to discuss whether the current weightings of the price criterion and non-price criteria reflect their share in the total cost of the life cycle of the city bus.
