The study examines to what extend the public transport users are satisfied with the service in Budapest. The unrepresentative survey was carried out electronically. The study was meant to be the starting point for the next milestone of the research in which, by using the results of this study and assessing the relative significance of the most important factors, we can make proposals for the decision makers for specific intervention points. Furthermore, this article, as part of a doctoral thesis of one of the discoursers aims to provide assistance to create an assessment system for the public transport service providers. For today we already know that a sustainable metropolis can only exist with sustainable public transport and a fundamental condition for this is that the number of passengers must not fall. It needs investments like any other sectors economic sectors and the first step is to be aware of the expectation of users – here passengers –, which are the most crucial factors, what are the most important factors that make them choose public transport, and what are the factors that make them turn to other transport alternatives because of their absence or low quality. The research results show that respondents consider the following factors to be important: cleanliness and equipment of vehicles and stops, frequency of vehicles and their correspondence to the timetable, passenger information and barrier-free accessibility.
