Looking at the literature, it appears that most of it focuses on the greenhouse gas emissions of transport, i.e. its environmental sustainability. However, little is said about the economic - and even less about the social - sustainability of transport. It is better to look at the broader concept of sustainability in order to take into account the opportunities, problems and sustainable solutions of the transport sector in a complex way.

For sustainable transport to be achieved, it is important that people use local public transport instead of private cars, but as long as its design and organisation - mostly due to political sensitivity - does not take into account the complex sustainability aspects of journey times, accessibility, safety, affordable prices and the perception of public transport, efforts will not achieve the desired goals.

The study does not aim to provide a comprehensive view of sustainability, but only to shed light on some aspects of sustainability in the field of public transport through an analysis of national and international literature.
