Abstract
This paper, as a part of a series of researches focusing on relationships between organizational structures of urban public transport and entire urban transport systems, focuses on how to describe and typify the organizational structure. With a literature review taken into consideration, a diagram is developed to describe organizational structures. Then, using this, structures of four cities, namely London, Vienna, Tokyo, and Soul, are described. Following this, three typologies are derived from the structures in the four cities. At the end, brief discussions related to the main focus of the research - relationships between the organizational structure and transport systems - are made.
