Network analysis is not a novelty in spatial statistics, however, in terms of data availability and data analysis techniques, there have been many developments in the recent years. Circuity is a quantitative indicator characterizing the transport network and the physical structure of the space in general, comparing the shortest distance in a straight line between any two points belonging to the network with the distance required to actually get there. Our research goal is twofold: (1) the development of a circuity calculation methodology based on numerous amount of road segment calculations, which exploits the potential inherent in the development of information technology in recent years and could reliably characterize the structure of each territorial unit; and with the developed methodology (2) the examination of (i) car, (ii) public transport and (iii) pedestrian networks in the internal areas of the Budapest districts where public transport is available. According to the analysis, driving circuity in Budapest's inner-city districts, and the public transportation circuity in its outer districts indicates a tendency for a higher additional travel demand compared to the distance in a straight line (sinuosity). In the case of the walking circuity, the coefficient values are more homogeneous, there are no particularly large differences compared to the average. The method could help spatial planning and the exploration of the relationships between the spatial structure and other socioeconomic indicators. [ABSTRACT FROM AUTHOR]
