Shpuza; Urban Shapes and Urban Grids: A Comparative Study of Adriatic and Ionian Coastal Cities

small holes caught up in the process of city’s expansion with radial and ring roads (Doxiadis 1968). Taylor argued that puncturedness is one of the main contributors affecting the distribution of distances in shapes. Experiments with theoretical shapes modified systematically and two hypothetical layouts generated in them have shown that the effect of shape holes upon the layout Integration is exerted according to shape regions (Shpuza 2006, Shpuza and Peponis forthcoming). Therefore, in order to gauge the effect of shape holes on the syntactic p r o p e r t i e s o f u r b a n g r i d s , t h e h u l l s o f u r b a n s h a p e s a r e a n a l y z e d ( ) v i , F c o n v e x according to six measures of Drelative () and Fvisual () and their

Skewness as well as the percentage of the area of holes to the area of the overall shape hull (table 1). The argument later on clarifies how the six measures for both actual shapes and shape hulls are related to the Integration of urban grids.

The statistical co-variations among shape measures are used to search for relational patterns between compactness and fragmentation in urban form. The measures of Convex Fragmentation
