ABSTRACT
The geographical information system (GIS) is a powerful tool for analyzing networks, which are often characterized by their nodes (intersections) and edges (links between neighboring intersections), as well as the attributes attached to them. This representation of networks can be useful for analyzing modern street networks that have rather straight roads. On the other hand, traditional street networks possess certain features that are different from those in cities having a modern street network system. Typical of these features are an abundance of “organic” networks having a large number of dead-ends, curvy and narrow roads (on the human scale), and a lack of main streets. Some of these features may need more sophisticated measures to characterize them.
