How we measure street-network sprawl
The 4 dimensions of SNDi
- Nodal degree: the number of streets meeting at each intersection
- Dendricity: the tree-likeness of the network (dead ends and cul-de-sacs)
- Circuity: the ratio of road distance to straight-line distance between two points
- Sinuosity: the curviness of individual streets
A higher SNDi means less-connected streets – i.e., more sprawl.
