Kisaran in context: Street-network sprawl of new development Overall, the SNDi of the aggregate street network has risen: the street network in Kisaran has become more disconnected. The SNDis of the aggregate street network in the respective time periods are 3.01, 3.01, 3.14 and 3.74. Therefore, it has a limited effect on the street network as a whole. These roads have an SNDi of 3.01, which is in the 40th to 60th percentile of disconnectedness.Įffect on the aggregate network: New construction in each period adds to the total stock of streets, but does not change streets that have already been built. It is dominated by roads constructed prior to 1975. Quantity of street network construction: The street network in Kisaran spans a total of 213 kilometers. Trends in street network construction: The SNDis of street construction for the respective time periods are 3.01, nan, 6.55 and 6.88. aggregate) street network in Kisaran as of 2014, the overall level of street-network sprawl is 3.74, which is highly disconnected. Most recent snapshot: Taking into account the entire (i.e. To see the state of street-network sprawl across the globe, visit the

A global assessment of street-network sprawl.

Global trends toward urban street-network sprawl.

More information on the sprawl index can be found in these research papers: For the 10137 cities in our dataset, the average SNDi is 2.25, with half of the cities' SNDis falling between 1.08 and 3.25.

circuity, the ratio of the distance by road to the straight-line distance of two locations on the street networkĪ higher SNDi means less-connected streets – i.e., more sprawl.dendricity, the tree-likeness of the street network.

The SNDi is a comprehensive measurement of “sprawl”. SNDi - our measure of street-network sprawl (disconnectedness) We can quantify how connected street networks are with the Street Networkĭisconnectedness Index (SNDi). Sustainable consumption, social integration, and equity. Street network is associated with better outcomes for health, the environment, With more connected streets, residents drive less and walk more. The street network is permanent, and its connectivity affects the livabilityĪnd environmental footprint of cities for decades and centuries to come. Well-connected streets – like New York City’s grid – are more walkable

Less sprawl means more connected, more walkable Street-network Sprawl is a way to measure urban sprawl, worldwide, through
