The chart above shows, for each construction period in the Salta region, the SNDi of new street additions (bar height) and the volume added (bar width), so that bar area reflects the total disconnectedness burden of that period's construction. The 1975 period contributed the greatest disconnectedness burden, with 2,900 km of street added at an SNDi of 2.06. Overall, the SNDi of new street additions in the region followed a zig-zag trend with an overall increase.
How have Salta's street networks changed over time?
Most recent snapshot
Taking into account the entire (i.e. aggregate) street network in Salta as of 2020, the overall level of street-network sprawl is 2.16, which is well-connected.
Trends in street network construction
The SNDis of street construction for the respective time periods are 2.06, 3.06, 2.11 and 2.22. Disconnectivity in street construction in Salta follows a zig-zag trend. In 1975, street construction was most disconnected, while construction was most connected in 1976-1990.
Quantity of street network construction
The street network in Salta spans a total of 4,900 kilometers. It is dominated by roads constructed prior to 1975. These roads have an SNDi of 2.06, which is well-connected.
Effect 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. Therefore, it has a limited effect on the street network as a whole. The SNDis of the aggregate street network in the respective time periods are 2.06, 2.15, 2.14 and 2.16. Disconnectivity in Salta's street network follows a zig-zag trend. In 1975, the region was most disconnected; while it was most connected in 2006-2020.
