The chart above shows, for each construction period in México, 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 2006-2020 period contributed the greatest disconnectedness burden, with 95,500 km of street added at an SNDi of 4.38. Overall, the SNDi of new street additions in México followed a zig-zag trend with an overall increase.
How have México's street networks changed over time?
Most recent snapshot
Taking into account the entire (i.e. aggregate) street network in México as of 2020, the overall level of street-network sprawl is 3.35, which is moderately connected.
Trends in street network construction
The SNDis of street construction for the respective time periods are 2.61, 3.71, 3.4 and 4.38. Disconnectivity in street construction in México follows a zig-zag trend. In 1975, street construction was most disconnected, while construction was most connected in 2006-2020.
Quantity of street network construction
The street network in México spans a total of 400,900 kilometers. The period with the greatest volume of street construction was 1975. These roads have an SNDi of 2.61, which is relatively 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 2.61, 2.89, 3.06 and 3.35. Overall, the SNDi of the aggregate street network has risen: the street network in México has become more disconnected.
