Chile in context: Street-network sprawl of new development
The level of street-network sprawl in new development in Chile followed a zig-zag trend with an overall increase. To get a sense of how street development has changed in Chile, we can consider three of its most populous regions: Santiago Metropolitan, Valparaíso and Bío-Bío. Disconnectivity in the most populous cities in Chile follow the same country trend.
