Valle de Santiago in context: Street-network sprawl trends

The chart above shows SNDi trends for new street additions (left panel) and the entire network (right panel), with Valle de Santiago plotted against Guanajuato and México. All three follow the same trend in new construction, suggesting a shared regional pattern of development. Most recently, Valle de Santiago's incremental SNDi rose from 2.66 to 3.17 between 1991-2005 and 2006-2020.

In new street additions, Valle de Santiago fluctuated in its street-construction patterns, while Tirumangalam built increasingly disconnected streets from 1975 through 1991-2005, then improved and Xikou built increasingly disconnected streets over time. For the full street network, though, all three cities follow the same trend. Notably, Valle de Santiago had a more sprawly network than Xikou in 1975 but the two have since reversed their relative ranking.
