Tenkodogo 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 Tenkodogo plotted against Centre-Est and Burkina Faso. All three follow the same trend in new construction, suggesting a shared regional pattern of development. Most recently, Tenkodogo's incremental SNDi rose from 1.52 to 1.97 between 1991-2005 and 2006-2020. In terms of the aggregate network, Tenkodogo ranked 1st out of 3 cities in Centre-Est and 7th out of 19 in Burkina Faso as of 2020.

Rankings go from most connected to most disconnected — rank 1 is the most connected.

In new street additions, Tenkodogo fluctuated in its street-construction patterns, while Yangxi built increasingly disconnected streets over time and Kavali built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns. For the full network, Tenkodogo and Yangxi both became progressively more disconnected, while Kavali became more connected from 1975 through 1991-2005, then grew more sprawly from 1991-2005 onwards. Notably, Tenkodogo had a more sprawly network than Yangxi in 1975 but the two have since reversed their relative ranking.
