Kaya 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 Kaya plotted against Centre-Nord and Burkina Faso. The SNDi of new construction in Kaya was at its lowest in 1976-1990, compared to Centre-Nord which was at its lowest in 1991-2005 and Burkina Faso which followed a zig-zag trend with an overall increase. Most recently, Kaya's incremental SNDi rose from 2.14 to 4.17 between 1991-2005 and 2006-2020. In terms of the aggregate network, Kaya ranked 1st out of 1 cities in Centre-Nord and 19th 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, Kaya built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns, while Kundapura built increasingly disconnected streets over time and Lafayette built increasingly disconnected streets from 1975 through 1991-2005, then improved. Looking at the full network, Kundapura and Lafayette both became progressively more disconnected, while Kaya became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards. Notably, Kaya had a more connected network than Lafayette in 1975 but the two have since reversed their relative ranking.
