Centre-Ouest: region in Burkina Faso
What exactly constitutes the spatial extent of the city? For these aggregations, we used the Global Human Settlement Layer Urban Center Database (GHS-UCDB) to define the boundaries of the city. These cities -- or urban centers -- cover areas that are densely populated and built-up, and so may extend beyond the spatial borders of these cities that we may be familiar with. The GHS area is shaded in blue.

Most recent snapshot: Taking into account the entire (i.e. aggregate) street network in Centre-Ouest as of 2014, the overall level of street-network sprawl is 1.25, which is relatively well-connected.
Trends in street network construction: The SNDis of street construction for the respective time periods are 0.37, 0.81, 1.92 and 1.37. Street construction in Centre-Ouest increased in disconnectivity initially but has since improved. The streets constructed in 1991-2000 were the most disconnected.
Quantity of street network construction: The street network in Centre-Ouest spans a total of 3966 kilometers. It is dominated by roads constructed in 2001-2014. These roads have an SNDi of 1.37, 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 0.37, 0.68, 0.96 and 1.25. Overall, the SNDi of the aggregate street network has risen: the street network in Centre-Ouest has become more disconnected. This increase has slowed: between 1975 and 1976-1990, SNDi rose by 0.3 points, but between 1991-2000 and 2001-2014, it rose by just 0.29.
The level of street-network sprawl in new development in Centre-Ouest peaked in 1991-2000. To get a sense of how street development has changed in Centre-Ouest, we can consider three of its most populous cities: Koudougou, Leo and Sapouy. None of the most populous cities follow the same trend as the region. The level of street-network sprawl in new development in Koudougou rose steadily. The level of street-network sprawl in new development in Leo followed a zig-zag trend. The level of street-network sprawl in new development in Sapouy followed a zig-zag trend.
