The chart above shows the evolution of street network disconnectedness of the most connected and most disconnected cities in Gabon, for both new street additions (left) and the aggregate street network (right).
Gabon in context: Street-network sprawl of new development
The level of street-network sprawl in new development in Gabon peaked in 1976-1990. To get a sense of how street development has changed in Gabon, we can consider three of its most populous regions: Estuaire, Haut-Ogooué and Ogooué-Maritime. None of the most populous cities follow the same trend as the region. The level of street-network sprawl in new development in Estuaire peaked in 1991-2005. The level of street-network sprawl in new development in Haut-Ogooué peaked in 1991-2005. The level of street-network sprawl in new development in Ogooué-Maritime followed a zig-zag trend with an overall increase.
The largest city in Gabon is Libreville, with a population of 661400 people. Taking into account the entire (i.e. aggregate) street network in Libreville as of 2020, the overall level of street-network sprawl is 6.11, which is very sprawly. The level of street-network sprawl in new development in Libreville peaked in 1991-2005.
Gabon in context: Aggregate street-network sprawl
As of 2020, the city with the most disconnected street network in Gabon is Franceville with an SNDi of 6.32, which is very sprawly. Conversely, the most connected city is Port-Gentil with an SNDi of 2.31, which is well-connected. See these two cities’ trends in the above graph, or dive deeper into each: Port-Gentil, Franceville.
