Guinea in context: Street-network sprawl of new development
The level of street-network sprawl in new development in Guinea rose steadily. To get a sense of how street development has changed in Guinea, we can consider three of its most populous regions: Conakry, Kankan and Nzérékoré. Out of the three regions, Kankan does not follow the same trend as the country. The level of street-network sprawl in new development in Kankan followed a zig-zag trend with an overall increase.
