The chart above shows the evolution of street network disconnectedness of the most connected and most disconnected cities in Sudan, for both new street additions (left) and the aggregate street network (right).
Sudan in context: Street-network sprawl of new development
The level of street-network sprawl in new development in Sudan followed a zig-zag trend with an overall increase. To get a sense of how street development has changed in Sudan, we can consider three of its most populous regions: Khartoum, North Darfur and South Darfur. Out of the three regions, North Darfur and South Darfur do not follow the same trend as the country. The level of street-network sprawl in new development in North Darfur was at its lowest in 1991-2005. The level of street-network sprawl in new development in South Darfur peaked in 1991-2005.
How do development practices in Sudan fare in comparison to others in the world? Most recently in 2006-2020, street construction in Sudan was the 2nd-most disconnected out of the 179 countries in the world. Its position in the ranks since 1975 has risen; relative to other countries in the world, street construction in Sudan has become more disconnected. Sudan ranked 8th in 1975, 4th in 1976-1990, 1st in 1991-2005 and 2nd in 2006-2020.
The largest city in Sudan is Khartoum, with a population of 5696400 people. Taking into account the entire (i.e. aggregate) street network in Khartoum as of 2020, the overall level of street-network sprawl is 1.43, which is very well-connected. The level of street-network sprawl in new development in Khartoum followed a zig-zag trend with an overall increase.
Sudan in context: Aggregate street-network sprawl
As of 2020, the city with the most disconnected street network in Sudan is Buram with an SNDi of 8.6, which is very sprawly. Conversely, the most connected city is Garsila with an SNDi of 0.84, which is very well-connected. See these two cities’ trends in the above graph, or dive deeper into each: Garsila, Buram.
The level of street-network sprawl in the aggregate network in Sudan followed a zig-zag trend with an overall increase. To get a sense of how the aggregate street network has changed in Sudan, we can consider three of its most populous regions: Khartoum, North Darfur and South Darfur. Out of the three regions, North Darfur and South Darfur do not follow the same trend as the country. The level of street-network sprawl in the aggregate network in North Darfur was at its lowest in 1991-2005. The level of street-network sprawl in the aggregate network in South Darfur rose steadily.
To date, Sudan is the 5th-most disconnected out of the 179 countries in the world. Its position in the ranks since 1975 has risen; relative to other countries in the world, the street network in Sudan has become more disconnected. Sudan ranked 8th in 1975, 7th in 1976-1990, 2nd in 1991-2005 and 5th in 2006-2020.
