Mongolia in context: Street-network sprawl of new development

The level of street-network sprawl in new development in Mongolia rose steadily. To get a sense of how street development has changed in Mongolia, we can consider two of its most populous regions: Ulaanbaatar and Orhon. None of the most populous cities follow the same trend as the region. The level of street-network sprawl in new development in Ulaanbaatar peaked in 1976-1990. The level of street-network sprawl in new development in Orhon followed a zig-zag trend with an overall decrease.

The largest city in Mongolia is Ulaanbaatar, with a population of 1231400 people. Taking into account the entire (i.e. aggregate) street network in Ulaanbaatar as of 2020, the overall level of street-network sprawl is 4.51, which is sprawly. The level of street-network sprawl in new development in Ulaanbaatar peaked in 1976-1990.

Mongolia in context: Aggregate street-network sprawl

As of 2020, the city with the most disconnected street network in Mongolia is Ulaanbaatar with an SNDi of 4.51, which is sprawly. Conversely, the most connected city is Erdenet with an SNDi of 2.09, which is well-connected. See these two cities’ trends in the above graph, or dive deeper into each: Erdenet, Ulaanbaatar.

The level of street-network sprawl in the aggregate network in Mongolia rose steadily. To get a sense of how the aggregate street network has changed in Mongolia, we can consider two of its most populous regions: Ulaanbaatar and Orhon. Out of the two regions, Orhon does not follow the same trend as the country. The level of street-network sprawl in the aggregate network in Orhon fell steadily.

The largest city in Mongolia is Ulaanbaatar, with a population of 1231400 people. Taking into account the entire (i.e. aggregate) street network in Ulaanbaatar as of 2020, the overall level of street-network sprawl is 4.51, which is sprawly. The level of street-network sprawl in the aggregate network in Ulaanbaatar rose steadily.
