China in context: Street-network sprawl of new development

The level of street-network sprawl in new development in China followed a zig-zag trend with an overall increase. To get a sense of how street development has changed in China, we can consider three of its most populous regions: Guangdong, Shandong and Jiangsu. Out of the three regions, Shandong and Jiangsu do not follow the same trend as the country. The level of street-network sprawl in new development in Shandong peaked in 1976-1990. The level of street-network sprawl in new development in Jiangsu peaked in 1976-1990.

The largest city in China is Guangzhou, with a population of 39136200 people. Taking into account the entire (i.e. aggregate) street network in Guangzhou as of 2020, the overall level of street-network sprawl is 3.37, which is relatively sprawly. The level of street-network sprawl in new development in Guangzhou followed a zig-zag trend with an overall increase.

China in context: Aggregate street-network sprawl

As of 2020, the city with the most disconnected street network in China is 夔门街道 with an SNDi of 13.01, which is very sprawly. Conversely, the most connected city is Qianjin with an SNDi of 0.85, which is very well-connected. See these two cities’ trends in the above graph, or dive deeper into each: Qianjin, 夔门街道.

The level of street-network sprawl in the aggregate network in China rose steadily. To get a sense of how the aggregate street network has changed in China, we can consider three of its most populous regions: Guangdong, Shandong and Jiangsu. Out of the three regions, Guangdong does not follow the same trend as the country. The level of street-network sprawl in the aggregate network in Guangdong followed a zig-zag trend with an overall increase.

The largest city in China is Guangzhou, with a population of 39136200 people. Taking into account the entire (i.e. aggregate) street network in Guangzhou as of 2020, the overall level of street-network sprawl is 3.37, which is relatively sprawly. The level of street-network sprawl in the aggregate network in Guangzhou rose steadily.
