Jiangsu: region in China
What exactly constitutes the spatial extent of the city? For these aggregations, we used the Global Human Settlement Layer Urban Center Database (GHS-UCDB) to define the boundaries of the city. These cities -- or urban centers -- cover areas that are densely populated and built-up, and so may extend beyond the spatial borders of these cities that we may be familiar with. The GHS area is shaded in blue.

Most recent snapshot: Taking into account the entire (i.e. aggregate) street network in Jiangsu as of 2014, the overall level of street-network sprawl is 2.58, which is in the 40th to 60th percentile of disconnectedness.
Trends in street network construction: The SNDis of street construction for the respective time periods are 1.97, 2.94, 2.59 and 2.6. Disconnectivity in street construction in Jiangsu follows a zig-zag trend. In 1975, street construction was most disconnected, while construction was most connected in 1976-1990.
Quantity of street network construction: The street network in Jiangsu spans a total of 134131 kilometers. It is dominated by roads constructed in 2001-2014. These roads have an SNDi of 2.6, which is in the 40th to 60th percentile of disconnectedness.
Effect on the aggregate network: New construction in each period adds to the total stock of streets, but does not change streets that have already been built. Therefore, it has a limited effect on the street network as a whole. The SNDis of the aggregate street network in the respective time periods are 1.97, 2.61, 2.6 and 2.58. The aggregate street network in Jiangsu increased in disconnectivity initially,but the trend has turned around after 1990.
The level of street-network sprawl in new development in Jiangsu followed a zig-zag trend with an overall increase. To get a sense of how street development has changed in Jiangsu, we can consider three of its most populous cities: Suzhou, Nanjing and Changzhou. Out of the three cities, Nanjing and Changzhou do not follow the same trend as the region. The level of street-network sprawl in new development in Nanjing peaked in 1991-2000. The level of street-network sprawl in new development in Changzhou was at its lowest in 1991-2000.
How do development practices in Jiangsu fare in comparison to others in China? Most recently in 2001-2014, street construction in Jiangsu was the 27th-most disconnected out of the 34 regions in China. Its position in the ranks since 1975 has risen; relative to other regions in China, street construction in Jiangsu has become more disconnected. Jiangsu ranked 28th in 1975, 22nd in 1976-1990, 25th in 1991-2000 and 27th in 2001-2014.
As of 2014, the city with the most disconnected street network in Jiangsu is Shaobo with an SNDi of 4.53, which is highly disconnected. Conversely, the most connected city is Haimen with an SNDi of -0.43, which is very well-connected. See trends for these cities: Haimen, Shaobo
The level of street-network sprawl in the aggregate network in Jiangsu peaked in 1976-1990. To get a sense of how the aggregate street network has changed in Jiangsu, we can consider three of its most populous cities: Suzhou, Nanjing and Changzhou. None of the most populous cities follow the same trend as the region. The level of street-network sprawl in the aggregate network in Suzhou followed a zig-zag trend with an overall increase. The level of street-network sprawl in the aggregate network in Nanjing rose steadily. The level of street-network sprawl in the aggregate network in Changzhou was at its lowest in 1991-2000.
To date, Jiangsu is the 23rd-most disconnected out of the 34 regions in China. Its position in the ranks since 1975 has risen; relative to other regions in China, the street network in Jiangsu has become more disconnected. Jiangsu ranked 28th in 1975, 24th in 1976-1990, 23rd in 1991-2000 and 23rd in 2001-2014.
