Taizhou: city in Zhejiang, 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 Taizhou as of 2014, the overall level of street-network sprawl is 1.44, which is relatively well-connected.
Trends in street network construction: The SNDis of street construction for the respective time periods are 1.09, 1.34, 3.26 and 2.63. Street construction in Taizhou increased in disconnectivity initially but has since improved. The streets constructed in 1991-2000 were the most disconnected.
Quantity of street network construction: The street network in Taizhou spans a total of 1205 kilometers. It is dominated by roads constructed in 1976-1990. These roads have an SNDi of 1.34, which is relatively well-connected.
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 1.09, 1.29, 1.43 and 1.44. Overall, the SNDi of the aggregate street network has risen: the street network in Taizhou has become more disconnected. This increase has slowed: between 1975 and 1976-1990, SNDi rose by 0.2 points, but between 1991-2000 and 2001-2014, it rose by just 0.01.
Taizhou and Zhejiang do not follow the same trend in the disconnectivity of their street network constructions. The SNDi in Taizhou peaked in 1991-2000, while the SNDi of street constructions in Zhejiang peaked in 1976-1990.
