Jizhou: city in Tianjin, 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 Jizhou as of 2014, the overall level of street-network sprawl is 0.1, which is very well-connected.
Trends in street network construction: The SNDis of street construction for the respective time periods are -0.67, 1.01, 0.44 and -0.08. Street construction in Jizhou increased in disconnectivity initially but has since improved. The streets constructed in 1976-1990 were the most disconnected.
Quantity of street network construction: The street network in Jizhou spans a total of 168 kilometers. It is dominated by roads constructed prior to 1975. These roads have an SNDi of -0.67, which is very 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 -0.67, 0.14, 0.11 and 0.1. The aggregate street network in Jizhou increased in disconnectivity initially,but the trend has turned around after 1990.
