F.C.T.: region in Pakistan
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 F.C.T. as of 2014, the overall level of street-network sprawl is 4.26, which is highly disconnected.
Trends in street network construction: The SNDis of street construction for the respective time periods are 3.79, 3.34, 3.9 and 4.78. The disconnectivity of new streets constructed in F.C.T. fell, then rose. In 1976-1990, new street layouts were the most connected.
Quantity of street network construction: The street network in F.C.T. spans a total of 3300 kilometers. It is dominated by roads constructed in 2001-2014. These roads have an SNDi of 4.78, which is highly disconnected.
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 3.79, 3.42, 3.73 and 4.26. The SNDi of the aggregate street network in fell at first, but F.C.T. has worsened in disconnectivity since 1990.
The level of street-network sprawl in new development in F.C.T. was at its lowest in 1976-1990. To get a sense of how street development has changed in F.C.T., we can consider two of its most populous cities: Rawalpindi [Islamabad] and Bani Gala. Out of the two cities, Bani Gala does not follow the same trend as the region. The level of street-network sprawl in new development in Bani Gala followed a zig-zag trend with an overall decrease.
How do development practices in F.C.T. fare in comparison to others in Pakistan? Most recently in 2001-2014, street construction in F.C.T. was the 5th-most disconnected out of the 8 regions in Pakistan. Its position in the ranks since 1975 has not changed. F.C.T. ranked 5th in 1975, 6th in 1976-1990, 7th in 1991-2000 and 5th in 2001-2014.
As of 2014, the city with the most disconnected street network in F.C.T. is Bani Gala with an SNDi of 6.15, which is highly disconnected. Conversely, the most connected city is Rawalpindi [Islamabad] with an SNDi of 4.18, which is highly disconnected. See trends for these cities: Rawalpindi [Islamabad], Bani Gala
