Aceh: region in Indonesia
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 Aceh as of 2014, the overall level of street-network sprawl is 6.73, which is highly disconnected.
Trends in street network construction: The SNDis of street construction for the respective time periods are 6.69, 4.21, 7.95 and 7.77. Disconnectivity in street construction in Aceh follows a zig-zag trend. In 1976-1990, street construction was most disconnected, while construction was most connected in 1991-2000.
Quantity of street network construction: The street network in Aceh spans a total of 41920 kilometers. It is dominated by roads constructed prior to 1975. These roads have an SNDi of 6.69, 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 6.69, 6.37, 6.51 and 6.73. The SNDi of the aggregate street network in fell at first, but Aceh has worsened in disconnectivity since 1990.
The level of street-network sprawl in new development in Aceh followed a zig-zag trend with an overall increase. To get a sense of how street development has changed in Aceh, we can consider three of its most populous cities: Banda Aceh, Langsa and Bireuen. None of the most populous cities follow the same trend as the region. The level of street-network sprawl in new development in Banda Aceh followed a zig-zag trend with an overall increase. The level of street-network sprawl in new development in Langsa followed a zig-zag trend with an overall increase. The level of street-network sprawl in new development in Bireuen followed a zig-zag trend.

The level of street-network sprawl in the aggregate network in Aceh was at its lowest in 1976-1990. To get a sense of how the aggregate street network has changed in Aceh, we can consider three of its most populous cities: Banda Aceh, Langsa and Bireuen. None of the most populous cities follow the same trend as the region. The level of street-network sprawl in the aggregate network in Banda Aceh rose steadily. The level of street-network sprawl in the aggregate network in Langsa rose steadily. The level of street-network sprawl in the aggregate network in Bireuen rose steadily.
To date, Aceh is the 7th-most disconnected out of the 32 regions in Indonesia. Its position in the ranks since 1975 has fallen; relative to other regions in Indonesia, the street network in Aceh has become more connected.
