The chart above shows the evolution of street network disconnectedness of the most connected and most disconnected cities in Indonesia, for both new street additions (left) and the aggregate street network (right).
Indonesia in context: Street-network sprawl of new development
The level of street-network sprawl in new development in Indonesia rose steadily. To get a sense of how street development has changed in Indonesia, we can consider three of its most populous regions: Jawa Barat, Jawa Timur and Jawa Tengah. Out of the three regions, Jawa Barat does not follow the same trend as the country. The level of street-network sprawl in new development in Jawa Barat followed a zig-zag trend with an overall increase.
How do development practices in Indonesia fare in comparison to others in the world? Most recently in 2006-2020, street construction in Indonesia was the 149th-most disconnected out of the 179 countries in the world. Its position in the ranks since 1975 has fallen; relative to other countries in the world, street construction in Indonesia has become more connected. Indonesia ranked 147th in 1975, 149th in 1976-1990, 145th in 1991-2005 and 149th in 2006-2020.
The largest city in Indonesia is Jakarta, with a population of 35485200 people. Taking into account the entire (i.e. aggregate) street network in Jakarta as of 2020, the overall level of street-network sprawl is 4.73, which is sprawly. The level of street-network sprawl in new development in Jakarta followed a zig-zag trend with an overall increase.
Indonesia in context: Aggregate street-network sprawl
As of 2020, the city with the most disconnected street network in Indonesia is Karyamakmur with an SNDi of 7.31, which is very sprawly. Conversely, the most connected city is Agats with an SNDi of 1.75, which is very well-connected. See these two cities’ trends in the above graph, or dive deeper into each: Agats, Karyamakmur.
The level of street-network sprawl in the aggregate network in Indonesia rose steadily. To get a sense of how the aggregate street network has changed in Indonesia, we can consider three of its most populous regions: Jawa Barat, Jawa Timur and Jawa Tengah. Disconnectivity in the most populous cities in Indonesia follow the same country trend.
