Singapore
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 Singapore as of 2014, the overall level of street-network sprawl is 4.96, which is highly disconnected.
Trends in street network construction: The SNDis of street construction for the respective time periods are 4.48, 5.79, 5.45 and 6.0. Disconnectivity in street construction in Singapore follows a zig-zag trend. In 1975, street construction was most disconnected, while construction was most connected in 2001-2014.
Quantity of street network construction: The street network in Singapore spans a total of 125546 kilometers. It is dominated by roads constructed prior to 1975. These roads have an SNDi of 4.48, 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 4.48, 4.73, 4.83 and 4.96. Overall, the SNDi of the aggregate street network has risen: the street network in Singapore has become more disconnected. This increase has slowed: between 1975 and 1976-1990, SNDi rose by 0.25 points, but between 1991-2000 and 2001-2014, it rose by just 0.14.
The level of street-network sprawl in new development in Singapore followed a zig-zag trend with an overall increase. To get a sense of how street development has changed in Singapore, we can consider one of its most populous regions: Johor. None of the most populous cities follow the same trend as the region. The level of street-network sprawl in new development in Johor followed a zig-zag trend with an overall increase.
How do development practices in Singapore fare in comparison to others in the world? Most recently in 2001-2014, street construction in Singapore was the 33rd-most disconnected out of the 155 countries in the world. Its position in the ranks since 1975 has fallen; relative to other countries in the world, street construction in Singapore has become more connected. Singapore ranked 23rd in 1975, 11th in 1976-1990, 40th in 1991-2000 and 33rd in 2001-2014.
The largest city in Singapore is Singapore, with a population of 6920900 people. Taking into account the entire (i.e. aggregate) street network in Singapore as of 2014, the overall level of street-network sprawl is 3.4, which is highly disconnected. The level of street-network sprawl in new development in Singapore followed a zig-zag trend with an overall increase.
As of 2014, the city with the most disconnected street network in Singapore is Singapore with an SNDi of 3.4, which is highly disconnected. Conversely, the most connected city is Singapore with an SNDi of 3.4, which is highly disconnected. See trends for these cities: Singapore, Singapore
The level of street-network sprawl in the aggregate network in Singapore rose steadily. To get a sense of how the aggregate street network has changed in Singapore, we can consider one of its most populous regions: Johor. None of the most populous cities follow the same trend as the region. The level of street-network sprawl in the aggregate network in Johor rose steadily.
To date, Singapore is the 27th-most disconnected out of the 155 countries in the world. Its position in the ranks since 1975 has fallen; relative to other countries in the world, the street network in Singapore has become more connected. Singapore ranked 23rd in 1975, 26th in 1976-1990, 30th in 1991-2000 and 27th in 2001-2014.
