Taiwan in context: Street-network sprawl of new development

The level of street-network sprawl in new development in Taiwan followed a zig-zag trend with an overall increase. To get a sense of how street development has changed in Taiwan, we can consider three of its most populous regions: Taiwan, Taichung and Kaohsiung. Out of the three regions, Taiwan does not follow the same trend as the country. The level of street-network sprawl in new development in Taiwan rose steadily.

How do development practices in Taiwan fare in comparison to others in the world? Most recently in 2006-2020, street construction in Taiwan was the 34th-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 Taiwan has become more connected. Taiwan ranked 13th in 1975, 22nd in 1976-1990, 25th in 1991-2005 and 34th in 2006-2020.

Taking into account the entire (i.e. aggregate) street network in Taipei as of 2020, the overall level of street-network sprawl is 2.38, which is well-connected. The level of street-network sprawl in new development in Taipei rose steadily.

Taiwan in context: Aggregate street-network sprawl

As of 2020, the city with the most disconnected street network in Taiwan is Pingtung City with an SNDi of 2.66, which is relatively well-connected. Conversely, the most connected city is Tainan with an SNDi of 1.36, which is very well-connected. See these two cities’ trends in the above graph, or dive deeper into each: Tainan, Pingtung City.

The level of street-network sprawl in the aggregate network in Taiwan rose steadily. To get a sense of how the aggregate street network has changed in Taiwan, we can consider three of its most populous regions: Taiwan, Taichung and Kaohsiung. Disconnectivity in the most populous cities in Taiwan follow the same country trend.
