The chart above shows the evolution of street network disconnectedness of the most connected and most disconnected cities in Vietnam, for both new street additions (left) and the aggregate street network (right).
Vietnam in context: Street-network sprawl of new development
The level of street-network sprawl in new development in Vietnam rose steadily. To get a sense of how street development has changed in Vietnam, we can consider three of its most populous regions: Hồ Chí Minh, Hà Nội and An Giang. Out of the three regions, Hà Nội and An Giang do not follow the same trend as the country. The level of street-network sprawl in new development in Hà Nội peaked in 1991-2005. The level of street-network sprawl in new development in An Giang peaked in 1991-2005.
How do development practices in Vietnam fare in comparison to others in the world? Most recently in 2006-2020, street construction in Vietnam was the 146th-most disconnected out of the 179 countries in the world. Its position in the ranks since 1975 has risen; relative to other countries in the world, street construction in Vietnam has become more disconnected. Vietnam ranked 163rd in 1975, 146th in 1976-1990, 143rd in 1991-2005 and 146th in 2006-2020.
The largest city in Vietnam is Ho Chi Minh City, with a population of 11251200 people. Taking into account the entire (i.e. aggregate) street network in Ho Chi Minh City as of 2020, the overall level of street-network sprawl is 4.87, which is sprawly. The level of street-network sprawl in new development in Ho Chi Minh City rose steadily.
Vietnam in context: Aggregate street-network sprawl
As of 2020, the city with the most disconnected street network in Vietnam is Tân Châu with an SNDi of 8.55, which is very sprawly. Conversely, the most connected city is Quảng Phú with an SNDi of 2.41, which is well-connected. See these two cities’ trends in the above graph, or dive deeper into each: Quảng Phú, Tân Châu.
The level of street-network sprawl in the aggregate network in Vietnam rose steadily. To get a sense of how the aggregate street network has changed in Vietnam, we can consider three of its most populous regions: Hồ Chí Minh, Hà Nội and An Giang. Disconnectivity in the most populous cities in Vietnam follow the same country trend.
To date, Vietnam is the 152nd-most disconnected out of the 179 countries in the world. Its position in the ranks since 1975 has risen; relative to other countries in the world, the street network in Vietnam has become more disconnected. Vietnam ranked 163rd in 1975, 160th in 1976-1990, 155th in 1991-2005 and 152nd in 2006-2020.
