The chart above shows the evolution of street network disconnectedness of the most connected and most disconnected cities in Iceland, for both new street additions (left) and the aggregate street network (right).
Iceland in context: Street-network sprawl of new development
The level of street-network sprawl in new development in Iceland peaked in 1976-1990. To get a sense of how street development has changed in Iceland, we can consider one of its most populous regions: Höfuðborgarsvæði. None of the most populous cities follow the same trend as the region. The level of street-network sprawl in new development in Höfuðborgarsvæði peaked in 1991-2005.
How do development practices in Iceland fare in comparison to others in the world? Most recently in 2006-2020, street construction in Iceland was the 5th-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 Iceland has become more disconnected. Iceland ranked 49th in 1975, 24th in 1976-1990, 30th in 1991-2005 and 5th in 2006-2020.
The largest city in Iceland is Reykjavik, with a population of 181800 people. Taking into account the entire (i.e. aggregate) street network in Reykjavik as of 2020, the overall level of street-network sprawl is 2.43, which is relatively well-connected. The level of street-network sprawl in new development in Reykjavik followed a zig-zag trend with an overall decrease.
Iceland in context: Aggregate street-network sprawl
As of 2020, the city with the most disconnected street network in Iceland is Reykjavik with an SNDi of 2.43, which is relatively well-connected. Conversely, the most connected city is Reykjavik with an SNDi of 2.43, which is relatively well-connected. See these two cities’ trends in the above graph, or dive deeper into each: Reykjavik, Reykjavik.
The level of street-network sprawl in the aggregate network in Iceland peaked in 1991-2005. To get a sense of how the aggregate street network has changed in Iceland, we can consider one of its most populous regions: Höfuðborgarsvæði. Disconnectivity in the most populous cities in Iceland follow the same country trend.
To date, Iceland is the 27th-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 Iceland has become more disconnected. Iceland ranked 49th in 1975, 35th in 1976-1990, 29th in 1991-2005 and 27th in 2006-2020.
