The chart above shows the evolution of street network disconnectedness of the most connected and most disconnected cities in Germany, for both new street additions (left) and the aggregate street network (right).
Germany in context: Street-network sprawl of new development
The level of street-network sprawl in new development in Germany rose steadily. To get a sense of how street development has changed in Germany, we can consider three of its most populous regions: Nordrhein-Westfalen, Bayern and Berlin. Out of the three regions, Bayern does not follow the same trend as the country. The level of street-network sprawl in new development in Bayern peaked in 1991-2005.
How do development practices in Germany fare in comparison to others in the world? Most recently in 2006-2020, street construction in Germany was the 45th-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 Germany has become more connected. Germany ranked 35th in 1975, 51st in 1976-1990, 53rd in 1991-2005 and 45th in 2006-2020.
The largest city in Germany is Berlin, with a population of 3359300 people. Taking into account the entire (i.e. aggregate) street network in Berlin as of 2020, the overall level of street-network sprawl is 1.58, which is very well-connected. The level of street-network sprawl in new development in Berlin rose steadily.
Germany in context: Aggregate street-network sprawl
As of 2020, the city with the most disconnected street network in Germany is Ritterhude with an SNDi of 4.9, which is very sprawly. Conversely, the most connected city is Darmstadt with an SNDi of 1.17, which is very well-connected. See these two cities’ trends in the above graph, or dive deeper into each: Darmstadt, Ritterhude.
The level of street-network sprawl in the aggregate network in Germany rose steadily. To get a sense of how the aggregate street network has changed in Germany, we can consider three of its most populous regions: Nordrhein-Westfalen, Bayern and Berlin. Disconnectivity in the most populous cities in Germany follow the same country trend.
To date, Germany is the 32nd-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 Germany has become more disconnected. Germany ranked 35th in 1975, 31st in 1976-1990, 34th in 1991-2005 and 32nd in 2006-2020.
The largest city in Germany is Berlin, with a population of 3359300 people. Taking into account the entire (i.e. aggregate) street network in Berlin as of 2020, the overall level of street-network sprawl is 1.58, which is very well-connected. The level of street-network sprawl in the aggregate network in Berlin rose steadily.
