Baden-Württemberg: region in Germany
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 Baden-Württemberg as of 2014, the overall level of street-network sprawl is 2.31, which is in the 40th to 60th percentile of disconnectedness.
Trends in street network construction: The SNDis of street construction for the respective time periods are 1.87, 3.26, 3.42 and 3.29. Street construction in Baden-Württemberg increased in disconnectivity initially but has since improved. The streets constructed in 1991-2000 were the most disconnected.
Quantity of street network construction: The street network in Baden-Württemberg spans a total of 98217 kilometers. It is dominated by roads constructed prior to 1975. These roads have an SNDi of 1.87, which is relatively well-connected.
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 1.87, 2.2, 2.26 and 2.31. Overall, the SNDi of the aggregate street network has risen: the street network in Baden-Württemberg has become more disconnected. This increase has slowed: between 1975 and 1976-1990, SNDi rose by 0.33 points, but between 1991-2000 and 2001-2014, it rose by just 0.05.
The level of street-network sprawl in new development in Baden-Württemberg peaked in 1991-2000. To get a sense of how street development has changed in Baden-Württemberg, we can consider three of its most populous cities: Stuttgart, Mannheim and Karlsruhe. Out of the three cities, Mannheim and Karlsruhe do not follow the same trend as the region. The level of street-network sprawl in new development in Mannheim rose steadily. The level of street-network sprawl in new development in Karlsruhe rose steadily.
