Uttarakhand: region in India
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 Uttarakhand as of 2014, the overall level of street-network sprawl is 6.22, which is highly disconnected.
Trends in street network construction: The SNDis of street construction for the respective time periods are 5.7, 6.21, 6.75 and 6.38. Street construction in Uttarakhand 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 Uttarakhand spans a total of 16956 kilometers. It is dominated by roads constructed in 2001-2014. These roads have an SNDi of 6.38, which is highly disconnected.
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 5.7, 5.88, 6.17 and 6.22. Overall, the SNDi of the aggregate street network has risen: the street network in Uttarakhand has become more disconnected. This increase has slowed: between 1975 and 1976-1990, SNDi rose by 0.18 points, but between 1991-2000 and 2001-2014, it rose by just 0.05.
The level of street-network sprawl in new development in Uttarakhand peaked in 1991-2000. To get a sense of how street development has changed in Uttarakhand, we can consider three of its most populous cities: Dehradun, Haridwar and Haldwani. Out of the three cities, Haridwar and Haldwani do not follow the same trend as the region. The level of street-network sprawl in new development in Haridwar followed a zig-zag trend with an overall increase. The level of street-network sprawl in new development in Haldwani followed a zig-zag trend with an overall increase.
How do development practices in Uttarakhand fare in comparison to others in India? Most recently in 2001-2014, street construction in Uttarakhand was the 7th-most disconnected out of the 35 regions in India. Its position in the ranks since 1975 has fallen; relative to other regions in India, street construction in Uttarakhand has become more connected. Uttarakhand ranked 5th in 1975, 4th in 1976-1990, 4th in 1991-2000 and 7th in 2001-2014.
As of 2014, the city with the most disconnected street network in Uttarakhand is Dehradun with an SNDi of 6.27, which is highly disconnected. Conversely, the most connected city is Lālkua with an SNDi of -0.11, which is very well-connected. See trends for these cities: Lālkua, Dehradun
The level of street-network sprawl in the aggregate network in Uttarakhand rose steadily. To get a sense of how the aggregate street network has changed in Uttarakhand, we can consider three of its most populous cities: Dehradun, Haridwar and Haldwani. None of the most populous cities follow the same trend as the region. The level of street-network sprawl in the aggregate network in Dehradun peaked in 1991-2000. The level of street-network sprawl in the aggregate network in Haridwar was at its lowest in 1976-1990. The level of street-network sprawl in the aggregate network in Haldwani was at its lowest in 1991-2000.
To date, Uttarakhand is the 6th-most disconnected out of the 35 regions in India. Its position in the ranks since 1975 has fallen; relative to other regions in India, the street network in Uttarakhand has become more connected. Uttarakhand ranked 5th in 1975, 5th in 1976-1990, 4th in 1991-2000 and 6th in 2001-2014.
