Kohat in context: Street-network sprawl trends

The chart above shows SNDi trends for new street additions (left panel) and the entire network (right panel), with Kohat plotted against Khyber-Pakhtunkhwa and Pakistan. The SNDi of new construction in Kohat was at its lowest in 1991-2005, compared to Khyber-Pakhtunkhwa which followed a zig-zag trend with an overall increase and Pakistan which followed a zig-zag trend with an overall increase. Most recently, Kohat's incremental SNDi rose from 3.89 to 4.36 between 1991-2005 and 2006-2020. In terms of the aggregate network, Kohat ranked 21st out of 67 cities in Khyber-Pakhtunkhwa and 204th out of 292 in Pakistan as of 2020.

• Manado, Indonesia
• Port Sudan, Sudan
• Waidhan, India

In new street additions, Kemerovo and Manado both built increasingly disconnected streets over time, while Kohat built increasingly connected streets from 1975 through 1991-2005, then shifted to more disconnected patterns. Looking at the full network, Kemerovo and Manado both became progressively more disconnected, while Kohat became progressively more connected. Notably, Kohat had a more sprawly network than Manado in 1975, but the two have since reversed their relative ranking.
