Siem Reap 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 Siem Reap plotted against Siemréab and Cambodia. The SNDi of new construction in Siem Reap was at its lowest in 1991-2005, compared to Siemréab which was at its lowest in 1991-2005 and Cambodia which rose steadily. Most recently, Siem Reap's incremental SNDi rose from 3.29 to 3.91 between 1991-2005 and 2006-2020.

For the full network, Siem Reap became more connected from 1975 through 1991-2005, then grew more sprawly from 1991-2005 onwards, while Derby became progressively more disconnected and Dordrecht became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards. Siem Reap and Derby have been converging in their street-network character since 1975.
