Mavelikkara 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 Mavelikkara plotted against Kerala and India. The SNDi of new construction in Mavelikkara was at its lowest in 1976-1990, compared to Kerala which was at its lowest in 1976-1990 and India which followed a zig-zag trend with an overall increase. Most recently, Mavelikkara's incremental SNDi rose from 4.5 to 4.7 between 1991-2005 and 2006-2020. In terms of the aggregate network, Mavelikkara ranked 9th out of 48 cities in Kerala and 1110th out of 1868 in India as of 2020.

For the full network, Mavelikkara became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards, while Juxian grew more disconnected from 1975 through 1991-2005, then improved and Freiburg im Breisgau became progressively more disconnected. Mavelikkara and Juxian have been converging in their street-network character since 1975.
