Alibag 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 Alibag plotted against Maharashtra and India. The SNDi of new construction in Alibag was at its lowest in 1976-1990, compared to Maharashtra which followed a zig-zag trend with an overall increase and India which followed a zig-zag trend with an overall increase. Most recently, Alibag's incremental SNDi rose from 5.22 to 6.54 between 1991-2005 and 2006-2020. In terms of the aggregate network, Alibag ranked 152nd out of 157 cities in Maharashtra and 1628th out of 1868 in India as of 2020.

In new street additions, Alibag built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns, while Lincoln built increasingly disconnected streets from 1975 through 1991-2005, then improved and Punalur built increasingly disconnected streets over time. Looking at the full network, Lincoln and Punalur both became progressively more disconnected, while Alibag became more connected from 1975 through 1991-2005, then grew more sprawly from 1991-2005 onwards. Alibag and Lincoln have been converging in their street-network character since 1975.
