Mansa 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 Mansa plotted against Gujarat and India. The SNDi of new construction in Mansa was at its lowest in 1976-1990, compared to Gujarat which rose steadily and India which followed a zig-zag trend with an overall increase. Most recently, Mansa's incremental SNDi rose from 3.4 to 4.37 between 1991-2005 and 2006-2020. In terms of the aggregate network, Mansa ranked 51st out of 92 cities in Gujarat and 940th out of 1868 in India as of 2020.

Rankings go from most connected to most disconnected — rank 1 is the most connected.

In new street additions, Mansa built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns, while Lafayette built increasingly disconnected streets from 1975 through 1991-2005, then improved and Tangjiang built increasingly connected streets from 1975 through 1991-2005, then shifted to more disconnected patterns. For the full network, Mansa and Tangjiang both became more connected from 1975 through 1991-2005, then grew more sprawly from 1991-2005 onwards, while Lafayette became progressively more disconnected. Notably, Mansa had a more connected network than Tangjiang in 1975 but the two have since reversed their relative ranking.
