Bazoul 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 Bazoul plotted against Jijel and Algeria. The SNDi of new construction in Bazoul was at its lowest in 1976-1990, compared to Jijel which peaked in 1976-1990 and Algeria which followed a zig-zag trend with an overall decrease. Most recently, Bazoul's incremental SNDi rose from 3.97 to 4.73 between 1991-2005 and 2006-2020. In terms of the aggregate network, Bazoul ranked 3rd out of 4 cities in Jijel and 91st out of 109 in Algeria as of 2020.

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

In new street additions, Bazoul built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns, while Parbatipur built increasingly disconnected streets over time and Chibia fluctuated in its street-construction patterns. For the full network, Bazoul became more connected from 1975 through 1991-2005, then grew more sprawly from 1991-2005 onwards, while Parbatipur became progressively more disconnected and Chibia became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards. Bazoul and Parbatipur have been converging in their street-network character since 1975.
