Regina 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 Regina plotted against Saskatchewan and Canada. The SNDi of new construction in Regina peaked in 1991-2005, compared to Saskatchewan which rose steadily and Canada which peaked in 1976-1990. Most recently, Regina's incremental SNDi fell from 2.58 to 2.4 between 1991-2005 and 2006-2020. In terms of the aggregate network, Regina ranked 1st out of 2 cities in Saskatchewan and 4th out of 54 in Canada as of 2020.

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