Ibri 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 Ibri plotted against Al Dhahira and Oman. All three follow the same trend in new construction, suggesting a shared regional pattern of development. Most recently, Ibri's incremental SNDi fell from 4.18 to 3.22 between 1991-2005 and 2006-2020. In terms of the aggregate network, Ibri ranked 1st out of 1 cities in Al Dhahira and 7th out of 9 in Oman as of 2020.

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

In new street additions, Ibri built increasingly disconnected streets from 1975 through 1991-2005, then improved, while Rancho las Perris fluctuated in its street-construction patterns and Kabrai built increasingly connected streets from 1975 through 1991-2005, then shifted to more disconnected patterns. Looking at the full network, Rancho las Perris and Kabrai both became more connected from 1975 through 1991-2005, then grew more sprawly from 1991-2005 onwards, while Ibri grew more disconnected from 1975 through 1991-2005, then improved. Notably, Ibri had a more connected network than Kabrai in 1975 but the two have since reversed their relative ranking.
