Glasgow in context
The chart above shows SNDi trends for new street additions (left panel) and the entire network (right panel), with Glasgow plotted against Scotland and United Kingdom. All three follow the same trend in new construction, suggesting a shared regional pattern of development. Most recently, Glasgow's incremental SNDi fell from 4.8 to 4.43 between 1991-2005 and 2006-2020. In terms of the aggregate network, Glasgow ranked 7th out of 11 cities in Scotland and 59th out of 143 in United Kingdom as of 2020.

In new street additions, Glasgow built increasingly disconnected streets from 1975 through 1991-2005, then improved, while Samarinda built increasingly disconnected streets over time and Shahajadpur fluctuated in its street-construction patterns. For the full network, Glasgow and Samarinda both became progressively more disconnected, while Shahajadpur fluctuated in connectivity. Glasgow and Samarinda have been growing further apart in their street-network character since 1975.
