Tuni 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 Tuni plotted against Andhra Pradesh and India. The SNDi of new construction in Tuni rose steadily, compared to Andhra Pradesh which followed a zig-zag trend with an overall increase and India which followed a zig-zag trend with an overall increase. Most recently, Tuni's incremental SNDi rose from 3.83 to 4.05 between 1991-2005 and 2006-2020. In terms of the aggregate network, Tuni ranked 65th out of 91 cities in Andhra Pradesh and 882nd out of 1868 in India as of 2020.

What about similarly populated cities?

• Tomakomai, Japan
• Tirwaganj, India
• Bolpur, India
• Hamilton, New Zealand
• Burgos, Spain
• Anand Nagar, India

In new street additions, Tuni built increasingly disconnected streets over time, while Tomakomai fluctuated in its street-construction patterns and Hamilton built increasingly disconnected streets from 1975 through 1991-2005, then improved. For the full street network, though, all three cities follow the same trend. Tuni and Tomakomai have been growing further apart in their street-network character since 1975.
