Alanya 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 Alanya plotted against Antalya and Turkey. The SNDi of new construction in Alanya was at its lowest in 1976-1990, compared to Antalya which followed a zig-zag trend with an overall increase and Turkey which followed a zig-zag trend with an overall increase. Most recently, Alanya's incremental SNDi rose from 1.71 to 2.48 between 1991-2005 and 2006-2020. In terms of the aggregate network, Alanya ranked 1st out of 5 cities in Antalya and 51st out of 174 in Turkey as of 2020.

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

In new street additions, Alanya built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns, while Chagni built increasingly disconnected streets over time and Heuleut built increasingly disconnected streets from 1975 through 1991-2005, then improved. Looking at the full network, Chagni and Heuleut both became progressively more disconnected, while Alanya became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards. Notably, Alanya had a more sprawly network than Chagni in 1975 but the two have since reversed their relative ranking.
