Tepi 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 Tepi plotted against Southern Nations, Nationalities and Ethiopia. The SNDi of new construction in Tepi was at its lowest in 1976-1990, compared to Southern Nations, Nationalities which followed a zig-zag trend with an overall increase and Ethiopia which followed a zig-zag trend with an overall increase. Most recently, Tepi's incremental SNDi rose from 1.67 to 2.29 between 1991-2005 and 2006-2020. In terms of the aggregate network, Tepi ranked 6th out of 39 cities in Southern Nations, Nationalities and 27th out of 181 in Ethiopia as of 2020.

In new street additions, Tepi built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns, while Yiliang built increasingly disconnected streets from 1975 through 1976-1990, then improved and Companyganj built increasingly connected streets from 1975 through 1991-2005, then shifted to more disconnected patterns. For the full network, Tepi became progressively more disconnected, while Yiliang grew more disconnected from 1975 through 1976-1990, then improved and Companyganj became progressively more connected. Tepi and Yiliang have been converging in their street-network character since 1975.
