Eritrea in context: Street-network sprawl of new development

The level of street-network sprawl in new development in Eritrea followed a zig-zag trend with an overall increase. To get a sense of how street development has changed in Eritrea, we can consider three of its most populous regions: Semenawi Keyih Bahri, Maekel and Anseba. None of the most populous cities follow the same trend as the region. The level of street-network sprawl in new development in Semenawi Keyih Bahri was at its lowest in 1991-2005. The level of street-network sprawl in new development in Maekel rose steadily. The level of street-network sprawl in new development in Anseba rose steadily.

The largest city in Eritrea is Asmara, with a population of 369900 people. Taking into account the entire (i.e. aggregate) street network in Asmara as of 2020, the overall level of street-network sprawl is 1.68, which is very well-connected. The level of street-network sprawl in new development in Asmara peaked in 1991-2005.

Eritrea in context: Aggregate street-network sprawl

As of 2020, the city with the most disconnected street network in Eritrea is Barentu with an SNDi of 3.47, which is relatively sprawly. Conversely, the most connected city is Teseney with an SNDi of 1.03, which is very well-connected. See these two cities’ trends in the above graph, or dive deeper into each: Teseney, Barentu.

The level of street-network sprawl in the aggregate network in Eritrea rose steadily. To get a sense of how the aggregate street network has changed in Eritrea, we can consider three of its most populous regions: Semenawi Keyih Bahri, Maekel and Anseba. Out of the three regions, Semenawi Keyih Bahri does not follow the same trend as the country. The level of street-network sprawl in the aggregate network in Semenawi Keyih Bahri was at its lowest in 1991-2005.

The largest city in Eritrea is Asmara, with a population of 369900 people. Taking into account the entire (i.e. aggregate) street network in Asmara as of 2020, the overall level of street-network sprawl is 1.68, which is very well-connected. The level of street-network sprawl in the aggregate network in Asmara rose steadily.
