In an effort to gauge the extent of road infrastructure challenges faced by some African nations, insights from an International Monetary Fund (IMF) working paper on road quality and mean speed score have emerged. The IMF devised a unique metric for assessing cross-country road quality, relying on the mean speed observed between major cities using data from Google Maps. This Mean Speed (MS) score serves as a pragmatic proxy for evaluating the overall quality and accessibility of roads.
The MS score exhibits a correlation with established metrics such as the World Bank's Rural Access Index and the World Economic Forum's (WEF) Quality of Road Infrastructure score. The following list unveils the ten African countries grappling with the most severe road infrastructure issues based on this comprehensive assessment.
Below are 10 African countries with the worst road infrastructure:
| Rank | Country | Mean score |
|---|---|---|
| 1 | Rwanda | 47 |
| 2 | Guinea | 50 |
| 3 | Burundi | 51 |
| 4 | Madagascar | 51 |
| 5 | Gambia | 53 |
| 6 | Nigeria | 55 |
| 7 | Ghana | 56 |
| 8 | Cameroon | 56 |
| 9 | Tanzania | 57 |
| 10 | Kenya | 57 |
