Geo gecko used this map to create a tube map for easier understanding of the trans-African highway system. The schematic transit map is often used to bring clarity to a complex system.
However, clarity comes at the expense of geographic accuracy and distances. So please don't use it for navigating the short drive from Cairo to cape town.
The importance of transport infrastructure to economic development is obvious, especially in Africa. The large number of landlocked countries, the developing regional integration and the massive new projects, such as lappset, make for very interesting times indeed in African transport infrastructure.
