Rural areas in Africa are largely characterized by poor road networks. This poor state of rural roads contributes to the vulnerability of communities in developing countries by hampering access to vital social services and opportunities. In addition, maps of the road networks are largely incomplete and not up-to-date. In this paper, motorcycle taxis, which are a dominant mode of transport in rural areas in Africa, were tracked using affordable GPS data loggers. The resulting GPS trajectories revealed the village-level road networks that are used by rural residents. The results showed that GPS trajectories from motorcycle taxis can improve the map coverage of rural road networks and boost other mapping initiatives like OpenStreetMap (OSM). Specifically, GPS-derived data can improve the coverage of official road maps in rural areas by up to 70% and OSM data by up to 60%. View the paper here.
