Trailer use may be most pragmatically applied in secondary urban areas and the urban periphery where access to transportation is more constrained than in capitol cities such as Accra or Lomé. The development of prototype bicycle trailers has a history of mixed success in Ghana, but the extent to which trailers are being used in Togo is unclear.
