Developing country kerbsides are often characterised by uncovered gutters. Gutters meant to carry excess rain water away are often used as an extension of the sewage system. Transport planning for developing countries often is undertaken by transport planners who are either from countries with developed infrastructure or have been trained into the transport paradigm associated with developed infrastructure. In this context, the issue of physical and social friction at the intersection of kerb, gutter and highway has been badly neglected.

The following galleries show situations of physical and social friction along highways in Ghana. Situations of social and physical friction include washing being hung on safety barriers in the Nima Highway community, road side and centre road trading by child hawkers, uncovered gutters over which pedestrians are pushed by heavy traffic, mixed traffic which includes motorised and non motorised forms and the roadway being used as a vehicle repair location.
