A spatial analysis of motorcycle taxis activities for environmental planning – the case of Port-au-Prince, Haiti

We report a novel method for the spatial analysis of informal transport activities for future environmental planning. It uses a combination of spatial data gathered with GPS devices and semi-formal interviews. We show that the current configuration of the system is not optimized. It leads to a greater concentration of motorcycle taxis activities in denser urban areas, emitting high levels of noise and air pollution. Recommendations include decentralizing part of the activity and closer monitoring of the number of pilots
