demand for transport in cities whether of people or goods, is determined largely by the spatial arrangement of different land uses. In Third world cities, rapid urban expansion driven by in-migration leads to many new arrivals being forced to live at increasing distances from the job opportunities of the central city. the significance of informal economic activities also produces a pattern of travel demand with spatial and temporal characteristics different from those generated by the more formally organised economic activity of the Western city. The polarised distribution of income within the Third world city also affects levels of mobility and patterns of travel. The diverse demand for urban transport cannot be satisfies by the kind of high-capacity radial transport corridors that serve Western cities.
