ABSTRACT
There is a close relationship between urban structure and forms of transport. Transport opportunities and travel constraints give shape to the city, while the structure of the city affects the form and character of transport. There is a reciprocal relationship. This is not to say that transport causes changes in urban form. It is too facile to say that transport improvements, for example, cause urban expansion. They are a necessary precondition but not necessarily a cause. People are always on the move. The prime reason for population movement in cities is the separation of activity centres. Within the home, for example, people move from bedroom to bathroom to kitchen in order to do different tasks, fulfil different functions and do different things. The journey to work is based on the separation between home and workplace. This separation has increased as a function of suburbanisation, aided by land-use zoning which separates residential areas from industrial and commercial centres.
