Cities are centres in which a variety of functions and activities are organised in a relatively compact space. People engage in these activities through spatial interaction. The way in which these activities are arranged spatially has a huge bearing on the amount of spatial interaction (and thus travel demand) generated and the infrastructure required to facilitate this interaction. The physical manifestation of this spatial arrangement is referred to as urban form, a concept which can help us understand the way cities function in terms of their spatial structure and pattern, at different scales. The processes of land use and infrastructure development that determine urban form are closely linked and are mutually influencing. In this course, we investigate urban form and are addressing urban spatial development concepts in terms of their spatial interaction. We look at the most important theoretical concepts that describe the relation between land use and transportation. We make use of a variety of modelling tools and techniques to help analyse and understand this mutual relation and come up with better spatial planning policies.
