The widely recognised but not well understood interaction between land use and transport (LU&T) is the subject of this chapter. A theoretical framework and the associated modelling approach is presented in this chapter as a way of understanding the interaction between land use and transport. The basic behavioural position defining this interaction is centred on the activities that individuals wish to participate in. Since most activities are spatially dispersed in a way described by the land-use pattern, to reach them individuals travel. The resulting interaction takes place in two ways. First, the location pattern of activities induces a trip pattern, as the required cost of performing activities; and, second, that location of each activity is dependent on the transport system, as it defines the travel cost associated with all activities performed in the future. This approach recognises that the LU&T interaction is the result of individual behaviour, that the land use describes the pattern of opportunities to perform activities, and that transport needs are induced by the need to perform activities. With this in mind, the key questions are how households decide where to locate their residence and firms their economic activities - because it imposes conditions on trip-making decisions - and how they decide what activities to perform and where they are located. The authors concentrate here on understanding how activities locate in the urban area and the interaction between land use and transport.
