This paper contains a verbal description of the components of a computer model of the relationships between transport and the spatial distribution of population, housing, jobs, employment, shopping and land. Transport is measured in generalised cost units for the private and public transport modes. The demolition and building of housing are calculated within the model, taking into account any known information. Economic activity is divided into twelve sectors, which are allocated to three groups according to the degree of locational response to changes in transport costs. In the model a distinction is made between infrastructure, represented by houses and jobs, and the allocation of people to them. The allocation procedure ensures that those who have not moved retain the same residential or employment location over time. The distinction between infrastructure and activities means that inequalities in their provision, for example vacant houses and jobs, are included. Land availability is taken into account in the location of activities. The equation system of model is solved using an iterative technique. After convergence a wide range of information is obtained, including the spatial distribution of population, housing and jobs, accessibility indicators, modal splits and time and money expenditures on travel. The paper is concluded by a description of the integration of all these topics and the behaviour of the model over time. (Author/TRRL)
