Overview of Land Use Transport Models

The previous chapters in this Handbook have shown that spatial development, or land use, determines the need for spatial interaction, or transport, but that transport, by the accessibility it provides, also determines spatial development. However, it is difficult to empirically isolate impacts of land use on transport and vice versa because of the multitude of concurrent changes of other factors. This poses a problem if the likely impacts of integrated land-use and transport policies to reduce the demand for travel are to be predicted. There are principally three methods to predict those impacts. The first is to ask people how they would change their location and mobility behaviour if certain factors, such as land use regulations or transport costs, would change ('stated preference'). The second consists of drawing conclusions from observed decision behaviour of people under different conditions on how they would be likely to behave if these factors would change ('revealed preference'). The third method is to simulate human decision behaviour in mathematical models. All three methods have their advantages and disadvantages. Surveys can reveal also subjective factors of location and mobility decisions, however, their respondents can only make conjec-tures about how they would behave in still unknown situations, and the validity of such con

A Trinomial Logit Analysis of Household Composition

This article analyzes the effects on the marriage and household composition decisions of characteristics of the householder and of the place of residence. High housing costs reduced the probability of living alone. For female householders, increases in income decreased the probability of living alone rather than with unrelated individuals; the reverse was true for male householders. An increase in income decreased the probability of marriage for female householders over twenty-three years of age and increased the probability of marriage for male householders. Non-white householders over forty were less likely to be married than white householders over forty. Copyright American Real Estate and Urban Economics Association.
