The influence of land use patterns on travel demand cannot be examined on an aggregate level, but only by analysing the travel behaviour of individuals. The analysis will be based on data for individual households obtained from the UK National Travel Survey (NTS). The NTS contains information on travel patterns (the number of trips, distance travelled and travel time by mode and journey purpose), vehicle ownership and a large range of socio-economic factors (income, household structure, employment, etc). Since accessibility and frequency measures are as reported by the respondents, it is likely that they contain errors, particularly for those who do not walk or take the bus to use the services. It is thus necessary to take such measurement errors into account in the model estimation. In the initial stage of the project, presented in this paper, models will be estimated for total mobility (the number of trips and the distance travelled) by all modes, as well as for commuting and non-commuting trips, separately. Further stages of this project will examine the implications of land-use patterns on mode choice. It is also intended to explore the possibility of combining the NTS data with additional land-use data using GIS. For the covering abstract see ITRD E126595.
