The link between urban development and the modal split in commuting: The case of Biscay

This paper presents an empirical analysis of the links between different land use patterns and the modal split in commuting. The analysis is conducted at municipal level, based on data on land use and mobility characteristics of the de-urbanisation process in Biscay, a small European province, from 1991 to 2001. The links are assessed by means of multiple regression analysis, in which specific techniques of spatial econometrics are applied in order to avoid biased results and unreliable inferences due to spatial dependence. The findings reveal, at municipal level, the importance of gross population density, geographic concentration of the population and, to a lesser extent, the ratio of jobs to residents in explaining the modal split in commuting, and the influence of access to public transport. It is also shown that public transport services have spillover effects that extend beyond the limits of the municipality and encourage use in adjacent areas. © 2014 Elsevier Ltd.
