The accessibility in Land-Use Transport Interaction models : four essays on location choice models

Abstract : This PhD thesis has as objective to examine the place and the importance of accessibility in location choice models of households and firms, two key construction elements of Land-Use Transport Interaction models. More specifically, the aim is to analyse the effect of various methodological choices from a theoretical and empirical point of view in order to give some answers to theoretical, methodological, empirical and policy issues. Having as a case study the urban area of Lyon and using discrete models to explain the location choices of households and firms, four research papers comprise the main work of this dissertation.In the first paper, the objective was to analyse the effect of the accessibility measure on the results of residential location choice model. While accessibility has always been important at theoretical level, at empirical level, some works questioned its importance, considering other location characteristics as more influential. This paper examines whether different accessibility measurement methods can lead to divergent results. The conclusion is that accessibility is an indispensable variable for residential location choice models and the conclusion remains the same whatever is the measure. Without accessibility, the model gives inconsistent results. Complex accessibility measures give better results, especially for predictions, but simple measures are also relevant for residential location choices modelling.In the second paper, the objective was to analyse the differences of accessibility preferences between new and relocating firms. Accessibility is one of the most important attributes of a location choice of an economic establishment. However, even if it seems intuitive, works analysing any differences between creations and relocations are scarce. Using data from eighteconomic sectors and comparing creations to relocations, the results demonstrate that the effect of accessibility differs between in the same economic sector.In the third paper, the objective was to evaluate the difference of the accessibility impact on the location choices of firms of the business services sector. Distinguishing between Front Office and Back Office business services in a location choice model, the results demonstrate that the effect of accessibility differs between economic subsectors.In the fourth paper, the objective was to analyse the temporal evolution of the preferences for accessibility for residential choices. More and more people choose to buy a residence at the suburbs taking advantage of the accessibility increase. At the same time, young households, the so called millennials, choose to rent in central areas. Distinguishing between renters andowners, the analysis of the elasticities for 1999, 2006 and 2013 confirm the initial intuition. Renters were always more sensitive to accessibility to employment. More importantly, renters show an increasing preference for accessibility during the analysis period, while the owners the opposite. We suggest that planners and model developers should integrate temporal dynamics into their models in order to anticipate better future tendencies.
