1. Objectifs

Intentions :
« This paper is an attempt to bridge the gap between, on the one hand, the mobility behaviour of households and their perception of accessibility to urban amenities and, on the other hand, house price dynamics as captured through hedonic modelling. It focuses on analyzing mobility behaviour of people and estimating their sensitivity to travel time from home to service places so as to assess their action-based, demand-driven, accessibility. » (p. 1)

Questions/Hypothèses :
« [T]hree research hypotheses are to be tested [...]:
- Hypothesis H1: Centrality and accessibility addressing two different realities, both should emerge as statistically significant where used concurrently.
- Hypothesis H2: The willingness to pay for additional accessibility, as measured through house purchase prices, is not homogeneous over space and varies with both trip purpose and type of household.
- Hypothesis H3: Because of their specificity with respect to individual and household needs and preferences, demand-driven accessibility indices perform better than supply-driven indices in explaining house price differences. » (pp. 12-13)

2. Méthode

Échantillon/Matériau :
« 952 single-family houses sold between 1993 and 1996. » (p. 1) « Research hypotheses are to be empirically tested using [this] 952-unit, spatially stratified and randomly selected, sub-sample on which a phone survey was conducted in order to get information about the buyer’s profile (household structure, age, income, choice factors, etc.). » (p. 13)

Type de traitement des données :
Analyse statistique

3. Résumé

« Findings indicate that, while overall accessibility to jobs and services is quite homogeneous throughout the agglomeration thanks to a highly efficient highway network, there are nevertheless statistically significant differences in the way accessibility is structured depending on trip purposes and household profiles. This supports the hypothesis that various groups of people have a heterogeneous perception of space, thereby adjusting their willingness to pay for more centrality/accessibility when choosing their home, depending on their needs and preferences. » (p. 1)
