Résumé
The study of reciprocal relations between urban forms and travel behaviours is a matter of great concern among researchers. In fact, relating travel behaviour models and land-use models into integrated models is one of the strategies deployed to better consider the complexity of urban behaviours.
We propose another perspective of this integration issue, a network-oriented definition of space, which embeds the structure of the transportation network in the modelling process. This is performed by conforming the classical measures of urban form, accessibility and density, to the actual space that supports the daily activities.
Subsequently, four conceptions of the urban space are proposed, from which are derived indexes describing the spatial structure of a particular area. Differences between classical measures (Euclidean distance and gross density) and network-oriented measures are discussed. These conceptions of space are finally appraised around a number of perspectives: examination of classical relations between density and mobility indicators with gross and network densities, estimation of average space occupancy per household (spatial obesity) and review of the dynamical aspect of population density. We believe that network-oriented perspectives have the potential to enhance the relevance of our modelling approaches. |
