A New Anthropocentric Approach in Accessibility Analysis: The Activity Space and the Accessibility Measures

This study aims to examine individual accessibility experiences in space and time, through developing a new composite accessibility measure using spatial, temporal and travel data. According to time-geography, all the activities have spatial extent and temporal dimensions and they are unseparated. So, the proposed measure is influenced not only by usual factors such as the places of activities and the travel time, but also by the factors of individual activity space and the temporal constraints. Activity space represents the spatial movement as part of a human daily experience. The suggested accessibility measure lays the foundations of this relationship of accessibility measures and the activity space. Both the proposed individual composite accessibility measure and the factor of activity space are applied in the city of Volos, using the university students’ daily diaries. The geographic information system (GIS) functions contribute significantly to the application and the evaluation of the relationship of the accessibility measures and the activity space. To sum up, the creation of a composite accessibility measure in individual level is very important in the field of spatial mobility planning, because it is an indicator of quality of life, and it is a useful measure of the social and spatial equity to urban services.
