During the last decades, there is an interest in shifting land-use and transport planning from a mobility-based to an accessibility-based paradigm. For this reason, there is much work done on developing and incorporating accessibility indicators in planning practice. However, many researchers report that accessibility indicators, which primarily focus on aspects of land use and transport, have little or no association with the levels of accessibility that individuals experience.
This study aims to explore the association, between accessibility indicators and accessibility levels experienced by individuals, using newly acquired data regarding the levels of accessibility which individuals experience for carrying out various everyday activities (visiting work/school, grocery stores, cafés, restaurants or pubs) with four main transport modes (bicycle, car, public transport and walking). The study area is the Gothenburg Region, Sweden. Data was collected through a web panel (N=1500) using a stratified random selection method. The strata consisted of 5 post code clusters which represent different locational contexts in terms of land use, transport, residential and employment density. In addition, three different accessibility indicators (shortest travel time, cumulative opportunity and gravity model) were calculated for the approximate residential, workplace and/or school location of respondents for various times of day.
Data was analyzed using multiple linear regression. The approach is highly explorative, focusing on whether different indicators or different specifications of the same indicator result in a better model fit. Results shed light on the relation between accessibility indicators and accessibility as experienced by individuals for various daily activities, by different transport modes and in different location contexts.
