When is Perceived Accessibility Over- or Underestimated by Accessibility Indicators?

Abstract

This study delves into mismatches between accessibility indicators and perceived accessibility across transport modes for the case of grocery shopping. Conducted in Gothenburg, Sweden, the study combines a web panel survey with 1,423 participants and detailed location-based accessibility indicators. Findings reveal mismatches, with analyst’s overestimation (when the accessibility indicator is high, despite low perceived access) and analyst’s underestimation (low indicator, high perceived accessibility) varying across transportation modes. Notably, underestimation is prominent for car accessibility. Multinomial logistic regressions identify key variables influencing these mismatches, such as parenting status, education level and habitual car use.
