Abstract [en]

Accessibility has conventionally been measured and evaluated ignoring user perceptions in favor of focusing on travel time and distance to a number of pre-determined destinations. Acknowledging this gap, we recently developed a scale for perceived accessibility PAC (Lättman, Friman, & Olsson 2016b) aimed at capturing the individual perspective of accessibility with a certain travel mode. In this paper, we 1) further develop the PAC measure of perceived accessibility in order to capture how easy it is to live a satisfactory life with the help of the transport system, 2) compare levels of perceived accessibility between residential areas and main travel modes, and 3) compare residents’ perceived accessibility to the objective accessibility level for the same residential area. Data from 2711 residents of Malmö, Sweden show that perceived accessibility is consistently different from objective accessibility across 13 residential areas, with minor differences in levels of perceived accessibility between areas. Surprisingly, bicycle users rate their accessibility significantly higher than those who mainly use the car or public transport for daily travel, contrary to objective accessibility assumptions. These differences point at the importance of including perceived accessibility as a complementary tool when planning for and evaluating transport systems.

2018 (English)Doctoral thesis, comprehensive summary (Other academic)
Abstract [en]

This thesis fills a gap in contemporary transport research and planning as it introduces perceived accessibility as a theoretical and methodological concept for incorporating the individual dimension of accessibility in current practice. Perceived accessibility is defined as “how easy it is to live a satisfactory life with the help of the transport system”, and is proposed as a complement to objective measures and understandings of accessibility.

The thesis includes three studies. Study I developed a measure for capturing perceived accessibility with a specific transport mode, based on theories and conceptualizations of accessibility. Study II looked at determinants of perceived accessibility, and Study III further developed the measure of perceived accessibility to include actual travel (combinations of transport modes), and explored the relation between perceived accessibility and objectively measured accessibility for the same geographical area in Sweden. In all, the thesis provides background ideas and theory on perceived accessibility, and a validated quantitative approach to capturing perceived accessibility in day-to-day travel. Empirical findings further support the complementary nature of the approach and results indicate that assessments of perceived accessibility may be helpful in determining where to direct interventions aiming at improving accessibility by evaluating different transport modes or different segments of individuals. The method developed for capturing perceived accessibility shows merit in contributing to further theory development on accessibility by its ability to identify determinants of perceived accessibility and its potential in identifying segments of the population that experience significantly lower accessibility than other groups, and thus are at risk of experiencing social exclusion or suffer from transport disadvantage.

Abstract [en]

This thesis introduces perceived accessibility as a theoretical and methodological concept for including the individual dimension of accessibility in transport research and planning. Perceived accessibility is defined as “how easy it is to live a satisfactory life with the help of the transport system”, and as it captures individual experiences and abilities, it is proposed as a complement to objective measures and understandings of accessibility.

The thesis includes three studies. Study I developed a measure for capturing perceived accessibility with a specific transport mode, based on theories and conceptualizations of accessibility. Study II looked at determinants of perceived accessibility, and Study III further developed the measure of perceived accessibility to include actual travel (combinations of transport modes), and explored the relation between perceived accessibility and objectively measured accessibility for the same geographical area in Sweden. In all, the thesis provides background ideas and theory on perceived accessibility, a validated quantitative approach to capturing perceived accessibility in day-to-day travel, and empirical findings supporting the complementary nature of the approach and its potential to differentiate between individuals.
