Abstract [en]

In order to plan for, and achieve, a sustainable and accessible transport system, research and policies alike recognize a need to implement and enhance alternative transport options in favor of the private car. Moreover, these sustainable alternatives need to offer sufficient levels of accessibility regardless of where people live or work. We present and discuss an approach for capturing and evaluating perceived accessibility, with the ability to differentiate between individuals. Levels of perceived accessibility are compared before and after a fictive car use restriction, and between residential areas, using data from 2711 residents of Malmö, Sweden. A main conclusion is that levels of perceived accessibility become significantly lower for car users when they are limited in their options for daily travel. The difference is more substantive for frequent car users, who already travel less by sustainable modes today. There are also significant differences in levels of perceived accessibility in the restricted scenario, depending on where individuals live. These novel findings may not come as a surprise, but they emphasize the importance of including and analyzing perceptions of car users when designing accessible and sustainable transport systems. The paper ends with a discussion on how to facilitate the transition from current transport systems to an inclusive and accessible system.

Abstract [en]

People are living longer than they did previously, and the proportion of older people is increasing worldwide. This rapid development will have implications for the transport system, in general, and for travel behavior and accessibility to daily activities, in particular. In recent years, both research and politics have drawn the attention of the public to issues affecting the opportunities of the elderly to participate in everyday life. The debate has so far mostly focused on health issues, with limited work having been done on the ability of the elderly to live the lives they want to considering how they travel. With this view, a theoretical model, grounded in a model of travel and subjective wellbeing was developed to explore the role of perceived accessibility in satisfaction with travel and life satisfaction. Empirical data were collected from a sample of 2950 respondents (aged 60–92) from five cities in Northern Europe (Stockholm, Helsinki, Oslo, Copenhagen, Bergen) and analyzed using partial least square structural equation modeling (PLS-SEM). The findings confirmed the link between perceived accessibility, travel satisfaction, and life satisfaction. The findings also showed the role of sociodemographic and travel attributes in perceived accessibility and satisfaction with travel, as well as the moderating effects of different age groups. We conclude that this moderating role played by age clearly indicates that we should not treat the elderly as a homogenous group in research and transport planning.

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.

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.

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.

Abstract [en]

The main purpose of this thesis is introducing and proposing perceived accessibility as an important and so far overseen complement to conventional, objective accessibility in sustainable transport. Perceived accessibility is defined as the possibilities and ease of engaging in preferred activities using different transport modes. Implications for sustainable transport planning along with possible social outcomes related to perceived accessibility are also discussed.

 

The thesis comprises two empirical studies. In Study I a psychometric measure (PAC) that captures perceived accessibility was developed and validated in three different datasets by exploratory and confirmatory factor analyses. All data was collected in Karlstad, Sweden in 2013 and 2014 with a total of 750 participants (bus travelers). Perceived accessibility is suggested as a complement to objective accessibility by contributing with the traveler perspective.  Study II aimed at examining determinants of perceived accessibility focusing on service quality aspects, feelings of safety, age, and trip frequency. Study II used the same data as Study I in a conditional process model to look at the relations between perceived accessibility and its proposed determinants. Service quality and feelings of safety were found important predictors of perceived accessibility, and safety also explains part of the effect of quality on perceived accessibility. These relationships were not dependent on trip frequency (as in how often one travels by public transport). Age also predicted perceived accessibility, and a follow-up cluster analysis showed that elderly and people in their thirties experience significantly lower perceived accessibility than other age groups.

Abstract [sv]

Denna licentiatuppsats behandlar upplevd tillgänglighet, det vill säga resenärsperspektivet på tillgänglighet, som ett viktigt komplement till konventionell (objektiv) tillgänglighet inom hållbart resande. Uppsatsen introducerar upplevd tillgänglighet och dess nytta och plats i forskningen samt implikationer för planering och utvärdering av hållbara transporter. Vidare behandlas påverkansfaktorer för upplevd tillgänglighet samt relaterade individuella utfall som subjektivt välbefinnande och social exkludering/inkludering utifrån teori och empiri.

 

Uppsatsen innefattar två empiriska studier. Studie I utvecklar och testar ett psykometriskt mätinstrument för upplevd tillgänglighet med data från tre enkät-tillfällen (n= 750) i Karlstad. Dataset 1 analyserades med explorativ faktoranalys för att få fram ett instrument som fångar upplevd tillgänglighet (PAC) och validerades därefter i två dataset. Studie II avsåg att undersöka vad som bidrar till upplevd tillgänglighet med fokus på kvalitetsattribut i resan (service quality), resenärens upplevda trygghet, samt ålder och resvana. Samma data som i studie I användes i en conditional process model för att undersöka sambanden, samt i en klusteranalys för att ytterligare undersöka skillnader i resultatet mellan olika grupper av resenärer. Resultatet visar att upplevd tillgänglighet kan ha betydelse som komplement till befintliga mätningar och utvärderingar av tillgänglighet genom att bidra med resenärsperspektivet. Ett antal påverkansfaktorer för upplevd tillgänglighet kan konstateras, däribland kvalitet samt resenärens upplevda känsla av trygghet. Betydelsen av kvalitet för tillgänglighet är densamma oavsett hur ofta man reser, däremot upplever de som reser ofta en signifikant högre tillgänglighet än de som reser sällan. Äldre resenärer och resenärer i 30-årsåldern påvisar signifikant lägre upplevd tillgänglighet.

Perceived accessibility is defined as the possibilities and ease of engaging in preferred activities using different transport modes and captures the traveller experience and perspective of accessibility. The thesis introduces an instrument for measuring perceived accessibility (PAC) along with determinants for perceived accessibility, such as feelings of safety, age, and perceived quality. Related social outcomes such as social inclusion and subjective well-being are discussed, along with possible implications for transport planning and suggestions for future research.

Abstract [en]

Perceived accessibility has been acknowledged as an important aspect of transport policy since the 70s. Nevertheless, very few empirical studies have been conducted in this field. When aiming to improve social inclusion, by making sus-tainable transport modes accessible to all, it is important to understand the factors driving perceived accessibility. Un-like conventional accessibility measures, perceived accessibility focuses on the perceived possibilities and ease of en-gaging in preferred activities using different transport modes. We define perceived accessibility in terms of how easy it is to live a satisfactory life with the help of the transport system, which is not necessarily the same thing as the objec-tive standard of the system. According to previous research, perceived accessibility varies with the subjectively-rated quality of the mode of transport. Thus, improvements in quality (e.g. trip planning, comfort, or safety) increase the per-ceived accessibility and make life easier to live using the chosen mode of transport. This study (n=750) focuses on the perceived accessibility of public transport, captured using the Perceived Accessibility Scale PAC (Lättman, Olsson, & Fri-man, 2015). More specifically, this study aims to determine how level of quality affects the perceived accessibility in public transport. A Conditional Process Model shows that, in addition to quality, feeling safe and frequency of travel are important predictors of perceived accessibility. Furthermore, elderly and those in their thirties report a lower level of perceived accessibility to their day-to-day activities using public transport. The basic premise of this study is that sub-jective experiences may be as important as objective indicators when planning and designing for socially inclusive transport systems.
