Increasing traffic is responsible for climate change and related problems such as noise and health consequences, and the car is one of the most favored means of transport for individual travel. Thus, traffic should become more sustainable. The objective of the thesis is to investigate to what extent statements made by the respondents about a hypothetical situation correspond to their actual behavior. For this purpose, a conjoint analysis approach will be applied.
The EBM model of 1995 was chosen as the theoretical basis. Here, the focus was put on the stages "environmental influences", "individual differences", "evaluation of alternatives" and on "choice”. Socio-demographic data, information on current travel status, live situation, mental state and experienced feelings while traveling with the current transport mode, and aspects of personality were collected, further, respondents could choose between other transport modes than the car in two hypothetical situations, the non-choice option was also possible. A total of n=918 people participated in the web-based survey, which was conducted in Poland between December 2021 and March 2022. The data was analyzed by Partial Least Square Structural Equation Modeling (PLS-SEM) using SmartPLS V.3. The results show that mental state/experienced feelings while traveling by current mode, transport policy instruments, driver's license ownership, car sharing experience, and gender have a significant influence on transportation mode choice and current travel behavior. Thus, psychological processes are important factors to consider in sustainable transportation planning.

Zielsetzung und Themenschwerpunkte (Objectives and Key Themes)
The main objective of this PhD dissertation is to investigate to what extent statements made by respondents about a hypothetical situation correspond to their actual behavior. The research focuses on the transport behavior of Polish citizens, specifically examining the influence of economic, social, and psychological factors on their mode choice decisions. The dissertation aims to contribute to the understanding of how these factors impact sustainable transportation planning.
- The role of individual and societal factors in shaping transport behavior.
- The impact of psychological processes, such as emotions, habits, and personality traits, on mode choice.
- The effectiveness of transport policy instruments in promoting sustainable mobility.
- The potential of innovative mobility concepts, such as car-sharing and autonomous driving, to influence behavior change.
- The importance of considering well-being and flow experiences in sustainable transportation planning.
Zusammenfassung der Kapitel (Chapter Summaries)
The first chapter delves into the challenges of modern mobility, focusing on the consequences of car-based systems, such as climate change, noise pollution, and traffic accidents. It also explores the evolution of the concept of sustainability and outlines different approaches to achieving sustainable mobility. The chapter highlights the importance of considering a multi-disciplinary approach, encompassing technology, public transportation, land-use planning, and behavior change.
Chapter two examines the theories behind decision-making, contrasting rational choice theory with behavioral economics. The chapter delves into various utility theories and discusses the role of cognitive biases, emotions, and habits in shaping decisions. It presents several models, including the Theory of Planned Behavior (TPB) and the Engel-Blackwell-Miniard (EBM) model, which provide frameworks for understanding how individual and environmental factors influence consumer behavior.
Chapter three explores the methodology employed in the dissertation, focusing on the use of conjoint analysis. The chapter discusses different variants of conjoint analysis, including Traditional Conjoint Analysis (TCA), Choice-Based Conjoint Analysis (CBCA), Adaptive Conjoint Analysis (ACA), and Hybrid Conjoint Analysis. It also outlines different modeling strategies and estimation techniques, such as Logit models and Structural Equation Modeling (SEM), and explains the rationale for choosing PLS-SEM for data analysis.
Chapter four presents the results of the study, analyzing socio-demographic data, travel aspects, experienced feelings, and personality traits of the respondents. The chapter uses statistical methods, including ANOVA, chi-square tests, and factor analysis, to explore the relationships between different variables. It also presents the path diagram and path estimates of the PLS-SEM model, highlighting the significant relationships identified between various factors and mode choice behavior.
