The aim of this thesis is to define in more detail a safety factor, a factor of passage of time and an ecological behaviour factor influencing the mode choice on the Prague-Munich route in relation to railway as a reference mode, and to estimate the change in mode choice after HSR completion with emphasis on defined factors. The work qualitatively analyzes the sets of ideas and understandings of selected factors, which in turn affect the travel behavior and the mode choice. Defining these factors creates space for estimating and proposing perspectives for the development of expected travel behavior in the context of the planned HSR system on the Prague-Munich route. The presented thesis discusses and interprets the comparison of selected factors between existing modes of transport. The significance of the thesis lies in the understanding and definition of selected factors that are important for HSR planning strategies between Prague and Munich. Keywords: high-speed rail, travel behaviour, transport safety perception, perception of time, grounded theory, theory of planned behavior

Autonoma bilar är ett utav de mest efterlängtade teknologierna som hastigt utvecklas i världen idag. De autonoma bilarna har redan tillämpats på vägarna idag och kommer med stor sannolikhet att fortsätta tillämpas i framtiden med de fördelar som de tillför. Men trots alla fördelar så kan samhället fortfarande känna sig osäkert på ifall det faktiskt kan förlita sig på fullt autonoma bilar. Det gäller att människorna känner sig säkra både när de sitter i bilen och när de befinner sig i den omgivande trafiken. Studien undersöker ifall kön, ålder, tillit och vetskap har en påverkan i hur människor i det svenska samhället uppfattar säkerheten med autonoma bilar i trafiken. En kvantitativ forskningsmetod i form av ett webbaserat frågeformulär användes för att samla in data. Frågeformuläret besvarades av totalt 265 respondenter mellan åldrarna 18-50+ där 121 var män och 144 var kvinnor. Den data som samlades in analyserades sedan genom den statistiska plattformen SPSS Software. Studien rapporterade att inget samband kunde påvisas mellan kön och säkerhetsuppfattningen utav autonoma bilar och likaså för faktorn ålder. Däremot upptäcktes ett samband för både faktorerna tillit och vetskap. / Autonomous cars are one of the most anticipated technologies that are rapidly evolving in the world today. The autonomous cars have already been applied on the roads today and will most likely continue to be applied in the future with the benefits they bring. But despite all the benefits, the society can still feel insecure about whether it can actually rely on fully autonomous cars. It is important that people feel safe both when they are in the car and when they are in the surrounding traffic. The study examines whether gender, age, trust and awareness have an impact on how people in the Swedish society perceive the safety of autonomous cars in the traffic. A quantitative research method in the form of a web-based questionnaire was used to collect data. The questionnaire was answered by a total of 265 respondents between the ages of 18-50+ of which 121 were men and 144 were women. The data collected was then analyzed through the statistical platform SPSS Software. The study reported that no association could be indicated between gender and the safety perception of autonomous cars and also for the factor age. However, a correlation was discovered for both factors trust and awareness.
