Traveller decision-making process is like a black box. Several researchers (Woodworth, 1929; Moutinho, 1982; Middleton, 1994; Martin & Woodside, 2012; Laesser, 2018) attempt to reveal what is behind the process. However, there are still a lot of questions rather than answers. The ambition of the paper is not to open the black box, but relay on the previous knowledge, e.g. the MOA model (Laesser, 2018), integrated choice model (Curtale, Sarman & Evler, 2018) and focus on the outputs of the decision-making process from the perspective of mobility. It is important to understand visitors’ behaviour in terms of transportation use (Gross & Grimm, 2018) and their attitude towards the new alternative (high-speed rail) to reach their destination of interests. Thus, the paper studies travellers’ preferences. In other words, the research examines what actors determinate the travellers’ transport decisions (Dallen, 2007; Duval, 2014). The value of travel-time savings and money savings (Hergesell & Dickinger, 2013; Wardman, 2001) are considered as well. In general, the aim of the paper is to identify the current (spatial) preferences of travellers in relation to the used mode of transport. Precisely, it estimates future changes in preferences due to the introduction of high-speed rail (HSR) in the case of the Czech Republic. The paper significantly extends present knowledge about the travellers’ behaviour in the context of high-speed rail as a mobility alternative. Concerning the methodology, the quantitative approach survey is based on primary data collected in summer season (from June to August) in Jihlava, the focal point of the main traffic corridor between Prague, the capital city, and Brno, the second largest city – the node of the direction to Vienna (AT) and Bratislava (SK). The questionnaire covers the basic geographical information about travellers; the motivation of their travel; the used means of transport; the list of factors that potentially motivate travellers to swap for HSR; SP Experiment with 3-choice tasks (personal vehicle, couch, HSR); questions testing money savings and questions about traveller’s profile. The results of the research verify two posed hypotheses. H1: Price and time will take the predominant position within factors that determinate the travellers’ decisions. H2: The traveller’s preference in mobility alternatives will be closely bound to the purpose of travel.
