Want a worry-free trip? Seeking the optimal travel paradigm in view of public-to-individual risk perception
Published 2025-06-01“…Using Xinjiang province as a case study, empirical analysis reveals several key findings: (1) Individual travel profiles are associated with various factors that significantly influence risk perceptions, with factors such as travel expenditure and duration exerting the greatest impact, this coincides with the common perception; (2) Other factors, including traveling in non-autumn seasons, traveling with friends, going by cruising, cycling, self-driving, staying at three-star hotels on the northern and central area of Xinjiang, and following linear and circular routes, substantially reduce tourism risk perception; and (3) Discernible differences in travel plans between males and females emerge when their risk perceptions are low. …”
