The rapid advancement of eVTOL technology offers a novel solution for enhancing commuting efficiency across complex geographical barriers, thereby accelerating the construction and development of 3D transportation infrastructure. However, the planning and development of an eVTOL operational network rely heavily on detailed passenger flow analysis and strategic decision-making regarding flight frequencies. This paper integrates the classic Multinomial Logit model from transportation planning to estimate route-specific passenger demand. With the objective of maximizing the global unit profit for the eVTOL operator, an optimization model for flight frequency scheduling is established. A Genetic Algorithm, tailored to the model's structure, is designed to calculate the dispatch headways for eVTOLs on each route. A case study, based on the "Xiangtan Urban Area - Zhuzhou West Railway Station - Xiangtan North Railway Station" bidirectional loop eVTOL network, validates the approach. The optimal flight frequencies for each route are derived through computations that account for competition with various transportation modes. Sensitivity analysis reveals that operators must prioritize marketing effectiveness for highly time-sensitive passengers. Furthermore, performing more flexible, dynamic flight adjustments based on accurate predictions of commuter flow is essential for comprehensively improving operational performance.

In his recent works on daily face-to-face encounters, Zahavi claims that the phenomenon of sharing involves reciprocity. Following Zahavi’s line of thought, we wonder what exactly reciprocity amounts to and how the shared experience emerges from the dynamic process of interaction. By turning to the highly specialized field of elite sports dance, we aim at exploring the way in which reciprocity unfolds in intensive deliberate practices of movement. In our analysis, we specifically argue that the ongoing dynamics of two separate flows of movement constitute a shared experience of dancing together. In this sense, moving together, in sports dance, is a practical way of understanding each other. In agreement with Zahavi, our analysis emphasizes the bi-directed nature of sharing. However, at the same time, we contribute to Zahavi’s ongoing endeavour as the special case of sports dance reveals how reciprocity can be deliberately shaped through the mutual coordination and affective bound dynamics of movement. Our article thus both pursues the methodological point that qualitative research of expert competences can constructively enrich phenomenological analysis and indicates how movement can be fundamental to the reciprocity of shared experience.

Metro driver is the prime person who is responsible for metro operation safety. The mental health of a metro driver is very important for the operation of the subway and requires the driver to keep high mental alertness to monitor the surrounding environment and also handle emergencies under uncertain or dangerous conditions. After a long-term occupational strain, a metro driver is likely to suffer from some mental health problems, such as anxiety and depression, that ultimately threaten the lives of passengers. Therefore, in this study, we focus on the psychological symptoms of metro drivers from the angle of occupational strain and neuroticism. A total of 396 metro drivers from Kunming Rail Transit Operation Co., Ltd. in China were investigated through a questionnaire survey. Symptom Checklist-90, Personal Strain Questionnaire, and NEO-Five-Factor Inventory-Neuroticism Subscale were applied to evaluate the psychological symptoms, occupational strain, and neuroticism in metro drivers, respectively. The surveyed data were analyzed by SPSS software. Based on the data, a path structural equation model was established to explore the correlation among occupational strain, psychological symptoms, and neuroticism. The results show that the scores for psychological symptoms and occupational strain are higher than the Chinese adult norm among metro drivers. The occupational strain, neuroticism, and psychological symptoms are all positively correlated in the metro drivers. Occupational stress has a direct influence on the psychological symptom, while neuroticism plays a partial mediation role between occupational strain and psychological symptoms. The results of this study can be applied to optimize the employee selection system and training system for metro operation companies.
