In order to study the satisfaction of the elderly in bus travel under the influence of the epidemic and to improve the bus travel conditions of the elderly, based on the traditional passenger satisfaction index model, the latent variable "safety perception under the influence of the epidemic" was added to reflect the psychological changes of the elderly in bus travel due to the epidemic, and the partial least squares structural equation model of the elderly"s bus travel satisfaction under the impact of the epidemic is constructed. Taking the elderly people in Nanchang City as an example, we evaluated their satisfaction with bus travel under the influence of epidemic, verified the rationality of the constructed model, and concluded that the satisfaction of elderly passengers with bus travel is mainly affected by the perceived quality and the perceived safety under the influence of epidemic, with path coefficients of 0.474 and 0.219, respectively. At the same time, using the importance and performance analysis, focusing on the improvement priority of the subordinate items of the perceived quality and the perceived safety under the influence of epidemic subordinate items improvement priorities, the results show that the overall quality of bus services for the elderly in Nanchang is low and needs to be improved. The aspects that need to be focused on improvement are: the degree of driver"s compliance with epidemic prevention measures, the density of passengers in the bus, the ventilation in the bus, the sensitive behavior of other passengers and other passengers" sensitive behavior, etc., which provide a basis for further improving the satisfaction of elderly people"s bus trips.
