Aimed at the problem that the significant differences in the elderly travel behavior characteristics under different activities can’t be explained well by the existing travel-based statistical analysis methods, this paper analyze the elderly travel behavior based on the date of 407 effective elderly travel questionnaire surveys and 54 follow-up interviews in Kunming. The travel behavior characteristics based on activities are analyzed. The sensitivity of travel characteristic parameters is analyzed by using the structural equation model method. The results show that the differences of personal and family attributes, there is no significant sensitivity on the travel behavior of the elderly. In addition to the special restrictions by physical conditions, travel behavior with a strong sensitivity to the activity. Mainly have the following conclusions. Firstly, leisure activities with a strong reliance on the bus, the travel distance and activity duration are longer. Shopping activities with preference on foot, travel distance and activity duration are shorter. Secondly, in addition to going to hospital and picking up children, departure time is not sensitive to travel purpose, but departure time with a strong sensitivity to travel mode. The third, activity duration with a strong sensitivity to travel distance, trip times and travel mode.
