Abstract: To address the issues about the low popularity rate, acceptance degree and usage of car-sharing, regarding traffic traveler as the research object, Lewin metal of behavior was improved in this paper. Based on an car-sharing analysis by a questionnaire on travel behavior from the perspective of individuals, trip and information perception characteristic, influence factors of choosing car-sharing, use intensity, choosing car-sharing in future were studied by establishing three disaggregate models. The results indicate that males are more willing to choose car-sharing to travel than females. The higher the amount of schooling, travelers are more willing to choose car-sharing. Students and office workers' trip frequency is relatively low, just under 5 times a month. Travelers, who have already used carsharing for one month to 6 months, trip frequency is relatively higher, which is stabilized under 20 times a month. When car-sharing information is low, the more accurate of car-sharing information, the higher the car-sharing use intensity is. The earlier one gets the car-sharing information, the higher the car-sharing use intensity is. The larger amount of car-sharing information and the earlier the car-sharing information obtainment, non-car-sharing travelers are more willing to choose car-sharing in future. The research results can provide theoretical underpinning for studying travel choice of carsharing, and provide theory gist for relevant policy making.
