Abstract:

Travel mode shift from car to dockless bike-sharing (DB) is one of the effective ways to solve traffic congestion and environmental problems. Therefore, the author surveys 308 car travelers in Nanjing, Jiangsu Province, to explore the impact of psychological factors on the modal shift from car to DB. This paper examines the impacts of perceived usefulness, perceived ease of use, perceived health value, and attitudes toward DB on the willingness to transfer by establishing a modified technology acceptance model. The study concludes that perceived health value and perceived ease of use positively impact the transfer willingness by changing the attitude towards DB, and perceived usefulness directly exerts positive impacts. The study also finds that DB can substitute cars in short-distance trips, and travelers are most likely to become potential DB users transferred from car in middistance trips. However, DB is more difficult to influence the choice of travel modes for car travelers in long distance.
