In the light of the increasingly severe traffic congestion in the city, the rising number of private cars on the road and the low occupancy rate of those cars, this paper explores the current legal obstacles to carpooling and proposes “neighborhood carpooling” as an innovative mobility project aimed at alleviating traffic pressure in the areas around residential districts and reducing the use of private cars. The paper begins by introducing the preparatory investigation, consultation and scheme design process, and then elaborates on the series of measures undertaken to ensure that the project runs smoothly, including the formulation and distribution of the proposal, establishment of carpooling stations, registration and management of carpooling information, signing of the voluntary undertakings, design of the carpooling stickers and encouragement of public participation through the media. The analysis of different data on the actual practice of carpooling and the results of the media survey shows that the “neighborhood carpooling” project can indeed reduce private car use and has achieved certain social benefits through media publicity. Finally, the paper points out that with the guarantee of the two-level management system involving the community administrative committee and the residents’ committees, effective community organization is the key to the successful operation of the project.
