With the fast development of real-time matching platforms such as Didi, ridesharing becomes popular around the world in recent years. Different from the USA where most people drive alone to travel, this paper points out that its impacts on car increments is two-sided in China where public transit is popular. On one hand, ridesharing provides an attractive travel mode, therefore may persuade some travelers to give up their vehicle purchase plan; on the other hand, the cost of private car driving is shared, so that some travelers who originally cannot afford a car may be induced to purchase cars. In this paper, we model the car-purchasing and travel mode choices of travelers whose value of time is heterogeneously distributed and increases with time. Based on the model, we demonstrate the impact of ridesharing on the variance of car increments through numerical examples. As shown in our numerical example, ridesharing may accelerate or decelerate the increase of car ownership, depending on the design of driver-rider cost sharing strategies.
