Car Dependency Reduction Potential by Shared Autonomous Vehicle (SAV): A System Dynamic Approach

Car dependency has been perceived as a multifaceted problem for the externalities it causes. Autonomous vehicle (AV) comes with automation technology allowing people to not drive at certain levels. Despite the expensive purchase price of AV, it offers several promising benefits. Ridesharing as one form of shared mobility has been perceived as one of the solutions proposed by scholars to reduce people’s dependency on private cars in the near future. As the use of AV as ridesharing is predicted to be normal in the future, it is reasonable to investigate the impact of shared autonomous vehicles (SAV) or driverless taxi service in convincing people to give up their private car. The SAV users come from people leaving their cars for SAV service represented by SAV fleet and waiting time. The provision of fleets directly affects the waiting time, with the higher number of fleets to meet the demand lowering the waiting time. A lower waiting time has a positive impact on increasing SAV users. This research aligns with SDG 11 by providing sustainable transport for a resilient and sustainable city
