Whether the type of high-speed railway transition curves is suitable or not affects a train's running stability and passengers' comfort directly. The lateral change of acceleration (LCA) plays an important role in determining the transition curve parameters. Based on vehicle movement dynamics, the motions with positive or negative acceleration are taken into account to deduce the equation of lateral change of the vehicle acceleration. The LCA of several common transition curves were compared in five different motion models. The results show that the LCA which considers motion with positive or negative acceleration can be used for the optimization of high-speed railway transition curves as a theoretical basis.
