Abstract
In an escalator having a high-speed inclined portion, shape of an auxiliary track in a speed-changing region for steps is determined by finding a positional relationship between step link roller shafts of at least one of the steps and an adjacent step from a step speed profile representing speed of the step link roller shafts as a function of time. The shape of a riser is determined such that the riser aligns with a relative movement locus of the adjacent step by finding a relative positional relationship between the step and the adjacent step from the step speed profile.
