1. A method for setting up a movement model of a road user for a transition from running to walking or standing or vice versa, the method comprising: at each of a plurality of moments over a period of time, reading in, by processing circuitry, a respective current movement vector of the road user, to obtain a plurality of movement vectors; using, by the processing circuity, the plurality of movement vectors to obtain a characteristic movement value of the road user for the period of time; and ascertaining, by the processing circuitry, the movement model using the movement value; wherein as the characteristic movement value, an average acceleration for at least one characteristic movement sequence of the road user and speeds typical for this are ascertained continuously over a longer time period to prepare the movement model that is valid for the road user, and wherein the characteristic movement sequence represents the transition from running to walking or standing or vice versa.
