A method and device for operating an automated vehicle at a traffic intersection. The method includes: acquiring an environment of the automated vehicle including the traffic intersection; preparing an environment map based on the acquired environment, the environment map including a subdivision into grid cells, each including occupancy probabilities and velocity distributions; acquiring an updated environment of the automated vehicle; adapting the occupancy probabilities and the velocity distributions for each grid cell; determining the occupancy probabilities and velocity distributions of an expected environment in a next time step; repeatedly executing the steps until a final occupancy probability and a final velocity distribution is determined for each grid cell according to predefined criteria; determining a driving strategy for the automated vehicle as a function of the final occupancy probabilities and the final velocity distributions; and operating the automated vehicle as a function of the driving strategy.
