Systems and techniques for determining predicted object trajectories are disclosed. A vehicle computing system determines an initial predicted trajectory for an object detected in the environment and determine a predicted location for the object at the endpoint of the trajectory. Using a feature map of the environment, the vehicle computing system refines endpoint location based on a context for the endpoint. The system then determines a middle point of the trajectory based on the refined endpoint location and refines the middle location further based on the context for that location. The system iteratively uses one or more subsequent intermediate points and contexts along the trajectory for further location refinement(s) to generate a refined predicted object trajectory for the object and to determine trajectories for controlling a vehicle.
