Abstract
The generation and/or use of probabilistic heat maps for use in predicting the behavior of entities in an environment is described. In an example, a computing device(s) can receive sensor data from sensors of a vehicle in an environment. The computing device(s) can determine, based at least in partly on the sensor data, a location of an entity in the environment, and a first characteristic associated with the entity or the environment (type, velocity, orientation, etc.). The computing device(s) can access, from a database, a heat map generated from previously collected sensor data associated with the environment. The computing device(s) can perform a look-up using the heat map based at least partly on the location of the entity and the first characteristic, and can determine a predicted behavior of the entity at a predetermined future time based on a pattern of behavior associated with a cell in the heat map.
