Abstract: A system uses neural networks to determine intents of traffic entities (e.g., pedestrians, bicycles, vehicles) in an environment surrounding a vehicle (e.g., an autonomous vehicle) and generates commands to control the vehicle based on the determined intents. The system receives images of the environment captured by sensors on the vehicle, and processes the images using neural network models to determine overall intents or predicted actions of the one or more traffic entities within the images. The system generates commands to control the vehicle based on the determined overall intents of the traffic entities.
