First Claim
1. A method comprisingat equipment that is on board a moving ground transportation entity, receiving safety messages from one or more of (a) roadside equipment located at intersections or along roadways, and (b) other ground transportation entities, including vulnerable road users,the safety messages from the one or more of the roadside equipment and the other ground transportation entities including information about the location, heading, speed, and predicted future path of one or more of the ground transportation entities,at the equipment that is on board the ground transportation entity, receiving information about conditions nearby the ground transportation entity from sensors on the ground transportation entity,(a) acquiring training data from one or more of the roadside equipment and ground transportation entities, the training data representing patterns of motion, behaviors, and intentions of ground transportation entities, and training an artificial intelligence model using the training data to produce a trained artificial intelligence model representing motion, behaviors, and intentions of ground transportation entities, or (b) accessing such an artificial intelligence model that has been trained using training data, or both (a) and (b), andat the equipment that is on board the ground transportation entity, applying at least one of the received safety messages and received information about conditions nearby the ground transportation entity to the trained artificial intelligence model to generate predictions of at least one of intent and trajectory of one or more other ground transportation entities including vulnerable road users.

Abstract
Among other things, equipment is located at an intersection of a transportation network. The equipment includes an input to receive data from a sensor oriented to monitor ground transportation entities at or near the intersection. A wireless communication device sends to a device of one of the ground transportation entities, a warning about a dangerous situation at or near the intersection, there is a processor and a storage for instructions executable by the processor to perform actions including the following. A machine learning model is stored that can predict behavior of ground transportation entities at or near the intersection at a current time. The machine learning model is based on training data about previous motion and related behavior of ground transportation entities at or near the intersection. Current motion data received from the sensor about ground transportation entities at or near the intersection is applied to the machine learning model to predict imminent behaviors of the ground transportation entities. An imminent dangerous situation for one or more of the ground transportation entities at or near the intersection is inferred from the predicted imminent behaviors. The wireless communication device sends the warning about the dangerous situation to the device of one of the ground transportation entities.
