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.

A computer-implemented method of managing a fleet of autonomous vehicles is provided. The method comprises receiving at least one request for a passenger journey from a client device associated with a passenger and allocating an autonomous vehicle to the passenger from the fleet. Confirmation that the autonomous vehicle has reached the passenger is then received and one or more vehicle status signals are received from the autonomous vehicle. Subsequently, the autonomous vehicle is authorised to proceed with the passenger journey in dependence on the vehicle status signals.
