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.

(canceled) Claim: 19. A method comprising: using a visible-light camera located in a vicinity of a crosswalk that crosses a road to monitor an area in and nearby the crosswalk, the visible-light camera capturing a video of a vulnerable roadway user who is in or nearby the crosswalk; determining a location and a movement direction of the vulnerable roadway user based on the video; applying the location and the movement direction to a machine learning model running in equipment in the vicinity of the crosswalk to make a prediction that the vulnerable roadway users is about to enter the road in or nearby the crosswalk, the prediction being made prior to the vulnerable roadway user entering the road in or nearby the crosswalk, wherein the machine learning model has been trained using motion data generated in the vicinity of the crosswalk, the motion data comprising at least one of location, speed, acceleration, and heading; and before the vulnerable roadway user has entered the road in or nearby the crosswalk, causing a road sign to activate a light based on the prediction. Claim: 20. The method of claim 19, wherein the vulnerable roadway user comprises a pedestrian, animal, or cyclist. Claim: 21. The method of claim 19, comprising transmitting a warning to a device associated with the vulnerable roadway user based on the prediction, the device associated with the vulnerable roadway user comprising a wearable device or a smartphone. Claim: 22. The method of claim 19, comprising transmitting a warning to a motorized vehicle in the vicinity of the crosswalk based on the warning. Claim: 23. The method of claim 19, comprising receiving the machine learning model at the equipment from a remote server through the Internet. Claim: 24. The method of claim 19, comprising training the machine learning model at the equipment located in the vicinity of the crosswalk. Claim: 25. The method of claim 19, comprising determining the location and the movement direction based on a mapping between pixels of the visible-light camera and corresponding locations in a global representation of the vicinity of the crosswalk. Claim: 26. The method of claim 19, comprising segmenting motion data generated by the visible-light camera based on corresponding zones in the vicinity of the crosswalk. Claim: 27. The method of claim 19, comprising: applying rule-based processing at the vicinity of the crosswalk to control the road sign; while applying the rule-based processing, gathering data from sensors located in the vicinity of the crosswalk; training the machine learning model based on the data from the sensors; and based on the training of the machine learning model, transitioning from the rule-based processing to machine-learning based processing using the machine learning model. Claim: 28. The method of claim 19, wherein the machine learning model has been trained to predict a trajectory of the vulnerable roadway user based on the location and the movement direction of the vulnerable roadway user. Claim: 29. A system comprising: a visible-light camera located in a vicinity of a crosswalk that crosses a road; and a computer system located in the vicinity of the crosswalk, the computer system configured to: use the visible-light camera to monitor an area in and nearby the crosswalk, the visible-light camera capturing a video of a vulnerable roadway user who is in or nearby the crosswalk; determine a location and a movement direction of the vulnerable roadway user based on the video; apply the location and the movement direction to a machine learning model executing on the computer system to make a prediction that the vulnerable roadway users is about to enter the road in or nearby the crosswalk, the prediction being made prior to the vulnerable roadway user entering the road in or nearby the crosswalk, wherein the machine learning model has been trained using motion data generated in the vicinity of the crosswalk, the motion data comprising at least one of location, speed, acceleration, and heading; and before the vulnerable roadway user has entered the road in or nearby the crosswalk, cause a road sign to activate a light based on the prediction. Claim: 30. The system of claim 29, wherein the vulnerable roadway user comprises a pedestrian, animal, or cyclist. Claim: 31. The system of claim 29, wherein the computer system is configured to transmit a warning to a device associated with the vulnerable roadway user based on the prediction, the device associated with the vulnerable roadway user comprising a wearable device or a smartphone. Claim: 32. The system of claim 29, comprising transmitting a warning to a motorized vehicle in the vicinity of the crosswalk based on the warning. Claim: 33. The system of claim 29, wherein the computer system is configured to receive the machine learning model from a remote server through the Internet. Claim: 34. The system of claim 29, wherein the computer system is configured to train the machine learning model in the vicinity of the crosswalk. Claim: 35. The system of claim 29, wherein the computer system is configured to determine the location and the movement direction based on a mapping between pixels of the visible-light camera and corresponding locations in a global representation of the vicinity of the crosswalk. Claim: 36. The system of claim 29, wherein the computer system is configured to segment motion data generated by the visible-light camera based on corresponding zones in the vicinity of the crosswalk. Claim: 37. The system of claim 29, wherein the computer system is configured to: apply rule-based processing at the vicinity of the crosswalk to control the road sign; while applying the rule-based processing, gather data from sensors located in the vicinity of the crosswalk; train the machine learning model based on the data from the sensors; and based on the training of the machine learning model, transition from the rule-based processing to machine-learning based processing using the machine learning model.
