Abstract
An infrastructure component includes a sensor, a transmitter, and a computer communicatively coupled to the sensor and to the transmitter. The computer is programmed to, in response to receiving data from the sensor indicating an object approaching a predesignated zone, determine an estimated time until the object reaches the predesignated zone; and then instruct the transmitter to broadcast a message to nearby vehicles, the message including an identifier of the predesignated zone and the estimated time.
Claims20
A computer comprising a processor and a memory, the memory storing instructions executable by the processor to:
- in response to receiving data from a sensor indicating an object approaching a predesignated zone, determine an estimated time until the object reaches the predesignated zone;
- then instruct a transmitter to broadcast a message to nearby vehicles, the message including the estimated time an identifier of the predesignated zone, and an indicator specifying that the predesignated zone is one of currently occupied, currently unoccupied, or unknown occupancy;
- and
- select unknown occupancy as the indicator in response to data from the sensor indicating an obstruction of the view of the sensor of at least some of the predesignated zone.
An infrastructure apparatus comprising:
- a sensor;
- a transmitter;
- and
- a computer communicatively coupled to the sensor and to the transmitter, the computer programmed to:
- in response to receiving data from the sensor indicating an object approaching a predesignated zone, determine an estimated time until the object reaches the predesignated zone;
- then instruct the transmitter to broadcast a message to nearby vehicles, the message including an identifier of the predesignated zone the estimated time, and an indicator specifying that the predesignated zone is one of currently occupied, currently unoccupied, or unknown occupancy;
- and
- select unknown occupancy as the indicator in response to data from the sensor indicating an obstruction of the view of the sensor of at least some of the predesignated zone.
A computer comprising a processor and a memory, the memory storing instructions executable by the processor to:
- in response to receiving data from a sensor indicating an object approaching a predesignated zone, determine an estimated time until the object reaches the predesignated zone;
- determine an estimated standard deviation of the estimated time;
- and
- after determining the estimated time, instruct a transmitter to broadcast a message to nearby vehicles, the message including the estimated time, an identifier of the predesignated zone, and the estimated standard deviation.
