1. A method for alerting traffic, the method being performed in an alert control device connected to a street light, the method comprising:
- receiving a first signal transmitted by a first device within the possession of a first individual within a proximity of the street light, wherein the first individual is one of a pedestrian and a cyclist, the first signal being received via a near field communication (NFC) technology;
after receiving the first signal, determining that the first individual intends to cross a street within the proximity of the street light; and
as a result of determining that the first individual intends to cross the street, controlling the street light to go from a normal state to a first alert state, wherein the lighting of the street light in the first alert state differs from the lighting of the street light in the normal state in order to alert passing vehicles that the first individual may be crossing the street within the proximity of the street light;
receiving a second signal transmitted by a second device within the possession of a second individual;
determining that a NFC signal from the second device has not been received; and
based on the receipt of the second signal and the determination that the NFC signal from the second device has not been received, determining that the second individual is within the proximity of the street light but does not intend to cross the street.

11. An alert control device for alerting traffic, the alert control device being arranged to be connected to a street light, the alert control device comprising:
-
a receiver configured to receive a first signal transmitted by a first device within the possession of a first individual within a proximity of the street light, wherein the first individual is one of a pedestrian and a cyclist, the first signal being received via a near field communication (NFC) technology; a processor; and a memory storing instructions that, when executed by the processor, cause the alert control device to; determine that the first individual intends to cross a street within the proximity of the street light, said determining being based on the first signal received from the first device within the possession of the first individual; as a result of determining that the first individual intends to cross the street, control the street light to go from a normal state to a first alert state, wherein the lighting of the street light in the first alert state differs from the lighting of the street light in the normal state in order to alert passing vehicles that the first individual may be crossing the street within the proximity of the street light; receive a second signal transmitted by a second device within the possession of a second individual; determine that a NFC signal from the second device has not been received; and based on the receipt of the second signal and the determination that the NFC signal from the second device has not been received, determine that the second individual is within the proximity of the street light but does not intend to cross the street. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 21, 22)

20. A non-transitory computer readable medium on which a computer program comprising computer program code is stored, the computer program code comprising instructions which, when run on an alert control device connected to a street light, cause the alert control device to:
-
determine that a first individual intends to cross a street within the proximity of the street light, said determining being based on a first signal received from a device within the possession of the first individual, the first signal being received via a near field communication (NFC) technology; as a result of determining that the first individual intends to cross the street, control the street light to go from a normal state to a first alert state, wherein the lighting of the street light in the first alert state differs from the lighting of the street light in the normal state in order to alert passing vehicles that the first individual may be crossing the street within the proximity of the street light; receive a second signal transmitted by a second device within the possession of a second individual; determine that a NFC signal from the second device has not been received; and based on the receipt of the second signal and the determination that the NFC signal from the second device has not been received, determine that the second individual is within the proximity of the street light but does not intend to cross the street.

23. A method for alerting traffic, the method being performed in an alert control device connected to a street light, the street light having a normal state, a first alert state configured to alert passing vehicles that persons may be crossing the street within a proximity of the street light, the first alert state being further configured to be triggered based on the alert control device receiving one or more near field communication (NFC) signals, and a second alert state, the second alert state differing from the normal state and the first alert state, the method comprising:
-
receiving a first signal transmitted by a device within the possession of an individual within a proximity of the street light; determining that an NFC signal from the device has not been received; and based on the receipt of the first signal and the determination that the NFC signal from the device has not been received, determining that the individual is within the proximity of the street light but does not intend to cross the street; as a result of determining that the individual is within the proximity of the street light but does not intend to cross the street, controlling the street light to enter the second alert state, the second alert state being configured to alert passing vehicles that the individual is within the proximity of the street light but does not intend to cross the street.
