A control signal for controlling the flashing light of 602 may be generated and transmitted to the walking signal light 602. This is to provide time for pedestrians to safely cross the crosswalk. The first time can be arbitrarily set by the administrator.

As another example, when receiving a detection signal transmitted while the green light of the walking signal light is turned on, the control device 106 causes the speaker 604 to output a guidance message for guiding the remaining lighting time of the green light. The control signal may be generated and transmitted to the speaker 604. This is to provide pedestrians with information about the remaining lighting time of the green light, thereby helping pedestrians to make more efficient judgments about crossings.

As another example, when the green light of the pedestrian traffic light is turned on and the remaining lighting time of the green light is shorter than the preset second time, the control device 106 causes the speaker 604 to cross the pedestrian crossing. The control signal for controlling to output a warning message to prevent the generation can be generated and transmitted to the speaker 604. The second time may also be arbitrarily set by the administrator.

The lighting device 104 receives the detection signal through the second RF communication unit 114 and transmits it to the control device 106.

The control device 106 checks that the driver is in the vehicle through the received detection signal, and then generates and transmits a control signal for controlling the driving of the electric and electronic device installed in the vehicle.

For example, when the sensing signal is received, the control device 106 may generate a control signal for controlling the electrically driven starting device 702 to be driven and transmit the control signal to the starting device 702. Accordingly, the vehicle can be started only when the driver gets in the driver's seat.

As another example, when the detection signal is received, the control device 106 may generate and transmit a control signal for controlling the lighting device 104 to be in an on state. In this case, the control device 106 may generate / transmit a control signal for the lighting device 104 only when the lighting from the outside becomes lower than the preset threshold.
