The step S2300 can determine whether the vehicle 30 is detected in the warning section 520 after the warning section 510 when the vehicle 30 is not detected in the step S2100.

At this time, when the vehicle 30 is detected in the warning section 520, a warning sound is transmitted through the avoiding speaker 310 to the operator 50 with the second step warning as shown in step S2400.

The step S2500 can determine whether the vehicle 30 is detected in the danger zone 530 after passing through the warning zone 520 when the vehicle 30 is not detected in the step S2300.

At this time, if the vehicle 30 is detected in the danger zone 530, the operator 50 can perceive the danger through the vibration device 400 worn by the worker 50 with the three-step warning as in step S2600 .

The driver of the vehicle 30 approaching the construction section 40 can recognize the dangerous situation through the warning speaker 320. [

In step S2700, it is determined that the vehicle 30 is not approaching when the vehicle 30 is not detected in step S2500, and the detection of the vehicle 30 can be terminated.
