Another embodiment of the present invention will be described with reference to the drawings.

3 is a flowchart illustrating a method of operating in an intersection safety system according to another exemplary embodiment of the present invention.

The road sign bottle 100 turns on the vehicle guidance light in conjunction with the intersection signal system (S301). Then, the road sign bottle 100 checks whether the vehicle invaded the guide line (S303). If the vehicle invaded the guide line, the road sign bottle 100 transmits the invasion signal to the signal system module 200 (S305).

The signal system module 200 receives an invasion signal from the road sign bottle 100 to count the number of invasion of the vehicle (S307). The signal system module 200 transmits the counted number of violations of the vehicle to the intelligent transportation system 400. At this time, the signal system module 200 may transmit the number of invasion to the intelligent transportation system 400 when the counted number of invasion of the vehicle reaches a predetermined number or more.

The embodiment of FIG. 3 is preferably applied when the intersection signal of the signal system module 200 is a preliminary signal, that is, when the color of the induction lamp is yellow. This is because confusion of drivers can be prevented by not changing the color of the yellow induction lamp even when the guideline invades the vehicle.

FIG. 5 is an embodiment of a right turn signal at a double left turn intersection of a one-way four lane road, and FIG. 6 is an embodiment of a right turn signal in the case of a single left turn lane on a one-way four lane road.

In FIG. 5 and FIG. 6, the signal system is a normal left turn normal signal, and since there are no vehicles invading the guide line, the road sign bottle 100 is displayed in white.

7 and 8 are different from the embodiments of FIGS. 5 and 6, in which straight roads are arranged in a line, and thus, road marking bottles indicating a separate straight guide line are not installed. FIG. 7 is an embodiment of a right turn signal at a double left turn intersection of a one-way four lane road, and FIG. 8 is an embodiment of a right turn signal in the case of a single left turn lane on a one-way four lane road.

In the embodiment of FIGS. 7 and 8, the road sign bottle 100 is displayed in white, as in the embodiment of FIGS. 5 and 6, since the signal system is a normal left turn signal and no vehicle invades the guide line.

9 is an embodiment of a yellow signal at the intersection of a one-way four-lane road. In the embodiment of Figure 9 it can be seen that the road sign bottle 100 is displayed is changed to yellow in conjunction with the signal system.

FIG. 10 illustrates an embodiment in which the road marker bottle 100 turns red when a guideline invades a vehicle at a double left turn intersection of a one-way four-lane road. In FIG. 10, the road sign bottle 100 turns red, thereby alerting not only the driver of the vehicle invading the guide line but also the drivers of the surrounding vehicles, thereby helping to drive safely.
