Figure 8 shows the L2 switch group connection link adjustment device of the L2 switch group connection link coordination system according to an embodiment of the present invention operating in the escalation event response mode while operating in the escalation event response mode or in the quasi escalation event response mode. This is a flowchart to explain how it works.

While the L2 switch group connection link adjustment device 260 is operating in the heightened weather event response mode, the information related to the occurrence of the weather event included in the traffic-related information received from each of at least two local government transportation centers is information that is related to each other. In this case, the traffic-related information receiver 330 may be operated in a super-catastrophe weather event response mode in which the traffic-related information receiver 330 is connected to receive information through the third L2 switch group 353.

While the L2 switch group connection link adjustment device 260 is operating in the heightened weather event response mode, the information related to the occurrence of the weather event included in the traffic-related information received from at least two local government transportation centers is information that is not related to each other. In this case, the traffic-related information receiver 330 may be operated in a quasi-level weather event response mode in which the traffic-related information receiver 330 is connected to receive information through the first L2 switch group 351.

Here, the traffic received from at least two regional office traffic centers serves as a standard for whether the L2 switch group connection link adjustment device 260 operates in the super-critical weather event response mode or the semi-critical weather event response mode. The relationship between the information related to the occurrence of a weather event included in the related information is called the first relationship.

The L2 switch group connection link adjustment device 260 may determine the presence or absence of a first relationship using at least one of a first temporal association, a first spatial association, a first event type association, or a first influence association.

Temporal correlation may be a correlation between weather event-related information received from different local government transportation centers and whether the time of occurrence is similar. The closer the occurrence time, the more likely the information is to be relevant.

The first spatial correlation may be a correlation regarding how close the locations of two weather event occurrence information are. The closer the areas where two events occur, the more likely the information is to be related.

The first event type association may be an association regarding whether the types of weather events are similar to each other. For example, if two local government transit centers both report information about heavy rain, this information may be determined to be related.

The first influence correlation may be a correlation regarding whether the impact of two weather events on the surrounding area is similar. For example, if it has a similar impact, such as road delays or flooding, it is likely to be highly relevant.

When the L2 switch group connection link adjustment device 260 operates in the heightened weather event response mode or the super-critical weather event response mode, it does not operate in the accident event response mode even if the traffic-related information includes information related to the occurrence of an accident event. It may also operate in a priority response mode to unexpected weather events.

While the L2 switch group connection link coordination device 260 is operating in the upgraded disaster event response mode, the information related to the occurrence of the disaster event included in the traffic-related information received from each of at least two local government transportation centers is information that is related to each other. In this case, the traffic-related information receiver 330 may be operated in a super-critical disaster event response mode in which the traffic-related information receiver 330 is connected to receive information through the third L2 switch group 353.

If the information related to the occurrence of a disaster event included in the traffic-related information received from each of at least two local government transportation centers is not related to each other, the L2 switch group connection link adjustment device 260 sends the traffic-related information receiver 330 to the traffic-related information receiver 330. It can operate in a quasi-level disaster weather event response mode that connects to receive information through the first L2 switch group 351.

Here, the traffic received from at least two local government transportation centers serves as a standard for whether the L2 switch group connection link coordination device 260 operates in the super-critical disaster event response mode or the semi-critical disaster event response mode. The relationship between the information related to the occurrence of a weather event included in the related information is called the secondary relationship.

The L2 switch group connection link adjustment device 260 may determine the presence or absence of a second relationship using at least one of a second temporal association, a second spatial association, a second event type association, or a second influence association.

The second temporal correlation may indicate how close two or more disaster events are in time. The higher the second temporal correlation, the higher the disaster events can be viewed as being related to each other. For example, an earthquake and tsunami that occurred at the same time can be considered to have a high temporal correlation.

The second spatial correlation may indicate how spatially close two or more disaster events are. The higher the spatial correlation, the more likely disaster events are to be related to each other. For example, landslides and floods that occurred in the same area can be considered highly spatially related.

The second event type association may indicate how similar a type of event two or more disaster events are to each other. The higher the second event type correlation, the higher the disaster events can be said to be related to each other. For example, multiple fire incidents that occurred due to the same cause can be considered to have high event type correlation.

The secondary impact correlation may indicate how much influence two or more disaster events have on each other. The higher the secondary influence correlation, the more likely the disaster events are to be related to each other. For example, multiple seismic events that cause similar amounts of damage can be considered highly impact-related.

The L2 switch group connection link coordination device 260 may determine the presence or absence of a second relationship by further considering at least one of the scale of the disaster, the cause of the disaster, the result of the disaster, or predictability.

The scale of the disaster may be information about whether the scale of the disaster event received by the two local government transportation centers is similar. If the scale is similar, there is a high possibility that the information is related to each other.

Disaster causes and disaster results may be information about whether the causes and results of disaster events are similar to each other. For example, in the case of a road collapse caused by an earthquake, the correlation is high if the causes are the same.

Predictability may be information about whether two disaster events have predictable characteristics. For example, in the case of natural disasters such as earthquakes or floods, it is highly relevant if there is information that can be predicted in advance.

When the L2 switch group connection link adjustment device 260 operates in the high-level disaster event response mode or the high-level disaster event response mode, it does not operate in the accident event response mode even if the traffic-related information includes information related to the occurrence of an accident event. Alternatively, even if the traffic-related information includes information related to the occurrence of a weather event, it may operate in a disaster event priority response mode rather than a weather event response mode.

Referring to FIG. 8, in step S810, the L2 switch group connection link adjustment device 260 may operate in an elevated wake-up event response mode.

In step S820, the L2 switch group connection link adjustment device 260 may check information included in the traffic-related information.

In step S830, the L2 switch group connection link adjustment device 260 may determine whether information related to the occurrence of a weather event included in traffic-related information received from each of at least two local government traffic information centers is information related to each other. .

If the information is related to each other, step S840 may be performed subsequently, and if the information is not related to each other, step S850 may be performed subsequently.

In step S840, the L2 switch group connection link adjustment device 260 may operate in a super-critical weather event response mode.

In step S850, the L2 switch group connection link adjustment device 260 may operate in a semi-elevated weather event response mode.
