### Claim 3 (depends on 1)

The apparatus of claim 1, wherein the determination device determines, as the control vehicle, a vehicle located in a rotation direction of the emergency vehicle by comparing a location of the emergency vehicle with a location of the respective vehicles.

### Claim 4 (depends on 1)

The apparatus of claim 1, wherein the determination device determines, as the control vehicle, a vehicle, a traveling lane of which is to be changed to a traveling lane of the emergency vehicle, by determining a location and an expected traveling path of each vehicle.

### Claim 5 (depends on 1)

The apparatus of claim 1, wherein the controller calculates the expected approach time of the emergency vehicle to the control vehicle, based on a distance between the emergency vehicle and the control vehicle, a speed of the emergency vehicle, or the maximum speed limit of a relevant road.

### Claim 6 (depends on 1)

The apparatus of claim 1, wherein the controller generates a control message for each step based on the expected approach time of the emergency vehicle.

### Claim 7 (depends on 6)

The apparatus of claim 6, wherein the controller:
generates an avoidance and warning message when the expected approach time of the emergency vehicle is less than a first time;
generates an avoidance message when the expected approach time of the emergency vehicle is the first time or more and less than a second time; and
generates a warning message when the expected approach time of the emergency vehicle is the second time or more.

### Claim 8 (depends on 1)

The apparatus of claim 1, wherein the controller determines a lane, which is to be changed, of the control vehicle, based on locations of vehicles traveling between the control vehicle and the emergency vehicle, when the traveling speed of the control vehicle is the reference speed or more.

### Claim 9 (depends on 1)

The apparatus of claim 1, wherein the control message includes:
at least one of a location of the emergency vehicle, the expected approach time of the emergency vehicle to the control vehicle, an avoidance direction of the control vehicle, and lane change information of the control vehicle.

### Claim 10 (depends on 1)

The apparatus of claim 1, wherein the communication device receives traveling data of the emergency vehicle from a management server which provides the traveling data of the emergency vehicle, and
wherein the determination device determines the expected traveling path of the emergency vehicle based on the traveling data of the emergency vehicle.

### Claim 11 (depends on 1)

The apparatus of claim 1, wherein the controller:
determines an avoidance direction of the control vehicle; and
generates the control message for the control vehicle, based on the determined avoidance direction and the determination of whether to change the lane of the control vehicle.

### Claim 12 (depends on 11)

The apparatus of claim 11, wherein the controller determines the avoidance direction of the control vehicle, based on the rotation direction or a movement direction of the emergency vehicle.

### Claim 13

A method for controlling avoidance of an emergency vehicle, the method comprising:
receiving traveling data from vehicles traveling in a specific section on an expected traveling path of the emergency vehicle;
identifying locations of the vehicles from the received traveling data and determining at least one control vehicle based on the identified locations of the vehicles; and
determining an avoidance control time point of each control vehicle based on an expected approach time of the emergency vehicle to the control vehicle, and transmitting a control message to the control vehicle based on the avoidance control time point of the control vehicle,
wherein the transmitting of the control message includes:
determining whether to change a lane of the control vehicle; and
