wherein, when the device installed in the selected vehicle refuses the request for transmission of the traffic image of the selected vehicle based on a user input, the traffic image providing unit transmits, to the first user device, a message which includes information that the traffic image request has been refused,

wherein the device installed in the selected vehicle is configured to provide a first user interface screen which includes a plurality of selectable buttons which correspond to information relating to the selected vehicle, and

wherein when a button from among the plurality of selectable buttons is selected, the device installed in the selected vehicle is further configured to provide a second user interface screen which includes a first selectable button relating to transmitting a captured image and a second selectable button relating to transmitting streaming video.

2. The server of claim 1, wherein the traffic image providing unit is configured to store the received traffic image for a predetermined period of time, and

wherein, when information relating to the selected vehicle is received from a second user device within the predetermined period of time, the traffic image providing unit is further configured to provide the stored traffic image to the second user device.

3. The server of claim 1, wherein the location information receiving unit is configured to receive information relating to the particular area, and

wherein the information relating to the particular area includes information relating to a location of the first user device and information relating to a distance between a point from which is selected from within the particular area and the location of the first user device.

4. The server of claim 3, wherein the vehicle location management unit is configured to define a substantially circular virtual area having a center which is located at the location of the first user device and a radius which is equal to the distance between the selected point and the location of the first user device, and to detect at least one vehicle located within the defined virtual area.

5. The server of claim 1, wherein the location information receiving unit is configured to receive information relating to the particular area, and

wherein the information relating to the particular area includes coordinates of a first point on a map which is displayed on a screen of the first user device and which first point is selected by a user of the first user device, and a distance between the first point and a second point which is selected from within the particular area.

6. The server of claim 5, wherein the vehicle location management unit is configured to define a substantially virtual area having a center which is located at the selected point and a radius which is equal to the distance between the first point and the second point, and to detect at least one vehicle located within the virtual area.

7. The server of claim 1, further comprising:

an emergency notifying unit which, when an emergency request is received from a notifying device among the plurality of devices, receives information relating to a location of a vehicle in which the notifying device is installed and a traffic image captured by the notifying device, and which sends the received traffic image to a predetermined destination.

17. The server of claim 1, wherein the plurality of selectable buttons includes at least one from among a button which relates to accident reporting, a button which relates to a service center, a button which relates to a gas station, a button which relates to a liquefied petroleum gas (LPG) station, a button which relates to cancelling a route, and a button which relates to a detour.

8. A user device for displaying a traffic image, the device comprising:

a location information sending unit which sends information relating to a particular area which is selected by a user to a server;

a vehicle information display unit which receives information relating to at least two vehicles located within the particular area from the server, and which displays a location of the at least two vehicles on a map;

a traffic image requesting unit which receives information relating to a selected vehicle from among the at least two vehicles, and which requests, from the server, transmission of a traffic image captured by a device installed in the selected vehicle; and

a display unit which, when the device installed in the selected vehicle accepts a corresponding request for transmission of the traffic image based on an user input, receives the traffic image from the server, and which displays the received traffic image on a screen, and which further receives information which relates to a respective location of each of the at least two vehicles which is usable for displaying each of the at least two vehicles on a map,

wherein, when the device installed in the selected vehicle refuses the corresponding request for transmission of the traffic image based on a user input, the display unit receives a message which includes information that the traffic image request has been refused and displays the received message on the screen,

wherein the device installed in the selected vehicle is configured to provide a first user interface screen which includes a plurality of selectable buttons which correspond to information relating to the selected vehicle, and

wherein, when a button from among the plurality of selectable buttons is selected, the device installed in the selected vehicle is further configured to provide a second user interface screen which includes a first selectable button relating to transmitting a captured image and a second selectable button relating to transmitting streaming video.

9. The user device of claim 8, wherein the information relating to the particular area includes information relating to a location of the user and a distance between the location of the user and a first point selected from within the particular area, and
