The network 100 may be implemented in a variety of ways. For example, the network associated with embodiments of the present invention may include a social network.

Hereinafter, a social network related to one embodiment of the present invention will be described.

3 is a conceptual diagram for explaining a social network related to one embodiment of the present invention.

Social networks is one of the research fields of web science. It refers to a social relation structure that is created by interdependent ties between individual nodes or individuals as a single node. In this case, all the nodes are individual subjects in the network, and ties are the relationships between the nodes (above, Wikipedia).

The social network according to the present invention may include at least one second node B, C, D, E, F, and B having a relationship with a first node A, centering on a first node (node A) G, H, I).

The first and second nodes A, B, C, D, E, F, G, H and I may be a specific location, a specific road, a specific building, a specific user,

For example, if the first node A is a specific user, another user or terminals having a relationship with the user may configure the social network 100 together with the specific user as a second node.

When the first node A is a specific road, other roads, buildings, terminals or users having a relationship with the specific road may constitute the social network 100 together with the specific road as a second node .

When the first node A is a specific building, another building, road, terminal or users having a relationship with the specific building can configure the social network 100 together with the specific building as the second node .

When the first node A is in a specific location, another location, a road, a building, a terminal or a user having a relationship with the specific location is configured as a second node with the specific location to configure the social network 100 .

Since the social network 100 according to the present invention is formed around a specific node, various social networks 100 can be configured according to a specific node. For example, when the specific node is a 'southern ring road', a 'star tower', a 'Gangnam station', a 'Yeouido', etc., the information networks 500 formed around the specific nodes may be different from each other. At this time, although each of the information networks 500 may not coincide with each other, some of other nodes included in one information network 100 may be included in another information network 100 as well. For example, assuming that the user A and the user B are included in the network 100 formed around the node 'southern circuit road', the user A and the user B are connected to the network 100 formed around the node ' And user C may be included. That is, the node A may be included both in the network formed around the 'southern ring road' and in the network formed around the 'star tower'.

At this time, the nodes A, B, C, D, E, F, G, H, and I may preferably have corresponding location attributes. For example, when the nodes are a specific location, a specific road, or the like, the location of the specific location, the specific road, and the specific building may be a location attribute corresponding to the node, The current location of the particular terminal or the specific user may be a location attribute corresponding to the node.

In addition, the first node A can be distinguished as a static node and a dynamic node, which means a node whose positional property corresponding to the specific location, specific road, specific building, etc. does not change, A node means a node whose positional attribute, such as the specific user or the specific electronic device, can be changed over time.

The first node A and the second nodes B, C, D, E, F, G, H, The nodes are directly related to the first node A, but the nodes D and H are indirectly related to the first node B (in the drawing, a line connecting nodes and nodes is a node In which case they are directly related. For example, a node D is associated with the first node A via a node I or a node G, and the node H is associated with the first node A via a node B or a node F have.

In this case, the nodes B, C, E, F, G and I define a primary relation with the first node A, and the nodes D and H are connected to the first node A I have a relationship. Of course, although not shown in the figure, there is no relationship with B, C, E, F, G, and I. However, if there is a node that is associated with any one of the D and H nodes, Can be defined to have a cubic relationship with the first node (A).

According to an embodiment of the present invention, the relationship between the first node A and the second nodes B, C, D, E, F, G, H, The positional relationship between the first node A and the second nodes B, C, D, E, F, G, H, In other words, when the B user (second node) sets the reverse osmosis station (first node) as a region of interest, a predetermined relationship may be formed between the first node and the second node by the B user's intention. On the other hand, when the terminal (second node) of the C user is located within a certain range from the Gangnam station (first node), the C user has a natural relationship with the Gangnam station (second node) Can be formed.

According to other embodiments of the present invention, the first node may have a specific keyword associated with the first node as its attribute, and if the information generated and uploaded through the second node includes the specific keyword, A relationship may be formed between one node and the second node. In other words, if the user D is not currently located on the southern ring road, but he / she is watching news at home and is found to have a car accident due to a fire on a part of the southern ring road, Directional congestion due to the zone fire ', the relationship with the southern ring road (first node) may be formed due to a specific keyword' southern ring road 'uploaded by the second node.

As described above, the relationship between the first node and the second node can be maintained not only statically, but also has a relationship that changes continuously according to the positional relationship, the keyword relation, etc., The network can generate information highly relevant to a particular node.

In this way, the existing social network can be formed only by the request between the user and the user by the social relation between the user and the user, while the social network embodied by the present invention goes beyond this relationship, The relationship can be formed according to the relationship. Accordingly, various kinds of information generated and uploaded by various entities can form a social network centering on various traffic information or a specific location that may be of interest in a specific area. According to this characteristic, the nodes constituting the social network according to the present invention can be continuously changed over time.

According to an embodiment of the present invention, the social network 100 can be formed as described above, and the second terminal 400 can receive various information through the social network 100.

However, the idea of the present invention is not limited to the case where the first and second terminals 300 and 400 and / or the electronic devices corresponding to the first node and the second nodes are implemented by the navigation device 10.

6 is a signal flow diagram illustrating operations of a terminal and a server according to an embodiment of the present invention. As shown in the figure, the terminal 10 and the server 20 according to an embodiment of the present invention can exchange information and guide the route more effectively.

The terminal 10 may be in the state that the route is running (S210).

The route travel means that the route to the destination is set, and may be a term corresponding to the free travel where the route is not set. In the route running state, the terminal 10 can perform the route guidance according to the set route.

While the terminal 10 is performing the guidance on the route in the route traveling state, the server 20 may acquire a traffic event (S220).

The traffic event may be an event related to the variation of the traffic situation associated with the navigation terminal 10. For example, it may be the case that information indicating that a traffic accident occurred on the set route is obtained. Traffic events can be acquired using a Transport Protocol Experts Group (TPEG) and / or a social network type service that acquires traffic information using a DMB network.

The social network type service may mean a method in which the server 20 acquires various kinds of information related to traffic from a plurality of terminals 10. [ Using a social network type of service, it is possible to transmit to a specific user substantially in real time. For example, the server 20 can acquire traffic information such as congestion, delay, and smoothness from the terminals A to C. When there is a terminal D that requires traffic information, the server 20 needs a terminal D Can be selectively transmitted to the D terminal. For example, when only the C-terminal among the A-C terminals is on the path of the D-terminal, it means that the information obtained from the C-terminal can be transmitted to the D-terminal.

When a traffic event is acquired using a social network method, it is possible to quickly recognize whether or not a sudden traffic-related event occurs. In the case of using TPEG, a certain processing time may be required until information such as traffic flow is collected and reflected. However, when the social network system is used, since the information uploaded by the user is transmitted to the server 20 in real time, the change of the traffic situation can be detected quickly. The server 20 can acquire the occurrence of a traffic event such as the occurrence of a traffic accident through the information uploaded by the user of each terminal.

When the traffic event is obtained, a step S230 of generating a new route may be performed.

The setting of the new route may be the operation of the server 20 corresponding to the occurrence of a traffic event such as the occurrence of a traffic accident. For example, if a traffic accident occurs in front of the D vehicle that is in the course of traveling, and congestion occurs or the likelihood of occurrence of the congestion increases, the server 20 can create a new route to replace the previous route.

When a new path is created, step S240 of generating information corresponding to the path can be performed.

The information corresponding to the path may mean information to be transmitted to a specific terminal. For example, information on a newly created path itself, information uploaded by a user of another terminal using the social network service, and the like may be used.

The information corresponding to the path can be generated only for the portion that does not overlap with the previously set path. For example, when the first path from the source to the destination is changed to the second path, it means that the new second path can be created only for the new path part that does not overlap the first path. It is possible to expect a reduction in the load that may occur in the process of searching for and transmitting information due to the generation of information except for the information already provided to the terminal 10.

The second path may be generated at the terminal 10 instead of the server 20. For example, when a traffic event such as a traffic accident occurs, the server 20 can transmit the fact to the terminal 10. Upon acquiring the occurrence of the traffic event, the terminal 10 can generate the second route that replaces the previous first route based on the acquired information. At this time, the server 20 can selectively transmit only the information on the part where the first and second paths do not overlap with each other, to the terminal 10, among the information acquired through the social network method. Since the data to be transmitted from the server 20 to the terminal 10 is minimized, the transmission / reception load of data can be reduced.

The range of information corresponding to the path may be related to the current position of the terminal to transmit the information. For example, the range of information can be determined according to various criteria such as information within a certain radius of a specific terminal, information within a predetermined distance forward of a specific terminal, information on a path, and the like. The server 20 can search for information within a range set for transmission to the terminal 10. [

And the step of transmitting the generated information (S250) may be performed.

The generated information can be transmitted to the communication unit 110 of the terminal 10 using the second communication unit 210 of the server 20 (FIG. 5). Transmission of the generated information can transmit information optimized for the terminal 10 to the terminal 10, unlike the case where the information is transmitted to an unspecified number such as the TPEG. That is, it means that the newly generated path and the information corresponding to the path can be transmitted.

Upon receiving the information, the terminal 10 can proceed to perform the route guidance according to the new route (S260).

The terminal 10 can display the transmitted route and can output the transmitted information. For example, it means that a traffic accident image occurred on the route can be displayed so that the user can recognize the traffic accident image. The user can more clearly recognize the state of the new route because the newly transmitted route and the information related thereto are also output together. The terminal 10 can display the point where the traffic event has occurred on the new route have. For example, it means that an icon corresponding to a traffic event occurred can be displayed at a specific point on the route. The user can select the displayed icon and confirm the specific contents of the corresponding traffic event.

7 is a flowchart illustrating an operation method of a server according to an embodiment of the present invention.

The server 20 receives various kinds of information from the social network 100 as described above (S100).

The received various information may include traffic related information, traffic information, information on a specific point of interest (POI), chatting information, and the like. In addition, the received various information may include at least one of position information, direction information, and time information related thereto. Further, the various information may include identification information of a user who has transmitted the various information or a terminal of the user.

The information may be information obtained from the first terminal 300. For example, the information may include information input by the user through the user input module 121 of the first terminal 300. Or the information may include acoustic information obtained by the microphone 123. [ Or the information may include image information obtained by the image acquisition module 125. [

At this time, when the first terminal 300 transmits the information to the server 20, the first terminal 300 may transmit position information and / or direction information related to the obtained information.

According to an embodiment of the present invention, the location information and / or the direction information may reflect the current location and current direction of the terminal at the time of acquiring information to be transmitted.

For example, when the first terminal 300 transmits the information to the server 20, the first terminal 300 may transmit location information related to the acquired information. The location information may reflect the location of the first terminal 300 when information is acquired by the first terminal 300. For example, when the first terminal 300 is located in the 'Yangjae Station' and the user of the first terminal 300 inputs information indicating 'Slowing from Yangjae Station toward Gangnam Station' Location information such as 'Yangjae Station' may be transmitted to the server 20 together with the information. The positional information may be obtained by the position data module 111 as described above. In addition, the location information may be transmitted in the form of text 'Yangjae Station', but may be transmitted in the form of longitude coordinates and latitude coordinates obtained by the location data module 111.

Also, when the first terminal 300 transmits the information to the server 20, the first terminal 300 may transmit direction information related to the obtained information. The direction information may reflect the direction in which the first terminal 300 is proceeding at the time the information is acquired by the first terminal 300. For example, when the first terminal 300 is proceeding from the 'Yangjae Station' to the 'Gangnam Station' on the Gangnam Dae road, the user may transmit the ' (I.e., voice communication) can be transmitted to the server 20 together with the direction information.

Alternatively, according to another embodiment of the present invention, the location information and / or the direction information may be information extracted from information to be transmitted.

For example, when the user inputs 'smooth communication between the user and the user' through the first terminal 300, the first terminal 300 extracts location information and / or direction information from the information input by the user Can be extracted. That is, the 'cue bouquet' can be extracted as the location information and the 'Kwacheon area' can be extracted as the direction information.

According to another embodiment of the present invention, the location information may reflect a location attribute assigned to a node related to the input information.

For example, if there is a 'Gangnam Station' as the first node, the first terminal 300 is a second node having a relationship with the 'Gangnam Station', and the 'Gangnam Station' The inputted information can be transmitted to the server 20 together with 'Gangnam Station' which is related position information. If the direction attribute is also given to the first node, direction information reflecting the direction attribute given to the first node may be transmitted to the server 20.

Meanwhile, when the first terminal 300 transmits the information to the server 20, the first terminal 300 may transmit time information related to the acquired information. The time information may reflect time at the time of acquisition of information to be transmitted.

Subsequently, the server 20 stores the received information in the database (S110).

The received information may optionally be stored. That is, all of the received information may be stored, and only a part of the received information may be stored. For example, the server 20 may evaluate the content of the information received through the social network 100 according to a predetermined criterion, and then selectively store only information corresponding to the criterion. This predetermined criterion can be determined by reflecting the purpose of the information to be provided from the server 20 to the navigation device 10. [ For example, when it is desired to transmit the traffic-related information to the navigation system 10, the server 20 can determine whether the received information includes the traffic-related information or not, If not, the received information can be discarded without saving. Hereinafter, the operation of the server 20 for selectively storing the received information in the database will be referred to collectively as a 'filtering operation' or 'filtering'.

In storing the received information in the database, the server 20 can map and store the map data for navigation. At this time, the server 20 can map the received information to the map data using the location information included in the information.

The information may be classified and stored according to the location information. For example, the information may be classified and stored according to administrative districts such as city / province / district, and may be stored separately for each road such as an outer ring road, a southern ring road, and an Olympic road. Or further subdivided to be classified and stored for a predetermined road section such as an A-B section of an outer ring road and a C-D section of a southern ring road.

Further, the information may be classified by considering further the direction information included in the information. For example, the A direction of the A-B section of the outer ring road, or the B direction of the A-B section of the outer ring road.

On the other hand, the server 20 may add the evaluation information to the information and store the evaluation information together. The evaluation information may be representative of the reliability of the information. For example, the higher the rating information, the more reliable the information is, and the lower the rating information, the less reliable the information.

The manner in which the evaluation information is given to the information may vary widely. For example, it can be calculated in consideration of the user who transmitted the information or the evaluation information given to the terminal. Alternatively, when the information includes traffic-related information, the evaluation information may be calculated in consideration of a result of comparison with traffic information provided from another traffic information providing server.

Subsequently, the server 20 receives the condition from the second terminal 400 (S120).

The condition is generated in the second terminal 400, and the navigation 10 can be generated by various algorithms. A concrete example of the second terminal 400 generating the condition will be described later.

The condition may include at least one of a specific user, a specific terminal, location, time, and direction.

According to an embodiment of the present invention, the server 20 can select some information in consideration of the received conditions. For example, when the condition information includes the position and the direction, the server 20 determines whether or not the first terminals corresponding to the position and the direction (for example, (E.g., terminals).

According to an embodiment of the present invention, at least one dynamic information group selected from a plurality of pieces of information stored in a server or a plurality of pieces of information accessible through the social network 100 . Since the dynamic information group is closely related to the conditions generated and transmitted by the second terminal 400, a specific embodiment in which the second terminal 400 generates a condition will be described below.

In consideration of the received condition, the server 20 selects some of the collected information and transmits it to the second terminal (S130).

The server 20 can select a part of the collected information in consideration of the received condition to generate a dynamic information group. Subsequently, the server 20 may transmit the information included in the dynamic information group to the second terminal 400. [ That is, the server 20 can transmit the information included in the dynamic information group configured from the collected information to the second terminal 400.

According to an embodiment of the present invention, the server 20 stores the information acquired by the first terminal 300 as it is, and transmits the information to the second terminal 400 without any processing. For example, when the driving image obtained during the driving of the vehicle by the first terminal 300 is photographed, the server 20 receives / stores the photographed image, , The image can be transmitted to the second terminal 400 without further processing.

According to another embodiment of the present invention, the server 20 stores information obtained by the first terminal 300, and then processes the information before transmitting the information to the second terminal 400 The processed information can be transmitted to the second terminal 400. There are many ways to process information. Specific methods for processing the information will be described later.

As described above, according to the embodiments of the present invention, the server 20 can collect various information from the social network 100 formed by various relationships, and among the information, It is possible to provide only the information necessary for the second terminal 400 by transmitting the selected information to the second terminal 400 in consideration of the condition information.

8 is a flowchart specifically showing a condition receiving process from the terminal.

As shown in the figure, the step of receiving the condition from the terminal (220 in FIG. 5) of the server 20 according to the embodiment of the present invention (S120 in FIG. 7) Step S140.

The user can operate without setting or setting the route. If the route is set and operated, it can be regarded as "route travel." If the route is not set, it can be regarded as "free travel".

When in the path running state, the set path can be changed for various reasons. For example, the route can be changed based on the traffic information that the user changes the route or releases the route, or is actually transmitted in real time. The navigation system 10 according to an embodiment of the present invention can collect traffic information through various means. For example, it means that not only traffic information can be collected using TPEG technology, but also traffic information generated by users of other terminals can be collected. In other words, it means that traffic information can be collected by using the social network function.

When the traffic information is collected using the social network function, the traffic information on the route that is actually set in real time can be actively collected. That is, it means that the current traffic situation can be accurately obtained from other users on the set route.

If the current route is determined to be inappropriate based on the traffic information collected using the social network function or the like, the control unit 220 of FIG. 5 may generate a new route.

When the new path is created, the control unit 220 of FIG. 5 may proceed to determine whether the previous path and the new path overlap with each other (S150).

The new path may be all or some of the paths currently set. For example, if you are currently driving a path A, you can see the path A and at least some other path B as a new path.

As shown in FIG. 9, the controller (220 in FIG. 5) can determine whether there is an overlapping area between the previous path and the new path (S152).

If there is an overlapping area, step S154 of searching for information on the non-overlapping area, and if no overlapping area exists, step S156 of searching for information on the entire area of the overlapping area.

It is determined whether the previous path overlaps part or all of the new path. Therefore, the range of information to be searched by the control unit 220 (FIG. Therefore, the search is not performed for the portion overlapping with the existing path, and the search is performed only for the portion that is not overlapped. Thus, the load can be reduced. That is, it means that the controller (220 in FIG. 5) can operate more optimally.

If it is determined that the information is overlapped, a step of determining a range of information to be transmitted (S160) may be performed.

In transmitting the information on the path portion that does not overlap the previous path among the generated new paths to the terminal, it may be necessary to determine to what extent the information is transmitted based on the position of the vehicle equipped with the terminal. For example, it may be necessary to determine whether to transmit information within a certain radial direction around the current position of the vehicle, whether to transmit information ahead of the current position of the vehicle, and so on.

As shown in Fig. 10, the step of determining the range of the information to be transmitted (S160) may include a step S162 of obtaining the current position information of the vehicle.

The position information of the vehicle can be obtained through the position data module (111 in Fig. 4). The position data module (111 in Fig. 4) can receive the radio wave signal from the satellite, as described above. The controller (170 in Fig. 4) can calculate the position information of the vehicle based on the received radio wave signal and then transmit it to the server (20 in Fig. 5). Alternatively, the controller (170 in FIG. 4) may transmit the received data of the radio wave signal itself to the server (20 in FIG. 5) and the server (20 in FIG.

When the current position information of the vehicle is acquired, the step S164 of searching information within a certain range at the present position of the vehicle can be performed.

As described above, the range from which the information is retrieved from the collected data can be determined based on the current position of the vehicle. For example, this means that information within a certain radius around the present position of the vehicle can be searched, information within a certain range ahead of the current position of the vehicle can be searched, or information near the set route can be searched.

If information within a certain range is searched based on the acquired location information, the step of transmitting information to the terminal (S 130) may be performed.

A server (20 in FIG. 5) that has retrieved information on non-overlapping areas after generating a new route based on information collected using a social network, etc., can transmit the new route to a specific terminal. The transmission to the terminal can be performed through the second communication unit (210 in Fig. 5).

The navigation device 10, which is the terminal receiving the information, can output the information to the output unit (140 in Fig. 4). For example, it means that route guidance can be performed according to information on a new route that has been transmitted, or an accident image or the like collected from a social network can be displayed.

The execution of the route guidance may be performed through a map matching process in which the existing route or the new route and the location information obtained through the location data module 111 of FIG. 4 correspond to the pre-stored map data. That is, in order to overcome the accuracy limit according to the error inherent in the position information obtained through the position data module (111 in FIG. 4), a method of estimating the accurate position corresponding to the map data is applied to the position information, It can be done.

11 is a view showing a traveling route according to an embodiment of the present invention.

As shown in the figure, the vehicle on which the terminal 10 is mounted may be present at the P1 position. In addition, the terminal 10 may be set to the first path RT1 to the destination P2 position.

Another vehicle may be traveling on the first route RT1. For example, A, B, C driver's vehicle may be running. For convenience of explanation, a driver vehicle named Annie will hereinafter be referred to as A, a driver vehicle named Ben, and a driver vehicle named Craig by C, in the following description. It is also assumed that the terminal 10 according to an embodiment of the present invention is installed in each vehicle.

In addition to the first route RT1, the vehicle may be located in the vicinity of the route. For example, the vehicle of D, E, F driver may be running. Hereinafter, a driver's vehicle named Dorothy will be denoted by D, a driver's vehicle named Edward by E, and a driver vehicle named Fred by F in the following description. It is also assumed that the terminal 10 according to an embodiment of the present invention is installed in each vehicle.

The terminal 10 mounted on the user vehicle may be performing the route guidance according to the first route RT1 at the position P1. For example, it means that the route guidance can be performed so that the vehicle passes straight through the C1 intersection, makes a left turn at the C2 intersection, and then goes straight until it passes the C3 intersection to arrive at the destination P2.

While the route guidance by the terminal 10 mounted on the user vehicle is performed, the terminals 10 installed in the vehicles A to F upload the traffic-related information to the server 20 (Fig. 5) using the social network service method . For example, it means that the terminal 10 can upload a video shot through a camera included in the image acquisition module 125 (FIG. 4) or a comment on the communication state of the vehicle. The data uploaded by the user may be stored in the database (230 of FIG. 5) of the server (20 of FIG. 5) and transmitted to the terminal (10) of the vehicle that requires the information.

While receiving the related information from the terminal 10 mounted on each vehicle, it is possible to obtain information related to an accident occurring at one point on the route. For example, it means that a traffic event (EV) has been generated based on the information acquired from the terminal of the C vehicle. The fact that a traffic event (EV) has occurred can be found through various methods described below.

The occurrence of the traffic event (EV) can be determined through analysis of the image acquired from the camera of the C vehicle. For example, it can be determined that a traffic event (EV) has occurred when a caption image of a vehicle is photographed on an image taken by a terminal 10 mounted on a C vehicle or a traffic accident image of a vehicle is photographed.

The occurrence of the traffic event (EV) may be determined through analysis of the change in the position of the C vehicle. For example, when the terminal 10 mounted on the C vehicle moves to a low speed or stops while driving, it can be determined that a traffic event (EV) has occurred.

The occurrence of the traffic event (EV) may be judged through traffic-related contents directly input by the user. For example, when a user inputs a message such as delay, congestion, or accident occurrence, it means that a traffic event (EV) corresponding thereto can be determined to have occurred.

Hereinafter, operations of a terminal and a server according to an embodiment of the present invention will be described with reference to FIGS. 12 to 14, with reference to the traffic situation shown in FIG. 11.

FIG. 12 is a view showing a display screen of the terminal, and FIG. 13 is a view showing an associated traffic image on the display screen of the terminal of FIG.

As shown in Fig. 12, information relating to route guidance may be displayed in a part of the screen. For example, a route mark ST (ST) with the car icon C as a starting point can be displayed on the map.

Related contents (SN) acquired from the server (20 in Fig. 5) may be displayed in another part of the screen. The traffic related content SN may be information obtained from the server 5 (5 in Fig. 5) from the terminal (20 in Fig. 5) mounted on another vehicle and transmitted to the terminal of the user vehicle (10 in Fig.

The traffic related content (SN) can be implemented in the form of a social network service. For example, it means that the information uploaded by other users can be shared in a form that is transmitted to a specific user substantially in real time.

The traffic related content (SN) may display information related to another user who uploaded the image (UI) of another user who uploaded the information, the name of the user (UN), and the like. Further, it is possible to display speed information (TS) of another user vehicle and position information (TA) of another user. Furthermore, messages (TI) uploaded by other users may be displayed.

Traffic-related contents (SN) can be displayed separately for each user. For example, the first to third traffic-related contents SN1 to SN3 can be displayed. Further, it goes without saying that the display position may vary depending on the distance of the user from the vehicle or the importance of the information.

Through the traffic related content (SN), the user can know that a traffic event (EV) has occurred. For example, as shown in the third traffic-related content SN3, the moving speed of the vehicle is markedly lower. Craig, who uploads the third traffic-related content SN3 through a message input by the user, It can be seen that a traffic event (EV) has occurred in the vicinity of the vehicle.

As shown in FIG. 13, the traffic image I1 may further be displayed in the third traffic-related content SN3. The traffic image I1 may be an image captured through a camera provided in Craig's C vehicle. 5), and the server (20 in FIG. 5) may have retransmitted to the terminal (10 in FIG. 4) of the user who needs the image . When the traffic image I1 is displayed, the user can more easily recognize the traffic situation.

14 is a diagram illustrating a selection process and a display process of a related image.

As shown, the user can select specific information to obtain more detailed information.

As shown in FIG. 14 (a), the user can perform an operation of selecting the traffic image I1 using the finger F or the like.

As shown in Fig. 14 (b), the controller (170 in Fig. 4) can enlarge and display the selected traffic image I1 on the screen. As the required image is enlarged and displayed, the user can more clearly confirm the related traffic situation.

15 is a view showing another traveling route of the terminal.

As shown, the server (20 in FIG. 5) can search for the second route (RT2) as an alternative route by reflecting the occurrence of the traffic event (EV).

The second route RT2 may be a route newly set by the server (20 in FIG. 5) reflecting the traffic event (EV). In other words, this means that the route may reflect a delay or stagnation of the vehicle due to the occurrence of a traffic accident. For example, it may be a route avoiding a point where a traffic event EV occurs and making a left turn at the first intersection C1 to arrive at the P2 position via the fourth intersection C4 and the third intersection C3.

The second path RT2 may overlap with the first path (RT1 in Fig. 11) in part. For example, it can be seen that the path from the current P1 position of the vehicle to the first intersection C1 overlaps the route before the change. The second control unit 220 (FIG. 5) of the server (20 of FIG. 5) may not search for the corresponding part when the paths overlap. That is, it means that the information from the current P1 position to the first intersection C1 is not searched but only the path from the first intersection C1 to the position P2 can be searched. Therefore, the overall load of the server (20 in Fig. 5) can be reduced. Further, the amount of information to be provided to the terminal (10 of FIG. 4) is reduced, and the effect of smooth communication can be expected.

FIG. 16 is a view showing an associated traffic image on another traveling route.

As shown, a video of the bypass route can be displayed on the screen of the terminal. That is, the terminal mounted on the vehicles F and D can receive and display the fourth and fifth traffic-related contents SN4 and SN5 provided by the server 20 (FIG. 5) from the server 20 (FIG. 5) do. By displaying the image of the bypass route, the user can more clearly recognize the circumstance of the bypass route.

17 is a diagram showing a state inquiring about whether or not to search for another traveling route again.

As shown in the figure, the image of the bypass route can be displayed and the user can be confirmed whether or not to change the route to the route.

18 is a view showing another example of the related traffic image on another traveling route.

As shown in the figure, it can be displayed together with comments of other users who provided the images. That is, it means that a screen can be configured and displayed in the form of a social network service. In the case of displaying a screen in the form of a social network service, comments on other users' images, blur, moving speed, and traffic conditions can be displayed together with images as described above.

FIG. 19 is a view showing the collection range of the related traffic image.

As shown in the figure, the server (20 in FIG. 5) may set the collection range of the traffic image differently depending on the case.

When the user's vehicle with the terminal is referred to as A, the server (20 in FIG. 5) can set the first area OA1 including the front side path of the vehicle as the traffic image collection area. That is, the second control unit 220 of FIG. 5 retrieves data corresponding to the first area OA1 from the database 230 (FIG. 5) and transmits the retrieved data to the corresponding terminal it means. When a traffic image is searched based on the first area OA1, a decrease in the server (20 in FIG. 5) and a communication load can be expected relatively.

The second area OA2 or the third area OA3 can be set as a traffic image collection area according to a predetermined area in front of the vehicle A. [ That is, it means that the set path and its vicinity can be set as the data collection range. Furthermore, the fourth area OA4 surrounding the vehicle A may be set as the data collection range. A wider range of data collection can provide more information to the user. Therefore, it can be used as a data that enables the user to make more accurate judgment.

Embodiments of the present invention include computer readable media including program instructions for performing various computer-implemented operations. This medium records a program for executing the route guidance method described so far. The medium may include program instructions, data files, data structures, etc., alone or in combination. Examples of such media include magnetic media such as a hard disk, a floppy disk and a magnetic tape, optical recording media such as CD and DVD, ROM, RAM, flash memory, and the like, and the like. Examples of program instructions include machine language code such as those produced by a compiler, as well as high-level language code that may be executed by a computer using an interpreter, etc.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention. Accordingly, such modifications or variations are intended to fall within the scope of the appended claims.
