Conventionally, a traffic information collection provider collects and provides traffic information using a probe car having a GPS, beacon, etc. device, but in the present invention, general users who use the service generate traffic information. Take the way to share. That is, in the case of the first user 610, road information stored in the user DB (in the case of a new road, road information may not exist in the user DB) or when the signaling system is different from the actual one (611) After storing, the data can be sent later in a batch or reported to the server in real time (612). The new information (e.g., new road information, signaling system information, etc.) is transmitted to the location information management server (640) and synchronized between the server and the client terminal to share information (613). In the case of the second user 620 and the third user 630, the user agent determines that the speed is significantly slower than the existing stored / analyzed information or that the vehicle is congested, construction, accident, crackdown, etc. with the help of the user. If stored in the user DB and later reported to the server in a batch transfer or in real time (622), the traffic information is synchronized between the server and the user can be shared (623).

The server integrates / analyzes the user's road information (movement trajectory) or traffic information to generate a map, change the signal system, or generate traffic information in the case of a new road (640), and the user who needs it again Information sharing through synchronization with the user (613, 623).

7 is a flowchart illustrating a process of collecting and reporting a traffic information service during a service providing process of a user-generated location-based service system according to the present invention. First, the client is executed in the user terminal, and if membership is performed, member authentication is performed, and if not, the member is registered (S710). If the privacy default setting is the first time or if you want to change the setting of the range and policy of the information to be transmitted to the server is switched to the location information collection mode (S720). As the user moves, location information is collected (S730), and whether the difference is more than a predetermined value from the speed analyzed and stored in the existing user DB (S740), and if there is a difference, the speed information is reported to the server. (S750). In addition, when the user is passing a new road that does not exist in the stored map (S760), the user's movement trajectory is stored in the user DB by using the mobile DB manager (S770), and the data storage is terminated (S780), later The server transmits the data to the server at once (S790).

8 is a flowchart illustrating a process of using a traffic information service during a service providing process of the user-generated location-based service system. The use step may be performed in parallel with the process of the collection step described in FIG. 7. In order to use the service, the user first goes through a process of membership authentication or membership (S810), and then sets a starting point and a destination to perform navigation (S820). The user agent receives the changed part by synchronizing map information and traffic information necessary for routing from the server and performs routing (S830). The user is guided (S840) and terminates upon arrival according to whether or not the destination has been reached (S850), and dynamically performs a routing using the synchronization of the map / traffic information in real time, if necessary, in operation S860.
