Figure 9 shows the structure of reporting traffic information according to the configuration of the mobile communication terminal 100 and the traffic information management server 200 of the present invention. The mobile communication terminal 100 of the present invention has the same configuration as the mobile communication terminal possessed by the driver of another vehicle on the road as well as the mobile communication terminal possessed by the driver of the reporting vehicle. All mobile communication terminals report traffic information. At the same time, it is possible to receive the traffic information propagated from the traffic information management server 200 at the same time.

The mobile communication terminal 100 of the present invention is a GPS coordinate value from the GPS unit 116 at each time interval set by the control unit 102 by the controller 102 along with the operation of the vehicle as the current value GPS (t0), the previous value The GPS (t-1) is repeatedly measured and stored in the GPS coordinate storage unit 118, and the road name being driven is retrieved from the roadside GPS DB 110 and stored in the traffic information storage unit 108.

Text information including the content of the failure or accident is placed in the traffic information storage unit 108 and transmitted to the traffic information management server 200 through the mobile communication unit 112. In this case, the text information in the text format may be directly input as a text through the mobile communication terminal 100, or a text string of a failure or accident may be selected in a menu form. The designated contact number of the mobile communication terminal 100 as a number set and contacted to contact in case of the above-mentioned failure accident, is a mobile communication of the reporting vehicle separately from the processing institution to which the traffic information is transmitted by the traffic information management server 200 The number of the contact information input to the terminal 100 may be one or more numbers as the number of an agency or other contact number, such as an insurance company designated by the user, a failure accident handling auto service, or the like.

Therefore, the mobile communication terminal 100 of the present invention, when a breakdown or accident occurs while driving, inputs and transmits only the breakdown or the accident contents in a text format to the location of the accident vehicle and GPS (t0) and previous value GPS (t-1). Reporting of traffic information including the direction of travel as a vector value provided is completed. At this time, a still image or a video input through the mobile communication terminal 100 may be added to the reserved field as necessary.

Figure 10 shows the structure of the propagation of traffic information according to the configuration of the mobile communication terminal 100 and the traffic information management server 200 of the present invention.

The server control unit 204 of the traffic information management server 200 receiving the traffic information from the mobile communication terminal 100 described in FIG. 9 through the IP communication unit 202, the service subscriber DB 216 In the case of a valid subscriber by searching, a traffic information ID is given as an identifier to the received traffic information, and the mobile ID, vehicle information, designated contact number of the received traffic information, and time information provided from the time stamp unit 212 are added to the received traffic information. It is stored in the data logger 214 as traffic report information. Subsequently, the server control unit 204 of the traffic information management server 200 is a road name, a GPS coordinate value, where the report vehicle is located, from the received traffic information, the current value GPS (t0), the previous value GPS (t-1), and text characters Extracts information, and searches the road name, current value GPS (t0) and previous value GPS (t-1) from the server-side road GPS DB (208) to refer to the road name where the report vehicle is located, the fault / accident point, and the driving direction. Then, the geo-fence area on the road for providing traffic information is calculated by the GPS coordinates and distance r on the road through the geo-fence calculation unit 210, and the GPS coordinates GPS (g) and distance r on the road corresponding to the resultant values are obtained. It is stored in the radio wave information storage unit 206 as a fence area value. Next, the server control unit 204 of the traffic information management server 200 transmits the information stored in the radio wave information storage unit 206 to the mobile communication network through the IP communication unit 202, the designated contact number included in the traffic information, and the processing institution. It propagates and transmits to other vehicles, including and stores it in the data logger 214 as propagation information. At this time, the geo-fence area is a GPS coordinate and a distance r from the GPS coordinate value GPS (t0) on the road where the report vehicle is located to the furthest point on the road where traffic information is to be propagated. The geo-fence area is calculated as a GPS coordinate value GPS (g) calculated from a GPS value on a corresponding road of the server-side road GPS DB 208 and a distance r to the GPS (g) point, and a server-side road GPS DB The distance r of the geo-fence area may be set separately according to the frequency or safety of the accident for each road and point in 208, and the distance r of the geo-fence area is set to be constant to obtain GPS from the server-side road GPS DB 208. It may be configured to extract the coordinate value GPS (g). In addition, a still image or video provided through the mobile communication terminal 100 of the reporting vehicle may be added to the reserved field, if necessary.

As described above, the mobile communication terminal 100 of the present invention has the same configuration as the mobile communication terminal possessed by the driver of the other vehicle as well as the mobile communication terminal possessed by the driver of the reporting vehicle. Accordingly, the mobile communication terminals of the vehicles that have received the traffic information propagated from the traffic information management server 200 extract the current GPS coordinates, read the GPS coordinates of the corresponding road from the roadside GPS DB 118, and the traffic information. Compared to the road name included in it, it is possible to determine whether vehicles receiving traffic information are driving the corresponding road. In addition, the mobile communication terminals of vehicles that have received the traffic information propagated from the traffic information management server 200 measure the GPS coordinates in which each terminal is located through the GPS unit 114, where each of the current mobile communication terminals is located. From the coordinate P of the point, distances to GPS (t0) and GPS (t-1) included in the traffic information can be converted. From this, the distance d (t0) from P to GPS (t0) is greater than the distance d (t-1) from P to GPS (t-1), and d (t0) and d (t-1) over time. If it decreases, it can be judged as approaching the point of the reporting vehicle. In addition, if the distance r from the GPS coordinate value GPS (g) to GPS (t0) is smaller than d (t0) as the geo-fence area included in the traffic information propagated from the traffic information management server 200, the traffic information management server ( The mobile communication terminals of the vehicles receiving the traffic information propagated from 200 may be determined to be located in the geo-fence area.

As a configuration for determining the geo-fence area using the GPS (g), the control unit 102 of the mobile communication terminals of the vehicles that have received the traffic information propagated from the traffic information management server 200 is a GPS in which each terminal is located. The distance from the coordinate P of the point where each of the current mobile communication terminals is located by measuring the coordinates through the GPS unit 116 to the GPS (t0), GPS (t-1), and GPS (g) included in the traffic information. Is calculated, the distance d (t0) from P to GPS (t0) is greater than the distance d (t-1) from P to GPS (t-1), and d (t0) and d (t-1) over time. ) Is reduced, and if the distance from the GPS coordinate value GPS (g) to GPS (t0) is greater than d (t0) as the geo-fence area included in the traffic information propagated from the traffic information management server 200, It is judged that it is approaching the point, and the received traffic information is displayed on the screen or an alarm sound is provided to the driver.

In addition, as a configuration of determining the geo-fence area using the distance r to the GPS (g) point, the control unit 102 of the mobile communication terminals of the vehicles receiving the traffic information propagated from the traffic information management server 200, By measuring the GPS coordinates where each terminal is located through the GPS unit 116, from the coordinate P of the point where each of the current mobile communication terminals is located, to the GPS (t0) and GPS (t-1) included in the traffic information. Convert the distance, and the distance d (t0) from P to GPS (t0) is greater than the distance d (t-1) from P to GPS (t-1) and d (t0) and d (t- over time) 1) decreases, and when d (t0) is smaller than the distance r from the GPS coordinate value GPS (g) to GPS (t0) as a geo-fence area included in the traffic information propagated from the traffic information management server 200, , The vehicle that received the traffic information is not located on the road at the GPS (t0) point, but is within the valid geo-fence area r. Judging, the received traffic information is displayed on the screen or an alarm sound is provided to the driver. The reason for using such a valid geo-fence area r is that it is effective when a vehicle entering from a path of another road name receives propagated traffic information when there are branch points in the road section from GPS (g) to GPS (t0). It is to judge and provide.

The display of the traffic information may be such that the mobile communication terminal 100 is connected to a navigation device through a wireless or cable, such as a local area communication channel, and displayed on a map.

FIG. 11 shows a structure for reporting traffic release according to the configuration of the mobile communication terminal 100 and the traffic information management server 200 of the present invention.

The mobile communication terminal 100 of the present invention described with reference to FIG. 9 in the preceding figure, receives the GPS coordinate values from the GPS unit 116 at every time interval set by the control unit 102 to the timer 104 even after reporting a failure or accident. It is measured repeatedly and stored in the GPS coordinate storage unit 118. If the GPS coordinate values measured repeatedly as described above are measured with a GPS coordinate value GPS (t0) different from the GPS coordinate value of the point where a failure or accident is reported, the control unit 102 of the mobile communication terminal 100 displays a GPS unit ( From 114), the values of GPS (n + 1), GPS (n + 2), GPS (n + 3), ..., which are repeatedly measured from the previous value GPS (n0), are measured at set time intervals and driving speed Through the operation unit 106, GPS (n + 1), GPS (n + 2), GPS (n + 3), ... which are measured repeatedly from GPS (n0), calculate the section speed for each section. When the calculated section speed is greater than or equal to the set speed, the control unit 102 of the mobile communication terminal 100, GPS (n + 1), GPS (n + 2), GPS (n) as the GPS coordinate value from the GPS unit 116 +3), ... are repeatedly measured and stored in the GPS coordinate storage unit 118, the mobile ID and vehicle information from the user information storage unit 120 of the mobile communication terminal 100, and a designation designated by the user Number of contact information, road name stored in traffic information storage unit 108, GPS coordinate value stored in GPS coordinate storage unit 118, previous value GPS (n0) and current value GPS (n + 1), driving speed calculation unit 106 Section speeds above a certain speed calculated through are arranged in the traffic information storage unit 108 and transmitted to the traffic information management server 200 through the mobile communication unit 112.

The above-mentioned release notification information indicates that the mobile communication terminal 100 of the reporting vehicle has moved out of the reporting point by moving at a certain speed (for example, 20 to 30 km / h) or more, and the traffic information management server 200 reports a failure or failure. It can be judged that the accident has been lifted. In addition, the above release report information is a structure compatible with the structure of the traffic information described in FIG. 9 of the previous drawing, while the text information field of the traffic information is input in a text format (for example, ASCII code), while the corresponding release information is released. The section speed field of the report information can also be classified with a numeric code.

Therefore, the traffic information processing system using the linear vector geo-fence data of the present invention has a feature of providing the traffic information management server 200 from the mobile communication terminal 100 without any manipulation to release the failure or accident.

FIG. 12 shows a structure for disseminating and distributing traffic information according to the configuration of the mobile communication terminal 100 and the traffic information management server 200 of the present invention. The server control unit 204 of the traffic information management server 200 receiving the traffic information release information from the mobile communication terminal 100 through the IP communication unit 202 transmits the traffic information release information from the data logger 214. The radio wave information of the traffic information ID including one mobile ID is extracted, and the text information portion of the radio wave information is changed to release information and stored in the data logger 214 and the radio wave information storage unit 206 as release information. Next, the server control unit 204 of the traffic information management server 200 includes the information stored in the radio wave information storage unit 206 and the designated contact number included in the traffic information to the mobile communication network through the IP communication unit 202 and a processing institution. To propagate and transmit to other vehicles. At this time, the other information portion of the release information propagates the release information to the vehicle that previously received the traffic information as the propagation information by maintaining the value of the propagation information.
