In general, traffic lights installed for pedestrians in pedestrian crossings consist of green pedestrian lights and red stop lights, and each traffic light is alternately lit under the control of the traffic light operating system.

Currently, pedestrians are protected from accidents by allowing the pedestrian lights to flash before the pedestrian lights turn into stop lights so that pedestrians can recognize them when the pedestrian lights turn into stop lights. However, even if the walking light is blinking, since the exact remaining time is not known, pedestrians often cross the road excessively, and thus there is a problem such as a traffic accident.

Recently, in order to solve this problem, a method of numerically displaying the remaining time of walking lights has been adopted. However, in the case of pedestrians, such as the elderly, children, visually impaired, it is difficult to check the remaining time, such as walking, there is a problem that there is a lot of inconvenience and psychological pain when crossing.

The present invention has been made to solve the above-described problems, when the mobile communication terminal holder approaches the crosswalk automatically provides traffic light information, or when the mobile communication terminal holder reaches the crosswalk and requests the traffic light information There is a technical problem to provide pedestrians to safely cross the road by providing traffic light information of the crosswalk to the mobile communication terminal.

The same as the remaining lights off time), the place name and the direction (for example, *** crossroad ++ direction), and the like where the traffic lights are installed.

In the traffic information providing system 100 having such a configuration, the traffic light information collecting unit 150 collects traffic light installation location information in the form of latitude / longitude coordinates and stores the data in the data storage 130. The location collection / checking unit 140 receives location information of the mobile communication terminal in the form of latitude / longitude coordinates from the location tracking center 50. In addition, the mobile communication terminal location collecting / confirming unit 140 checks whether the location coordinates of the mobile communication terminal are within a specified range from the latitude / longitude coordinates of the traffic light with reference to the data storage unit 130, and the mobile communication terminal transmits the traffic. When it is determined that the traffic light is adjacent to the installation position, the control unit 110 causes the traffic light information collecting unit 150 to request the state of the traffic light to the traffic light operating system 20 and receive a response thereto. Accordingly, the traffic information generation unit 160 generates traffic information in a text and / or voice form by using the traffic light state received from the traffic information collecting unit 150, and the mobile communication system through the communication network interface 120. The traffic information is transmitted to the 30 so that the traffic information is transmitted to the corresponding mobile communication terminal.

In addition, the traffic information providing system 100 of the present invention may further include a mobile communication terminal monitoring unit 170.

To send).

The mobile communication terminal location collection / receiving unit 140 receiving the location information of the mobile communication terminal checks whether there is a traffic light installed in an adjacent area of latitude / longitude coordinates of the mobile communication terminal (S107), In this case, the traffic light identification number is extracted with reference to the data storage unit 130 (S109). In addition, the traffic light identification number is transmitted to the traffic light operating system 20 to request lighting information of the corresponding traffic light (S111), and the response to the response from the traffic light operating system 20, that is, the current lighting state and the remaining light off time. And the like (S113).

When receiving the lighting information of the traffic light from the traffic light operating system 20, the traffic information generation unit 160 generates the traffic information using this (S115). The traffic information may be generated by any one of voice, text, video, image, or a combination thereof, and may include installation place names and direction information of the corresponding traffic lights stored in the data storage unit 130. In addition, when the mobile communication terminal is located in an area where two or more traffic lights are installed, traffic information is generated for each traffic light.

Thereafter, the generated traffic information is transmitted to the mobile communication system 30 along with the corresponding mobile communication terminal number through the communication network interface 120, and the mobile communication system 30 transmits it to the mobile communication terminal (S117, S119). . If the traffic information generated in step S115 is two or more, the traffic information may be transmitted in one message or in separate messages.

In this way, the mobile communication terminal user who has received the traffic information can check the state of the traffic light installed in the adjacent crosswalk and cross the road safely.

On the other hand, when the user of the mobile communication terminal that crosses the road by receiving the traffic information may be a visually impaired or the like may deviate from the crosswalk, for this purpose, the following process may be further performed. That is, after transmitting the traffic information to the mobile communication terminal, the location tracking center 50 tracks the location of the mobile communication terminal (S121) and transmits it to the mobile communication terminal monitoring unit 170 of the traffic information providing system 100. (S123). The mobile communication terminal monitoring unit 170 checks whether the corresponding mobile communication terminal deviated from the crosswalk by referring to the latitude / longitude coordinates of the mobile communication terminal received from the location tracking center 50 (S125). If it is determined that the crosswalk has deviated, a message for notifying this is created and the mobile communication terminal is notified that the crosswalk has been deviated through the mobile communication system (S127, S129).

In the above, the GPS receiver is installed in the mobile communication terminal, and after the location information of the mobile communication terminal is tracked, when the traffic light is present in the adjacent position of the mobile communication terminal, the state information of the traffic light is described. . For this embodiment, the mobile communication terminal should be equipped with a GPS receiver.
