Hereinafter, a traffic safety information providing method according to an embodiment of the present invention will be described in more detail with reference to FIG. 6 and FIG.

6 is a view for explaining a first embodiment of the present invention. In this case, traffic safety information is provided when the traffic safety information providing system includes the cloud platform 100 and the user terminal 200, FIG. 3 is a diagram for explaining a second embodiment of the present invention, which provides traffic safety information when the traffic safety information providing system further includes the road facilities 300 and the surrounding vehicles 400.

6 is a flowchart illustrating a traffic safety information providing method according to a first embodiment of the present invention.

As shown in FIG. 6, in the method of providing traffic safety information according to the first embodiment, steps S610 to S660 refer to a step in which the cloud platform determines whether the user is in a dangerous situation during walking or driving. In step S670 Steps S700 through S700 refer to a step in which the cloud platform collects incident-related data when an accident occurs to the pedestrian and the driver. For the convenience of explanation, it is divided into two steps.

First, the user terminal 200a installed in the vehicle detects movement information of the vehicle (S610). Here, the movement information of the vehicle includes at least one of a position, a speed, a moving direction, and an engine speed (rpm) of the vehicle, and may further include a braking distance, a princess distance, and a stop distance of the vehicle.

The user terminal 200a can detect the position of the vehicle using a GPS (Global Positioning System), and use the moving speed information of the vehicle sensed by the vehicle speed meter as movement information of the vehicle.

The user terminal 200a installed in the vehicle transmits the detected movement information of the vehicle to the cloud platform 100 (S615). At this time, the user terminal 200a transmits the movement information to the cloud platform 100 using Zigbee, Bluetooth, NFC, or other remote communication such as 3G, 4G, LTE or LTE-A Lt; / RTI >

Next, the pedestrian user terminal 200b also senses the movement information of the pedestrian (S620) and transmits it to the cloud platform 100 (S625). The pedestrian user terminal 200b senses the position of a pedestrian using a GPS (Global Positioning System), detects movement information of a pedestrian's walking speed and walking direction information, and transmits the sensed information to the cloud platform 100. The process of transmitting the movement information sensed by the pedestrian user terminal 200b to the cloud platform 100 includes the steps of transmitting the movement information of the vehicle to the cloud platform 100 by the user terminal 200a installed in the vehicle in step S615 Duplicate explanations are omitted.

For convenience of explanation, the user terminals 200a and 200b have been described as transmitting the movement information including the moving speed of the vehicle or the pedestrian to the cloud platform 100. However, the present invention is not limited thereto, The speed of the vehicle or the pedestrian can be predicted using the positional information of the vehicle or the pedestrian periodically received from the vehicle or the pedestrian.

Next, the cloud platform 100 determines whether it is a dangerous situation (S630). The cloud platform 100 predicts collision between the vehicle and the pedestrian using the movement information of the vehicle received from the user terminal 200a installed in the vehicle and the movement information of the pedestrian received from the pedestrian user terminal 200b. The cloud platform 100 judges that the vehicle and the pedestrian are in a dangerous situation. In addition, the cloud platform 100 estimates the probability of occurrence of an accident using the movement information, and can determine that a case where the probability of occurrence of an accident is equal to or greater than a threshold value is a dangerous situation.

Here, if the cloud platform 100 is expected to arrive at the same position at the same time as a result of anticipating the travel route based on the travel information of the vehicle and the pedestrian, the collision between the vehicle and the pedestrian may occur. In addition, the cloud platform 100 may determine that the position of the vehicle and the pedestrian is estimated to be below the threshold value at the same time, as a dangerous situation.

Also, the cloud platform 100 may calculate a time to collision (TTC) or a frontal offset (FO) using the received movement information, and predict a dangerous situation through the calculated result value .

Here, the collision time (TTC, Time to Collision) is calculated by using the relative speed with the preceding vehicle or pedestrian, and the relative distance between the preceding vehicle or the pedestrian is divided by the relative speed with the preceding vehicle or pedestrian Can be calculated.

The collision between the colliding object and the vehicle or the pedestrian can be determined using the front collision offset (FO, Frontal Offset). Even if the calculated collision time (TTC) value is within the range where the collision occurs, the actual collision may not occur when the front collision offset amount FO is zero.

For convenience of explanation, it is described that the collision between the vehicle and the pedestrian is judged to be a dangerous situation. However, the present invention is not limited to this, and it is possible to predict whether a collision with a vehicle or a collision with a pedestrian is possible.

If it is determined that there is a dangerous situation, the cloud platform 100 generates and transmits a danger warning message to the user terminals 200a and 200b in the dangerous state (S640). At this time, the risk warning message may include the time and place where the risk is expected to occur, the kind of the risk to be predicted, and the like. In step S615 and step S625, the cloud platform 100 can transmit a danger warning message generated in the user terminals 200a and 200b using the communication method when the mobile terminal 200a or 200b receives the movement information from the user terminal 200a or 200b have.

Then, the user terminals 200a and 200b output the received danger warning message (S650). The user terminals 200a and 200b may output a danger warning message to warn the driver or the pedestrian that a dangerous situation may occur. Here, the dangerous situation may be a collision with a pedestrian or a collision with another vehicle.

The user terminals 200a and 200b may output a danger warning message using at least one of a warning sound, a lamp, an image, and a voice. You can blink the lamp in the direction that a hazard is expected to occur, or output a warning sound. Also, the user terminals 200a and 200b may warn the user of the danger by using the voice guidance, or may output the time, position or direction predicted to cause the danger, and the type of the danger and the type of the danger.

In addition, the cloud platform 100 determines whether an accident has occurred between the user terminals 200a and 200b using the movement information periodically received (S660). The cloud platform 100 can determine whether an accident has occurred by using the amount of change of the movement information received from the user terminals 200a and 200b predicted to cause a risk.

The cloud platform 100 determines whether or not a risk is expected to occur by using the collision time (TTC, time to collision) or the frontal offset (FO) calculated in step S630, And the change amount of the position of the user terminals 200a and 200b. If the movement of the corresponding user terminal 200a or 200b is not detected, the cloud platform 100 determines that an accident has occurred.

If it is determined that an accident has occurred, the cloud platform 100 collects incident-related data through steps S670 to S700. For convenience of explanation, it is assumed that an accident has occurred by using the movement information, and it is assumed that the user terminal 200a installed on the vehicle and the user terminal 200b for a pedestrian collide with each other.

In this case, the cloud platform 100 transmits a data request message to the user terminal 200a and the pedestrian user terminal 200b installed in the vehicle, which is a user terminal related to the accident (S670).

Here, the data request message includes a position determined as an accident, and may include at least one of a time interval of requested sound or image data, a number of frames, a frame speed, and an image format. At this time, the time interval of the requested sound or image data is set on the basis of the time at which it is determined that an accident has occurred.

The user terminal 200a installed in the vehicle receiving the data request message collects sound or image data in step S680 and transmits the sound or image data to the cloud platform 100 in step S685. The user terminal 200a installed in the vehicle can transmit sound or image data recorded or recorded by a black box or navigation to the cloud platform 100. [ At this time, the user terminal 200a installed in the vehicle can transmit sound or image data using the communication method used when the mobile information is transmitted to the cloud platform 100 in step S615.

Also, the pedestrian user terminal 200b that has received the data request message also collects sound or image data (S690) and transmits it to the cloud platform 100 (S695). The sound or image data is recorded using the recording function of the pedestrian user terminal 200b and sound or image data recorded using the photographing function in step S625 by using the communication method used when the mobile information is transmitted to the cloud platform 100 Lt; / RTI >

The cloud platform 100 stores the received sound or image data (S700). Sound or image data received from a plurality of user terminals 200a, 200b associated with an accident can be used for integrated analysis and determination of accidents that have occurred.
