Today, at intersections, traffic accidents frequently occur when vehicles attempting to pass through an intersection without being able to find a vehicle entering from another direction are colliding with other vehicles. Particularly, when the driver watches the straight ahead signal of the vehicle signal at the intersection of three-way or intersection, he / she must run at speed and stop the vehicle at the stop line when the signal immediately before the intersection turns yellow. However, most vehicles pass the intersection at high speed . At this time, a vehicle that receives a left-turn signal from another lane and enters the intersection ignores the signal, causing a collision with a vehicle that goes straight ahead. In this way, traffic accidents caused by traffic violation vehicles at intersections are increasing the number of accidents every year. However, there is no clear method to solve them.

In order to clearly explain the present invention in the drawings, parts not related to the description are omitted, and like parts are denoted by similar reference numerals throughout the description of the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

First Embodiment of Intersection Signal Violation Traffic Accident Prevention System

FIG. 1 is a perspective view of a traffic accident accident prevention system for an intersection signal according to a first preferred embodiment of the present invention, and FIG. 2 is a plan view of FIG.

1 and 2, the first embodiment of the intersection signal violation traffic accident prevention system according to the present invention includes a speed detection camera 30, a vehicle signal lamp 40, a control unit (not shown, refer to 90 in FIG. 4 ). ≪ / RTI >

The speed sensing camera 30 is installed in a traffic light installed in each of the roads 11 to 14 entering the intersection 50 to detect the speed of the vehicle entering the intersection 50. At this time, although the intersection 50 shows the intersection intersection in FIG. 1 and FIG. 2, the intersection 50 may be formed of intersections such as three-way, short distance, and six-way street.

The speed sensing camera 30 operates when the vehicle signal lamp 40 is changed to a red or yellow traffic light to detect the speed of the vehicle entering the intersection 50. At this time, the speed sensing camera 30 may be configured to detect the speed of the vehicle when the vehicle enters a predetermined distance from the stop line 23 of the intersection 50. At this time, the predetermined distance away from the stop line 23 may be the braking distance a of the vehicle. That is, the speed sensing camera 30 senses the speed of the vehicle entering the braking distance a of the vehicle at the stop line 23 of each driveway entering the intersection 50. In this case, the braking distance (a) refers to the distance traveled from the start of the braking operation until the braking operation is completely stopped.

For example, assuming that the braking distance to the stop line 23 of the intersection 50 is 15 m when the speed of the vehicle is 60 km, the speed sensing camera 30 is positioned at the stop line 23 of the intersection 50, Lt; RTI ID = 0.0 > 15m < / RTI >

The signal lamp provided at the intersection 50 serves to control the vehicle signal lamps 40 of the respective vehicles 11 to 14 entering the intersection 50. The signal lamp of the intersection 50 includes a signal lamp 41 vertically installed around the intersection 50, a signal lamp supporter 42 horizontally installed on the signal lamp supporter 41, And a vehicle signal lamp 40 installed horizontally.

The vehicle signal lamp 40 may include a red traffic light, a yellow traffic light, a green traffic light, and a left turn traffic light.

The control unit (not shown in FIG. 4, 90) controls the intersection 50 so that the vehicle signal lamp 40, which is waiting for a signal at the intersection 50, changes from the red traffic light to the straight ahead or left- Or the left turn signal light is first switched to the orange or red traffic light. This is because the vehicle entering the intersection 50 after receiving the straight ahead or left turn signal is turned into the yellow traffic light before entering the intersection 50 but ignores it and enters the intersection 50 as it is, 50 in order to avoid collision with the vehicle.

The control unit determines whether the vehicle on the road where the orange or red traffic light has changed to the stop line 23 of the intersection 50 is entering the braking distance or more based on the signal of the speed detection camera 30. At this time, when the vehicle is entering the intersection 50 at a braking distance or more, the vehicle signal lamp 40 waiting for the straight ahead or left turn signal light is maintained or delayed by the red signal light for a predetermined period of time, . At this time, the time during which the red traffic light is maintained or delayed can be set to the time when the vehicle passing through the intersection 50 is approaching the intersection 50 at the speed exceeding the braking distance.

For example, if it takes 2 to 4 seconds for a vehicle entering the intersection 50 to pass through the intersection 50 at a speed higher than the braking distance, the vehicle signal lamp 40 waiting for the traffic light at the intersection in another roadway, May be controlled to be converted into a straight ahead or left turn signal after holding or delaying the red traffic light for 2 to 4 seconds or more.

Meanwhile, the control unit may control the speed of the vehicle running toward the intersection 50 in a state where the vehicle signal lamp 40 of the intersection 50 is turned to the orange or red traffic light, It can also be set. At this time, if the controller detects the speed of the vehicle through the speed sensing camera 30 and then rushes toward the intersection 50 at a speed higher than the speed limit, the control unit stops the vehicle signal lamp 40 waiting for the signal on the other road for a predetermined time It can be controlled so that the next traffic light is converted after it is maintained or delayed by the red traffic light.

Therefore, the intersection signal violation traffic accident prevention system according to the first embodiment of the present invention judges whether there is a vehicle entering the intersection from the other roadway at a speed equal to or higher than the braking distance before the vehicle signal light of the intersection changes to the straight ahead or left turn signal light A traffic signal can be prevented from occurring at the intersection by a traffic violation vehicle by maintaining or delaying a red traffic light for a predetermined period of time and then changing to a straight ahead or left turn signal light.

The electric sign board 60 may be horizontally installed on the signal lamp supporter 42 together with the vehicle signal lamp 40 and may be constituted by an LED panel. When the vehicle is running at a speed higher than the braking distance or at a speed exceeding the braking distance toward the intersection, the electric sign board 60 is turned to a red or yellow traffic light. If the next traffic light turns into a straight ahead or left turn signal, Stop "and the like.

In addition, the electric signboard 60 plays a role of preventing overspeed by displaying the speed of the vehicle running on the road on which the electric signboard 60 is installed in real time after the vehicle signal lamp 40 changes the straight ahead or left turn signal light.

In addition, when the crosswalk 24 is provided at the intersection 50, the electric signboard 60 outputs a cautionary character during a pedestrian crossing from a green traffic light (not shown).

The controller 90 controls the vehicle 50 such that the vehicle signal lamp 40 on the roadway waiting for the signal at the intersection 50 switches from the red traffic light to the straight ahead or left turn signal light, So that the traffic light 40 is first switched to an orange or red traffic light. Based on the signal from the speed sensing camera 30, it is determined whether the vehicle with the orange or red traffic light has entered the stop line 23 of the intersection 50 at a speed equal to or higher than the braking distance And controls the vehicle signal lamp 40, which is the next signal lamp to be changed to a straight ahead or left turn signal lamp, to maintain or delay the vehicle signal lamp 40 for a predetermined time with a red light or the like, and then to convert it to a straight ahead or left turn signal light when the vehicle is entering the intersection at an overspeed.

In addition, when the vehicle is running at a speed higher than the braking distance or at a speed higher than the braking distance, the control unit 90 instructs the vehicle on the road where the next traffic light changes to a straight ahead or left turn signal light. Through the electric signboard 60, "Danger! Stop " or the like. In addition, the vehicle signal lamp 40 controls the display of the speed of the vehicle running on the road on which the electric sign board 60 is installed to be displayed on the electric sign board 60 in real time after the straight ahead or left turn signal lamp is changed.

When the crosswalk 24 is provided at the intersection 50, the control unit 90 displays a cautionary character during a pedestrian traffic light (not shown) during a pedestrian crossing through the electric signboard 60 from a green traffic light .

Therefore, in the intersection signal-violation traffic accident prevention system according to the second embodiment of the present invention, when the vehicle is running at a speed higher than the braking distance or at a speed limit or more than the braking distance toward the intersection in the traffic light changed to the red or yellow traffic light, (60) to the vehicle on the road that changes to a straight ahead or left turn signal light. Quot; stop " or the like, the traffic accident caused by the vehicle with a signal violation at the intersection can be prevented in advance.
