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 light at the intersection of the three-way or the intersection, and the sudden change of the straight ahead signal into the yellow or red signal near the intersection, the vehicle must be stopped at the stop line. However, It is passing through an intersection. At this time, a vehicle that receives a left-turn signal in another lane and enters an intersection frequently ignites a signal and collides with a fast-moving vehicle. As such, casualty accidents are increasing every year due to traffic violations and speeding accidents at intersections.

In order to solve such a problem, the following prior art has been disclosed.

First, an apparatus and method for preventing vehicle collision at an intersection based on a sensor network disclosed in Korean Patent Registration No. 10-0626658 (registered on September 14, 2006) (hereinafter, referred to as "Prior Art 1" Real-time speed and position information of the vehicle are obtained through wireless communication of the vehicle, and the obtained information is informed to the vehicle entering the intersection in the other direction through the sensor network in advance to prevent the vehicle from colliding at the intersection.

However, in the prior art 1, the smart sensor nodes are installed in the vicinity of the intersection, the vehicle information providing means and the vehicle information analyzing means must be provided in the vehicle, and a network environment must be established between the sensor nodes. There is a problem that installation and operation costs are large.

The signal control device and its control method (hereinafter referred to as "Prior Art 2") of the three-way intersection disclosed in Korean Patent Registration No. 10-1114968 (registered on Mar. 23, 2012) If the speed of the vehicle falls to the intersection passing dilemma, the current straight-ahead signal is maintained for a certain period of time to prevent the vehicle from colliding at the intersection.

However, in the prior art 2, when the left turn display is omitted or terminated early depending on the presence or absence of the left turn vehicle and the number of waiting vehicles, if the straight turn signal is maintained for a certain time according to the vehicle speed, The signal delay or the shortening of the signal of the pedestrian of the mobile communication terminal of the mobile communication terminal is increased.

Therefore, there is an urgent need to develop an intersection traffic accident prevention system that is simple in configuration and effective without confusing the existing traffic light system.

First Embodiment of Intersection Traffic Accident Prevention System

1 to 4 are views showing an intersection traffic accident prevention system according to a first preferred embodiment of the present invention. FIG. 1 is an exemplary view showing an example of applying the system of the present invention to an intersection, and FIGS. 2 and 3 Fig. 4 is a block diagram of the first embodiment. Fig.

1 to 4, the vehicle traffic light 110, the video camera 120, the beacon light 130, the electric sign board 140, the speaker 150 ), A sound detection sensor 160, and a controller 200.

The intersection accident prevention system of the present invention having the above-described configuration can be applied to an intersection as shown in FIG. Here, the roads (1 to 4) are connected to the intersections, and the traffic lights (101 to 104) may be arranged on the roads (1 to 4) entering or exiting the intersection. At this time, although the traffic lights 101 to 104 are each configured to be on both roads (① to ④) of the intersection, the traffic lights 101 to 104 may be disposed only at one place in the direction of entry or advance of the intersection.

The traffic lights 101 to 104 may be disposed on the respective roads (1 to 4) connected to the intersection. The signal lamps 101 to 104 may include a vehicle signal lamp 110, a video camera 120, a warning light 130, an electric sign board 140, a speaker 150, and a sound detection sensor 160.

The vehicle signal lamp 110 includes red, orange, left or right, green (straight) signals, and includes lamp signals, LED signals, and the like.

The image camera 120 may be installed in the traffic lights 101 to 104 or may be installed on the left and right sides of the intersection roadway in addition to the traffic lights 101 to 104. [ The intersection may be composed of intersections such as three-way, five-way, six-way, and the like.

The video camera 120 captures an image of a vehicle approaching an intersection on each road, and senses the speed and motion of the vehicle. Also, the image camera 120 may be configured to detect not only the speed of the vehicle but also the distance through the image.

Meanwhile, the speed and the distance of the vehicle may be configured to detect the speed and distance of the vehicle from the image data of the image camera 120 in the controller 200. At this time, the control unit 200 may calculate the arrival time from the speed and distance of the sensed vehicle to the intersection, and predict a traffic accident caused by signal violation and overspeed at the intersection.

When the vehicle signal lamp 110 at the intersection is changed from the straight ahead or left turn signal to the orange or red signal, the image camera 120 detects the vehicle of the changed road, The vehicle and the vehicle running at a predetermined speed or more within a predetermined distance from the intersection for a predetermined period of time are ignored and the straight ahead and left-handed vehicle (s) entering the intersection are sensed.

The vehicle signal lamp 110 is turned from the straight ahead or left turn signal to the orange or red signal by the image camera 120 to make a straight line or a left turn that rushes over the predetermined speed toward the intersection or ignores the signal and enters the intersection When the vehicle is detected, the control unit 200 activates the beacon light 130 disposed in the traffic lights of the respective traffic lights and outputs a caution character through the electric billboard 140.

In addition, the image camera 120 identifies a warning light of an emergency automobile including a fire truck, a 119 ambulance, and a police car through the image, and detects the dispatch of the emergency automobile.

In this case, the method of detecting the emergency vehicle dispatching operation identifies a warning light of the emergency vehicle through the image of the video camera 120 and identifies the siren sound of the emergency car through the sound detection sensor 160, It will detect the dispatch. That is, when both the warning light of the emergency vehicle and the siren sound are recognized through the video camera 120 and the sound detection sensor 160, the emer- gency of the emergency car is detected.

The image camera 120 may include a digital camera, a digital zoom camera, a thermal imager, and an infrared camera.

The beacon light 130 may be disposed in the traffic lights 101 to 108. The beacon light 130 ignores the signal of the intersection on the road where the vehicle signal lamp 110 changes from the straight ahead or left turn signal to the orange or red signal and ignores the vehicle and the signal running at more than a predetermined speed toward the intersection, It will be activated automatically when the incoming straight ahead and left-handed vehicles are detected or emergency vehicles are detected. At this time, the warning light 130 is a special warning light for warning of red, green, and yellow, and may include a red warning light.

The electric sign board 140 may be operated with the operation of the beacon light 130 or the auxiliary traffic light (refer to 180 in FIG. 8) disposed in the traffic light of each traffic lane when the emergency vehicle including the fire truck, 119 ambulance, And outputs a character. At this time, the caution character is "Caution! Emergency car dispatch "" Emergency car dispatch now. Please give up "and so on.

In addition, the electric sign board 140 is configured to display the speed of the vehicle sensed through the video camera of each driveway in real time when the vehicle running at an overspeed ignoring the signal or the dispatch of the emergency car is not detected . At this time, when the speed of the vehicle exceeds the limit speed, the number of the vehicle speed or the screen of the electric sign board may be periodically blinked, so that the driver of the vehicle can be configured to call attention.

The speaker 150 may be disposed in the signal lamps 101 to 104. The loudspeaker 150 may be a straight line or a left-turn vehicle in which the vehicle signal lamp 110 at the intersection is ignored in a traffic light changed from a straight ahead or left turn signal to an orange or red traffic signal and rushes over a predetermined speed toward an intersection or enters an intersection. It can be configured to automatically generate a siren or alarm sound. However, the speaker 150 may be configured not to generate a siren or an alarm sound due to a problem of noise depending on the place where the signal lamp is installed.

The sound detection sensor 160 detects a siren sound of an emergency car including a fire truck, a 119 ambulance, and a police car, and senses the dispatch of the emergency car. As described above, the method of detecting the emergency vehicle dispatching operation identifies the emergency light of the emergency vehicle through the image of the video camera 120 and identifies the siren sound of the emergency car through the sound detection sensor 160 Thereby detecting the dispatch of the emergency car. That is, when both the warning light of the emergency vehicle and the siren sound are recognized through the video camera 120 and the sound detection sensor 160, the emer- gency of the emergency car is detected.

The sound detection sensor 160 may be installed in the signal lamps 101 to 108 together with the image camera 120 and may be installed in a control box (not shown) installed together with the signal lamps 101 to 104 It is possible.

The control unit 200 detects the speed and movement of the vehicle on the road where the vehicle signal lamp 110 at the intersection is changed from the straight ahead or left turn signal to the orange or red signal by the video camera 120, When a violating vehicle is detected by detecting straight ahead and left-turn vehicles entering the intersection while ignoring vehicles and signals that run at a predetermined speed or more within a predetermined distance in an intersection for a period of time, And controls the warning light 130 or an auxiliary signal lamp 180 (see FIG. 8) to operate and to output a caution character through the electric sign board 140.

The controller 200 controls the vehicle signal lamp 110 at the intersection so that the vehicle signal lamp 110 is turned on or off when the vehicle signal lamp 110 is turned from the straight ahead or left turn signal to the orange or red signal, The siren or alarm sound is automatically generated through the speaker 150 disposed in the traffic lights 101 to 104 of the respective roads.

The control unit 200 detects the warning light of the emergency vehicle including the fire truck, the 119 ambulance and the police car and the sound of the siren through the video camera 120 and the sound detection sensor 160, When the automobile is activated, the warning lamp 130 or the auxiliary signal lamp 180 (see FIG. 8) disposed in the traffic lights 101 to 104 of the respective traffic lights is operated and the control characters are output through the electric signboard 140 .

The control unit 200 controls the speed of the vehicle sensed through the video camera 120 of each driveway to be greater than the speed of the vehicle when the vehicle is running at overspeed, (140), and controls the number of vehicle speed or the screen of the electric sign board (140) to be flickered periodically when the speed of the vehicle exceeds the limit speed.
