Description

Intelligent vehicle traffic signal control system

The present invention relates to an intelligent vehicle intersection signal control system, and more particularly, a vehicle recognition sensor and a photographing means are installed in one direction and the other direction of a road construction section, and a passing vehicle is confirmed through the vehicle recognition sensor, and a photographing means By counting the number of vehicle objects approaching through the vehicle and generating a vehicle crossing signal according to the traffic congestion calculation, it is a technology that reduces the human/material cost required to install equipment for vehicle recognition without a worker for traffic control.

For road construction, at least one or more lanes are blocked. At this time, the subject of the road construction installs guide facilities to induce the safety of vehicle traffic and smooth traffic flow.

However, since the risk of traffic accidents is high by installing guide facilities alone, traffic flow is controlled through hand signals from workers in addition to installing guide facilities at most road construction sites.

In particular, in the case of road construction on two round-trip lanes, one lane is closed and the vehicle flow is controlled through the other lane.At this time, the driver relies on radio communication and hand signals between workers located on one side and the other side of the lane closure. There is no choice but to pass through the construction section.

Therefore, the driver only stops according to the operator's hand signal without prior information on the flow of the vehicle, the amount of movement, the degree of congestion, and the waiting time, and then passes through the road construction section, resulting in dissatisfaction with the vehicle stop and distrust of the road construction. There is a problem.

In addition, in the case of a road construction site, a lot of labor costs are required to arrange a worker for traffic control until the construction is completed. In particular, in the case of a road construction performed at night, there is a problem that it is difficult to identify the worker, thereby increasing the risk of a traffic accident.

As a document for solving this problem, Korean Patent Registration No. 10-1147447 (Road Construction Traffic Management System and Method (2012.05.11. Registration)) is installed at regular intervals in front of the road construction section to determine the presence or absence of vehicles. It constitutes a plurality of vehicle detection means with a sensor that detects the speed, and transmits a message signal to the message display means installed in the front of the road construction section by determining the road condition of the road construction section according to the detection result of the sensor. A configuration for a mobile signal device for providing a driving or stop signal to a vehicle passing through a construction section is disclosed.

However, in the case of the prior patent, it is necessary to install a vehicle detection means composed of a plurality of sensors in one direction and the other direction of the road construction section, and thus there is a problem that a lot of cost and time is required to install the vehicle detection means.

In addition, the prior patent is configured to control the output of a driving or stop signal of a vehicle in consideration of only fixed conditions such as distance and speed of the vehicle passing through the road construction section. Accordingly, there is a problem in that traffic flow in a road construction section is hindered by only operating according to a predetermined pattern without consideration of a time period or an unexpected situation (ambulance, fire engine) when traffic flow is congested or traffic is high.

Hereinafter, a method of controlling an intelligent vehicle crossover signal according to an embodiment of the present invention will be described with reference to FIG. 9.

First, the photographing means photographs an image while aiming at one direction or the other direction of the road construction section (S702).

Subsequently, the object detection means recognizes the vehicle object from the image approved by the photographing means, and counts the number of vehicle objects recognized during the set time (S704).

Then, the intersection signal control means generates a vehicle intersection signal for controlling the lighting of the traffic lights and the opening and closing of the vehicle blocking bar through the calculation of the traffic congestion in which the number of vehicle objects is compared (S706).

Hereinafter, a detailed process of step S702 of the intelligent vehicle intersection signal control method according to an embodiment of the present invention will be described with reference to FIG. 10.

First, the photographing means photographs a vehicle running or stopped while aiming at one direction or the other direction of the road construction section (S802).

Then, the photographing means transmits the photographed image to the object detection means connected through the wired or wireless network (S804).

Hereinafter, a detailed process of step S704 of the intelligent vehicle intersection signal control method according to an embodiment of the present invention will be described with reference to FIG. 11.

After step S702, the object detection means recognizes the vehicle object from the video stream of the image received from the photographing means (S902).

Then, the object detection means counts the number of vehicle objects present on the frame of the video stream for each set unit time (S904).

Hereinafter, a detailed process of step S706 of the intelligent vehicle intersection signal control method according to an embodiment of the present invention will be described with reference to FIG. 12.

After step S704, the intersection signal control means classifies the number of vehicle objects received from the object detection means by identification ID (S1002).

Subsequently, the intersection signal control means selects an identification ID having a large number of vehicle objects for each identification ID (S1004).

Then, the intersection signal control means turns on the traffic light corresponding to the selected identification ID and generates a vehicle intersection signal for controlling the opening and closing of the vehicle blocking bar (S1006).

As described above, according to the intelligent vehicle crossing signal control method as described above, the human/physical cost required to install equipment for vehicle recognition is reduced, and active traffic flow control is possible by vehicle crossing signals without being limited to a predetermined pattern. In addition, there is an effect that intelligent traffic flow control is possible by vehicle crossing signals that are variable in special situations without an operator for traffic control.

As described above and shown in connection with a preferred embodiment for illustrating the technical idea of the present invention, the present invention is not limited to the configuration and operation as shown and described as described above, and deviates from the scope of the technical idea. It will be well understood by those skilled in the art that a number of changes and modifications can be made to the present invention without. Therefore, all such appropriate changes and modifications and equivalents should be considered to be within the scope of the present invention.
