Traffic enforcement system on Multiline road

The present invention relates to a multi-lane control system, and in detail, determined by determining an enforcement lane, which is a lane where an enforcement is performed, based on traffic volume, vehicle average speed, occupancy rate, and number of violation vehicles for each lane of a multi-lane road. The present invention relates to a multi-road control system that allows a camera to photograph a traffic lane, so that a high-speed traffic lane is selected among the multi-lane roads efficiently by using a single camera to photograph a violation vehicle occurring in the traffic lane. .

As the number of cars and roads expands, automobiles provide enormous convenience throughout society, but continuous crackdowns on drivers are necessary because driving in violation of laws can lead to personal injury.

Accordingly, various detection methods and apparatuses for calculating a speed of a vehicle and photographing methods and apparatuses for photographing a vehicle when a violation vehicle is detected have been studied and used.

In particular, as the number of vehicles increased, the number of multi-lane roads also increased, and in order to control violating vehicles on such multi-lane roads, a plurality of cameras photographing each lane should be installed. However, such a method increases installation and maintenance costs. Practically, a problem arises that it is difficult to apply to an unmanned traffic control system installed throughout the road.

As a result, research on a multi-route control system using a single camera to control a multi-lane road has been conducted. However, the conventional multi-route control system uses a fixed method in which a camera photographs only a predetermined intervening lane among lanes, and a manpower at a control center. After monitoring the traffic conditions, if a crackdown lane with a high need for crackdown is selected, the camera is operating in a non-fixed manner to capture the crackdown lane under the control of the control center.

However, the fixed method of the conventional multi-route enforcement system decreases the efficiency of cracking down because the camera only photographs a specific lane regardless of the surrounding traffic conditions. The problem of driving in the excluded lanes occurs.

In addition, the conventional non-fixed method of the multi-track control system has the advantage of changing the control lane according to the surrounding traffic conditions, but the human resources are not only consumed and information is objective because the traffic situation information is collected and the decision of the control lane is made by the personnel. Has disadvantages.

The present invention is to solve this problem, the problem of the present invention is to automatically determine the enforcement lanes with high raid need among the multi-lane roads, and accordingly the camera is configured to shoot the violation vehicle of the enforcement lanes It is to provide a multi-track control system that can control a multi-lane road using a camera.

In addition, another problem of the present invention is that the control lane is determined based on the traffic volume, average speed, occupancy rate and the number of violation vehicles for each lane, compared to the case where the camera only photographs the specific lane among the multi-lane roads. It is to provide an intermittent intermittent system that is significantly increased.

In addition, another problem of the present invention is to provide a multi-crack control system that can reduce the installation cost, easy maintenance because it can control a multi-lane road using only a single camera.

In addition, another problem of the present invention is that traffic lanes, vehicle average speeds, occupancy rates, and number of violations during a predetermined period or a period entered by an administrator are determined based on the time zone and day of the week. It is to provide a multi-track enforcement system that determines an enforcement lane in response to the traffic situation characteristics of the vehicle.

Solution to Problem The present invention for solving the above problems is at least one sensor unit for detecting a vehicle traveling in each lane; A camera that performs shooting when a trigger signal is received from the outside; A controller for calculating a vehicle speed by using the detection signals received from the sensor units and detecting lane information corresponding to the sensor unit detecting the vehicle; When the vehicle speed and lane information are transmitted from the controller, traffic data is generated in proportion to the probability of occurrence of a speeding vehicle in each lane through the received vehicle speed, and is generated during a predetermined period T for each preset period t1. And comparing the traffic data of each lane with the control center server to determine the lane having the highest value as the traffic data. When the camera receives the control point, the camera controls the pan-tilt angle of the camera to form the intermittent lane, and transmits a trigger signal to the camera when the vehicle speed of the vehicle driving the intermittent lane is greater than a preset speed limit. To obtain an image of the violating vehicle in violation of the speed limit.

In addition, in the present invention, the traffic data is in the reverse order of the number of vehicles, and the control center server determines the received vehicle speed as the number of vehicles '1' and for each of the lanes during the specific period T for each period t1. After accumulating the number of vehicles, it is preferable to determine the lane having the lowest accumulated value as the intermittent lane.

In the present invention, the traffic data is the average speed, and the control center server calculates the average speed by dividing the number of vehicles by adding the vehicle speeds of each lane during the specific period (T) for each period (t1). It is preferable to determine the lane having the highest speed as the intermittent lane.

In the present invention, the traffic data is the number of offending vehicles, wherein the vehicle speed is a vehicle having the speed limit or more, the control center server is the number of offending vehicles of each lane during the specific period T for each period t1. It is preferable to determine a lane having the highest value of the number of violation vehicles as an intermittent lane.

In the present invention, the traffic information is in the reverse order of occupancy, the control center server calculates the occupancy of each lane during the specific period (T) for each period (t1), the lane with the lowest occupancy to the intermittent lane It is desirable to decide.

In addition, in the present invention, the specific period T is preferably input from an administrator.

According to the present invention having the above-mentioned problems and solutions, it is possible to control a multi-lane road using a single camera, thereby reducing costs and simplifying maintenance.

In addition, according to the present invention, since the intermittent lane is automatically determined periodically, the manpower consumption is reduced as well as easy to manage compared to the method of manually selecting the shooting lane and manually adjusting the pan-tilt angle of the camera. You lose.

In addition, according to the present invention, since the control lane is determined based on the traffic volume, average speed, occupancy rate and the number of violation vehicles of each lane, the control rate is significantly increased as compared to the case of continuously cracking down a specific lane.

In addition, according to the present invention, since the crackdown lane is determined based on data of a predetermined period or a period input by an administrator, the crackdown rate is further increased by preparing for traffic conditions of each lane according to time zone and day of the week.

The controller 3 is an intelligent terminal for controlling the sensor units 9-1, ..., 9-5 and the camera 5.

In addition, when the controller 3 receives the detection signals from the sensor units 9-1, ..., 9-5, the controller 3 calculates the speed of the traveling vehicle using the received detection signals. At this time, since the method of calculating the vehicle speed using the magnetic field signals generated from the loop coils 91 and 92 is a technique commonly used in the loop detector, detailed description thereof will be omitted.

In addition, the controller 3 transmits the calculated vehicle speed information and lane information of the sensor unit in which the traveling vehicle is sensed to the control center server 7 when calculating the speed of the traveling vehicle. At this time, the control center server 7 uses the vehicle speed information and the lane information received from the controller 3 to determine the intermittent lane where the camera 5 is to be photographed. In this case, the control center server 7 determines the interruption lane based on the vehicle information and the lane information will be described in detail with reference to FIG. 4.

The pan-tilt angle of the camera 5 is controlled. That is, when the controller 3 receives the intermittent lane information from the control center server 7, the controller searches for the database unit to extract the pan-tilt angle corresponding to the received intermittent lane information from the database unit, and the camera to have the extracted pan-tilt angle. By controlling (5), the camera 5 photographs the intermittent lane received from the control center server 7.

In addition, when calculating the vehicle speed as described above, the controller 3 compares the vehicle speed corresponding to the intermittent lane to the preset speed limit. If the vehicle speed is equal to or greater than the speed limit, the controller 3 determines the driving vehicle as the speed violation vehicle.

At this time, when the controller 3 detects the speed violation vehicle on the intermittent lane, the controller 3 transmits a trigger signal for operating the camera 5 to the camera 5 to obtain an image of the speed violation vehicle.

That is, since the control center server 7 determines the intermittent lane based on the traffic information of the specific period T, it is possible to determine the intervening lane according to the traffic conditions of each lane according to the time zone and the day of the week, and accordingly the present invention. In one embodiment of the multi-lane control system (1) is to considerably increase the rate of cracking compared to the case of continuously photographing one lane of the multi-lane road without considering the traffic situation. For example, in a traffic environment in which traffic of a specific lane is concentrated during the afternoon of Sunday afternoon, the control center server 7 decides a crackdown lane based on the traffic of the same time of the previous Sunday and needs to crack down among the multi-lane roads. It is possible to obtain an image for the lane with the highest degree.

When the vehicle speed and lane information are transmitted from the controller, traffic information is generated in proportion to the probability of occurrence of a speeding vehicle in each lane through the received vehicle speed, and is generated during a predetermined period T for each preset period t1. Comprising a control center server, characterized in that for comparing the traffic information of each lane to determine the lane having the highest value of the traffic information as the enforcement lane to be cracked,
When the controller receives the intermittent lane from the control center server, the controller controls the pan-tilt angle of the camera so that the photographing point of the camera forms the intermittent lane, and the vehicle speed of the vehicle driving the intermittent lane is preset. If the speed limit is higher than the multi-track enforcement system, characterized in that to obtain a video for the violating vehicle in violation of the speed limit by transmitting a trigger signal to the camera. The method of claim 1, wherein the traffic information is in reverse order of the number of vehicles,
The control center server determines the received vehicle speed as the number of vehicles '1', accumulates the number of vehicles in each lane during the specific period T for each period t1, and has a smallest accumulated value. And the lane is determined as the intervening lane. The method of claim 1, wherein the traffic information is an average speed,
The control center server calculates the average speed by dividing the number of vehicles by summing the vehicle speeds of the respective lanes during the specific period T for each period t1 to determine a lane having the highest average speed. Multi-censorship system, characterized in that determined by. The traffic information of claim 1, wherein the traffic information is a number of offending vehicles whose vehicle speed is greater than or equal to the speed limit.
The control center server calculates the number of violating vehicles of each lane during the specific period (T) for each period (t1), and determines the lane having the highest value as the interruption lane. Intermittent control system. The method of claim 1, wherein the traffic information is in reverse order of occupancy,
The control center server calculates the occupancy rate of each lane during the specific period (T) for each period (t1), and determines the lane with the smallest occupancy as the intermittent lane. The multi-track enforcement system according to any one of claims 1 to 5, wherein the specific period (T) is input from an administrator.
