The present invention relates to the crackdown of a bus lane violation vehicle, and more particularly, to a method for cracking a bus lane violation vehicle using a bus.

In general, bus lanes are partitioned in the center or on both sides of the city's roads or highways. Only a designated bus can travel or stop on such a bus lane, and driving or stopping of a car, taxi, van, etc. is illegally punished.

In order to crack down on illegal driving and parking, public service personnel or traffic policemen would always be on the streets. In other words, if a public service worker or traffic police carries a video camera, and finds a passenger car on a bus lane, they use it as a basis for crackdowns. However, such a crackdown method requires a lot of manpower and concentrates on rush hour and the like, and thus there is a limit that crackdown is not properly performed even when illegal driving vehicles increase during the daytime.

In order to overcome these limitations, the recent spotlight is an unmanned enforcement system using a camera. That is, a system for installing a driverless camera system at a certain place and cracking down on a car that has been illegally driven or parked. These unmanned enforcement systems have made great strides in terms of labor cost savings and efficiency, but have caused another problem in that the effects of the enforcement are limited within the camera's shooting range. In other words, bus lanes are properly maintained only in the area of unmanned enforcement, and still in other areas. In order to solve this problem, the installation interval of the unmanned control system needs to be narrowed and the number of installations must be increased, which is considered as a problem that cannot be easily solved in that it requires high facility cost and operation cost.

(Explanation of crackdown of driving violation vehicle)

Hereinafter, referring to FIG. 4, a process of cracking down a driving violation vehicle using an apparatus for controlling a bus lane violation vehicle using a bus having the above configuration will be described.

First, an image is generated by photographing a vehicle in the bus-only lane 40 with an intermittent camera 122 mounted on the front of the driving bus 100. In addition, the background camera 124 is also synchronized with the intermittent camera 122 to photograph the surrounding background and the bus-only lane 30 together.

Then, it is identified whether or not the vehicle photographed based on the image is the bus-only lane 40 driving violation vehicle 42. This will be described in more detail as follows. The image processor 132 extracts a license plate image from the captured image. The number recognition unit 136 then recognizes the text information from the license plate image in 0.03 seconds. Then, the vehicle identification unit 131 finds out the structure of the vehicle number from the text information and identifies whether it is in the form of a license plate of a car, in the form of a license plate of a bus, in the form of a license plate of a taxi, or the like according to a license plate agreement previously input.

If the type of license plate of the bus is excluded from the target of enforcement, and if it is the type of license plate of a taxi, passenger car, van, etc., it is included in the target of the enforcement.

If it is determined that the violating vehicle 42, the wireless communication unit 110, the image photographed by the intermittent camera 122 and the background camera 124, the license plate image, text information, location information of the GPS unit 138 It is stored in the storage unit 134 and wirelessly transmitted to the outside.

The central server 200 receives data from the wireless communication unit 110 of the plurality of buses 100A, 100B, and 100N through the wireless Internet 210, and generates a penalty charge command based on the received data. To this end, by interworking with the National Police Agency server (not shown) through the central server 200 administration dedicated network 220, it is possible to obtain information about the owner of the violation vehicle.

Then, the administrative agency computer 230 of the local government (for example, ward office, etc.) connected to the central server 200 through the administrative dedicated network 220 receives and outputs the corresponding penalty charge command. This output form may be to print a penalty statement through a printer (not shown).

6 is a photograph showing an example in which various control data is displayed on a monitor screen in the central server 200 according to the present invention. As shown in FIG. 6, various interruption data are updated and listed on the desktop, and various multimedia data are popped up through a separate window.

Hereinafter, another method of control will be described with reference to FIG. 5. Referring to Figure 5, the shooting and the enforcement is the same as the previous embodiment. However, the intermittent information is not transmitted in real time but is stored in the storage 134, and this storage operation continues until the bus 100 returns to the garage 300.

After the bus 100 returns to the garage 300, the data in the storage unit 134 is transmitted to the garage computer 270 through the in-house wireless LAN 280.

The garage computer 270 then collects the data received from the various buses 100 and sends them to the central server 200 via the network 250. Since the process is the same as the description of Figure 4 will be omitted.

(Explanation of crackdown of parking violation vehicle)

Hereinafter, with reference to Figure 2 will be described a process of cracking down on a parking stop violating vehicle by using the cracking device of the bus lane violation vehicle using the bus having the configuration as described above.

First, as shown in FIG. 2, the first bus 100A intercepts the vehicles 42 and 44 and transmits the intermittent data to the central server 200. Then, after a predetermined time (for example, five minutes), a second bus that operates subsequently intervenes the vehicles 42 and 44 to transmit the intermittent data to the central server 200.

At this time, the central server 200 determines whether there is the same license plate text information at the same position among the control data of the first bus 100A and the control data of the second bus 100B. In other words, if the vehicle 44 is illegally parked, the vehicle 44 has the same position value by the GPS unit 138, and the text information of the same license plate. Then, it is possible to confirm that the same vehicle is illegally parked between at least the interruption times through the interruption times of the first and second buses 100A and 100B.

(transform Example )

(1) The crackdown can be managed by dividing the solid line section and the dotted line section of the bus lane based on the GPS signal, and specific points such as bus stops, taxi stops and crosswalks can be added to the crackdown.

(2) In addition, the central server can not only use the data sent from each bus as control information, but also can be used to collect traffic information.

(3) Although the parking regulation is explained through the first and second buses 100A and 100B, the parking regulation may be performed using a plurality of buses.

(4) In the present invention, a vehicle equipped with a camera may be a police car, a taxi, or the like in addition to a bus, or may be a vehicle of a private security company.

According to the method for cracking down a bus lane violation vehicle using a bus according to the present invention as described above, even if only a minimum crackdown equipment can be easily cracked or prevented a violation in advance of a vehicle in violation of the bus lane lane system.

In addition, it can be easily installed at the front of the bus, and the crackdown can be achieved with high reliability, and the complaints and disputes of the civil complaints about the crackdown can be minimized by securing sufficient evidence. The driver is not burdened with the operation of the control device.

In addition, by recognizing the potential that the bus itself can function as an unmanned enforcement device, it is possible to minimize the violation of the bus lane system.

In addition, the law application can be subdivided by classifying and detecting illegally driving vehicles on bus-only lanes and vehicles illegally parked on bus-only lanes.

In addition, it is possible to efficiently detect stolen vehicles, arranging vehicles, tax delinquent vehicles, etc. using a camera. And, even at night or in rainy weather, it is possible to use a separate lighting device, so it is possible to speed up the running.

Although the present invention has been described in connection with the above-mentioned preferred embodiments, it is possible to make various modifications or variations without departing from the spirit and scope of the invention. Accordingly, the appended claims will cover such modifications and variations as fall within the spirit of the invention.
