Description

[0001] The present invention relates to a position-based real-

The present invention relates to a location-based real-time vehicle information display system, and more particularly, it is capable of providing detailed vehicle information on a specific location on a road in real time to a driver, Based real-time vehicle information display system capable of displaying accurate real-time vehicle information through a single monitor screen.

As the economy expanded and advanced, the number of roads and vehicles increased, and the number of incidents including vehicle congestion, traffic accidents, and traffic violation vehicles also increased in proportion to the increase in the number of roads and vehicles.

Accordingly, the vehicle information of the predetermined road is collected using the vehicle detection means, and traffic information including the vehicle density, the congestion rate, the vehicle speed, and the offending vehicle is generated based on the collected vehicle information, (Intelligent Transportation System (ITS)) is widely used.

The conventional traffic information system comprises a vehicle sensing means for sensing a vehicle traveling in a predetermined sensing section and a controller for generating vehicle information such as vehicle speed, density, and congestion ratio by analyzing the sensing signal transmitted from the vehicle sensing means A traffic information management server for generating real time traffic information by processing the vehicle information transmitted from the vehicle detector, and a terminal for outputting the real time traffic information transmitted from the traffic management server to the traffic management server. At this time, the terminal is a digital terminal having output means and communication interface module such as a smart phone and OBE (On Board Equipment) and outputs real-time traffic information received from a traffic management server through a data communication network.

The vehicle detection means of the vehicle detector detects a vehicle traveling on a predetermined detection section or point, and when a vehicle is detected, generates a detection signal and transmits the detection signal to the controller.

In this case, the vehicle detector typically includes a VDS (Vehicle Detection System) for detecting a vehicle passing through a specific point according to the type of the vehicle detection means and generating vehicle information, And the section detector and the section detector will be described in detail later with reference to FIG. 1 and FIG. 2.

1 is an exemplary view for explaining a point detector.

The point detector 150 of FIG. 1 detects a vehicle passing through a predetermined position (point) X1 such as a loop detector, a laser, and the like to generate vehicle information. At this time, the generated vehicle information is transmitted to the traffic management server, and the traffic management server typically replaces the vehicle information for the specific location with the real-time traffic information for one link 170 and transmits the same to the connected terminal.

That is, when the point detector 150 sets the predetermined sensing area as one link 170 formed by the node 1 171 and the node 2 172, the point detector 150 detects the entire area S1 + S2 of the link 170, The traffic management server processes the vehicle information of the specific location received from the point detector into real time traffic information of the link 170 and transmits the processed information to the terminal.

Accordingly, the real-time traffic information using the point detector is substantially different from the traffic information for the entire link 170. Such inaccurate traffic information adds confusion to the determination of the travel route of the driver, The reliability is lowered.

In particular, since the link 170 is formed with a large distance of at most 9 km or more, the traffic information generated by the ground check base represents only the traffic information for the specific location X1 of the link 170, The area of the actual detection area is remarkably low, so that it can not be replaced with the traffic information for the entire area of the actual link 170. [

In order to overcome such a problem, a section detector capable of detecting a traveling vehicle for the entire area of the link 170 has been studied and used.

2 is an exemplary diagram for explaining a section detector.

The interval detector includes an entrance detection unit 161 and an entry detection unit 163 installed at the node 1 171 and the node 2 172 respectively forming the link 170 as shown in FIG. The detection unit 161 detects a vehicle entering the link 170 from the link 170 by the advance detection unit 163.

The entry detection unit 161 and the entry detection unit 163 receive the vehicle identification information from the in-vehicle terminal OBE of the passing vehicle through the DSRC and transmit the received vehicle identification information to the controller (not shown) Lt; / RTI >

The controller uses the transmitted vehicle identification information to determine the time at which each of the vehicles entered the link 170, the time at which the vehicle 170 entered from the link 170, the speed, the vehicle density of the link 170, Therefore, the traffic management server can generate accurate traffic information for the entire area of the link 170. [0050] [43]

However, since the interval detector is configured in such a manner that the vehicle speed is calculated using the entry time, the advance time, and the link 170 distance after the vehicle passes through the node 2 172, the real time traffic information generated by the traffic management server Since the vehicle is generated after elapse of the calculation time since the vehicle passed through the second node 172, it can not generate substantially real-time traffic information.

That is, the real-time traffic information provided by the traffic management server is not traffic information for the current link 170 but traffic information about the link 170 about 5 to 10 minutes before the current time, Is not accurate information on the road at the current time point, it increases the driver's confusion and lowers the reliability of the traffic information. In particular, when a road bottleneck occurs in the link 170, the damage due to the non-real-time traffic information is further increased.

Also, since the interval detector is configured to detect the vehicle passing through the node 1 171 and the node 2 172 to generate vehicle information, the vehicle information can be detected in units of links 170 having a distance of at least 5 Km And is configured not to be able to sense a vehicle in motion within link 170 except when passing through node 1 171 and node 2 172. Thus detailed vehicle information about the exact position or section in link 170 And the like.

In order to overcome this disadvantage, the link 170 must be formed at a short distance, but when the link 170 is formed at a short distance, the installation and operation costs are excessively increased.

Also, since the speed detector is configured to detect the speeding vehicle by calculating the vehicle speed using the entering time and the advancing time passing through the node 1 171 and the node 2 172, It is often necessary to slow down the vehicle in order to lower the average speed so as not to be caught by the speed violation before passing through the vehicle.

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

3 is a configuration diagram illustrating a traffic management system according to an embodiment of the present invention.

The vehicle information display system 1 of FIG. 3 includes a controller 31, a radar transceiver 33 and a photographing unit 35. The vehicle information display system 1 includes a controller 31, At least one vehicle detector 3-1 for generating location-based vehicle information, which is vehicle information including direction, vehicle density, and distance between vehicles, in real time and acquiring an image of a predetermined shooting area S ', Based vehicle information and images received from the vehicle sensors 3-1 to 3-N and the vehicle detectors 3-1 to 3-N and collectively managing the collected vehicle information and images (7) for displaying vehicle information and images for a specific location in accordance with a predetermined graphic procedure, a traffic information management server (5) for monitoring the road, 1), ..., (3-N), the traffic management server 5 and the terminals 7 And a data communication network 6.

Fig. 4 is a configuration diagram showing the vehicle detector of Fig. 3; Fig.

4, the vehicle detectors 3-1, ..., and 3-N are installed apart from each other along the road, and transmit the radar to each predetermined sensing area S, A radar transmission / reception unit 33 for receiving a reflection signal, a photographing means 35 for photographing a predetermined photographing area S 'to acquire an image, and a controller 35 for analyzing the radar signals transmitted / And a controller 31 for generating location-based vehicle information which is vehicle information. At this time, the location-based vehicle information includes the position, speed, running direction, and distance between each of the detected vehicles.

The controller 31 analyzes the radar signal to detect the precise position (coordinate) of the detected vehicle, the speed, the traveling direction, and the distance between the front wheels, thereby generating the position-based vehicle information, Accordingly, it is possible to solve the problems of the conventional point detector or the section detector which can not provide traffic information to the driver in real time. The generated location-based vehicle information is transmitted to the traffic management server 5.

Further, the controller 31 transmits the photographed image obtained by the photographing of the photographing means 35 to the traffic management server 5.

The radar transceiver 33 receives the reflected signal after transmitting the radar to the sensing area S. At this time, it is preferable that the radar transmitting / receiving unit 33 is installed at the middle point of the sensing area S, and the transmitting / receiving distance of the radar transmitting / receiving unit 33 is approximately 450 to 550 m, Area.

The photographing means 35 photographs a predetermined photographing area S 'to acquire an image, and transmits the obtained image to the controller 31. [ At this time, the imaging area S 'is formed of the same area as the sensing area S or a part of the sensing area S.

5 is an illustration of a data packet for describing location based vehicle information generated by the controller of FIG.

The controller 31 analyzes the radar signals transmitted and received from the radar transmitting and receiving unit 33 to detect the position, speed, running direction, and distance between the respective vehicles, thereby generating the location-based vehicle information 300 of FIG.

Based vehicle information 300 includes the identification ID value 301 of the controller 31, the position information 302 of the preset sensing area S and the position information 303 of the preset sensing area S ' Are stored as bits D1, D2, and D3.

The position-based vehicle information 300 also includes data bits D4, D2, D3, D4, D4, D4, D4, D5), (D6), (D7), and (D8).

The traffic management server 5 stores the location information of the road and the cell location information obtained by dividing the road into predetermined areas and stores the information from the vehicle detectors 3-1 to 3-N When receiving the location-based vehicle information 300, the location-based traffic information is generated by matching the predetermined road location, the cell area, and the received location-based vehicle information 300, and stores the generated location-based traffic information in a database. At this time, when the traffic management server 5 receives the traffic information for the specific section from the connected terminal 7, the traffic management server 5 searches for the location-based traffic information stored in the database section, Based traffic information within a predetermined range and transmits the extracted location-based traffic information to the connected terminal 7.

When the traffic management server 5 receives the photographed image from the vehicle detectors 3-1, ..., and 3-N, the received traffic information is stored in the database unit, Thereby monitoring the road.

FIG. 6 is an exemplary view for explaining a cell region applied to the present invention, and FIG. 7 is an exemplary view for explaining when traffic information is displayed in a cell region of FIG.

6, the cell 600 is divided into a plurality of roads for displaying traffic information received from the traffic management server 5 at the terminal 7, and the radar transmission / reception unit 33, The area is determined in the traffic management server 5 by the resolution of the vehicle. That is, the resolution of each of the traffic management vehicle detectors 3-1, ..., and 3-N according to the radar transmission / reception unit 33 is preset and stored to detect the vehicle detectors 3-1, Based vehicle information is received from the radar transmitter-receiver unit 3-N, the resolution corresponding to the stored radar transmitter / receiver unit is searched to extract the resolution corresponding to the radar transmitter / receiver unit of the vehicle sensor that transmitted the data, Based traffic information to the terminal 7 and the terminal 7 divides the road according to the cell area included in the location-based traffic information received from the traffic management server 5, Information will be displayed. At this time, the process of calculating the cell area according to the resolution and the resolution in the traffic management server 5 will be described in detail with reference to FIG. 8 which will be described later.

That is, when traffic information received from a conventional traffic management server is displayed on a terminal, traffic information (including vehicle speed, vehicle density, congestion status, etc.) is displayed on a link basis as shown in FIG. 7, According to the invention, the traffic information displayed on the terminal 7 is displayed in units of cells having a small area divided into a plurality of links, so that the driver can recognize the traffic information for the accurate road position, (Resolution), the cell area is determined. Therefore, when the performance of the radar device is good (when the resolution is low), the vehicle information can be displayed by dividing the area into more detailed areas. At this time, the terminal 7 displays the cell in a predetermined color according to the vehicle speed, thereby allowing the driver to easily recognize the road traffic situation.

It is also preferable that the cell 600 divides each lane into a plurality of lanes so that the driver can view traffic information of each lane. For example, when a bottleneck phenomenon occurs on a one-lane road of a three-lane road due to a vehicle accident or the like, the driver can not recognize the bottleneck phenomenon because traffic information is displayed on a link basis in a conventional terminal. However, The traffic information is displayed on a cell-by-cell basis, so that the driver can precisely recognize the specific lane and specific location where the bottleneck occurs.

8 is an exemplary diagram for explaining the resolution applied to the present invention.

Referring to FIG. 8, when the radar transmitting / receiving unit 33 transmits and receives a radar to the sensing area S, noise is increased as the distance from the radar transmitting / receiving unit 53 increases, And thus the vehicle detection rate is lowered. That is, the controller 31 analyzes the radar signals when the two vehicles 701 and 702 are traveling on the adjacent road from the radar transmission / reception unit 33 to accurately detect the respective vehicles 701 and 702 However, when two vehicles 703 and 704 traveling at a long distance from the radar transmission / reception unit 33 are traveling, the remote vehicles 703 and 704 are detected as one vehicle.

That is, the resolution (specifically, the distance resolution) is defined as a minimum separation distance between objects that can distinguish each of the objects in the same direction at the farthest distance from the radar transmission / reception unit 33, , Manufacturer, type, and configuration. For example, when the resolution is 50 cm, the controller 31 has an error range of 50 cm because it can not distinguish vehicles having an interval of 50 cm or less.

Therefore, in the present invention, the terminal 7 displays the location-based traffic information received from the traffic management server 5 in units of cells, and the cell area is determined according to the performance (resolution) of the radar, thereby minimizing the cell within the error range Thereby minimizing information transmission errors.

A method for calculating the cell area by the traffic management server 5 according to the resolution is as follows.

The traffic management server 5 previously stores the preset lane width and the resolution (distance resolution) of the radar transmission / reception unit 33 and receives the location-based vehicle information from the vehicle detector 3, 1 < / RTI >

Equation 1

Cell area = k x distance resolution

Where k is a proportional constant.

The cell area information thus calculated is matched with the location-based traffic information and stored in the traffic management server 5.

The traffic management server 5 also receives the location information of the photographing area S 'of each of the photographing means 35 of the vehicle detectors 3-1, ..., and 3-N, ID value is previously stored and stored, and when receiving an image from the vehicle detectors 3-1, ..., and 3-N, the ID value of the vehicle detector and the position of the photographing area S 'are detected.

Also, the traffic management server 5 analyzes the image transmitted from the vehicle detectors 3-1, ..., and 3-N based on the predetermined image analysis algorithm, and outputs the vehicle image and the detected vehicle image And detects the position of the detected vehicle image (hereinafter, referred to as image-based vehicle position information) using the coordinates of the detected vehicle image and the position information of the photographing area S '.

The traffic management server 5 also receives vehicle position information of the position-based vehicle information 300 received from the vehicle detectors 3-1, ..., and 3-N (hereinafter, ) 301 with the image-based vehicle position information to determine that the vehicle information 300 and the sensing vehicle corresponding to the vehicle image are the same vehicle when the difference value of the two data is within a predetermined threshold value.

In addition, the traffic management server 5 gives an identification code for identifying the vehicle determined as the same vehicle when the vehicle information 300 and the sensing vehicle corresponding to the vehicle image are determined as the same vehicle.

Also, the traffic management server 5 matches the identification code and the position and coordinate information of the same vehicle to the location-based traffic information so that when the terminal 7 receives the traffic information and the image from the traffic management server 5, It is possible to accurately match the detection vehicle and the image through the identification code of the vehicle, the position of the same vehicle, and the coordinate information. For example, when the vehicle 'A' passes through the shooting area, the vehicle detector 3 transmits the captured image of the vehicle 'A' and the location-based vehicle information 300 for the vehicle 'A' And the traffic management server 5 analyzes the photographed image and the location-based vehicle information 300 as described above, and transmits the identification code for the vehicle 'A' and the location code of the vehicle 'A' And intra-image coordinate information to traffic information.

The terminal 7 includes display means for displaying contents such as a smart phone, navigation, OBE (On Board Equipment), and the like, and a communication interface 6 for supporting connection with the data communication network 6 Based traffic information and images received from the traffic management server 5 on a display means. It is needless to say that the vehicle information display system 1 may further comprise a base station for transferring data between the traffic management server 5 and the terminal 7 when the terminal 7 is an in-vehicle terminal.

In addition, the terminal 7 requests traffic information for a specific section to the traffic management server 5. When receiving the location-based traffic information and the shot image for the specific section requested from the traffic management server 5, By displaying the user interface displaying the information and the photographed image according to a predetermined graphical procedure on the monitor, the viewer can efficiently browse various information about the vehicles traveling at the correct position on one monitor screen.

In addition, the terminal 7 divides the road into a plurality of roads according to the cell area of the location-based traffic information transmitted from the traffic management server 5, detects the speed of each of the cells, and displays the cells in a predetermined color according to the speed .

For convenience of description, the terminal 7 requests the traffic management server 5 to request traffic information for a specific section. However, the terminal 7 includes a GPS module, The traffic management server 5 transmits the location-based traffic information corresponding to the received location information to the base station (not shown) or the terminal 7 Lt; / RTI >

When the terminal 7 displays the location-based traffic information and the image transmitted from the traffic management server 5, the terminal 7 maps the road to a virtual map (Virtual Map), which is a linear digital map corresponding to an actual road shape, (Hereinafter, referred to as a vehicle image) and an image (hereinafter referred to as a cell image) for the vehicles. At this time, when the terminal 7 is the in-vehicle terminal (OBE) and navigation, the image of the driver's vehicle is also matched to the virtual map in the virtual map and displayed on the display means. The method and structure for displaying the location-based traffic information and image by the terminal 7 will be described later in detail with reference to FIG. 14 and FIG.
