Description

{TRAFFIC ACCIDENT MONITORING SYSTEM}

The present invention relates to a traffic accident monitoring system mounted on a median block of a road for monitoring traffic accidents and transmitting related information.

There are facilities installed on the roads so that the driver can accurately recognize the position of the lane, induce the traveling vehicle not to invade the lane, and provide safe driving. For example, a median, guardrail, and deliner module can perform this function. Especially, it is essential to install the facilities to reduce the possibility of accidents in areas where visibility is difficult due to environmental factors, areas requiring low speed operation of the driver, and places with high risk of accidents.

Conventionally, solar energy is converted into electrical energy and stored in a storage battery. In case of deterioration due to nighttime or deep fog, a self-luminous type deliner module or simple flat panel A reflection type retractor module for guiding the driver's eyes using light reflected by the headlamp of the traveling vehicle is widely used for lane guidance.

In recent years, there have been developed systems capable of more intelligently guiding the safe operation of a vehicle by utilizing modules installed on the road in building an intelligent transportation system (ITS).

For example, Korean Patent Laid-Open Publication No. 2016-0031364 relates to a system for providing information on a forward running vehicle on the road, in which a device installed at the center of the road detects a vehicle running on the road, And outputting an alarm, thereby enabling a vehicle running on the front to maintain a safety distance from the center separator.

However, such a device is capable of preventing a specific situation, for example, a median collision of a vehicle, and can not notify a rear vehicle of an accident of a preceding vehicle when a collision between vehicles or a driver is in a critical situation.

When a forward driving vehicle is suddenly bumped or collided at a high speed such as a highway, a secondary collision accident frequently occurs due to a rearward driving vehicle that does not know an accident and maintains a speed.

Accordingly, there is a need for a system that allows the rear driver to recognize the situation and use the detour or the deceleration according to the situation by effectively informing the rear driver of the emergency situation on the front using the module that can be installed on the road.

1 is a diagram illustrating a traffic accident monitoring system according to embodiments of the present invention.

Referring to FIG. 1, the traffic accident monitoring system 100 may include a traffic accident monitoring apparatus 110, a relay 120, and a control server 130.

The traffic accident monitoring apparatus 110 is mounted on a median (MS) (or guardrail) of a road (or a highway), and when a collision occurs in which a vehicle or the like is dispatched to the median (Or monitoring information) detected at the time of occurrence of a collision can be transmitted to a repeater (or a control server, a user terminal).

As shown in FIG. 1, the traffic accident monitoring apparatuses 110 may be disposed adjacent to each other. However, the present invention is not limited to this, and the traffic accident monitoring apparatuses 110 may be disposed apart from each other.

The specific configuration of the traffic accident monitoring apparatus 110 will be described later with reference to FIG. 2 and FIG.

The repeater 120 may be connected to the traffic accident monitoring apparatus 110 through a wireless communication network and may transmit the sensing information provided from the traffic accident monitoring apparatus 110 to the control server 130. The repeater 120 may be connected to the control server 130 in a wired manner and the repeater 120 may be included in a built-in system (for example, a overspeed camera).

The control server 130 can determine whether a collision accident (or a traffic accident) has occurred based on the sensing information transmitted through the relay 120, and estimate the magnitude of the collision accident. The control server 130 receives sensing information (for example, identification information of the traffic accident monitoring apparatus 110 transmitted together with the sensing information) and placement information (for example, placement information of the traffic accident monitoring apparatus 110) It is possible to determine the point of occurrence of the accident. The control server 130 notifies the occurrence of a collision to a related authority (for example, a road traffic department, a safety management system (for example, 119 safety report center) A driver located within a certain distance).

Hereinafter, the configuration of the traffic accident monitoring apparatus 110 and the operation of the control server 130 will be sequentially described.

2 is a view showing an example of a traffic accident monitoring apparatus included in the traffic accident monitoring system of FIG. 3 is a block diagram showing an example of the traffic accident monitoring apparatus of FIG.

Referring first to FIG. 2, the traffic accident monitoring apparatus 110 may include a main body 210 and an impact absorbing pad 220 (or a shock absorbing unit). The body 210 is realized in a rectangular shape and can be disposed on the upper surface (or upper end) of the median separator MS. The main body 210 may include a communication unit 310, a warning display unit 330, a power supply unit 240, and a control unit 350 shown in FIG.

The shock absorbing pads 220 may be disposed on support pads extending downward (or downward) from the body 210 (i.e., on the sides of the support pads) to cover both sides of the median separator. The impact absorbing pad 220 is formed of a plate-shaped flockstick, urethane or the like, and can absorb a shock applied to the median separator.

According to the configuration of the traffic accident monitoring apparatus 110 shown in Fig. 2, the traffic accident monitoring apparatus 110 can be set on the median MS (or on the upper end of the median MS) . Further, the lower end of the traffic accident monitoring apparatus 110 (i.e., the end of the support pad) or the like can be fixed to the median separator by bolts or the like.

2 and 3, the traffic accident monitoring apparatus 110 includes a communication unit 310, a sensor unit 320, a warning display unit 330, a power source unit 340 And a control unit 350. [0033]

The communication unit 310 forms a communication channel with the relay 120 (or the control server 130, a user terminal, and the like) and can transmit data. Here, the data may include monitoring information including sensing information generated by a sensing unit 320 described later, identification information assigned to the monitoring device, and the like. The communication unit 310 is provided in the main body 210 of the traffic accident monitoring apparatus 110 and can transmit data through an antenna (not shown).

In one embodiment, the communication unit 310 may utilize a low power wireless communication technology. For example, the communication unit 310 may communicate data with the relay 120, the control server 130, or the like using a long range (LoRa) communication technology, or may transmit data using a low power Bluetooth (BLE) For example, a terminal carried by a driver / passenger of an accident vehicle).

The sensor unit 320 may generate a sensing signal by sensing pressure or vibration applied to the center separator MS. In addition, the sensor unit 320 may sense a vehicle (or an object) adjacent to the traffic accident monitoring apparatus 110. [

In embodiments, the sensor portion 320 may include a pressure sensor, a vibration sensor, and a proximity sensor.

The pressure sensor can generate the first sensing signal based on the pressure applied to the median separator MS. For example, the pressure sensor may be implemented as a general pressure sensor, and may be disposed between the support pad and the impact absorbing pad 220. For example, the pressure sensor is implemented with the second sensor SEN2 and the fourth sensor SEN4 shown in Fig. 2, and the second sensor SEN2 and the fourth sensor SEN4 are implemented with the median (MS) (Or pressure) exerted from directions respectively arranged in the first and second directions.

The vibration sensor can detect the vibration of the center separator MS and generate the second sensing signal. For example, a vibration sensor may be included in the body 210 and implemented.

The proximity sensor can generate a third sensing signal by sensing a vehicle adjacent to the center MS using ultrasonic waves or a laser. For example, the proximity sensor is implemented by a general ultrasonic proximity sensor and is implemented with the first sensor SEN1 and the third sensor SEN3 shown in Fig. 2, It can detect the vehicle that is located. In addition, the proximity sensor may include a plurality of proximity sensor modules, taking into account the performance of the proximity sensor (e.g., detection distance / area). For example, the first sensor SEN1 includes first through third sensor modules SEN1a, SEN1b, and SEN1c sequentially arranged in the horizontal direction, and the first through third sensor modules SEN1a, SEN1b, SEN1c) can sense the vehicle in different areas.

Meanwhile, the sensing information (e.g., the first to third sensing signals) generated by the sensor unit 320 may be used in the control server 130 to calculate / estimate the occurrence of the traffic accident and the magnitude of the occurrence of the traffic accident . This will be described later with reference to FIG.

The warning display unit 330 may display various characters, figures, arrows or pictures, or color lights (e.g., blue light, yellow light, red light) to provide traffic accident related information to a user of the vehicle approaching from behind .

In one embodiment, the warning indicator 330 may be implemented as a light emitting device (e.g., a lamp) that displays at least one of blue light, yellow light, and red light. For example, the warning indicator 330 may be implemented as the first warning light WL1 or the second warnings WL2 shown in FIG. 2 and may be implemented as a light emission control (not shown) provided from an external (for example, the control server 130) Based on the signal, one of blue light, yellow light, and red light can be displayed. Here, the color of the warning light may be determined based on the existence of a traffic accident and the distance to the traffic accident. For example, when there is no traffic accident ahead, the color of the warning light is emitted in blue or yellow, Can emit red light. For example, the blue light indicates a safe state without traffic accident within 2KM ahead, the yellow light indicates a state of caution in front of 2KM ahead, and the red light indicates a warning state in front of 1KM ahead of traffic accident have.

On the other hand, the first warning light WL1 and the second warning light WL2 shown in FIG. 2 can emit light in mutually different directions. For example, the first and second sensors SEN1 and SEN2 and the first warning light WL1 are interlocked, and based on the sensing information sensed by the first and second sensors SEN1 and SEN2, If it is determined that the light is generated, light can be displayed through the first lamp WL1. Accordingly, it is possible to provide information to the driver of the vehicle approaching from the rear in the lane where the traffic accident occurred, and to prevent unnecessary warning information from being provided to the driver in the opposite lane (or to cause confusion due to the warning information) . Similarly, the second alarms WL2 are interlocked with the third and fourth sensors SEN3 and SNE4, detect a traffic accident of the corresponding lane, and provide information to the vehicle driver of the corresponding lane.

Meanwhile, the warning display unit 330 may further include a warning sound output module for generating / outputting a warning sound. That is, the warning display unit 330 generates sound with light, thereby enabling drivers to recognize the occurrence of a traffic accident more quickly.

In the embodiments, the warning display unit 330 may move along a separate guide rail (or guide groove) formed in the traffic accident monitoring apparatus 110. For example, instead of including the warning display unit 330, the traffic accident monitoring apparatus 110 can carry the warning display unit 330, and when a traffic accident occurs, the vehicle driver can display the warning display unit 330 It is mounted on the accident monitoring apparatus 110 (or a median) and moved rearward (that is, rearward with respect to the running direction of the lane in which a traffic accident occurred), thereby visually informing drivers of the traffic accident. The configuration in which the warning display unit 330 is moved will be described later with reference to FIG.

The power supply unit 340 may generate and supply / supply power necessary for driving the traffic accident monitoring apparatus 110. [ The power supply unit 340 may include a power supply unit and a self-power generation unit. The power supply unit is provided in the main body 210 of the traffic accident monitoring apparatus 110 and supplies power to the traffic accident monitoring apparatus 110, and may be implemented by a general power converter or the like. The self-power generating unit is disposed on the upper surface of the main body 210 to convert solar energy into electric energy and provide the power to the power supply unit. Alternatively, the self-power generating unit may be disposed between the support pad of the traffic accident monitoring apparatus 110 and the impact- The vibration can be converted into electric energy and supplied to the power supply unit.

The control unit 350 controls operations of the communication unit 310, the sensor unit 320, the warning display unit 330, and the power supply unit 340, and can control data transfer between them. For example, the control unit 350 may cause the communication unit 310 to transmit the sensing information generated by the sensor unit 320 to the outside, and may display the warning display unit 330 on the basis of the sensing information or the externally provided emission control signal. Can be controlled.

The control unit 350 primarily determines whether a traffic accident has occurred based on the sensing information (or the monitoring information) generated by the sensor unit 320, and displays a warning on the warning display unit 330 based on the determination result. Can be controlled. For example, when the magnitude of the pressure included in the first sensing information (i.e., the pressure due to the impact) is greater than the reference pressure, the controller 350 determines that a traffic accident has occurred, The alarm display unit 330 of the traffic accident monitoring apparatus 110 and the alarm display unit of adjacent traffic accident monitoring apparatuses) operate. In this case, even if a communication network failure occurs, the fact of a traffic accident can be spread more quickly and stably.

As described with reference to FIGS. 2 and 3, the traffic accident monitoring apparatus 110 is structurally designed to protect the vehicle / user by mitigating the impact caused by the collision through the impact absorbing pad 220 and to prevent damage to the center separator MS (For example, pressure and vibration) applied to the median separator through the sensor unit 320 and a vehicle (for example, an accident vehicle) stopped adjacent to the median separator, (Or warning / attention information, for example, yellow light) is displayed on the basis of the traffic accident information (e.g.

FIG. 4 is a flowchart illustrating a process of determining a traffic accident in a control server included in the traffic accident monitoring system of FIG. 1;

Referring to FIGS. 1 and 4, the control server 130 (or a traffic accident determination method) may receive / acquire sensing information from the traffic accident monitoring apparatus 110 (S410).

2 and 3, the sensing information includes a first sensing signal indicative of the pressure sensed by the pressure sensor of the sensor unit 320, a second sensed signal indicative of the sensed vibration through the vibration sensor, Sensing signal, and a third sensing signal indicative of the vehicle sensed through the proximity sensor (e.g., vehicle, object adjacent to the median (MS)).

The control server 130 may periodically determine whether the magnitude of the first sensing signal (or pressure) is greater than a reference pressure (or a reference pressure value) (S420). When the size of the first sensing signal is larger than the reference pressure, the control server 130 can determine that a traffic accident has occurred.

When it is determined that a traffic accident has occurred, the control server 130 determines whether the traffic accident monitoring device 110 is located adjacent to the traffic accident monitoring device 110 (or located within a specific distance based on the traffic accident monitoring device 110) (I.e., the pressure signal corresponding to the first sensing signal) of the accident monitoring apparatus 110 (S430).

The vehicle may collide with the median separator (or the corresponding traffic accident monitoring apparatus 110) and may immediately be thrown out, but the vehicle can move with the median collision.

The control server 130 may determine a first accident scale indicating the degree of damage of the accident vehicle (or the collision vehicle) based on the adjacent first sensing signal (or pressure signal) (S440).

For example, when the first sensing signal is larger than the first reference signal, the control server 130 determines that the first incident scale is "small" in the middle / middle / small, Or the first pressure signal) is larger than the first reference signal, the degree of the first accident scale can be changed from "small" to "middle". In another example, when the second sensing signal is larger than the second reference signal, the control server 130 may determine that the first incident magnitude is "medium ".

Thereafter, the control server 130 may determine the second incident size based on the change of the vehicle detection signals detected by the traffic accident monitoring apparatus 110 and the adjacent traffic accident monitoring apparatuses (S450).

For reference, although the traveling vehicle can be continuously detected through the proximity sensor of the traffic accident monitoring apparatus 110, the third sensing signal by the traveling vehicle can be continuously changed according to the traveling vehicle. In contrast, in the case of an accident vehicle, it is possible to maintain the state where the vehicle is stopped for a predetermined time before the occurrence of an accident, so that the third sensing signal by the accident vehicle can be maintained at a specific value for a predetermined time or longer. For example, when the traffic accident monitoring apparatus 110 can detect one passenger vehicle or an object of a 5 m section through the proximity sensor, when the accident vehicles are detected by the three traffic accident monitoring devices, The accident size can be estimated as 3 or 15m, and when the accident vehicles are detected by the five traffic accident monitoring devices, the second accident scale can be estimated as 5 or 25m. An accident handling vehicle or the like corresponding to the second accident scale can be quickly disposed on the spot.

As described with reference to FIG. 4, the control server 130 determines whether or not a collision has occurred based on the first sensing signal (or the pressure signal) of the sensing information, (Or pressure sensing signals) obtained from adjacent traffic accident monitoring devices, based on the sensed signals (or pressure signals) It is possible to determine the scale of the second accident indicating the scale of damage of the accident-damaged vehicle. Based on the first and second accident scales, the support scale of the support vehicles (e.g., tow vehicle, ambulance, etc.) for accident handling can be determined and rapid accident handling support can be achieved.

5 is a view showing another example of the traffic accident monitoring system of FIG.

Referring to FIGS. 1 and 5, the traffic accident monitoring system 100 may further include a user terminal 510.

The user terminal 510 can be located within a predetermined distance / range from the traffic accident monitoring apparatus 110 as a terminal carried by the driver and the passenger of the accident vehicle. For example, it may be a terminal of a user located within 5 m in consideration of the communication distance of the traffic accident monitoring apparatus 110.

As described with reference to FIG. 1, the monitoring device 110 may utilize long-range wireless communication technology and / or short-range wireless communication technology. For example, when using a long distance wireless communication technology such as Laura communication, the monitoring device 110 may provide sensing information (or monitoring information) to the control server 130 through the repeater 120 (and wired communication network) . The monitoring device 110 provides at least a portion of the sensing information to the user terminal 510 and the user terminal 510 responds to the user ' And provide accident information to the control server 130. Here, the user terminal 510 can transmit data using a wireless communication scheme such as 3G, LTE, and the like.

For example, when an impact on the median separator MS (or the traffic accident monitoring apparatus 110) occurs, the traffic accident monitoring apparatus 100 is located at a nearby location (for example, within a Bluetooth communication distance of 5 m) The user terminal 510 can search the user terminal 510. Here, the user terminal 510 may be a terminal for which the same communication function is activated. In recent years, the number of vehicles (for example, blue link technology) equipped with a communication function is also increasing, and the user terminal 510 may be a communication terminal mounted on a vehicle. When the user terminal 510 is searched, the traffic accident monitoring device 110 detects identification information (for example, ID) and impact information (for example, pressure / vibration size) of the traffic accident monitoring device 110 , As illustrated in FIG. 5, in the form of a text message / pop-up message to the user terminal 510. In addition, the traffic accident monitoring apparatus 110 may further include information on the number / size of the detected garage vehicles to the user terminal 510. Then, the user terminal 510 responds to the input information of the user (for example, a touch input for "Yes ", which agrees to transmission of the accident information, or a non- , And can transmit traffic accident information (i.e., accident information including identification information, impact information, and the like) to the control server 130. On the other hand, the control server 130 determines / determines an accident time / time based on the time when the traffic accident information is transmitted to the user terminal 510 / the control server 130, (Eg, the size of the pressure / vibration, the number of accident vehicles, or the range in which an accident vehicle is detected) based on the accident information (ID) and the placement information. For example, the control server 130 can classify the magnitude of traffic accidents as large / medium / small based on the magnitude and range of pressure / vibration. The control server 130 provides the information of the user terminal together with the traffic accident information to the relevant organization (for example, the 119 safety report center), and the related organization can use the user terminal information to more accurately identify the accident situation / .

5, the traffic accident monitoring system 100 according to the embodiments of the present invention generally transmits sensing information (or monitoring information) generated from the monitoring device 110 to the relay device 120 through the relay device 120 (For example, the user terminal / vehicle terminal of the accident vehicle in which the Bluetooth communication function is activated) by providing the sensing information to the control server 130, The user terminal 510 can send the accident information to the control server 130 based on the user's intention to enter the agreement. Therefore, even if a communication network failure occurs between the monitoring apparatus 110 and the relay apparatus 120, the traffic accident information can be propagated more quickly and accurately.

6 is a view showing another example of a warning display unit included in the traffic accident monitoring apparatus of FIG.

2, 3, and 6, the warning display unit 600 (or the warning display unit) includes a traffic accident monitoring apparatus 110 (or a main body 210 of the traffic accident monitoring apparatus 110, G2, and / or guide rails G3, G4 formed on the guide rails (MS)). For example, the warning display unit 600 can display accident occurrence information, attention information, and the like while moving along the median remotely (MS) in the backward direction (that is, in the backward direction) on the basis of the accidental driving lane.

First, the warning display unit 600 may include a body module 610, a connection module 620, and a display module 630.

The main body module 610 includes a communication module, a movement distance calculation module for calculating the distance traveled by the warning display portion 600, and a movement distance calculation module for moving the warning display portion 600 from the outside (for example, And a movement module. For example, the moving module may include a motor for generating a rotational driving force, and a roller mounted on the guide grooves G1 and G2 / guide rails G3 and G4 and rotating according to the rotational driving force. For example, the distance calculating module can calculate the distance based on the driving time / number of rotations of the motor, the number of rotations of the roller, and the like. The calculated distance can be displayed through the display module 630. [

The connection module 620 is disposed between the main body module 610 and the display module 630 and can connect them. For example, the connection module 620 is connected to the main body module 610 and / or the display module 630 in a rotatable / foldable manner, and can transmit power and information necessary for driving the display module 630.

The display module 630 can display characters, pictures, and the like on one side. For example, as shown in FIG. 6, the display module 630 displays the accident occurrence information, and displays the accident occurrence information on the basis of the distance display portion (e.g., For example, 00 M). Display module 630 may have a mesh-like surface to reduce wind resistance.

Meanwhile, the main body 210 (or the upper structure of the center separator MS) of the traffic accident monitoring apparatus 110 may include guide grooves G1 and G2 and / or guide rails G3 and G4. For example, the first guide groove G1 is formed in a concave groove shape on one side or both sides of the upper surface of the main body 210, and the groove is formed in the longitudinal direction of the main body 210 The extending direction of the center separator, and the running direction). It is preferable that the first guide groove G1 is formed on one side of the main body 210 in order to prevent the power supply portion 340 (or the solar power panel as the self-generating portion) from being overlapped with the first guide groove G1 described with reference to Fig. 1 . In another example, the second guide groove G2 is similar to the first guide groove G1 and can be formed on the side surface of the main body. For example, the third and fourth guide rails G3 and G4 may be formed in place of the first and second guide grooves G1 and G2, and the third and fourth guide rails G3 and G4 may be formed. G4 may be implemented as convexly protruding rails instead of grooves. The main body 210 of the traffic accident monitoring apparatus 110 (or the median separator MS) may not be used because the vehicle accident monitoring apparatus 110 is exposed to the external environment, It may be preferable to form the guide groove G2 on the side surface or to include the third and fourth guide rails G3 and G4. Although the first and second guide grooves G1 and G2 and the third and fourth guide rails G3 and G4 have a rectangular sectional shape, the present invention is not limited thereto. For example, the convex portion, the concave portion may have an acute angle or an obtuse angle, and known shapes can be applied if the warning display portion 600 can be mounted.

The warning display unit 600 may be mounted on one or both of the first and second guide grooves G1 and G2 and the third and fourth guide rails G3 and G4. 6, the warning indicator 600 may be mounted on the first and second guide grooves G1 and G2 (or guide rails). A traffic accident may occur in both the driving lane and the opposite lane of the road. In this case, since the other warning display units must move in different directions, the warning display unit 600 is mounted in a direction adjacent to the lane, And may be configured to provide incident / attention information. That is, the warning display unit 600 is mounted on the first and second guide grooves G1 and G2 adjacent to the driving lane and moves in the direction opposite to the driving direction, And the third and fourth guide rails G3 and G4 adjacent to the opposite lane are equipped with different warning indicators so that they can provide relevant information only to drivers in the opposite lane.

6, the warning display unit 600 is mounted on a guide groove and / or a guide rail formed in the main body 210 (or the upper structure of the center separator MS) of the traffic accident monitoring apparatus 110 So that it is possible to provide traffic accident information to the rear drivers while moving in the direction opposite to the traveling direction. In addition, the warning display unit 600 can display more accurate traffic accident information to other drivers by reflecting the moving distance information in the traffic accident information. The warning display 600 described with reference to FIG. 6 may be implemented as a separate warning display device, and may be used when a vehicle accident occurs while the vehicle driver is carrying a vehicle such as a tripod. Particularly, the warning display unit 600 can control the movement of the user through the wired / wireless control system and can provide accurate distance information, thereby eliminating the risk of the tripod installation.

FIG. 7 is a view showing another example of the traffic accident monitoring apparatus of FIG. 2. FIG.

1, 2 and 7, the traffic accident monitoring apparatus 700 shown in FIG. 7 can monitor a traffic situation while moving along a median (MS) in a running direction or a running direction of the vehicle .

7, the traffic accident monitoring apparatus 700 is mounted on the median separator MS, spaced apart from the median separator MS by a specific distance, and includes the moving units 710a, 710b, and 710c, (720).

The moving units 710a, 710b, and 710c are implemented with the moving module described with reference to FIG. 6, and may be movably coupled to the guide grooves and / or guide rails formed on the upper, side, and the like of the center separator MS.

The moving units 710a, 710b and 710c (or the traffic accident monitoring apparatus 700) operate based on a movement control signal provided from the outside (for example, a movement control signal provided from the control server 130) .

The examining unit 720 can check the state of the median separator MS. For example, when the median separator MS is made of concrete, the examiner 720 can detect the strength, defects, and cracks of the median separator without damaging the median separator MS by using a general shim hammer or ultrasonic technique. And so on.

If an impact is applied to a median (MS) that has defects, cracks, etc., fragments of a median (MS), a collision vehicle, etc. may be crossed to the opposite lane and the scale of the accident may increase. MS) is not easy to test (for example, the lane should be blocked and the test should be conducted).

7, the traffic accident monitoring apparatus 700 moves along the center separator MS using the moving units 710a, 710b, and 710c, and when a collision occurs, or when the traffic accident monitoring apparatus 700 (For example, when there is a vehicle that has collided with the median MS), and provide the detected information to the control server 130. In addition, the traffic accident monitoring apparatus 700 can perform a nondestructive inspection on structural defects of a median (MS) constructed of concrete or the like by using an inspection unit 720 to be inspected. It is possible to prevent the spread of the traffic accidents by securing the safety for the median (MS).
