1 is a conceptual diagram illustrating an overall flow in a traffic safety management system on a tunnel road according to an embodiment of the present invention.

Referring to FIG. 1 , the traffic safety management system 100 on a tunnel road collects various data related to the tunnel road, and detects abnormal signs that impair traffic safety on the tunnel road through analysis of the collected data, According to the detection of signs, traffic safety information can be provided to the tunnel manager to perform accident prevention activities.

As shown, the traffic safety management system 100 on the tunnel road analyzes the data acquired through the connection of the VDS (Vehicle Detection System), the Meteorological Agency OpenAPI, and the weather collection sensors installed at the entrance and exit of the tunnel road to the tunnel road. Simultaneous detection of multiple abnormalities that may occur in

Here, the VDS (Vehicle Detection System) is an example of a vehicle traffic condition detection system that detects a vehicle traveling on a tunnel road and a traffic condition. The same traffic data can be obtained from the vehicle traffic condition detection system.

The Korea Meteorological Agency OpenAPI is an open source that serves to provide weather data such as the current weather conditions and near future weather forecasts posted on the Meteorological Agency server. Weather data can be collected and acquired in real time.

The meteorological collection sensor is an example of a self-sensor facility installed at the entrance and exit of a tunnel road for self-measurement of at least one meteorological data of rainfall, snow cover, temperature, wind speed, and humidity.

In general, since most tunnel roads are located in mountainous areas, a weather environment different from the weather data posted by the Meteorological Agency server may appear, and different weather conditions may appear at the entrance, exit, and inside of the tunnel road due to topographical factors. There is this.

In consideration of this, the traffic safety management system 100 on a tunnel road of the present invention includes meteorological data obtained from the Meteorological Agency server through the Meteorological Agency OpenAPI, and weather data measured by itself through the weather collection sensors installed at the entrance and exit of the tunnel road. By combining this, it is possible to detect anomalies related to the weather condition based on more accurate weather data.

The traffic safety management system 100 on the tunnel road automatically displays the CCTV images taken on the tunnel road according to the detection of abnormal signs, automatically generates and propagates an SMS message to be sent to the terminal of the tunnel manager, and propagates it through the VMS. Activities to prevent accidents can be carried out, such as issuing a danger warning that notifies the speed limit or curfew.

For these accident prevention activities, the traffic safety management system 100 on the tunnel road transmits traffic safety information corresponding to the detected abnormal symptoms to the manager terminal, so that a countermeasure based on the traffic safety information can be taken. .

Here, the traffic safety information may be at least one of vehicle speed limit (the speed limit is different for each level), lane control, tunnel road entry prohibition, detour recommendation, vehicle spacing, tire chain installation, and light lighting.

In addition, the traffic safety management system 100 in the tunnel road of the present invention can select a priority for various abnormal symptoms that may occur in the tunnel road, so that it is possible to take countermeasures from abnormal symptoms with a high degree of risk.

As an example, the traffic safety management system 100 on a tunnel road can subdivide and detect abnormal symptoms on a tunnel road into 15 cases as shown in FIG. 3 , and the priority defined in each case By sequentially providing traffic safety information for accident prevention activities to the manager terminal according to the order, it is possible to quickly respond to abnormal symptoms with high risk.

Accordingly, the traffic safety management system 100 simultaneously detects various abnormal symptoms such as speed reduction, rapid increase in traffic volume, snowfall, heavy rain, icing on the tunnel road, and fire occurrence through analysis of various data acquired about the tunnel road. In addition, it is possible to improve the detection performance of individual anomalies.

That is, the traffic safety management system 100 calculates the change amount of traffic data such as the traffic amount and average driving speed by lane for each cycle, and compares it with the change amount calculated in the previous period, excluding the increase or decrease of the normal level of traffic volume and speed. By identifying fluctuations, it is possible to precisely detect abnormal signs of traffic data.

In addition, the traffic safety management system 100 is a combination of weather data obtained from the Meteorological Administration server and data obtained by its own sensor facility, and more accurately detects abnormal symptoms related to weather data on tunnel roads located mostly in mountainous areas. can do.

In addition, when an abnormal symptom is detected, the traffic safety management system 100 automatically outputs the CCTV image taken near the point where the abnormal symptom is detected or before and after the abnormal symptom is detected to the operator terminal to notify the detection of the abnormal symptom, Traffic safety information instructing actions to respond to the abnormal symptoms may be provided to the terminal of the tunnel manager to perform traffic accident prevention activities.

2 is a block diagram illustrating the configuration of a traffic safety management system on a tunnel road according to an embodiment of the present invention.

Referring to FIG. 2 , the traffic safety management system 200 in a tunnel road according to an embodiment of the present invention includes an acquisition unit 210 , a detection unit 220 , an output unit 230 , a processing unit 240 and It can be configured to include the database 250 .

The acquisition unit 210 acquires, as traffic data related to the tunnel road, traffic volume and average driving speed for each lane from the vehicle traffic situation detection system 261 that detects the traffic situation of the driving vehicle.

Here, a vehicle detection system (VDS) may be exemplified as an example of the vehicle traffic situation detection system 261 .

The acquisition unit 210 receives and acquires the traffic volume and average running speed for each lane of the tunnel road detected by the vehicle traffic situation detection system 261 at a predetermined period (eg, every 10 minutes) from the vehicle traffic situation detection system 261 Alternatively, by using the driving lane of the vehicle detected by the vehicle traffic condition detection system 261, the traffic volume and the average driving speed for each lane may be calculated and obtained at a predetermined period.

For example, when the driving lane of the vehicle detected by the vehicle traffic situation detection system 261 is identified, the acquisition unit 210 counts the number of vehicles traveling in the same lane for each cycle, and can calculate the traffic volume for each lane. , based on the traffic amount for each lane and the length of the lane, the average driving speed of the vehicle in the lane may be calculated.

The sensing unit 220 detects an abnormal symptom regarding the traffic condition on the tunnel road as the amount of change in the traffic data calculated for each period exceeds a reference value.

That is, the sensing unit 220 compares the obtained traffic data with the traffic data obtained in the previous period, calculates the amount of change in the traffic volume for each lane and the amount of change in the average running speed, and calculates at least one change amount, When the threshold value determined by a certain ratio of the amount of change calculated in the previous period is exceeded, it serves to detect an abnormal symptom regarding the traffic condition on the tunnel road.

For example, as the traffic data, when the traffic volume for each lane on the tunnel road is obtained, the detection unit 220 may indicate that the traffic volume is reduced by 80% or more than the traffic volume obtained in the previous period (eg, 10 minutes ago). It is possible to detect anomalies related to 'a sharp drop in traffic volume'.

In addition, as the traffic data, when the average driving speed for each lane on the tunnel road is obtained, the sensing unit 220 is 80% higher than the average driving speed obtained in the previous period (eg, 10 minutes before). When the abnormal decrease is detected, it is possible to detect an abnormal symptom related to 'vehicle speed decrease 1'.

The output unit 230 outputs the CCTV image of the tunnel road to the screen of the operator terminal (see FIG. 7A ), and notifies the detection of abnormal symptoms.

For example, the CCTV system 270 may maintain a CCTV image of a tunnel road taken by a camera inside the tunnel in association with the installation point of each camera, and the output unit 230 is photographed in the vicinity of the point where abnormal symptoms are detected. Or, by loading the CCTV image taken before and after the time when the abnormal symptom is detected, from the CCTV system, reproduced and output on the screen, the detection of the abnormal symptom can be notified to the system operator (operator terminal) side.

Accordingly, the system operator can immediately check the related CCTV image on the screen without having to search for or inquire the related CCTV image for the confirmation of abnormal symptoms, and can quickly determine whether an on-site dispatch of the manager terminal 280 is required. .

At this time, the output unit 230 outputs the CCTV image on the screen as shown in FIG. 7A, and at the same time, a notification message notifying the location of the point where the abnormal symptom is detected and the type of the abnormal symptom, and the amount of change in the acquired traffic data. By outputting the graph together on the screen 710, it can help the system operator to determine whether a countermeasure for traffic safety on the tunnel road is necessary.

Here, the notification message is, for example, "A speed decrease was detected at 300 m in the direction of Tunnel A to Seoul", "A speeding vehicle was detected in the second lane toward Seoul", "Traffic volume increased by more than 80%", etc. It can be written in text.

When a corresponding command is input by the operator terminal confirming the CCTV image, the processing unit 240 transmits traffic safety information corresponding to the abnormal symptoms retrieved from the database 250 to the manager terminal 280 designated for the tunnel road. send.

The traffic safety information may include countermeasures for preventing traffic accidents for each of the abnormal symptoms detected on the tunnel road.

As an example, the processing unit 240 may be configured if the abnormal symptom is related to 'a decrease in vehicle speed' or a 'surge in traffic volume' (or, if the abnormal symptom is related to 'increase in vehicle speed' or 'a sharp decrease in traffic volume'), the abnormal A message requesting an on-site dispatch to a point in the tunnel road where the symptom is detected is transmitted to the manager terminal 280 together with the CCTV image, and the vehicle speed limit or Traffic safety information related to lane control may be transmitted to the manager terminal 280 including the speed limit for each lane calculated in consideration of the traffic volume for each lane on the tunnel road.

For example, when an abnormal symptom related to a vehicle speed decrease is detected at a point 200 m in the direction of Seoul on the first lane of a tunnel road, the output unit 230 outputs the CCTV image photographed at the point on the screen of the operator terminal to detect the speed abnormality. can notify you. When a response command is input by the operator terminal that has checked the CCTV image, the processing unit 240 transmits a message requesting an on-site dispatch to the manager terminal 280 together with the CCTV image, while the current traffic volume by lane (traffic data use) Traffic safety information informing of the speed limit for each lane of the tunnel road calculated according to this method and the lane in which the vehicle is to be moved for lane control may be transmitted. Accordingly, the manager terminal 280 may take a corresponding action according to the traffic safety information to restore the vehicle speed to normal.

7A and 7B, when the next step ("3. SMS propagation") is input by the system operator who checked the CCTV image of the point where the abnormal symptom was detected on the screen 710, the processing unit 240 , it is possible to automatically generate a message requesting an on-site dispatch as shown on the right side of the screen 720, and transmit the message together with the CCTV image to the manager terminal 280 designated by the system operator.

At this time, the processing unit 240 searches the database 250 for traffic safety information corresponding to the abnormal symptom (eg, 'speed abnormality') and provides it to the manager terminal 280, so that the manager terminal 280 dispatched to the tunnel road It is possible to promptly implement appropriate countermeasures according to the above traffic safety information.

The database 250 is a countermeasure for preventing traffic accidents when an abnormality occurs on the tunnel road, at least one of vehicle speed limit, lane control, tunnel entry prohibition, detour recommendation, vehicle spacing, tire chain installation, and light lighting of traffic safety information is recorded for each of the above abnormal symptoms.

In addition, the database 250 may further record a priority determined based on the degree of risk for each anomaly. Accordingly, when a plurality of abnormal symptoms are detected, the processing unit 240 may take a situation notification and countermeasures in order according to a priority determined based on the degree of risk.

Hereinafter, the database 250 will be described with reference to FIG. 3 .

3 is a diagram illustrating a database in which traffic safety information for each abnormal symptom is recorded in the traffic safety management system on a tunnel road according to an embodiment of the present invention.

In the databases 250 and 310 of FIG. 3, abnormal symptoms ('EVENT_NAME') subdivided into 15 types through data analysis are recorded. In addition, in the databases 250 and 310 , traffic safety information ('Action', 'deceleration standard') on response measures for accident prevention is recorded in correspondence with each abnormal symptom.

The abnormal symptoms can be divided into abnormal symptoms related to traffic conditions, weather conditions, and tunnel conditions, and the abnormal symptoms related to the traffic conditions include 'speed abnormality' such as slowing down or overspeeding, and 'traffic volume' such as a sharp decrease or rapid increase in traffic volume. Anomalies can be exemplified, and abnormal signs related to weather conditions include 'freezing on the road' or 'slipping' due to rain or snowfall, 'snowfall stage 3' according to the amount of snow, 'strong wind stage 3', ' freezing forecast'.

As an example, when 'speed abnormal' or 'traffic abnormality' is detected on the tunnel road, the processing unit 240 refers to 'Action' in the databases 250 and 310, The same accident prevention activities can be carried out.

In addition, the processing unit 240 further refers to the 'deceleration criteria' in the databases 250 and 310, and guides the speed limit (maximum speed 60%) when 'strong wind stage 2' is detected on the tunnel road, and 'strong wind stage 3' is detected, traffic control is implemented, and when 'rainfall icing' or 'snow icing' is detected, countermeasures such as guiding the speed limit (50% maximum speed) can be implemented.

In addition, priorities ('1' to '15') determined for each anomaly are recorded in the databases 250 and 310 , and the processing unit 240 detects a plurality of anomalies, the higher priority anomaly. From there, it is possible to notify the situation and take countermeasures.

For reference, the databases 250 and 310 in this example are constructed based on the C-ITS service standard, referring to Article 19 Paragraph 2 of the Enforcement Rule of the Road Traffic Act and the results of the Incheon Bridge Advisory Council.

Hereinafter, with reference to FIG. 4, a process of detecting an abnormal symptom related to a traffic condition and implementing a countermeasure for accident prevention will be described.

4 is a flowchart illustrating a procedure for notifying a countermeasure when an abnormal symptom related to a traffic volume or an average driving speed is detected in the traffic safety management system on a tunnel road according to an embodiment of the present invention.

Referring to FIG. 4 , in step 401 , the sensing unit 220 determines whether a sudden drop in traffic volume is detected through analysis of traffic data acquired for each cycle, and in step 404 , the sensing unit 220 determines the cycle Through the analysis of the traffic data obtained every time, it is determined whether a sudden decrease in speed is detected.

When it is determined that a sudden drop in traffic volume is detected in step 401 or a sudden drop in speed is detected in step 404 , the output unit 230 detects abnormal symptoms related to traffic conditions in steps 402 and 405 . Notifies the operator terminal, and automatically displays the surrounding CCTV images taken before and after the occurrence of the abnormal symptoms in steps (402, 405).

In steps 406 to 408, the processing unit 240 inquires whether an on-site dispatch is required to the operator terminal that has checked the CCTV image, and when it is input that the on-site dispatch is required, SMS requesting an on-site dispatch to the terminal 280 of the tunnel person concerned It sends a message and responds by sending traffic safety information corresponding to anomalies.

As the countermeasure, the processing unit 240 may implement a VMS notification 410 related to lane control in order to prevent a sharp decrease in traffic volume or a decrease in speed.

As described above, the traffic safety management system 200 on the tunnel road analyzes the traffic data acquired from the vehicle traffic situation detection system 261, It can detect and deal with abnormal symptoms related to sudden surge, etc.).

In addition, the traffic safety management system 200 on the tunnel road through the analysis of the weather data acquired from the Meteorological Administration server 262 and the data acquired from various self-sensor facilities 263 installed on the tunnel road, Detects abnormal symptoms related to weather conditions that impair traffic safety (eg, strong wind, icing, etc.) or tunnel conditions (eg, fire, breakdown of street lights, etc.) and provides corresponding traffic safety information to the manager's terminal. Preventive countermeasures may be put in place.

As an example, the acquisition unit 210 acquires at least one weather data of rainfall, snowfall, temperature, wind speed and humidity from the Meteorological Agency server 262 and its own sensor facility 263 installed at the entrance and exit of the tunnel road, and , the sensing unit 220 detects an abnormal symptom ('second abnormal symptom') related to at least one weather condition of heavy rain, heavy snow, strong wind and freezing based on the acquired weather data, and the amount of rainfall in the weather data or When the amount of snowfall is equal to or greater than a certain amount and the temperature is below the freezing occurrence temperature, it is possible to predict and detect ice on the tunnel road.

The output unit 230 notifies the detection of the abnormal symptom to the operator terminal, and the processing unit 240, when a corresponding command is input by the operator terminal, provides traffic safety information corresponding to the abnormal symptom related to the weather condition. , may be retrieved from the database and transmitted to the manager terminal.

In this case, the traffic safety information may include a vehicle interval corresponding to the freezing of the tunnel road or a tire chain installation recommendation.

Here, the sensing unit 220 includes meteorological data (weather forecast) corresponding to the near future (eg, tomorrow, the day after tomorrow, one week, etc.) obtained from the Meteorological Agency server 262, and self-sensing facilities installed at the entrance and exit of the tunnel road ( 263), it is possible to accurately detect abnormal symptoms related to the weather condition by combining the current weather data (live weather conditions such as rainfall, snowfall, temperature, wind speed, etc.).

When the sensing unit 220 detects an abnormal symptom related to at least one weather condition among heavy rain, heavy snow, and strong wind for the tunnel road, the processing unit 240 corresponds to the abnormal symptom, limiting the vehicle speed, to the tunnel road. The traffic safety information indicating at least one of prohibition of entry, recommendation of a detour, and lighting of a light may be transmitted to the manager terminal 280 .

Hereinafter, with reference to FIG. 5, a process of detecting an abnormal symptom related to a meteorological condition and implementing a countermeasure to prevent an accident will be described.

FIG. 5 is a diagram illustrating a procedure of notifying a corresponding action for each strong wind step when an abnormal symptom related to a strong wind is detected in the traffic safety management system on a tunnel road according to an embodiment of the present invention.

5, when the weather data is obtained from the Meteorological Agency server 262 in steps 501, 502, and 504, the sensing unit 220 determines whether the current wind speed belongs to the strong wind restriction step 3 510. Detect and detect abnormalities.

That is, in steps 501 and 502 , when the current wind speed is less than 14 m/s, the sensing unit 220 determines that an abnormal symptom belonging to the strong wind restriction step 3 510 is not detected.

Meanwhile, in steps 501 and 502 , when the current wind speed is 14 m/s or more and less than 21 m/s, the sensing unit 220 determines that an abnormal symptom related to the first step of limiting the strong wind has been detected.

In this case, in step 503, the output unit 230 notifies the operator terminal of the detection of an abnormal symptom, and in step 504, the processing unit 240 prevents accidents by providing traffic safety information corresponding to the abnormal symptom. take countermeasures for For example, the processing unit 240 may generate a danger warning (high wind warning, maximum speed 30% deceleration, speed limit 50 km/h) through the VMS.

In addition, in steps 501 , 502 , and 504 , the sensing unit 220 determines that the current wind speed is 14 m/s or more and less than 25 m/s, an abnormal symptom related to the second step of limiting strong winds has been detected.
