Description

  The present invention relates to an accident processing progress display system and an accident processing progress display program, and in particular, a process for resuming train operation when an accident involving a transport failure (hereinafter, also simply referred to as “accident”) occurs. The present invention relates to an accident processing progress display system and an accident processing progress display program for visualizing the progress of the accident.

When an accident event occurs and the train operation is postponed, for example, a railway company employee (hereinafter also simply referred to as an “employee”) such as a station employee who is placed in a station and corresponds to the train user. Therefore, it is required to provide train users with as accurate information as possible about the current situation of accident response and recovery prospects.
In particular, the most important concern for train users is the expectation of when train operation will resume, and it is desirable to provide accurate information on this point.

Conventionally, when an accident occurs, information on the progress of accident handling is reported to the employee's transportation commander as needed, and the information gathered under the transport commander is communicated to the employee by voice as appropriate over the air. In general, employees provided information to train users based on this information.
As for the prospect of resuming operation, the processing time in past cases was taken into account, and the expected time to resume operation was derived from the employee's rule of thumb, and this was shown to train users.
Furthermore, in recent years, research is being carried out to automatically calculate the estimated time for train recovery (resumption of operation) in the event of an accident using a calculation formula. For example, Non-Patent Document 1 discloses an example in which prediction is performed using a Naive Bayes classification method.

"Research on Recovery Time Prediction in Railway Personal Accidents" IEICE Technical Committee Materials. TER, Transport and Electrical Railway Research Group 2007 (14), pp. 41-45, 2007.05.23

However, if the information gathered under the transportation commander is simply transmitted by voice, the employee may not be able to obtain the information if he / she misses it at the time of provision. In addition, there is a risk that the employee who is the listener may lack the accuracy of the information due to mistakes in the contents.
In this regard, it is also possible to input information collected under the transport commander and input it as text information to employees. Conventionally, this text information can only be seen by a specific person. In particular, employees who directly guide train users were not able to receive this text information.
For this reason, accurate operation information based on character information cannot be provided to train users, which may cause confusion.
In addition, it is difficult for employees to grasp the actual progress of accident processing with only raw text information, and station employees etc. provide accurate and accurate explanations to train users about the progress of accident processing and the prospects for recovery. I could not do it.

Furthermore, regarding the expected time (restoration time) for resuming train operation, when relying on the employee's empirical rules, the accuracy of the predicted time depends on human experience values and the like, and stable accuracy cannot be obtained.
In addition, the time from the occurrence of an event (accident), which is a major factor in the prediction of resumption of operation, to the arrival of related parties, the time from the arrival of related parties to the start of on-site investigation, etc. are continuous values. Therefore, as described in Non-Patent Document 1, in order to use the Naive Bayes classification method, a threshold value must be provided. When predicting the expected time to resume train operation using the Naive Bayes classification method, the accuracy of the prediction depends on how the threshold is set, but this threshold cannot always be set to an appropriate value.
For this reason, there is a problem that the accuracy and certainty are not so high even when the expected time (restoration time) for resuming train operation is predicted by this method.

  The present invention has been made in view of the circumstances as described above, and in the event of an accident, the accident processing progress that can provide employees and train users with as accurate and accurate information as possible about the resumption of operation.

[First Embodiment]
A first embodiment of an accident processing progress display system and an accident processing progress display program according to the present invention will be described with reference to FIGS. The embodiments described below are given various technically preferable limitations for carrying out the present invention, but the scope of the present invention is not limited to the following embodiments and illustrated examples.

FIG. 1 is a diagram showing an overall configuration of an accident processing progress display system 100 according to the present embodiment.
As shown in FIG. 1, the accident processing progress status display system 100 includes a processing status information server device 2 and a terminal device (in this embodiment, for employees) that performs display based on information provided from the processing status information server device 2. Terminal device 3).
The processing status information server device 2 is a network in which information stored in a processing status storage unit 21 and the like to be described later is mutually linked based on a protocol such as the Internet (TCP / IP, HTTP (Hyper Text Link Transformer Protocol). ) The information is provided to the employee terminal device 3 through N or the like as appropriate.

The processing status information server device 2 is connected to a program storage unit 20, a processing status storage unit 21, a specific information extraction unit 22, an expected time calculation unit 23, a progress status determination unit 24, a screen generation unit 25, an external device, and the like. Functional units such as an I / F 26 are provided, and these are connected by a bus 27.
Each functional unit will be described below.

The program storage unit 20 stores a program for each functional unit to perform various processes in the processing status information server device 2 that is a computer.
In the present embodiment, an accident processing progress display program for causing a computer to implement various functions for displaying an accident processing progress is stored in the program storage unit 20.

Further, in the present embodiment, the program storage unit 20 stores parameters for calculating the predicted value of the train operation resumption time and the operation resumption probability. The parameter is a logarithmic normal value representing the completion probability of each process (processing stage, in this embodiment, process A1 to process C as will be described later) used to calculate the predicted value of the operation restart time of the train and the operation restart probability described later. The average value μ of the required time in the distribution and the value of the standard deviation σ representing the degree of dispersion (see the items of process A1 to process C in FIG. 4), and the person A in the process up to restarting operation (process C described later) “Probability of changing the order of the on-site confirmation process” p.
These parameters are obtained in advance by analyzing past event (accident) cases. In order to improve the accuracy of the parameter, it is preferable that the number of events for obtaining the parameter is as large as possible. Further, it is preferable that this parameter is updated as needed. When a new event occurs, it is preferable to reflect the result of analyzing the case in the parameter as needed.

In addition, since the average value of the required time may vary greatly depending on the attribute such as the event occurrence category (accident occurrence location, etc.), when analyzing past events, the occurrence category etc. It is preferable to classify events according to the attributes and set a parameter for each attribute if there is a difference due to the attribute.
For example, if there is a large difference in the average time required for the event occurrence category (by location of the accident, etc.) due to the difference in the business form of the station, each process is subject to these three types of occurrence categories. Three types of parameters are prepared.
In addition, for the process up to resumption of operation (process C to be described later), different parameters are prepared for each case (C-1 and C-2 cases) on-site confirmation and on-site confirmation on-site confirmation according to the presence or absence of on-site confirmation. (See the process C item in FIG. 4).

The processing status storage unit 21 accumulates processing status related information, which is information related to the processing status at the event occurrence site, as character information as needed.
The processing status information server device 2 receives information such as processing status related information from an external device via the I / F 26 and stores the processing status related information in the processing status storage unit 21.
In the present embodiment, an event means an accident that occurs between train stations or between stations.
When an accident occurs, information such as the location and time of occurrence of the accident is reported to the transport command room by radio or the like. When the occurrence of an accident is reported, in the transport order room, the transport commander sends this information (that is, processing status related information) to the employee by radio etc. Etc.) and input processing is performed in the input terminal device 10. Then, the processing status related information is transmitted to the processing status information server device 2 as character information.

Information that is converted into text information as processing status related information widely includes information related to the processing status at the accident site. Specifically, for example, location information indicating the time when the accident occurred, the line where the accident occurred, and the accident site (if the accident occurred within the station, the relevant station, if the accident occurred between stations Where and between stations, etc.), arrival time of employees involved in train operation, contact time with related parties, arrival time of related parties, start time of evacuation activities outside the track Nearly 100 items of information such as the end time, presence / absence of on-site confirmation, weather at the time of the accident, etc. are included in the processing status related information.
In this embodiment, each line section, station, position information between stations is coded, and the processing status related information is a state in which the code indicating these is attached as information identifying the location where the accident occurred. Sent.
In addition, the input process which converts process status relevant information into character information is not limited to the case where the transport commander of the transport command room performs. For example, a person entrusted by the transport instruction room (for example, an outside contractor) may be in charge of input processing, and process status related information may be converted into character information and transmitted to the process status information server apparatus 2.

In the present embodiment, the processing status related information is weighted based on the degree of influence on the resumption of train operation, and the processing status storage unit 21 includes the processing status with the weighting information attached thereto. Related information is stored.
The weighting method is not particularly limited, and may be a value set based on the experience of the employee. In addition, the influence of each item included in the processing status related information on the restart of train operation may be analyzed from past event data, and objective weighting based on a plurality of past data may be performed. In this case, when a new event occurs, it is preferable to update the weighting value as needed by reflecting the analysis result of the case.

The specific information extraction unit 22 extracts specific stage related information related to the progress status of a predetermined processing stage (process) having a large influence on the restart of train operation from the processing status related information stored in the processing status storage unit 21. To do.
As described above, the processing status related information collected in the transport command room and transmitted to the processing status information server device 2 includes information of nearly 100 items. The accident processing progress display system 100 displays on the display means 30 the progress of accident processing for resuming train operation based on these processing status related information. Some of them have a major effect on the resumption of train operation after an accident, while others do not. When displaying the progress of an accident on the employee's terminal device 3 of an employee (station employee, etc.), displaying all of a wide variety of information makes it difficult to see the screen and makes it difficult to grasp the flow of accident processing. May cause confusion. For this reason, it is easier to understand and preferable to display the information on the terminal device 3 for employees with information necessary and sufficient for grasping the progress of the accident processing.
Therefore, in the present embodiment, a predetermined processing stage that greatly affects the restart of operation among the processing status related information stored in the processing status storage unit 21 is determined in advance, and the specific information extraction unit 22 performs the predetermined processing. Specific stage related information, which is information about the progress of the stage, is extracted from the processing status related information.

In the present embodiment, the specific information extraction unit 22 includes, as the specific stage related information, “arrival of the person in charge of the site on the spot”, “arrival of the party A on the spot”, “arrival of the party B on the spot”, “ Arrival of work vehicle on-site, completion of evacuation off track, completion of vehicle inspection, completion of on-site confirmation, completion of article search, resumption of partial operation, final safety confirmation, full operation Information relating to “resume” (that is, the time information) is extracted.
Note that the information extracted by the specific information extraction unit 22 is not limited to the information listed here. There may be fewer items than this, or information other than this may be included.

The expected time calculation unit 23 calculates the probability that the operation of the train is restarted (operation restart probability) based on the processing status related information stored in the processing status storage unit 21.
In this embodiment, the driving resumption probability is the driving at T when the elapsed time from the time of occurrence of the event (accident) (that is, “0”) to the present time is t ₀ and the time after the elapsed time t ₀ is T _0. Is the conditional probability that the operation is resumed within the elapsed time t from T ₀ when is not resumed.
Further, the expected time calculation unit 23 calculates a predicted value (expected time) of the train operation resumption time based on the processing status related information.
Note that, as described above, some of the processing status related information has a great influence on resumption of train operation after an accident, and some does not so much influence. In this respect, if items that have little influence are included in the items constituting the formulas for calculating the predicted values of the operation resumption probability and the operation resumption time, the number of samples decreases, and it is difficult to derive an accurate value.
Therefore, in the present embodiment, it is possible to obtain information such as time among the processing steps (hereinafter also referred to as “process”) from the occurrence of an event (accident) to resumption of operation (that is, Information stored in the processing status storage unit 21 as processing status-related information), and information on main processing stages (processes) that greatly affect the operation restart time in particular, and the expected time calculation unit 23 extracts The predicted value of the train operation resumption probability and the operation resumption time is calculated by applying the determined items to a predetermined formula.
The items to be officially applied may be items extracted by the specific information extraction unit 22, but in this embodiment, the items are further narrowed down to “location of occurrence of accident (occurrence classification)” “ “Arrival time at the site” “Arrival time of the related party A” “Arrival time of the related party B” “Evacuation completion time out of the track” “End time of on-site confirmation” “Resumption time of operation” To do. In addition, as a factor for dividing the flow of processing, “presence / absence of on-site confirmation” and “on-site confirmation method (that is, whether on-site confirmation is performed before or after other operations)” are considered.

FIG. 2 is an explanatory diagram schematically showing the position of each processing stage (process) extracted as an item to be officially applied in the present embodiment and the reference time of each required time in time series.
When an event (accident) occurs, the person in charge of the event receives the report of the event occurrence, first the person in charge of the field arrives at the site, then person A arrives at the site, and person B arrives at the site and goes off the track. Evacuation activities are conducted. Then, when the evacuation to the outside of the track is completed and the field confirmation is further performed, the operation of the train is resumed after this is completed.
In this embodiment, as shown in FIG. 2, the process until the arrival of the person in charge of the field is referred to as a process A1, the process until the arrival of the related person A is referred to as a process A2, and the process until the arrival of the related person B is referred to as a process A3. Further, the process B1 is the process up to the completion of the evacuation to the outside of the track, the process B2 is the process until the end of the on-site confirmation, and the process C is the process until the train operation is resumed.

The time required for each process and the reference time (“reference time” in FIG. 2) are as follows.
The time required for the process A1 (until the arrival of the site manager) is the time when the event occurrence time is the reference time (ie, “0”) and the time until the site manager arrives is expressed in minutes.
The time required for the process A2 (until the arrival of the related party A) is the time when the event occurrence time is the reference time (that is, “0”) and the time until the first related party A arrives is expressed in minutes.
The time required for the process A3 (until the arrival of the related party B) is the time when the event occurrence time is the reference time (that is, “0”) and the time until the related party B arrives is expressed in minutes.
In addition, the time required for the process B1 (until the evacuation to the outside of the line is completed) is the evacuation to the outside of the line with the time when the person in charge arrives (that is, the time when the process A1 is completed) as the reference time (that is, “0”) Is the time in minutes until the completion of.
The time required for the process B2 (until the end of the on-site confirmation) is set to the reference time (that is, “0”) when the party A first arrives (that is, when the process A2 is completed), and the on-site confirmation ends. Is the time in minutes.
The time required for Process C (until the train restarts) depends on whether or not the site is confirmed and the method of site confirmation. If there is no site confirmation or if the site confirmation is performed without stopping the train operation, The time when the two conditions of the arrival of the person B (that is, the completion of the process A3) and the completion of the evacuation outside the track (that is, the completion of the process B1) are both satisfied is set as the reference time (that is, “0”). This is the time in minutes before restarting. In addition, when the train operation is stopped and the site confirmation is performed and the train operation is resumed after the site confirmation is completed, the arrival of the person concerned B (that is, completion of the process A3) and the completion of the evacuation outside the track ( That is, the time when all three conditions of completion of the process B1 and completion of the on-site confirmation (that is, completion of the process B2) are satisfied is set as the reference time (that is, “0”), and the time until the operation is restarted in minutes Is the time required for process C.

Then, a state pattern that is a combination of processing stages (processes) theoretically considered as a state after t ₀ minutes from the occurrence of the event (accident) is created. That is, in each process of “A1”, “A2”, “A3”, “B1”, “B2”, and “C”, a combination pattern of the states “(process) completed” or “(process) incomplete” that is theoretically considered is created. To do. As a result, patterns of states 1 to 19 can be considered as the state patterns.
In the present embodiment, each of the items described above (ie, “location of occurrence of accident (occurrence classification)”, “arrival time of the person in charge of the site”, “arrival time of the person A in the field”, “site of the person B in the field” ”Arrival time at the road”, “time to complete evacuation off the track”, “end time of on-site confirmation”, “operation restart time”, “presence / absence of on-site confirmation” and “method of on-site confirmation”)) Formulas were calculated to calculate the predicted value of driving resumption probability and driving resumption time.

FIG. 3 shows the correspondence between variable names, variable types, and variable values in the formula of each item.
As shown in FIG. 3, the variable name of “event occurrence location (“ occurrence classification ”in FIG. 3)” is “k”, and the value of the variable is, for example, “1” to “1” depending on the event occurrence location. A value of “6” is assigned.
In addition, the variable name of “site manager arrival time” is “t _A1 ”, and the value of the variable is the elapsed time (minutes) since the event occurred. Similarly, the variable name of “related party A arrival time” is “t _A2 ”, the value of the variable is the elapsed time (minutes) from the occurrence of the event, and the variable name of “related party B arrival time” is “T _A3 ”, the value of the variable is the elapsed time (minutes) from the occurrence of the event, the variable name of “Evacuation completion time outside the track” is “t _B1 ”, and the value of the variable is , The elapsed time (minutes) from the occurrence of the event, the variable name of “site confirmation end time” is “t _B2 ”, and the value of the variable is the elapsed time (minutes) from the occurrence of the event, The variable name of “Resume time” is “t _C ”, and the value of the variable is the elapsed time (minutes) from the occurrence of the event.
Further, the variable name of “presence / absence confirmation” is “i ₁ ”, and the value of the variable is “1” when there is no field confirmation and “2” when there is field confirmation.
Furthermore, the variable name of “site confirmation method” is “i ₂ ”, and the value of the variable is “1” when the work method A is adopted as the field confirmation method, and when the work method B is adopted. Becomes “2”.
The variable type is an integer for all items.

FIG. 4 shows equations for calculating the probability density and cumulative probability for each processing stage (that is, “process A1”, “process A2”, “process A3”, “process B1”, “process B2”, and “process C”). It is.
FIGS. 5A and 5B show examples of graphs showing changes in probability density and cumulative probability over time.
Here, the probability density is the probability that each process is completed at time t, and the cumulative probability is the probability that each process is completed within time t.
As shown in FIG. 5A, the probability density f (t) has a peak when a predetermined time elapses from the processing start time. Further, as shown in FIG. 5B, the cumulative probability F (t) gradually increases as time elapses from the start of processing, and reaches 100% when a certain time elapses.

As described above, when an event actually occurs, each processing stage (process A1 to process C) is performed continuously, in parallel or selectively, and from the occurrence of an accident to the resumption of train operation. As the situation to be obtained (state pattern), the above-described states 1 to 19 are conceivable. Among these, since the operation of the train has already been resumed for the state 1, it is not necessary to calculate the predicted value of the operation resumption probability and the operation resumption time.
For this reason, in this embodiment, in order to calculate the predicted value of the operation resumption probability and the operation resumption time of the train, 18 formulas corresponding to the above states 2 to 19 are prepared, and the expected time calculation unit 23 first determines which of the above-mentioned state patterns the current state corresponds to, and assigns necessary items to the formulas prepared according to the respective state patterns to obtain the predicted values of the driving restart probability and the driving restart time. calculate.

図７は、運転再開時間の予測値E(X)、予測範囲の下限（minT）及び予測範囲の上限（maxT）をグラフ上に表したものである。
図７では、運転再開時間の予測値E(X)が１７時５０分であり、予測範囲の下限（minT）が１７時４０分であり、予測範囲の上限（maxT）が１８時１０分である場合を例示している。 Similarly, the upper limit maxT is a value that satisfies the following Expression 24.

... Formula 24

FIG. 7 is a graph showing the predicted value E (X) of the operation resumption time, the lower limit (minT) of the prediction range, and the upper limit (maxT) of the prediction range.
In FIG. 7, the predicted value E (X) of the operation resumption time is 17:50, the lower limit (minT) of the prediction range is 17:40, and the upper limit (maxT) of the prediction range is 18:10. A case is illustrated.

By using the above formula, the expected time calculation unit 23 predicts the train operation restart probability, the predicted value E (X) for the train operation restart time, and a prediction range having a certain range before and after that ( minT to maxT).
The calculation result by the expected time calculation unit 23 is stored in the processing status storage unit 21 or the like.

The progress status determination unit 24 determines the progress status of the accident processing until the train operation is resumed according to the processing status related information stored in the processing status storage unit 21.
As described above, in the present embodiment, the processing status related information stored in the processing status storage unit 21 is attached with weighting information set based on the magnitude of the degree of influence on resumption of train operation. Yes. The progress determination unit 24 determines the progress according to the weighted processing status related information.

Specifically, the progress degree determination unit 24 of the present embodiment determines how much the current process progress degree is about 100% when the train operation restart time is 100%.
For items that have a large influence on the resumption of train operation, even if one item is completed, the progress determination unit 24 determines that the progress has greatly progressed. On the contrary, for the items having a small influence on the restart of the train operation, even if a plurality of items are completed, the progress determination unit 24 determines that there is not much change in the progress.
For example, in the case of the accident handling process, the case where the weight for the item “Arrival of the related party A to the site” is twice as high as the weight for the item “the arrival of the related party B at the site”. Then, for example, when an accident occurs in the station premises of the XX line district, the arrival of the employee and the arrival of the related party B in the accident process are completed, but the related party A The process has been completed for two items when the employee has not arrived, the employee has arrived at the site, and the party A has arrived at the site, but the party B has not arrived. However, the progress determination unit 24 determines that the progress in the former case is lower than that in the latter (for example, the progress is determined as 8% in the former case). In the latter case, 15%, etc.)

In addition, the item which the progress condition determination part 24 uses for determination of a progress condition is not specifically limited. The determination may be made with reference to all of the processing status related information stored in the processing status storage unit 21. In the processing status related information, only predetermined items that influence the resumption of train operation are extracted. Reference may be made to make a determination. Further, the progress status determination unit 24 may determine the progress status with reference to the specific stage related information extracted by the specific information extraction unit 22.
The determination result by the progress determination unit 24 is stored in the processing status storage unit 21.
As the accident process progresses, the number of items that have been processed increases, and the progress of the accident process changes. For this reason, the progress status determination unit 24 performs determination processing based on the latest information as needed, and the determination result stored in the processing status storage unit 21 is updated when a new determination is made.

The screen generation unit 25 uses information stored in the processing status storage unit 21 such as processing status related information accumulated as character information, a calculation result by the expected time calculation unit 23, a determination result by the progress status determination unit 24, and the like. Image data constituting the display screen of the display means 30 of the employee terminal device 3 is generated.

In the present embodiment, the screen generation unit 25 is identified by the specific information extraction unit 22 as information related to a predetermined processing stage that greatly affects the restart of operation among the processing status related information stored in the processing status storage unit 21. Based on the stage-related information, image data constituting a display screen for displaying the progress of the accident process is generated.
Specifically, as the display related to the progress status of the accident process, the screen generation unit 25 first generates image data for progress status sequential display that sequentially displays a predetermined processing stage in time series.

The configuration of the progress status sequential display screen (see the progress status sequential display area 33 in FIG. 8) is not particularly limited. For example, when the processing is completed for a certain stage (step), the completed step is displayed on the display screen. Each time a new process is completed, the process item is displayed on the previously processed item. By displaying in this way, the lower part of the display screen is the item that has been processed earlier, and the upper part is the item that has been newly processed.
The items displayed as the progress status sequential display are items included in the specific stage related information extracted by the specific information extraction unit 22. All items included in the specific stage related information may be displayed, or only a part may be displayed.

In addition, the screen generation unit 25 generates image data for progress status enumeration display that enumerates and displays items related to the progress status of the predetermined processing stage as the display related to the progress status of the accident process.
The progress status enumeration display is to display various stages (steps) on the display screen as STEP information after the accident occurs until the train operation is resumed.
Similar to the progress status sequential display, items displayed as the progress status listing display are items included in the specific stage related information extracted by the specific information extraction unit 22. All items included in the specific stage related information may be displayed, or only a part may be displayed. The items displayed as the progress status display may be the same as the items displayed as the progress status display, or may be a smaller number of items.
In this embodiment, among the items included in the specific-stage related information, 10 items that have a significant effect on the resumption of train operation are selected (that is, “responsible arrival at the site” (STEP 1)) "Arrival" (STEP2), "Work vehicle arrival on site" (STEP3), ... "Final safety confirmation" (STEP9), "Full operation restart" (STEP10)) An example of enumeration display on the enumeration display screen (see the progress status enumeration display area 34 in FIG. 8) is shown.
Note that the STEP information listed here is an example, and other items may be included, or fewer items may be included.

Area 35). The screen generation unit 25 generates image data of a bar graph display screen based on the determination result of the progress determination unit 24.
In addition to the display showing the expected driving resumption time and the driving resumption probability, the image data of the display screen that displays basic information (accident occurrence location, type of accident, occurrence time, etc.) regarding the accident that occurred is also displayed on the screen. It is included in the image data generated by the generation unit 25.

The display of the display means 30 is controlled.
Further, the display control unit 31 controls the display of the display unit 30 so that the progress status sequential display region 33 is scroll-displayed by a touch operation.
Further, the display control means 31 displays a progress status enumeration display area 34 (see FIG. 8) for listing and displaying items related to the progress status of a predetermined process stage on the display means 30 as a display related to the progress status of the accident process. Based on the specific stage related information provided from the processing status information server device 2, the display of the display means 30 is controlled so as to switch the display of the progress status listing display area 34 so that the items for which processing has been completed are displayed in reverse video.
Further, the display control means 31 displays the progress degree display area 35 (see FIG. 8) for displaying the progress degree of the accident processing based on the determination result determined by the progress degree determination unit 24 so as to be displayed on the display means 30. The display of the means 30 is controlled.
Furthermore, the display control means 31 displays the expected time display area 32 (see FIG. 8) for displaying the predicted value of the train operation resumption time calculated by the expected time calculation unit 23 on the display means 30. Control the display of.
Further, the display control unit 31 displays the time having a predetermined width calculated by the expected time calculation unit 23 in the expected time display area 32.
Further, the display control means 31 displays the probability calculated by the expected time calculation unit 23 in the expected time display area 32.

FIG. 8 shows a case where the display screen of the expected operation resumption information based on the display image data generated by the screen generation unit 25 is displayed on the display unit 30 of the employee terminal device 3 under the control of the display control unit 31. It is the figure which showed the example of a display screen.
As shown in FIG. 8, basic information about the accident such as the location of the accident, the type of the accident, and the time of occurrence is displayed on the display screen of the expected operation resumption information.
The display means 30 also displays an estimated time display area 32 for displaying the predicted value of the train operation resumption time calculated by the expected time calculation unit 23 and the train operation resumption probability.
FIG. 8 shows an example of a display screen of expected driving resumption information when an accident occurs at 17:00 on the △ station on the XX line.
In the expected time display area 32, 17:50, which is the predicted value calculated by the expected time calculation unit 23, is displayed as the expected operation restart time. Further, in the expected time display area 32 of the present embodiment, the predicted range having a predetermined width calculated by the expected time calculation unit 23 and the probability that the operation of the train is resumed at a time within the range are displayed together. Is done.
In FIG. 8, the time from 17:40 to 18:10 is shown as the prediction range, and it is displayed that the probability that the operation of the train is resumed within this time is 80%.

The display means 30 displays a progress status sequential display area 33 for displaying predetermined processing steps in time series as a display relating to the progress status of the accident processing.
As shown in FIG. 8, in the progress status sequential display area 33 of the present embodiment, the oldest one in time series is displayed at the bottom, and when new processing is performed and the processing status related information is updated, the new status is displayed. The various processing steps (items) are displayed on the screen sequentially.
That is, for example, at 17: 5, a processing stage (item) “Employees are on the spot” is displayed, and then at 17:11, a new process of “A person in charge arrives at the site” is performed. When the processing status related information is updated, the processing stage (item) “the person in charge arrives at the site” is displayed on the item “the employee is facing the site”. Similarly, at 17:17, when a new process “Responsible person arrives at the site” is performed and the processing status related information is updated, “ A processing stage (item) “A related person arrives at the site” is displayed. Thus, the progress status sequential display area 33 always displays the latest item at the top. As a result, by looking at the progress status display area 33, it can be seen that in the latest status as of 17:17, it is in the stage where the parties concerned have arrived at the site.

In the present embodiment, the progress status sequential display area 33 is configured to be scroll-displayed by touching the display screen.
As time elapses, the processing stages (items) displayed in the progress status display area 33 increase, and when all items do not fit in the display screen, the oldest time (ie, progress status sequentially) The items disappeared from the display screen in order from the item displayed at the bottom of the display area 33. By touching the screen and scrolling, the old items disappeared from the display screen can be displayed again on the screen. .

The display means 30 displays a progress status enumeration display area 34 for enumerating and displaying items related to the progress status of a predetermined process stage as a display related to the progress status of the accident process.

Based on the specific stage related information provided from the processing status information server device 2, the display control means 31 switches the display of the progress status listing display area 34 so that the items for which processing has been completed are highlighted. .
In this case, the display color and the like are not particularly limited. For example, items that have not been processed may be displayed in white, items that have been processed may be displayed in gray or red, or items that have been processed may be displayed in shades.
In FIG. 8, the items “arrival of responsible person at the site” (STEP 1) and “arrival of related party at the site” (STEP 2), which have already been processed, are shaded, and other unprocessed items are outlined. The case where it is displayed is illustrated.

Further, a progress status display area 35 for displaying the progress status of the accident processing based on the determination result determined by the progress status determination section 24 is displayed on the display means 30.
In the present embodiment, as shown in FIG. 8, the progress status display area 35 is a bar graph showing the progress of processing at the current time when the train operation restart time is 100%. It is a thing. In the illustrated example, in addition to a bar graph display,% display by characters is displayed side by side.
The progress display area 35 may be anything that can intuitively inform the viewer of the display of the progress of the accident process, and the display method is not limited to the illustrated example. The display of the progress status display area 35 may be, for example, a pie chart display or a display in which the color changes as the progress status increases.

In addition, a “return button 36” for returning to the initial screen, an “information update button 37” for updating the display screen to the latest one, and the like are provided on the display screen of the display means 30. .
The contents displayed on the display means 30 and the layout of the display screen are not limited to the illustrated example.
In addition, the layout of the expected time display area 32, the progress status display area 33, the progress status listing display area 34, and the progress status display area 35, such as the layout and size, can be freely customized by the user of the employee terminal device 3. May be possible.

  Next, the operation of the accident processing progress display system in this embodiment will be described.

First, when an event (accident) occurs, the information is transmitted from the accident occurrence site to the transportation command room.
In addition to notifying the employees of the various places (eg station employees) of information such as the occurrence of the accident via voice communication, etc., the transportation ordering staff in the transportation order room uses the input terminal 10 to Process-related information such as the location of the occurrence and the time when the first report of the accident was notified is input and converted into text information. The processing status related information converted into character information is transmitted to the processing status information server device 2 as needed and stored in the processing status storage unit 21.
From the accident site, information on the progress of accident processing is transmitted to the transport command room at any time thereafter, and the processing status related information transmitted to the transport command room is input processed in the input terminal device 10 and converted into character information. It is transmitted to the processing status information server device 2 as needed and stored in the processing status storage unit 21 as needed.
At this time, the processing status related information is accompanied by weighting information based on the degree of influence on the resumption of train operation. This weighting process may be performed by a transport commander who performs input processing, or by prescribing a weighting value for each processing stage (process) by analyzing similar accident handling that occurred in the past. The specified weight may be automatically attached according to the processing stage (process). The weighted processing status related information is stored and accumulated in the processing status storage unit 21. The weighting process for the processing status related information may be automatically performed in the processing status information server device 2 after being transmitted to the processing status information server device 2.

The screen generation unit 25 generates a screen for displaying basic information such as the location and time of occurrence of an accident based on the processing status related information stored in the processing status storage unit 21, and the image generated by the screen generation unit 25 Data is distributed to each employee terminal device 3 via the Internet N.
In addition, when the accident processing is started and the processing status related information is accumulated in the processing status storage unit 21, the specific information extraction unit 22 performs predetermined processing that has a large influence on the resumption of train operation from the processing status related information. Specific stage related information about the stage progress is extracted.
Based on the specific stage related information extracted by the specific information extraction unit 22, the screen generation unit 25 causes the display unit 30 to display image data for displaying the progress status display area 33 and the progress status enumeration display area 34. Image data is generated, and the generated image data is sequentially transmitted to the terminal device 3 for staff.
Furthermore, the progress status determination unit 24 determines the progress status of the accident processing based on the weighted processing status related information. The determination by the progress condition determination unit 24 is repeatedly performed based on the latest information at any time. The screen generation unit 25 generates and generates image data for causing the display unit 30 to display a progress state display area 35 including a bar graph display and character information indicating a percentage based on the determination result by the progress state determination unit 24. The obtained image data is sequentially transmitted to the terminal device 3 for employees.
The display control unit 31 of the employee terminal device 3 causes the display unit 30 to appropriately display a display screen based on the latest information based on the information sent from the processing status information server device 2.

Further, the expected time calculation unit 23 calculates a predicted value of the operation resumption time of the train, the operation resumption probability, and the like based on the processing status related information stored in the processing status storage unit 21.
With reference to FIG. 9 and FIG. 10, calculation processing of the predicted value of the operation resumption time of the train and the operation resumption probability in the present embodiment will be described in detail.
FIG. 9 is a flowchart showing an overall flow of processing performed by the expected time calculation unit 23.
In FIG. 9, the expected time calculation unit 23 calculates the probability of restarting the operation at time t when the train operation has not been restarted after t ₀ minutes from the occurrence of the event (accident), and the predicted time for restarting operation. This shows the case of calculating (predicted value).
As shown in FIG. 9, the expected time calculation unit 23 first reads parameters for calculating a predicted value (step S1). If parameters are set for each event (accident) attribute, the parameter that matches the accident attribute is selected.
Next, various data (event data) related to the event (accident) that occurred and the current time t ₀ (ie, the elapsed time from the occurrence of the event (accident), in minutes), which is the time to predict the operation restart time Read (step S2).
Then, the expected time calculation unit 23 determines whether or not each of the processes A1 to C is finished. That is, it is determined whether the value of the input data for each process (tA1, tA2, tA3, tB1 , tB2, tC) and each process is compared with the current time t ₀ is completed (step S3).
Further, the estimated time calculation unit 23 determines the end state of each process, the presence / absence of on-site confirmation, and a method of on-site confirmation (that is, whether the operation is performed without stopping the train operation or the operation of the train is stopped). Referring to it, it is determined which of the state patterns (that is, state 1 to state 19) corresponds to the state after time t ₀ (step S4).

Here, the flow of the state determination processing (step S4 in FIG. 9) by the expected time calculation unit 23 will be specifically described with reference to FIG.
FIG. 10 is a flowchart showing a determination process as to which state pattern the state at each time point applies.

As shown in FIG. 10, when the process C is completed (step S <b> 11), it means that the operation of the train has already been resumed, and therefore state 1 in FIG. 10 (state 1 of the above-described state pattern). ), It is not necessary to predict the operation restart time. If the process C has not been completed, it is determined whether or not the process A3 has been completed (step S12). If the process A3 has been completed, the presence / absence (i ₁ ) of the on-site confirmation and the method ( i ₂ ) is determined (step S13). Here, when there is no information on the presence / absence confirmation (i ₁ ) and the method (i ₂ ), the expected time calculation unit 23 sets the parameter p (that is, the person concerned B does not confirm the field or operates the train. Judgment is made using the value of the probability p of performing on-site confirmation without stopping. If there is no on-site confirmation (i ₁ = 1) or the on-site confirmation is performed without stopping the train operation (i ₂ = 1), it is determined whether or not the process B1 is completed (step 1). S14) If the process B1 has been completed (step S11), it is determined that the state corresponds to the state 2 in FIG. On the other hand, when the process B1 has not ended, the expected time calculation unit 23 further determines whether or not the process A1 has ended (step S15), and when the process A1 has ended. Is in state 3 in FIG. 10, it is determined that it is in state 4 if it has not been completed.
In step S13, when there is a site confirmation (i ₁ = 2) and the train operation is stopped until the site confirmation is completed (i ₂ = 2), the expected time calculation unit 23 terminates the process B1. If the process B1 has been completed, it is further determined whether or not the process B2 has been completed (step S17). When the process B2 has been completed, it corresponds to the state 5 in FIG. 10, and when it has not been completed, it is determined to be the state 6.
On the other hand, if the process B1 has not ended in step S16, the expected time calculation unit 23 further determines whether or not the process B2 has ended (step S18), and the process B2 has ended. If yes, it is determined whether or not the process A1 is completed (step S19). When the process A1 has been completed, it corresponds to the state 7 in FIG. 10, and when it has not been completed, it is determined to be the state 8. On the other hand, if the process B2 has not ended in step S18, it is further determined whether or not the process A1 has ended (step S20). If the process A1 has been completed, it corresponds to the state 9 in FIG. 11, and if it has not ended, it is determined to correspond to the state 10.
If the process A3 has not ended in step S12, the expected time calculation unit 23 further determines whether or not the process B1 has ended (step S21), and if the process B1 has ended. Determines whether or not the process B2 is completed (step S22). When the process B2 is completed, it is determined that the process 11 is in the state 11 in FIG. On the other hand, if the process B2 has not ended in step S22, it is further determined whether or not the process A2 has ended (step S23). When the process A2 has been completed, it corresponds to the state 12 in FIG. 10, and when it has not been completed, it is determined to be the state 13.
If the process B1 has not ended in step S21, the expected time calculation unit 23 further determines whether or not the process B2 has ended (step S24), and if the process B2 has ended. Determines whether or not the process A1 is completed (step S25). When the process A1 is completed, it corresponds to the state 14 in FIG. 10, and when it is not completed, it is determined to correspond to the state 15.
On the other hand, if the process B2 has not ended in step S24, the expected time calculation unit 23 further determines whether or not the process A1 has ended (step S26), and if the process A1 has ended. Further, it is determined whether or not the process A2 is completed (step S27). If the process A2 has been completed, it corresponds to the state 16 in FIG. 10, and if it has not been completed, it is determined to be the state 17.
If the process A1 has not ended in step S26, the expected time calculation unit 23 further determines whether or not the process A2 has ended (step S28), and if the process A2 has ended. In the case of state 18 in FIG.

State pattern at the current time t ₀ (i.e., state 1 state 19) has been determined, estimated time calculation unit 23, an operation restart probability in this state (state 2 state 19 that are required for predicted value calculation) Calculate (step S5). When calculating the driving resumption probability, the above-described formulas (Formula 1 to Formula 18) prepared for states 2 to 19 are used.
Further, the expected time calculation unit 23 calculates a predicted value of the operation resumption time (step S6). At this time, in the present embodiment, the expected time calculation unit 23 uses the above-described formulas (Formula 19 to Formula 24), and the predicted value of the operation restart time (that is, the pinpoint time, for example, 17:50), A prediction range having a predetermined width (for example, 17:40 to 18:10) is calculated.

When the expected time calculation unit 23 calculates the predicted value of the operation restart time and the prediction range having a predetermined width, the screen generation unit 25 generates image data of a screen for displaying the calculation result, and the generated image Data is distributed to each employee terminal device 3 via the Internet N. Based on the distributed image data, the predicted value of the operation resumption time and the operation resumption probability are displayed in the expected time display area 32.
In addition, calculation of the predicted value of the operation resumption time and the operation resumption probability by the expected time calculation unit 23 is repeatedly performed at any time or every predetermined time interval until the operation of the train is resumed based on the latest information. Every time a new calculation result is obtained, new image data is generated, and the latest calculation result is displayed on the display means 30 of the employee terminal device 3 as needed.

As described above, according to the present embodiment, the following effects can be obtained.
That is, in this embodiment, processing status related information is accumulated at any time, and a display screen based on the processing status related information converted into character information can be displayed on the display means 30 of the employee terminal device 3. For this reason, when an accident or other event occurs, all employees can share accurate information about the progress of the accident process without fear of being missed or mistaken as in the case of voice communication. it can. For this reason, it becomes possible to provide train users with more accurate and detailed information than before.
Further, in the present embodiment, information transmission by voice is also performed in parallel, and information can be more reliably transmitted by diversifying means by which employees obtain information.

Further, from the processing status related information, only the specific stage related information having a large influence on the resumption of train operation is extracted, and only the predetermined processing stages (items) based on this information are displayed in the progress status sequential display area 33 and the progress status listing display. It is displayed in the area 34. For this reason, even when the terminal device 3 for employees is a small tablet terminal etc., required information can be displayed in an easy-to-understand manner.
Further, by making the progress sequential display area 33 and the progress status enumeration display area 34 narrow down to items that have a great influence on the resumption of train operation as described above, the employee can intuitively understand the progress of accident processing at the present time. Can understand.
The progress status sequential display area 33 is configured to be scroll-displayed by touching the display screen of the display means 30. For this reason, even when the display screen of the employee terminal device 3 is small, a plurality of processing stages (items) can be displayed.
