Description

  The present invention relates to a system for managing bus schedules such as buses, airplanes, and trains, and more particularly, to a bus schedule management apparatus and program for improving operability when the bus schedule is revised.

  Conventionally, in transportation organizations that operate transportation equipment such as buses, aircraft, and trains, operation schedules are created and transportation equipment is operated along the operation schedules. In addition, when operating a flight that is not on the existing schedule, such as temporary service, the existing schedule is added or modified. In recent years, when creating and managing an operation diagram, an operation diagram creation device and an operation diagram management device that are supported by computer resources are used to improve efficiency at the time of creation and operation. Hereinafter, a train operation will be described as an example.

  By the way, unlike sudden additions and modifications such as temporary trains, the regular train schedule undergoes significant revision work at an appropriate timing. In general, in the case of a significant timetable change due to such a schedule revision, the train schedule that has been used up to the previous day after the service date or the revision date is switched to a revised or revised train schedule. In other words, crews and station staff need to change their heads from the train schedule that has been used until now to the revised train schedule. Hereinafter, unless otherwise specified, “diamond revision” including addition and correction of information on the train schedule is described. In addition, the train schedule before the revision is described as “current train schedule”, and the train schedule after the revision is described as “modified train schedule”.

  Regarding the relationship between the current train schedule and the revised train schedule at the time of such a schedule revision, the assignment of crew members to trains that have been changed by comparing before and after the revision (hereinafter referred to as 'current revision comparison') The technique of reducing the confusion of a crew member by performing is disclosed (for example, refer patent document 1 and patent document 2). If there is no revision of the train schedule as a result of the current revision comparison, the contents of the current train data are copied to the contents of the revised train data, and crew members are assigned.

Japanese Patent Laid-Open No. 10-175550 JP 2002-264813 A

  Train schedules are easy to understand for humans if the amount of information is small. However, train schedules are very popular because of the recent overcrowded schedules and various types of trains such as "express", "express" and "normal". It's getting complicated. Therefore, not only do complex schedules have to be created when creating train schedules, but it is becoming more time-consuming to understand the train schedules obtained by crew members and station staff who actually use the completed train schedules. .

  On the other hand, diamond revisions are often made by making some changes based on the current train schedule. Even when a major revision is made on the whole, for example, the driving interval such as “Express”, “Express”, “Normal”, and the meeting station do not change so much, and the time is changed in minutes overall On the contrary, there are many cases where only the arrival number at a station is changed. In other words, from the point of view of the crew, it is not necessary to newly understand the configuration of the train diagram itself if it is a modified train diagram that changes only the time, the number of lines and the track to the current train diagram. By grasping only the changed matters, it may be possible to easily understand the train schedule.

  In addition, not only the time information but also the equipment information such as the station and the line district is simultaneously switched to the train schedule, so the crew and the station staff need to understand not only the time information but also the revision of the equipment information. This facility information also has a lot in common between the current train schedule and the revised train schedule, but the common information is not explicitly shown on the revised train schedule.

  However, the schedule revisions that have been performed as described above are based on the premise that the current train schedule and the revised train schedule are switched from the schedule revision date. Therefore, crew members and station staff cannot even know on the system which part of the revised train diagram is common with the current train diagram and where is not common. In this way, even if it is the contents of the schedule revision that can understand the revised train diagram more efficiently if it is originally, there is a problem that the crew and station staff have to understand the revised train diagram without knowing it is there.

  In addition, crew members and station staff use business forms apart from train schedules. For example, if it is a crew member, it is a portable timetable in which train information relating to its own crew section is recorded, and if it is a station staff member, it is a driving situation table in which information on trains to / from the station is recorded. These forms have to be revised along with the revision of the schedule, but in the past, the current train schedule and the revised train schedule have a common part and can be reused originally. For this reason, it was one of the factors that increased the work associated with the diamond revision.

  Furthermore, there is a problem that it is not possible to create a schedule that can be operated across the revised date because the current train schedule and the revised train schedule are switched from the revised date to the revised date. Therefore, even if there was a request to continually assemble in a form that spans multiple days, the current train schedule and the modified train schedule are created as separate train schedules, and both schedules are compared and revised. Separate schedules are created for the days before and after.

  As another problem, work to change equipment information such as stations and railway lines incorporated in the train schedule had to be done in accordance with the schedule revision, but in practice, the equipment information on the train schedule was changed. There was a request to do it from time to time.

  In this way, train schedules are (1) regularly and irregularly revised, (2) become more complex as the number of trains and equipment increases, and (3) train information (transportation equipment information) and equipment information Is often partly changed due to diamond revisions, and (4) train information and equipment information may be changed asynchronously, and it is a unique and difficult-to-handle information medium. It can be said that it has.

  The present invention is based on the problems as described above, and the first object thereof is to make it possible to express the difference between the current schedule and the revised schedule so that the crew and station staff can modify the schedule. It is an object of the present invention to provide an operation schedule management device and program that can make it easier to efficiently understand operation schedules or reduce the burden of revision work of forms accompanying the schedule revision.

  In addition, the second object of the present invention is to enable a schedule organization that operates across the schedule revision date, and even when it is desired to change the transport equipment information and the equipment information asynchronously, each can be changed at any timing. It is to provide an operation schedule management device and a program.

  The invention according to claim 1 for solving the above-mentioned problem is an apparatus for managing an operation schedule of a transportation system, and includes operation schedule information including expiration date information in one operation unit or one equipment unit. A schedule information storage means for storing the request information, and a user request management means for receiving the request information from the user and extracting the operation data requested by the user from the schedule information stored in the schedule information storage means The user request management means extracts operation diagram information for which the expiration date information is valid in the operation period when the information about the operation period of the operation diagram is included in the request information from the user. It is characterized by doing.

  Invention of Claim 2 for solving said subject is an apparatus for managing the operation schedule of a transport system, Comprising: Operation schedule information including expiration date information in one operation unit or one equipment unit A schedule information storage means for storing the schedule information, and an expiration date management means for monitoring the expiration date information in the schedule information stored in the schedule information storage means and extracting only the schedule information for which the expiration date is valid; When operating schedules in operation are displayed, operation data and the like are displayed based on the schedule information that the expiration date extracted by the expiration date management means is valid. .

  The invention according to claim 3 for solving the above-mentioned problem is the operation diagram management device according to claim 2, wherein the expiration date management means has an effective expiration date stored in the diagram information storage means. First operation schedule based on operation schedule information whose validity period is invalid and second operation diagram based on operation schedule information whose validity period is invalid are discriminated from certain operation schedule information and invalid operation schedule information. Are output on the same screen.

  A program according to a fourth aspect of the invention for solving the above-described problem is a program for causing a computer to execute the processing of each means according to the first aspect.

  A program according to a fifth aspect of the invention for solving the above-described problem is a program for causing a computer to execute the processing of each means according to the second aspect.

  According to the present invention, the operation schedule information is logically stored in one diagram information storage unit as operation schedule information including expiration date information in one operation unit or one facility unit. As a result, both the current schedule and the revised schedule are stored as data, and it becomes easy to select which schedule is extracted according to the user's request.

  Further, according to the present invention, operation schedules having different operation periods on the time axis such as past or future operation schedules can be compared and displayed. It will be a support for understanding, and if it is after the diamond revision, it will be possible to easily find the revised point by comparing with the operation schedule that has been used so far.

  Furthermore, according to the present invention, since the operation schedule information is stored as operation schedule information including expiration date information in one operation unit or one facility unit, it is possible to easily display the operation diagram according to the display purpose. Rather, the handling of the schedule of one operation unit operated across days becomes flexible.

  In addition, according to the present invention, since the operation schedule information is stored as operation schedule information including expiration date information in one operation unit or one facility unit, it is necessary to revise the transportation equipment and facilities at the same time. For example, when it is desired to change only the facility information, the change can be made at an arbitrary timing.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments to which the invention is applied will be described in detail with reference to the accompanying drawings. In this embodiment, a train schedule is described as an example. However, the present invention is not limited to a train, but can be applied to a bus, an aircraft, or the like that is used for operation management of transportation equipment and facilities using a service schedule.

  FIG. 1 is a diagram schematically showing the configuration of an operation schedule management device according to the first embodiment of the present invention. In FIG. 1, an operation schedule management apparatus 10 includes an expiration date management unit 11, a diagram information storage unit 12, a user request management unit 13, an output unit 14, an input unit 15, a network interface 16, and the like. The operation schedule management device 10 is configured by a computer such as a workstation or a personal computer. The output unit 14 is a device such as a CRT, LCD, or printer for printing, and the input unit 15 is a display. Devices such as a keyboard and mouse.

  The expiration date management unit 11 is one of the features of the present invention and functions on the memory of a computer. The diagram information storage unit 12 is a storage device such as a hard disk drive, and may be physically provided inside the operation diagram management device 10 or may be a storage device connected on the network 150. .

  FIG. 2 shows train information 120 related to the train schedule stored in the diagram information storage unit 12. The train information 120 is stored as one record for each train operated. FIG. 2 shows an example in which the train number 1001M is displayed. In the “Train number” column, the operation number of this train is recorded. In the “expiration date” column, use start date information and use end date information are recorded as the expiration date of the train schedule information of the train number 1001M. Details will be described later. In the “Station name” column, the names of the stations where the train with the train number 1001M arrives and departs are recorded in the order of the train's operation route, the arrival / departure / pass time at each station, the arrival / departure number and the name of the track on the way Etc. are described correspondingly.

  In general, one operation of a train schedule is defined in a unit called a streak. FIG. 3 is an example showing streak data (operation data) expressed based on the train information 120 of the train number 1001M stored in the diagram information storage unit 12 of the present invention, the horizontal axis indicates time, and the vertical axis Indicates a station. That is, a streak means a broken line when a train diagram is shown in the figure. In this example, the train with the train number 1001M leaves the station a at 21:00 and arrives at the station b at 22:00. After stopping for 1 hour at station b, it leaves station b at 23:00, passes station c at around 23:30, and arrives at station d at around midnight. At station d, it stops for 2 hours, departs around 2 am, arrives at station e at 3 am and ends its operation.

  The “expiration date” column in the train information 120 is a feature of the train schedule information in the present invention, and is information for determining the time when the line data defined in the train information 120 is adopted. In the case of the train number 1001M in FIG. 2, the expiration date is defined as “April 1, 2002 to March 31, 2004”. This is an example in which the use of the train schedule is scheduled to start from April 1, 2004, and the operation of the train with the train number 1001M is scheduled to be abolished at that timing.

  The expiration date management unit 11 manages the expiration date based on information recorded in the train information 120 stored in the diagram information storage unit 12. The expiration date management unit 11 always monitors the expiration date of each line data recorded in the train information 120, and invalidates the line data that has reached the expiration date on the operation schedule on the next business day. However, the information is not immediately deleted from the diagram information storage unit 12. For example, when the schedule revision is scheduled on April 1, 2004 as described above, the fact that the next schedule revision is April 1, 2004 is registered in the schedule information storage unit 12 or the like. The expiry date management unit 11 invalidates the train number 1001M that has expired on the registered schedule revision date, for example, by not displaying it on the next day's schedule.

  Regardless of the schedule revision, the expiry date is also managed for temporary trains whose expiry date is defined as “March 1, 2004 to March 20, 2004”. Even if it passes, information is not deleted from the diagram information storage unit 12 immediately. Further, in the case of a train that continues to operate even after the schedule revision, the date or code indicating infinity or the like is stored as the end date of the expiration date.

  As described above, the present invention is characterized in that the current train diagram and the modified train diagram are treated as one operation diagram. In other words, in the past, the current train schedule and the modified train schedule were switched across the revision date. However, in this application, the data is logically stored in one diagram information storage unit 12 and there is a difference in operation. Is to manage the expiration date. Therefore, both the current train schedule and the modified train schedule are stored as data, and it becomes easy to select which train schedule is extracted according to the user's request.

  The user request management unit 13 in the operation diagram management device 10 has a function of classifying requests from users input via the input unit 15 or the network 150 and performing processing such as train schedule extraction. For example, when the schedule revision date is April 1, 2004, a crew member who is a user may want to compare and display the current train schedule and the revised train schedule. In such a case, a range to be compared is set with an arbitrary option such as “route name”, “time zone”, “section”, and “train number”, and a search request is made to the train diagram management apparatus 10. Hereinafter, an example of a train diagram display according to a user request will be described with reference to a flowchart 200 of FIG.

  For example, when the line data as shown in FIG. 3 of the currently operated train diagram or other information is displayed on the screen of the computer used by the user, the user can display past or future train diagram information. When it is desired to know, an arbitrary item such as “route name”, “time zone”, “section”, “train number”, “train type”, and “output format” is designated and input / transmitted as request data. This request data is received by the user request management unit 13 in the operation diagram management device 10 (step 201).

  With respect to the received request data, the user request management unit 13 analyzes the contents of items designated by the user, such as “route name”, “time zone”, “section”, “train number”, and “train type” (step 202). The analysis referred to here is preprocessing for performing a search in the next step 203, such as whether the designated item is an AND condition. Subsequently, search processing is performed on the diagram information storage unit 12 based on the result of user request data analysis (step 203). This search process is performed in the same manner as a general database search.

  When the search result in step 203 is obtained, the user request management unit 13 outputs the search result in the “output format” desired by the user received as the request data (step 204). There are various output formats. For example, the current train diagram and the modified train diagram can be displayed side by side on the same screen, or only the difference between the current train diagram and the modified train diagram can be displayed.

  In this way, the expiration date information is provided for each train information 120 (strip data), and the expiration date management unit 11 performs the expiration date management, so that crew members and station staff who are users can see the range of their own. The line data you want to see can be specified and displayed in comparison with past or future train schedules. If it is before the schedule revision, it will be helpful to understand the train schedule after the revision date in advance, and if it is after the schedule revision, it will be easy to find the revised point by comparison with the current train schedule that has been used to date I was able to help. In particular, line data that has not been changed at all between the current train schedule and the revised train schedule can be confirmed at a glance.

  In this example, the train with the train number 1001M was abolished on March 31, 2004. For example, the train number does not change, but some trains after April 1, 2004 There are cases where only the arrival and departure times at the station change. In such a case, the train information 120 of the same train number 1001M whose start date information of the expiration date is April 1, 2004 is duplicated with the train information 120 of the train number 1001M shown in FIG. Stored in the storage unit 12. That is, the train information 120 having the same train number is configured to exist in the diagram information storage unit 12 as a plurality of records. Each train information 120 is recorded with a record-specific ID (not shown) so that each train information 120 can be distinguished.

  For example, in the above step 204, when the user requests to display the current train schedule and the revised train schedule side by side on the same screen for a train whose only departure time is revised, it can be displayed as shown in FIG. The line data displayed in the upper part of FIG. 5 is the same as that of FIG. 3, and the lower part is a train diagram of the same train number 1001M after the schedule revision dated April 1, 2004. Since comparison display is possible in this way, the train with the train number 1001M can be confirmed at a glance that the schedule after 1:30 is changed before and after the schedule revision.

  In FIG. 5, only the train number 1001M is displayed to simplify the description. However, for example, the line data of another train number operated in the same time zone may be displayed at the same time.

  Next, an example in which an expiration date is set in the facility information will be described. FIG. 6 shows the facility information 130 stored in the diagram information storage unit 12. In the facility information 130, information on the station and the line district is stored as one record for each facility. One equipment unit means one unit of equipment related to train operation, for example, a station or a line number. In FIG. 6, it is the example displayed about aaaa station. In the “station number” column, the aaa station ID number “20050” is recorded. In the “expiration date” column, use start date information and use end date information are recorded as the expiration date of the facility information of this aaa station. In the “station name” column, the official station name “aaaa” of this aaaa station is recorded. In the “portable timetable station name” column, a station name “aa” when a short time display is desired in a station name description space such as a small timetable carried by a crew member is recorded. Record any data related to other equipment.

  The handling of the expiration date is processed in the same manner as the train information 120 described above. For example, if the station name is changed from “aaaa” to “aaab” on an arbitrary date and the mobile timetable station name is changed from “aa” to “ab” accordingly, the facility information 130 of the station number “20050” is changed. Two records before and after the station name change are set, and an expiration date is set according to the change date. By doing in this way, when displaying the diamond on the day arbitrarily designated by the user, “aaa” is displayed when the diamond before the station name change of aaa station is displayed, and “aaab” is displayed when the diamond after changing the station name is displayed. It is possible to prevent confusion, and the data of the portable timetable can automatically change only the station name of aaaa station, so that the business efficiency can be dramatically improved.

  The expiration date of the facility information 130 will be described in more detail. FIG. 7 shows an example in which information relating to the station number line is recorded as the facility information 130, one record for each number line (in FIG. 7, one column of the table indicates one record). Is recorded.

  In FIG. 7, the same station number “20050” is shown in the “station number” column on the first line of each record, and it is shown that three records are the same station number information. The “station number” column is linked to the “station number” column of the facility information 130 for each station, and both pieces of facility information 130 are stored in association with each other.

  The second line in FIG. 7 is a “station name” column, and an official station name is displayed based on the link. The third line in FIG. 7 is a “number line number” field, the fourth line is a “number line name”, the “number line number” is an ID code similar to the “train number” or “station number”, and the “number line name” is The actual line display is recorded. The third line of this station is not currently used, but it is scheduled to start on April 1, 2004. Therefore, in the fifth line of “number name” ‘(3)’ in FIG. 7, the use start date is set to April 1, 2004. Therefore, after this date, use of a new number line can be started.

  As described above, the facility information 130 is created in an arbitrary unit, such as a station unit or a line unit, and the expiration date is managed in the same manner as the train information 120 by giving each the expiration date, It is not necessary to exchange data all at once on the date of revision, and it is possible to realize a diamond display that flexibly responds to requests from crews and the like.

  Next, a second embodiment of the present invention will be described. The operation diagram management device in the second embodiment performs substantially the same processing as the operation diagram management device in the first embodiment, but the format of data recorded in the diagram information storage unit 12 is different. Therefore, in the present embodiment, only parts different from the first embodiment will be described.

  FIG. 8 is a diagram in which timetable information is added to the line data of the train number 1001M in FIG. Some companies set 24 hours from midnight as one business day as a business unit in a shipping company, and sometimes 24 hours from 1:00 a day as one business unit. Therefore, the expiration date management unit 11 can perform the expiration date management based on one business unit date stored in the diagram information storage unit 12 or the like. For example, in the line data shown in FIG. 6, it is assumed that one business unit day is 24 hours from 1 am. And it demonstrates as a case where a train schedule is operated from April 1, 2004.

  In this embodiment, since one business unit day is switched at 1 am, the train with the train number 1001M in FIG. 8 is actually 1 am on April 1, 2004 as the operation on March 31, 2004. After that, it is necessary to be treated as train number 100A on April 1, 2004 of the revised train diagram. In order to make this possible, in this embodiment, train station information 140 for each station is stored in the diagram information storage unit 12 for each train. In the train information 120 of the first embodiment, information of all stations where the train arrives and passes is recorded for one train number. However, in this embodiment, the train information 120 Recording is performed as one record for each station (equipment).

  As shown in FIG. 9, the train station information 140 includes items such as “train number”, “expiration date”, “station number”, “station name”, “number line”, “arrival time”, and “departure time”. In FIG. 9, one column corresponds to one record.

  This train station information 140 also has an expiration date. In FIG. 9, there are two records with a train number “1001M” and a station number “20053”. One record is “April 1, 2002- “March 31, 2004” is set to “April 1, 2004-∞”. In this example, the current train schedule information is invalidated in accordance with the schedule revision of the DDDD station on April 1, 2004.

  If we look at the train number 1001M that runs across the schedule revision date in chronological order in FIG. 8, the train that departed from aaaa station at 9:00 pm on March 31, 2004 will be the bbbb station at 22:00. And stop for 1 hour. After that, the bbbb station departs at 23:00 and arrives at dddd station at midnight. Since the business unit day changes at 1 am on April 1, 2004, 1 hour after arriving at the dddd station, the train schedule will be adopted.

  In other words, in the record of the station number “20053” of the train number “1001M” that has expired under the current train schedule, the dddd station departed at 2 am, but the train number that is valid under the revised train schedule In the record of “1001M” station number “20053”, the dddd station is set to depart at 1:30 am. Therefore, the train is located at 1:30 am based on the changed train schedule. You can leave.

  If the train number 1001M that departed from aaaa station at 9:00 pm on March 31, 2004 and wants to use the current train schedule until the final station, the expiry date will be one day ahead of March 30, 2004. It can respond by setting it as a day. Alternatively, for a train that operates across days, data indicating that the day has been crossed may be stored in the train station information 140 so that it can be understood that the train has been operated across days. By performing such processing, the train that has started from the first station on the current train diagram is operated to the last station on the current train diagram. And after the revision date, the train station information 140 that is effective in the train schedule is adopted.

  In this way, as a method of extracting train station information, when only train information of a specific station on April 1, 2004 is extracted, it has been operating across business days. It is possible to create a list excluding trains operated based on the current train schedule up to March 31, 2004 the previous day.

  As described above, in the second embodiment of the present invention, the train station information 140 is recorded as one record for each station (equipment) of one train number, more finely than the first embodiment. Moreover, since the train station information 140 has an expiration date for each record, it is not necessary to switch train diagram information all at once due to a schedule revision or the like. In other words, it becomes possible to change the operation status of the train and equipment at completely different timings. Therefore, it is possible to create train schedule information so that the train can be operated so as to straddle days such as schedule revisions and equipment changes.

  In the above embodiment, an example in which the expiration date is performed in units of days has been shown, but the present invention is not limited to this, and it may be set up to units of time. Moreover, in the description of the train information 120, the facility information 130, and the train station information 140, only representative items are described, but the items of each information are not limited to this.

  In addition, the data train information 120, the facility information 130, and the train station information 140 whose expiry date has passed are stored in the diagram information storage unit 12 until the time when the organization that uses this apparatus arbitrarily determines it, and is no longer necessary. Sometimes it can be deleted.

  As described above, the operation schedule management device according to the present invention is configured so that the expiration date information is set in the facility information unit such as the train information and the station stored in the diagram information storage unit 12, so that As a result, it is possible to store the timetables at the same time, and it is possible to arbitrarily specify and output the train timetable information at the time point desired by the crew or maintenance personnel who are users.

  In particular, trains that run only at a specific time, such as temporary trains, can be added to the train schedule and activated only during that period. It is very easy to use for crew and station staff.

  The embodiment described above can be realized by a computer executing a program. The means for supplying the program to the computer may be a computer-readable recording medium such as a CD-ROM recording the program or a transmission medium such as the Internet for transmitting the program. As mentioned above, although embodiment of this invention has been explained in full detail with reference to drawings, a concrete structure is not restricted to said embodiment, In the range which does not deviate from the summary of this invention, it can change suitably.

  As described above, in the operation diagram management apparatus of the present invention, operation diagram information logically stores operation diagram information including expiration date information in one operation unit or one facility unit in one diagram information storage unit. By doing so, both the current schedule and the revised schedule are stored as data, and it becomes easy to select which schedule is to be extracted according to the user's request. Therefore, the bus schedule management device of the present invention can be applied to a system for managing bus schedules such as buses, airplanes, and trains.
