Description

  The present invention relates to a train operation simulation method and a train operation management device, and in particular, a train operation simulation method for simulating a train operation state with a crossing opening time as an evaluation target, and a train operation management using the simulation method. Relates to the device.

In rail traffic, various proposals have been made for the purpose of improving the opening time of a railroad crossing for an “opening railroad crossing” that has an extremely short opening time.
For example, on-road information such as brake performance and train speed information is transmitted to the level crossing safety device on the ground to properly control the level crossing on the ground side (for example, see Patent Document 1), There is a method of controlling a railroad crossing by distinguishing the passage / stop of a train station depending on the type of train.

In addition, as a countermeasure for “crossing without opening”, a method of increasing the opening time of a railroad crossing by controlling train operation while paying attention to one crossing is considered. For example, if the level crossing is controlled to be closed continuously because the preceding train and the following train are approaching each other and the closing time of the level crossing becomes long, the speed limit is applied to the following train and the level crossing control is performed. How to delay the approach to the section so that the closing time of the level crossing does not become long, or when a train in the opposite direction tries to enter the level crossing control section before one train exits the level crossing control section in the double track section There is a method of opening the railroad crossing by delaying the approach to the railroad crossing control section in the opposite direction.
Japanese Patent Laid-Open No. 10-6994

  However, the conventional measures aimed at improving the opening time of a level crossing are only methods for devising control by paying attention to individual level crossings, and do not consider the level crossing of the entire train operation section. The above-mentioned “crossing without opening” measure is also intended for one level crossing, and there is no guarantee that the same control can be performed for all level crossings installed in the train operation section. In addition, if it is controlled, there is a possibility that a train that must originally travel on the street may not be able to travel on the street, so that the punctuality of the train cannot be ensured.

  The present invention has been made paying attention to the above problems, and it is possible to improve the opening time of a railroad crossing in consideration of the railroad crossing of the entire train operating section, and to simulate train operation that can ensure the punctuality of the train. It aims to provide a method. Moreover, it aims at providing the train operation management apparatus which manages the operation of a train based on the simulation result.

For this reason, the train operation simulation method according to the first aspect of the present invention artificially changes the operation management elements related to the train operation management with a preset change pattern, so that the railroad crossing existing in the train operation section is changed. A change in opening time is simulated, and an evaluation target of the simulation result is a total value of opening times of all level crossings in the train operation section .

According to this method, the operation management elements related to the train operation management are changed in a pseudo manner with a preset change pattern, and the change in the opening time of the level crossing existing in the train operation section is simulated. By making the evaluation result of the train result the total value of the opening times of all the railroad crossings in the train operation section, it becomes possible to increase the opening time of the railroad crossing in consideration of the crossing of the entire train operation section. In addition, in the double track section, the operation status of the trains on the upper and lower lines can be reflected in the simulation result of the change in the level crossing opening time, so that the effect of improving the level crossing opening time can be enhanced.

As claim 2, the traffic control elements, the train departure time of the station in the train schedule of service interval, arrival time, and have good if at least one is of the inter-station running pattern.

The train operation management device according to claim 3 of the present invention includes operation management information input means for inputting operation management information including operation management elements related to operation management of trains, and storage means for storing the input operation management information. And a change in the opening time of a railroad crossing existing in the operation section of the train based on the operation management information stored in the storage means using the train operation simulation method according to claim 1 or 2 . And a train operation plan creating device for creating a train operation plan so as to increase a crossing opening time from the simulation result of the simulation device, and managing the operation of the train based on the train operation plan It was set as the structure to do.

It said simulating means, as claimed in claim 4, a configuration to simulate by using at least one of information of train schedule information and the inter-station running pattern information of the traffic control information.
As in claim 5, the operation plan creation means may be configured to create a train schedule.

  As described above, according to the train operation simulation method of the present invention, it is possible to increase the level crossing opening time in consideration of all level crossings existing in the train operating section, Improvement effect is obtained. Moreover, since it is possible to consider the operation of trains on the upper and lower lines in the double track section, the effect of improving the level crossing opening time can be obtained. Furthermore, since the train can be managed in accordance with the train schedule, it is possible to ensure the punctuality of the train.

  Moreover, according to the train operation management apparatus of the present invention, it is possible to manage the operation of a train that increases the opening time of a railroad crossing while ensuring the punctuality of the train.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a schematic configuration diagram of an embodiment of a simulation apparatus used in a train operation simulation method according to the present invention.
In FIG. 1, the simulation apparatus 1 of the present embodiment includes an input unit 2, a line section information memory 3, a train diagram memory 4, a run curve memory 5, a control unit 6, and a display device 7.

  The input unit 2 is for inputting operation management information and simulation conditions of a train operation section to be simulated. As the operation management information, a train schedule, line section information of a train operation section to be simulated, run curve information defining a travel pattern between stations, and the like are input. As a simulation condition, a preset change pattern of an operation management element included in the operation management information and related to the operation management of the train in the train operation section is input. As the operation management element to be changed as a simulation condition, for example, run curve information of a station departure time, a station arrival time, or an inter-station travel pattern in the train schedule can be considered. Moreover, you may make it simulate by changing two or all of these.

The line area information memory 3 stores the line area information input from the input unit 2, and includes, for example, the distance between stations in a train operation section, position information such as a level crossing, a level crossing controller, and a curve section. Information is stored.
The train diagram memory 4 stores a train diagram input from the input unit 2.
The run curve memory 5 stores run curve information input from the input unit 2.

The control unit 6 stores and saves the train schedule, line section information, and run curve information input from the input unit 2 in the memories 3 to 5. Moreover, according to the simulation conditions input from the input unit 2, the train operation described below is executed using the line section information, the train diagram, and the run curve information in each of the memories 3 to 5, and the train operation is performed. A change in the opening time of the level crossing in the section is calculated, and a simulation result of a predetermined evaluation target is output based on the calculation result.
The display unit 7 displays the simulation result of the control unit 6.

Next, the train operation simulation method of this embodiment will be described.
The concept of crossing control of a railroad crossing when simulating train operation in this embodiment will be described.
As shown in FIG. 2, railroad crossing controllers B1 and B2 are installed on the front side and the front side of the railroad crossing with respect to the traveling direction of the train A (the arrow direction in the figure). When the train A passes through the foreground crossing controller B1, the crossing barrier C starts to close, and then the train A passes through the crossing, and further, when the train A passes through the front crossing controller B2, the crossing barrier C starts to open. Assuming that the section between the foreground level crossing control B1 and the front level crossing controller B2 is a level crossing control section, the level crossing is as shown in the timing chart of FIG. 2 until the train A enters the level crossing control section and then exits. Closed state.

  In the case of a double track section, as shown in the timing chart of FIG. 3, for example, before the descending train passes the front level crossing control B2 of the level crossing (the level crossing breaker C is in the closed state), the upstream train is at the level crossing before the level crossing. When the control element B1 is passed, the level crossing breaker C is continuously closed and the level crossing is closed during that time.

The simulation method of this embodiment simulates a change in the level crossing opening time in the level crossing opening / closing control described above when the station departure time of each train in the train diagram is changed minutely.
For example, as shown in FIG. 4, the station departure time of the train diagram input in advance is changed with a change pattern set in advance with respect to the reference stripe (indicated by a solid line in the figure). FIG. 4 shows a case in which the departure time is changed by -5 seconds with respect to the reference stripe (when the departure time is advanced by 5 seconds as in the left dotted line in the figure) and a case in which the departure time is changed by +5 seconds (as in the right dotted line in the figure). In the case where the departure time is delayed by 5 seconds).

  In this way, when the train departure time is changed, if the traveling patterns between the stations are the same, the opening / closing timing of the railroad crossing, in other words, the passing timing (passing time) of the railroad crossing controllers B1 and B2 is the reference line. Compared with the case where the train schedule is operated, the opening time of the railroad crossing changes as a result of changing the departure time of the station. FIG. 5 shows an example of changing the station departure time of the down train by +5 seconds without changing the time of the up train in the double track section, and the closing time of the railroad crossing by the upper and lower trains is shown by a dotted line in the figure. Totally decreases by 5 seconds. In other words, the crossing opening time is increased by 5 seconds.

  In this way, the departure time at all stations of all trains in the train schedule in the train operation section is changed with a preset change pattern to simulate the train operation, and the change in the level crossing opening time is simulated. The simulated train schedule is evaluated based on the simulation result of the opening time. The change pattern may be a change pattern that is changed with a time interval such as {-15, -10, -5, 0, +5, +10, +15} seconds, or {-5, It may be a change pattern that changes at continuous values such as −4, −3, −2, −1, 0, +1, +2, +3, +4, +5} seconds.

Next, a simulation result evaluation method will be described.
Railroad crossing k (k = 1,...) From time T1 to T2 that is input from the input unit 2 and stored in the train timetable memory 3 when the train timetable is set without considering the leveling time. , N) Let Pk be the track occupation ratio and Qk be the road occupation ratio of the crossing k. Here, the track occupancy rate Pk indicates the rate at which the crossing is closed and the train is in a passable state, and the road occupancy rate Qk indicates the rate at which the crossing is open and the road side is in a passable state. Therefore, Pk + Qk = 1. For example, when Pk = 0.5, Qk = 0.5, indicating that the track and the road occupy the railroad crossing k, and when Pk = 0.75, Qk = 0.25, Expresses that the track and road occupy the railroad crossing k at a ratio of 0.75: 0.25 = 3: 1. In the latter case, the railroad crossing is closed for 3/4 of the time period from time T1 to T2. Will be.
K indicates the number of a crossing existing in the train operation section to be simulated, and indicates that n crossings exist in the train operation section.
Assuming that the change pattern related to the station departure time is m, the number of stations is 1, the number of trains is i1 up, and i2 down, the total number of combinations is m ^{(l-1) i1 xm (l-1 ) i2} = m ^{(l-1) (i1 + i2)} , and if the number of combinations is enormous, instead of evaluating all the combinations, use a genetic algorithm etc. to evaluate some combinations It may be.

Next, with reference to the track occupancy Pk and road occupancy Qk, simulated results of the evaluation, the case where the opening sum of time of all crossing train operation interval, the evaluation function as follows Set.

When the evaluation result of the simulation result is the total value of the opening times of all the level crossings in the train operation section, the evaluation function Ek for each level crossing k is set as shown in the following equation (1).
When Pk−Qk ≦ 0, Ek = 0
When Pk−Qk> 0, Ek = Pk−Qk (1)
Pk−Qk ≦ 0 indicates a state in which the road occupancy is satisfied, which means that it is not necessary to increase the level crossing opening time, and Ek = 0 is excluded from consideration. On the other hand, Pk−Qk> 0 indicates that the road occupancy is not satisfied and means that the level crossing opening time needs to be increased. Ek = Pk−Qk is set as an object to be considered. Calculate the difference.

And the evaluation function E of the level crossing opening time of the whole train operation section is set like the following (2) Formula.
E = E1 + E2 +... + En (2)
Therefore, the larger the value of the evaluation function E, the higher the track occupancy rate Pk in the entire train operation section, which means that it is necessary to increase the opening time of the level crossing.

  Using the evaluation function E as a reference value, as described above, for example, the evaluation function E ′ when the station departure time is changed with the preset change pattern as described above is calculated, and the reference evaluation function E and Compare. If E ′ <E, it can be seen that the operation simulation in which the evaluation function E ′ is obtained has an effect of increasing the level crossing opening time. Incidentally, it goes without saying that if the train diagram of the operation simulation with the smallest evaluation function E ′ is employed, the time required for opening the level crossing is maximized.

  In this way, all train crossings in the train operation section are taken into account by simulating train operation by minutely changing the departure time of each train in the train diagram and simulating the change in the level crossing opening time at that time. Thus, it is possible to increase the opening time of the level crossing. In addition, since the train operation status of the upper and lower lines will be taken into consideration, the effect of improving the level crossing opening time is great.

  In the above-described embodiment, an example of simulating by changing the station departure time of each train with the same traveling pattern between stations has been described. It is also possible to simulate the train operation by changing the pattern to simulate the change in the level crossing opening time. Conversely, the train operation may be simulated by slightly changing the passing time of the railroad crossing controller. In this case, in order not to change the station departure time, the travel pattern may be variably set based on the line section information between the station and the railroad crossing controller.
