[0002] Urban rail transit is affected by factors such as bad weather and large-scale events, which can lead to a sharp increase in passenger flow in a short period of time. If the large passenger flow is not evacuated in time, it will lead to a backlog of passengers in the station, prolonged passenger detention time, excessive train load factors, and even safety hazards such as passenger crowding and trampling, which will greatly reduce passenger travel satisfaction and operating efficiency.

[0003] The heavy passenger flow refers to the situation where the current mainline capacity is unable to evacuate the passenger flow, that is, the sum of the remaining capacity of trains arriving at the heavy passenger flow platform is greater than the platform passenger flow, which is considered a heavy passenger flow event.

Due to the lack of corresponding basic theoretical support and scientific methods for adjusting the driving organization plan, it will lead to untimely evacuation of passenger flows, unreasonable scheduling, potential safety hazards, low passenger travel satisfaction and low operating efficiency. Therefore, it is necessary to study the issue of spare vehicle scheduling. Summary of the invention

[0035] The beneficial effects of the present invention are as follows:

[0036] In the prior art, the means of adding spare vehicles to evacuate large passenger flows usually relies on manual experience. Due to the lack of corresponding basic theoretical support and scientific methods for adjusting driving organization plans, there are unreasonable scheduling situations during manual scheduling, which poses a safety hazard and reduces passenger travel satisfaction and operating efficiency.

[0037] In this application, adjustments are made in two dimensions. The first dimension adjustment keeps the number of adjusted vehicles unchanged, and increases the allowed adjustment time by gradually increasing the adjustment platform. If the adjustment to the starting station still does not meet the conditions for adding spare vehicles, the second dimension adjustment is performed. The second dimension adjustment uses vehicles as step units to increase the range of adjusted vehicles. The first and second dimensions are performed alternately to gradually expand the adjustment range of vehicles, providing theoretical and methodological support for operating companies to reasonably add spare vehicles, so as to reasonably, timely and efficiently evacuate large passenger flows and improve passenger travel satisfaction and operating efficiency.

[0040] The present invention is further described below.

[0041] Large passenger flow means that the current mainline capacity cannot evacuate the passenger flow, that is, the sum of the remaining capacity of trains arriving at the platform with large passenger flow is greater than the platform passenger flow. The passenger flow information can be analyzed and predicted, and the current capacity can be judged based on the driving information, passenger flow information, train load rate and other information to determine whether the large passenger flow can be evacuated.

[0048]

[0049]

[0050] In the train and train This is explained by taking the example of adding a spare car.

[0051] The conditions for opening the spare vehicle are as follows:

[0052] Condition 1: Train ,train The interval between departures ;

[0053] Condition 2: The departure interval between trains ≥ .

[0054] Only when both conditions 1 and 2 are met, the conditions for adding a spare vehicle are met. If any one of the conditions is not met, the conditions for adding a spare vehicle are not met.

[0055] S2. Calculation train ,train exist The departure interval of the platform .

[0058] like , execute step S3, wherein, Indicates the minimum departure time interval on the line;

[0059] like , execute step S4;

[0060] S3. On the train ,train Add a spare car in between.

[0062] If the train ,train The operation plan has been adjusted and the departure time of the spare vehicle train Arrived after adjustment Platform time .

[0063] S4, perform the first dimension adjustment to determine whether the conditions for adding a spare vehicle are met: if so, add a spare vehicle; if not, execute step S5;

[0064] The first dimension adjustment flow chart is as follows Figure 2As shown, the first dimension adjustment refers to increasing the allowable adjustment time by adding adjustment stations, that is, from The previous platform of the platform starts adjusting ( The previous platform of the platform is denoted as Platform), and determine whether the conditions for adding a spare car are met after adjustment. If so, add a spare car; if not, continue to adjust with the platform as the step unit, and each adjustment range increases by one platform until the conditions for adding a spare car are met, or adjust to the starting station; specifically, the following steps are included:

[0065] S401, Calculation Train ,train Target adjustment time

[0068] in, is the minimum departure time interval of the line; To adjust the front train ,train exist The departure interval of the platform.

[0069] S402: Calculate the total allowable adjustment time of trains between platforms .

[0070] The sum of the allowed forward adjustment time and the allowed backward adjustment time is as follows:

[0071] Allowing forward time adjustment means adding trains ,train The time interval between departures will be The time the station time is adjusted forward. Allows the time to be adjusted forward for For example, when the first round of first-dimension adjustment is performed (without second-dimension adjustment), the train adjustment object for which the forward adjustment time is increased is the train ; When performing the second round of first dimension adjustment (after performing the second dimension adjustment once), the train adjustment object corresponding to the allowed forward adjustment time is increased to and , and so on. The allowed forward adjustment time is the sum of the allowed stop forward adjustment time and the allowed running forward adjustment time. The allowed stop forward adjustment time is obtained by shortening the stop time, and the allowed running forward adjustment time is obtained by increasing the running speed and thus shortening the running time; the allowed stop forward adjustment time refers to the sum of the difference between the default stop time and the minimum stop time of all train adjustment objects at the adjusted platform. The adjusted platform refers to the platform where the stay time needs to be adjusted during the first dimension adjustment. For example, the first adjustment platform in the first dimension is Platform; the second adjustment of the first dimension is Platform and The platform before the platform ( The previous platform of the platform is denoted as Platform); the third adjustment of the first dimension to platform Platform, Platform and The platform before the platform, The previous platform of the platform is denoted as The allowed forward adjustment time refers to the time when all train adjustment objects travel from the first adjustment platform to The sum of the differences between the default running time and the minimum running time of the station. For example, when the first dimension is adjusted for the first time, it means from Platform to Platform, the second adjustment of the first dimension refers to Platform to Platform, the third adjustment of the first dimension refers to Platform to Platform, and so on.

[0072] Allowing the time to be adjusted backwards is to increase the number of trains ,train The time interval between departures will be The time that the station time is adjusted backward. Allows the time to be adjusted backward for For example, when the first round of first-dimension adjustment is performed (without the second-dimension adjustment), the train adjustment object for which the backward adjustment time is allowed is the train ; When performing the second round of first dimension adjustment (after performing the second dimension adjustment once), the train adjustment object for which the backward adjustment time is allowed is increased to and , and so on. The allowed backward adjustment time is the sum of the allowed stop backward adjustment time and the allowed running backward adjustment time. The allowed stop backward adjustment time is obtained by extending the stop time, and the allowed running backward adjustment time is obtained by slowing down the running speed and then extending the running time. The allowed stop backward adjustment time refers to the sum of the difference between the maximum stop time and the default stop time of all train adjustment objects at the adjusted platform. The adjusted platform refers to the platform where the stay time needs to be adjusted during the first dimension adjustment. For example, the first adjustment platform in the first dimension is Platform; the second adjustment of the first dimension is Platform and The platform before the platform ( The previous platform of the platform is denoted as Platform); the third adjustment of the first dimension to platform Platform, Platform and The platform before the platform, The previous platform of the platform is denoted as The allowed backward adjustment time refers to the time from the first adjustment platform to the end of the adjustment period of all train adjustment objects. The sum of the differences between the maximum running time of the station and the default running time. For example, when the first dimension is adjusted for the first time, it means from Platform to Platform, the second adjustment of the first dimension refers to Platform to Platform, the third adjustment of the first dimension refers to Platform to Platform, and so on.

[0090] Calculate the adjusted train arrive Platform time:

[0091] Because the train After the platform stop time is shortened to the minimum stop time and the running time between platforms is reduced to the minimum running time, the adjusted train arrive The station time is .

[0092] Calculate the adjusted train arrive Platform time:
