Subway operation is a complex system, which is influenced by people, machines and environment, making all kinds of situations in operation random and complex. Such as train delay, passenger flow increase or decrease, operation disorder, unexpected events, equipment failure, etc. The organizers are required to take timely and reasonable traffic adjustment measures according to the changes of the situation in the operation organization work, so that the trains can run safely and punctually according to the train execution diagram as much as possible. In practical work, in most cases, when adjusting traffic, the adjustment method is not single, but parallel in many ways according to the actual situation, which will increase the attention and operability of traffic dispatchers and produce more unsafe factors. Therefore, in the process of train adjustment, it is necessary to maximize the potential of subway personnel, equipment and facilities, maintain degraded operation services, control the work focus and workload of train dispatchers within a certain range, and pay equal attention to safety and efficiency.

The role of schedule adjustment in 1 subway traffic organization

With the rapid development of subway construction in major cities, the research on the adjustment mode of subway traffic organization and scheduling has also been paid attention to. The operation of the subway is a complicated process, full of changes and complicated procedures, and there will be more uncertainties. Subway operation is affected by many factors, such as passenger flow, time delay, emergencies and equipment problems. When dealing with these changing factors, it is necessary to adjust the train schedule in time to solve the problem, so that the subway train can be executed according to the train execution diagram.

The adjustment of train schedule in the face of emergencies and emergencies has the greatest influence, which is related to the safe operation of the whole train organization. Therefore, scientific adjustment should be made under the principle of safety, and subway facilities and equipment should be used to ensure a certain operating state of the subway and reduce the adverse effects of emergencies and emergencies on the subway.

2 subway traffic organization and scheduling adjustment principles

The dispatching adjustment in the subway traffic organization should adhere to certain principles, so as to truly maintain the operation capacity of the subway and reduce the influence of unfavorable factors. The author hereby puts forward the following principles:

2. 1 security. Safe operation is the first guarantee for subway and other modes of transportation. Safety is the most basic respect for people's life and health and property safety, and it is also the need to ensure the safety of driving and equipment. Therefore, schedule adjustment must be carried out on a safe basis.

2.2 Timely. Schedule adjustment is mainly made to deal with emergencies and unexpected events, so it must be timely in response, adjustment and effect, which requires that schedule adjustment can respond sensitively to the situation before or at the beginning of the event and control it in time and effectively.

2.3 the whole. Dispatching adjustment in traffic organization should focus on the overall interests and deal with emergencies or emergencies. The measures taken are not aimed at single equipment failure or single event itself, but comprehensive consideration of other factors to make decisions.

2.4 Information notification. The subway operation faces the public and provides services for the public. The corresponding schedule adjustment should also consider the impact on passengers, and the information related to passengers should be disclosed to passengers in time to minimize the impact on passengers.

3 subway traffic organization schedule adjustment model analysis

The work of subway traffic organization is highly concentrated, which requires close cooperation and timely response to various emergencies. Therefore, it is necessary to adopt different traffic organization methods and different dispatching adjustment methods according to different specific conditions. Dispatching in subway traffic organization refers to the work of commanding according to the train diagram. When the unfavorable factors fail to follow the train execution diagram, it is necessary to adjust the timetable under the principle of safe, timely and overall good information notification, so as to ensure the punctual operation of the train on the basis of safety. The following are the main modes of dispatching adjustment in subway traffic organization:

3. 1 train shutdown and logoff. If the subway train has serious faults, it should stop running in time. If it can't be repaired in time, it should be offline and temporarily out of service. The dispatching adjustment method of stopping or getting off the bus should be carried out at the starting station or terminal of the subway. If the train breaks down at the intermediate station, it can also be stored or returned to the factory for maintenance.

3.2 Add and replace trains. In the former case, it is necessary to organize spare trains to increase the number of trains to replace the failed off-line trains. In the case of increased passenger flow, the method of increasing the number of trains can also be applied. If the train gets off the line or stops at the terminal, it can be replaced by a standby train and run according to the original line and plan. The main purpose of adding and replacing trains is to ensure a balanced number of trains providing services online and provide adequate services.

3.3 Seizure and temporary parking. Arrest refers to the way to detain the train to be executed at the station; Temporary parking refers to the way that trains are temporarily parked on the line in the interval. The dispatching adjustment methods of car impounding and temporary parking are mainly used when train lines or stations fail. For the impounded vehicle, it is necessary to arrange the release organ, which is generally arranged by the impounding subject; For trains that stop temporarily, the train staff * * * mainly means that the driver * * * tries to tell the passengers the reason and do a good job of appeasement. In subway operation, impounding and temporary parking are also the main dispatching adjustment methods in the face of emergencies, which is an inevitable guarantee for providing time for online faulty vehicles to deal with them well.

3.4 Slow down and extend the parking time. Some trains have a short fault handling time, so there is no need to stay or stop temporarily. We can make more time for the faulty train to deal with the fault by slowing down other trains or extending the stop time. At the same time, we should also deal with the running time interval and give consideration to coordination and safety.

3.5 Speed-up driving and non-stop dispatching adjustment methods. When the train is late, the arrival time will be delayed. To this end, we can speed up the train or organize the train to pass the station directly, which has a great impact on passengers. Train drivers should explain and appease the passengers on board, and station staff should do a good job of informing and serving the waiting passengers. Therefore, in order to take care of passengers' needs, non-stop scheduling adjustment is generally not adopted in stations, departure stations and docks with large passenger flow. It is also necessary to arrange and coordinate non-stop stations to avoid a train passing through multiple stations in succession or multiple trains not stopping at a certain station, which will bring more inconvenience to passengers. The on-line execution train can go straight without stopping when the passenger flow is large.

3.6 rescue. If the train running on the line breaks down, it will slow down or stop, which will cause congestion for a long time. If not handled in time, it will affect the normal operation of the whole line. Therefore, in this case, it is necessary to arrange the rescue of the front train or the rear train, arrange the evacuation of passengers, and send the faulty train to the storage line or return to the factory for maintenance in time. Some vehicle execution problems are caused by the failure of power supply system, and it is necessary to arrange internal combustion engineering trains for rescue.

In addition to the above-mentioned dispatching adjustment methods, there are other dispatching adjustment methods in subway traffic organization, such as reverse execution of trains, two-way execution of single track, early or delayed departure of departure stations, changing trains, etc., all of which are suitable for different specific situations in normal operation. The dispatching adjustment of traffic organizations should be divided into authority and responsibility to avoid multi-head command and unmanned management. Through the application of Nanjing Metro 1 Line, the above-mentioned traffic organization scheduling adjustment method has solved the problems and faults in time and played a significant role.

4 conclusion

The application of train adjustment is not a simple mechanical copy, but the best or better adjustment method is selected according to the specific situation, with little impact on the whole line operation and passenger service, easy implementation, safety and reliability as the measurement standard. When the subway has a great influence on faults and incidents, a variety of train adjustment methods will be applied. In this case, train adjustment needs to pay more attention to more safety key points, issue multiple dispatching commands and perform multiple signal operations, which requires train adjustment to be carried out. Especially when the adjustment methods such as reverse execution, small cross execution, one-way and two-way execution and train rescue are used, train dispatching can quickly quantify the train interval, train cycle and number of trains on the whole line or a small cross, which not only tests the post skills and practical experience of train dispatchers, but also puts forward the comprehensive application skills of train adjustment methods.
