A method for adjusting urban rail train timetable groups

Abstract

The invention relates to a method for adjusting a timetable group of urban rail trains, which includes: identifying and tracking trains; calculating the train timetable; performing single adjustment to the current train timetable; calculating the minimum tracking interval of trains; and performing train delay single adjustment; Then carry out train delay group adjustment, including: recursively search the result of the offset of the current train and the time difference between the subsequent trains in the same direction and the same station is greater than the minimum tracking interval as the offset condition, if the offset condition is not met, start group adjustment, one by one for each The planned time of each train at each station is shifted, using a recursive method to determine the time difference between the affected planned shift and the subsequent trains at the same station in the same direction is less than the minimum tracking interval, using a recursive method to determine the deviation of the affected The time difference between the shifted result and the follow-up plan of m trains n in the same direction is greater than the minimum tracking interval. By adjusting each station, the stop time of each affected train and the interval operation level to fit the train after it arrives at the station and stops. The time is shorter than the planned arrival time. The impact on the plan is disgusted.

Description

technical field [0001] The invention relates to train management technology, in particular to a method for adjusting urban rail train timetable groups. Background technique [0002] The train operation diagram is the basis of the urban rail operation dispatching organization, and its task is to assign the occupied time of the station and the section and the accurate sequence of trains to each train in the system. If one of the trains is early or late, it may affect the operation of subsequent trains. At this time, it is necessary to adjust the operation diagram in real time. The adjustment of the operation diagram will not only affect the economic indicators such as operation efficiency and energy consumption, but also affect the train punctuality rate and passenger comfort. The scheme largely ensures the accuracy and high efficiency of train plan adjustment, while taking into account certain social benefits. [0003] With the development of urban rail transit, the automat...

Problems solved by technology

If in the multi-train plan, the running interval of the two trains 1 and 2 is relatively large, and the delay of train 1 is greater than a fixed value, the adjustment to the affected train 2 is an invalid adjustment; The running interval is small, and the delay of train 1 is less than a fixed value. At this time, the algorithm cannot effectively adjust the subsequent affected train 2

[0011] In scheme (1)(2), if the delay of the current train affects the operation of subsequent trains, the affected trains are not adjusted in advance, resulting in untimely adjustments.
