Abstract
With the rapid increase of passenger volume, the interval of some rail transit
lines in China has reached a minimum value, which makes turn-back capacity
one of the main capacity-limiting factors instead of section headway, particularly
during the peak hours on workdays. A general simulation modeling framework
and algorithm in which the divide and conquer rule is adopted for train
scheduling problems on a multi-interval rail transit line with turn-back track
constraint is proposed in the paper, and the objective is to obtain a feasible
timetable based on passenger demand at different time periods, line capacity,
number of rolling stocks, location of depots, train routing, turn-back type. Lastly,
a new version of the TPM software is programmed by the proposed framework
and algorithm, and Shanghai Rail Transit Line 2 is presented to demonstrate. The
result shows that the proposed algorithm performs very efficiently, and a feasible
timetable with a five-interval period, 535 trains and one turn-back track
constraint at GLR station is generated in 15 seconds by TPM.
Keywords: rail transit, train scheduling, multi-interval, turn-back track
