Abstract
In recent years, railway faces enormous growth but without enough increase in capacity, making railway networks more and more saturated. The demand for capacity improvement has probably never been greater than today on the limited infrastructure. There are two real-time optimization methods to tackle the railway capacity challenge: real-time rescheduling and automatic train operation. Real-time rescheduling increases efficiency of infrastructure management, while automatic train operation is an on-board approach available to minimize the loss of efficiency caused by manual operation. While both methods have proved successful separately, it seems that each lacks some of the benefits of the other. This is because real-time rescheduling assumes trains to behave exactly as instructed and its performance depends on the accuracy of traffic plan execution, while automatic train operation is centred on train level optimization resulting lack of knowledge about other trains in the railway network. Therefore, this research aims at closely coordinating the optimization strategies of real-time rescheduling and automatic train operation, making capacity improvement towards combining the knowledge from both the infrastructure side and the train side. A potential increase of capacity by this integration idea is analysed based on an enhanced “balance of capacity” model. If this integration strategy has a positive response in operating capacity, it might also indicate less restriction for the timetabling capacity design. Show more
