Abstract
Nowadays, railways are confronted with numerous pressing problems, including
capacity optimization, energy conservation, cost reduction and improving
customer satisfaction. While the traditional railway is a very safe means of transportation,
it still cannot meet all these requirements. Hence there are high interests
in two available systems to overcome these challenges: Traffic Management
System (TMS) and the optimized Automatic Train Operation (ATO). TMS is an
efficient solution, which centralizes data to the railway infrastructure manager,
while optimized ATO is an on-board approach available to minimize the loss of
efficiency caused by manual operation. Until now, there are a lot of research
studies about TMS and ATO as separate subjects. However, there is only poor
research, which aims at closely coordinating the optimization strategies of TMS
and ATO. This is because TMS is limited in the network scheduling
optimization, while optimized ATO is centred on train behaviour optimization.
Therefore this article presents the key idea of this research is to bridge the gap
between TMS and ATO, to make progress towards combining the knowledge
from both the infrastructure side and the train side. The primary objective is to
bring an added value for achieving higher capacity, less energy consumption and
higher operation quality by integration of Automatic Train Operation with
centralized Train Management. In addition, an optimized ATO approach is
introduced by integration of predictive fuzzy control with analytical hierarchy
process. If this research has a positive response, it could bring about a new
