Abstract
In order to increase the robustness of a railway system, the detailed analysis for a
combination of tracks, signalling systems, timetables and operation of trains is
indispensable. We introduce an approach to foresee and analyse punctuality for
railway lines where trains are densely operated. Our approach consists of three
phases, namely, the analysis of the current situation of train operation
(observation phase), the forecasting of the future situation of train
operation (forecast phase) and the analysis of train operation after some changes
are made (checking phase). In the observation phase and in the checking phase,
we visualize train traffic record data using the Chromatic diagram. In the forecast
phase, we use a microscopic simulator that we have developed. In this paper, we
show our experience of applying this approach when a part of a track was
relocated in the Odakyu electric railway company.
Keywords: robustness, punctuality analysis, microscopic simulation, track
circuit, visualization.
