Punctuality analysis by the microscopic simulation and visualization of web-based train information system data

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. The authors introduce an approach to foresee and analyse punctuality for railway lines where trains are densely operated. The authors 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, the authors visualize train traffic record data using the Chromatic diagram. In the forecast phase, the authors use a microscopic simulator that the authors have developed. In this paper, the authors show their experience of applying this approach when a part of a track was relocated in the Odakyu electric railway company.
