Analysing railroad congestion in a dense urban network through the use of road traffic network fundamental diagram concept
Transilien, the branch of SNCF in charge of operating the main urban railroad network in the area of Paris, faces a regular increase of passenger flows. The planning of railway operations is made carefully: simulation runs permit to assess the timetable stability. However, many disturbances appear and cause trains delays. Due to the nature of the railroad network those delays are cumulative and an on-line update of the timetable is not always successful in maintaining the train’s schedule. In this tensed context, operators are searching solutions to better use the infrastructure capacity. A needed step towards this objective is a better understanding of the phenomena of disruptions. This paper explores the possibility to transpose a traffic flow theory tool, the network fundamental diagram, in the field of dense railroad traffic. We show how to build a network fundamental diagram for a railroad system and how to interpret some obtained shapes for those diagrams.
