When train operations are disrupted due to accidents or incidents, passengers require relevant information in order to decide which train they should take. Research is being carried out on passenger decision making and their behavior when they obtain information regarding individual train situations containing prognostic, such as estimated arrival time or level of congestion on each train, in order to examine the efficacy of information provision for supporting decisions. This paper describes the results of an evaluation test aimed at grasping their train-choice behavior, in cases where train information was provided during travel delays.

Ideally, railway crew planning rosters should draw as little as possible on available crew resources. Methods of crew route scheduling with the evaluation criterion of the total number of required days have been studied because we could not figure the number of required crews out exactly at the time of setting it up. However this method for compiling crew route schedules has made roster scheduling more difficult. This paper therefore proposes a crew route scheduling method with the evaluation criterion of the estimated number of required crews and shows its effectivity for this problem.

When an operational disruption occurs, it is often the case that all trains on that line are suspended. This may significantly decrease services available to passengers, because even passengers who need not go through blocked sections are forced to wait until the cause of the suspension is removed. Deploying additional turn-back facilities and providing shuttle services can localize the negative effect of such disruptions. This research establishes a method for estimating the effectiveness of turn-back facilities from a passenger viewpoint. A series of case studies were compiled, which included experiments to evaluate the effectiveness of additional turn-back services.

The aim of this research was to improve the existing train operation and passenger flow simulator for detailed estimation of train movement on high frequency railway lines. For this purpose, a new method was introduced with calculates running time between stations depending on signal aspect, by simulating different signalling situations. A tool was added to calculate energy consumption for each estimated scenario. This paper explains the functions and features of the simulation system and offers an overview of the proposed method for calculating running time between stations. In addition, data was generated for a model high frequency line high, based on a hypothetical suburban commuter line to test to the calculation method.
