摘要

Rail traffic simulation tools are used for timetable design and for the analysis of existing timetables. For these models, correct data for infrastructure and rolling stock are needed. Parameters are often estimated, but this can lead to differences with real train operation, especially when these models are used for timetable designs of lines or networks with larger distances. Important in this respect is the validation of the running times, speed profiles and track occupation times. In this paper, the validation of a simulation model is described. The running times in this model are based on the calculation of traction force and resistance of Dutch trains. Acceleration and braking rates are determined from measured data. Validation takes place on the basis of train detection data of an Intercity and an Interregional train on the line from Rotterdam to The Hague HS (The Netherlands). In the case of the Intercity, standard trains are operated. The result is a running time, calculated by the simulation model RailSys, which is 5.7 % larger than the minimum running time measured by train detection data. This small difference is rather acceptable. The validation of the Interregional train shows a large difference between the model calculation and the train detection data: 11.9%. There were serious problems with the disposition of trains. Due to lack of data of actual train disposition, it was impossible to either select the appropriate trains or to calculate the appropriate running times.
