Abstract: In case of natural or human-made hazards, it may become necessary to evacuate a large number of people in a short time. Especially metropolitan railway stations are important junctions for rail traffic and can play an important role in large-scale evacuations. To handle a large volume of people in and around the station special measures are needed. The project KapaKrit investigates the impact of rail-based evacuation approaches. In particular, the estimation of the capacity in case of large-scale emergency evacuations is investigated. The goal of the project is to create an open-access tool to evaluate the capacity of a station. This tool will include the simulation software but also methods to estimate the needed model parameters. The presented poster aims to introduce the currently running project by showing three selected research highlights. We envision discussing the current state and get expert feedback for the remaining project activities.The first highlight is the modelling of pedestrian movement in the building, including the train entering process. Special structural, technical and organisational measures are investigated to maximise the capacity of the train station. Therefore, the Jülich Pedestrian Simulator (JuPedSim), a software tool for pedestrian movements is used. A 3D model of a station is set up, containing the station building, the individual platforms as well as different train types. Simulation studies of the movement of passengers, with variations of entrance inflows, operational options as well as train schedules, were conducted. This allows deducing the capacity of the whole system, i.e. station building, platform management and rail traffic.The other two highlights cover the results of the conducted field studies. The first one investigates the train entrance process by capturing the time passengers need to enter a train. This is done during low and high occupancy rates, e.g. during events and commuter phases. The second one measures the pedestrian flow in the station building and the platform connecting the tunnel. Both studies provide boundary conditions, e.g. train entrance times and inflow rates, for the numerical simulations.
