Dynamic model of a railway system Beginning

• Doctoral studies at TU Braunschweig
• Methods to acquire and manage data in railway
• Analyse problems with human-machine-interface (HMI)
• Investigate human factors with simulations
• Simulation base with localisation and time information

Dynamic model of a railway system Laboratory

• Build up to test the hypothesis from the research
• Simulators and components
• Adoption of the one and only SBB full motion simulator Re 460
• Adoption and refactoring of the simulator Re 420 (LOCSIM)
• Refactoring und implementation of a signal box (Obermatt-Langnau)

Dynamic model of a railway system Objective I

• Investigate complex problems
• Point out the necessity of simulation models
• Analytical modelling with focus on HMI to apply research hypothesis

Dynamic model of a railway system Modelling procedure

Collect

• Video based capturing of railway tracks and environment
• Capture meta data (GPS)

Preparation

• Extend video data with meta data by the use of QRailScan

(GPS, Infrastructure)

• Approach to maximize compatibility with standard data format (XML)

Dynamic model of a railway system Modelling procedure

Environment Infrastructure

• ZUSI System (virtual environment)
• LOCSIM (video)

Interlocking

• Digitalize interlocking table (standard format - railML?, rule Engine)
• Elaborate interlocking logic (interlocking table + specific interlocking

know-how)

Dynamic model of a railway system Modelling procedure

Verification

• Verify the model and check coverage with the
• bjectives
• Analyse with investigated methods

Apply

• Test the hypothesis of the research
• Real occurrences for test scenarios

Dynamic model of a railway system Objective II

• Approaching to a standard data base structure for data management,

flexible data storage and data transfer

• Standard methods to integrate simulation components

(driving simulators, signal boxes, operation control)

• Possibility to optimize conditions in simulation environment for staff

training and qualification

• Investigation and research to develop methods for automatic data

acquiring (ETH Zurich)

Implementation

• Standard data format
• Stable standardized interface
• Communication between different

systems

• Individual configuration of

simulation components

• Data stream over TCP/IP interface
• Modularized

DESM Middleware railML

• Are there standard infrastructure attributes with localisation and

characteristics over time? (version control)

• possibility to model interlocking logic? (rule engine)
