Railway transportation of passengers and goods is an essential gear to keep the engine
of our urbanized society running. Safety and reliability are core aspects and can only
be enabled by meticulous infrastructure maintenance. Currently, this is not given in
all aspects as track infrastructure monitoring is mainly conducted by combining two
methods: 1) partially a frequent superficial monitoring by employees, and 2) an
occasional, precise monitoring using cost-intensive measuring vehicles. Increasing the
precision and frequency of infrastructure monitoring is not reasonable (time and
money) with the current methods. This issue has also been raised by FFG in the call
VIF 2017. Our company has been awarded funding and has successfully completed a
detailed analysis and solution proposal in cooperation with the Austrian Federal
Railways (ÖBB) in the study KOMBI (Kontinuierliches Onboard Monitoring der Bahn-
Infrastruktur).
The HARMONY project aims to develop an intelligent on-board monitoring system
mountable on regular trains to support the operator’s staff in decision making in
relation to immediately necessary maintenance work and eventually consequential
operational constraints. The design of this system draws upon the results of KOMBI
allowing a high-frequency and low-cost monitoring. The project outlined in this
proposal comprises of two key aspects: 1) The intelligent processing of the data
collected by the on-board system equipped with the sensors as determined in KOMBI,
and 2) gaining an in-depth understanding of human factors to increase the overall
railway system safety and analyse user acceptance for a diverse audience and the
definition of a new role in the (railway) work force: The Remote Analyst.
The first aspect aims to find answers on how to efficiently reduce and transform huge
amounts of sensor data into relevant information on potentially safety-critical
infrastructure issues in real-time and on-board a regular train prior to transmission to
a remote human operator. Solutions are needed for the selection of suitable data
analysis tools, sensor correlation methods, data interpretation and synchronisation
methods by considering economic constraints and high demands on robustness,
performance and dependability. Furthermore, the system requires a suitable design
in relation to necessary processing methods and units on-board.
The second aspect of this project aims to focus on human-machine interaction and
Human Factors Safety, investigating implications of our system on the human
workforce and its benefits to the overall railway system safety, including human
interactions. By conducting information stream design, a human performance process
and a business process analysis within an interdisciplinary team, we will define and
design a holistic solution that creates an inclusive work space for people of different
backgrounds, genders and age groups in the railway industry.
The research results from this project will provide solid groundwork upon which a
more frequent and cost-efficient condition-based railway maintenance as well as a
safer and more reliable railway operation system can be built. This system will
alleviate decision making for human operators, provides a tangible solution for
increased user acceptance and opens up novel possibilities for remote
operations/control of autonomous machines/vehicles.
