- There is strong motivation for having rail technology that is both international and interoperable. The practice, however, of moving technology that works well in one operational setting to another is not straightforward. This paper takes one type of technology, traffic control automation, and looks at variability between two contexts – GB and Sweden. The output from this work is a socio-technical framework which will be used to asses the viability of applying new advances in traffic management across a number of EU countries.

Reducing unnecessary cognitive load in train traffic control
- 2011
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Uppsala University has collaborated with Swedish National Railway Administration in research about train traffic control and how to improve traffic controllers’ work environment, so that they can better meet future demands. This has resulted in a new operational train traffic control system called STEG. The traffic controllers are today forced to develop and use very complex mental models which take a long time to learn. We have also found that their cognitive capacity is more used to indentify, understand and analyze the traffic situation and less to solve problems and find optimal solutions to disturbances. The objective for developing STEG was to change this situation and reduce unnecessary cognitive load. Interviews with traffic controllers show that STEG has reduced the complexity of their mental models and contributed to less unnecessary cognitive load in operation. Our conclusion is that by reducing the complexity of their mental model, they can be skilled much faster and they are now able to use their cognitive capacity and skills on the important parts of their work.

Analysis of collaboration applied to train drivers and train traffic controllers in Sweden

Konferensbidrag (refereegranskat)abstract
- Earlier studies of human operators in complex and dynamic work situations have demonstrated the importance of understanding the operator’s goal, mental model, observability, and controllability. Based on this model we have been able to analyse and design control systems and user interfaces supporting efficient control and high situation awareness. We now extended this model to include collaboration between different actors in complex control environments. This paper describes basic elements of the model, extension to collaboration, and its application to understand important problems and prerequisites for development of control systems in train traffic control in Sweden.

Designing train driver advisory systems for situation awareness
- 2013
-
Ingår i: Rail Human Factors. - London : Taylor & Francis. - 9781138000377 ; , s. 150-159
-
Konferensbidrag (refereegranskat)abstract
- During the past decade, train Driver Advisory Systems (DAS) have been an emerging topic. Many projects have been started with the goal to increase punctuality and decrease energy consumption. We found that many systems provide too little information, e.g. only a speed advice, and thus do neither improve drivers’ skills nor their Situation Awareness (SA) of the traffic situation. In collaboration with train drivers, we developed key concepts for future DAS. This paper discusses today’s problems and principles to solve them. We explain how SA can be supported and how this can improve overall quality of train traffic.
