DEDOTS Session Summary


The second half the DEDOTS session (10:00-12:00 of Thursday 25th August) discussed issues around the following four themes associated with the development of future traffic management systems: 1) Application and Integration; 2) Evaluation; 3) Simulation; 4) Traffic Optimisation and Management. Participants were divided into groups and had a brain storming session for the themes. The discussions were recorded in a form of post-its/flipchart. The outputs can be seen towards the end of this report.

Some of the issues highlighted were

  • Complex nature of the rail industry (different players: Operator, Infrastructure Manager, etc). There are initiatives for collaborative working, but because of the complexity, the speed of innovation does not match what is happening outside the railway. Recommended is a sand-pit approach, in which a small group consisting of a small number of people from various parts of the industry, work together, and show preliminary examples.
  • Access to the data is an issue. Different players (e.g. infrastructure manager, operator) have different datasets. In some cases, data is available but it takes much effort to make it usable (because of missing data/discrepancy within the data). A scope for a collaboration platform for data mining/cleaning/sharing (common test-bed). This would also allow SMEs that do not necessary have data collection capabilities, to work in the railway traffic management domain.
  • Needs for common and open simulation models. Such models can be used for not only traffic modelling but also energy saving evaluation, etc.
  • Passenger-oriented evaluation would be key in evaluation.
  • Different optimisation/simulation models have been calibrated/validated in different ways, and it is difficult to compare them. A scope for IEEE standard for validation of traffic models. Such a standard should take account of, for example, ETCS developments, in order to accelerate integration of traffic management models into ETCS development.
