Data Quality Management
The Train Information System (TIS) is a traffic data collection tool managed by RNE. It can be used to analyse train performance, both at company level (for example, RUs that receive raw data from RNE to feed into their own company systems) and at international level (Rail Freight Corridors).
TIS data quality is a crucial factor in ensuring the reliability of analyses and the applicability of the conclusions drawn.
However, ‘TIS data quality’ may have different meanings. Therefore, RNE has created a structured framework defining the different meanings of data quality and their related procedures (reports, evaluation, corrective actions, responsible partners, KPIs) and published them in the ‘Handbook for TIS Data Quality Management’.
In order to provide reliable information, data quality checks have to be performed. A process has been implemented, in which the respective partners responsible at the different stages are involved (IT provider, RNE and Infrastructure Managers (IMs)). In addition, a network of the IMs respective Data Quality Contact Persons (DQCs) has been established.
