En granskning av information över tågförseningar år 2012


The purpose of this report is to document the quality of data from the Swedish Transport Administration regarding train delays, in order to assess whether it can be used to deepen the understanding of the size of the delays and the conditions that generate delays. In order to limit the work we have only considered quarter 1 of year 2012. The overall impression is that the quality of the data has become much better. It is not obvious whether this is due to better reporting/insertion of data or if new methods to extract data from existing systems have been developed. It is also important to emphasize that with the increased knowledge of the data the possibilities to deal with some ambiguities that we earlier saw as inaccuracies in the material have increased. Our hope is that with data from year 2013 and onwards it should be possible to perform structured analyses of delays in the whole rail network in Sweden. As a first step towards analysing patterns of delays in the rail traffic we have presented a description of the delay pattern on the so called “Dalabanan”, i.e. the traffic between Mora/Falun/Borlänge and Stockholm, and also at “Uppsala-pendeln” between Uppsala and Stockholm.

A greater understanding of cyclists' behaviour
