Monitoring of speed incursions in DB long-distance traffic
In an interactive web application, GPS data and other data are used to display sections of long-distance traffic (FV) on which trains are travelling more slowly than usual.
Slow speed points recognisable at a glance
Focusing on the most important jobs possibleÂ
Challenge
- In slow speed sections, FV trains may only run at reduced speed.
These therefore have a significant influence on the FV punctuality of Deutsche Bahn - Slow speed sections of high speed traffic (>160km/h) are not relevant to safety and therefore do not need to be recorded centrally
- Due to this difficult data situation, there is a lack of transparency about the current operating situation and efficient management of punctuality is difficult.
Solution
- Speed dips are determined from the GPS data of long-distance trains using an empirical approach
- The identified route sections are visualised on a map and their relevance is determined based on the travel time loss from the operational data
- An R-Shiny web application intersects the data with information from the network control centre and provides the content to a panel of experts
Result
- The slow speed sections are compiled in a view
- A focus on the most important places is possible on the basis of the travel time loss
