ISE C18- Fail-Safe Train Positioning

Researchers: Mats Bengtsson (Project manager), Wendi Löffler (PhD student)

Source of Funding: Trafikverket (Swedish Transport Administration)/ S2R

The project contributes to the work on train positioning within Shift2Rail, where Trafikverket is the Swedish
partner in Shift2Rail using KTH based researchers as linked third parties. The goal is to replace physical balises by a combination of odometry, satellite based navigation (GNSS) and other sources, such as inertial measurement units, as well as maps. The train position is obtained by fusing information from different sources and exploiting the known map. Obviously, safety to failures and measurement outliers is a crucial feature. In particular, we are analysing how sensitive the estimated position is to errors in the maps, since obtaining and maintaining accurate maps is costly.
