- 0 Free    Zone that was occupied before, which has now been left
- 1 Train   Zone where the train actually is.
- 2 SafetyB Safety zone behind the train. extends 4m
- 3 SafetyF Safety zone in front of the train. extends 4m
-			If a train is about to enter this zone, immediately brake it down to 2
- 4 CpB     Backside coupling zone. If the coupling zones of 2 trains overlap, they can be coupled
- 5 CpF     Frontside coupling zone
- 6 Brake   Brake distance of the train. Extends to the point ~5 nodes in front
-			of the point where the train would stop if it would regularily brake now.
- 7 Aware   Awareness zone. Extends 10-20 nodes beyond the Brake zone
-			Whenever any of the non-aware zones of other trains are detected here, the train will start to brake.

 It turned out that, especially for the TSS, some more, even overlapping zones are required.
 Packing those into a data structure would just become a huge mess!
 Instead, this occupation system will store the path indices of positions in the corresponding.
