Conflict detection
Each train is searching conflict:

Each conflict = several solutions (2 – 4) Each solution = new daughter scenario several daughter scenarios, in each:

ARS According to Train Path
Interlocking states are mirrored in Base simulation „What is possible in GTN should be possible in
interlocking“
=> Low probability of request rejection by interlocking
Other Automatic Functions
Route cancelation Time synchronization Anticipated / real
departure insertion Train number
insertion, editing Individual point control Line consent request Locking the closed
level crossing
Tasks to Solve
Collision access to some platforms Input information
Temporary speed restrictions• different infrastructure models
– IS IM X GTN Výhled
Exceeded loading rate Waiting times, rolling stock circulations
Interface to Operating Personal
ARS control through JOP X GTN
Possible commands: Editing station / line track Editing dwell / departure time Turning ARS on / off
• train• station• controlled area
Absolute / disposition stop
ARS Behavior
High traffic intelligence => most of routes set without dispatcher intervention
Warning if route cannot be set Dynamic adaptation to dispatchers
commands on JOP ARS with advance
enough time for route cancelation by dispatcher
