  4. GTN Výhled Mathematical Model of Anticipated Traffic Computation of conflict-free Anticipated traffic Base Simulation • Immediate train running • Infrastructure states • Automatic train route setting 4

  5. Computation of Anticipated Traffic in GTN Výhled Choosing the tracks Static -> dynamic speed profile Occupation times Conflict detection and solution Displaying of Anticipated traffic Automatic Train Route Setting

  6. * * * Marking Algorithm * * * Static speed profile Dynamic speed profile

  7. Running Times V s Time of beginning / end of physical occupation of track section

  8. Occupation Times Time for clearing Time for route release Occupation time Journey time of occupied block interval Time for approach section Train length Time for route formation t

  9. Conflict detection s Second train Work direction of detection algorithm of second train First train Station First detected overlap of occupation times Each train is searching conflict: t

  10. Each conflict = several solutions (2 – 4) Each solution = new daughter scenario several daughter scenarios, in each: conflict detection and solution several new scenarios, in each . . . Tree of scenarios Solution of Conflicts

  11. 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

  12. Other AutomaticFunctions • Route cancelation • Time synchronization • Anticipated / real departure insertion • Train number • insertion, editing • Individual point control • Line consent request • Locking the closedlevel crossing

  13. Tasks to Solve Collisionaccess to some platforms Input information Temporary speed restrictions different infrastructure models IS IM X GTN Výhled Exceeded loading rate Waiting times, rolling stock circulations

  14. Interface to Operating Personal ARS controlthrough JOP X GTN Possiblecommands: Editing station / line track Editing dwell / departure time Turning ARS on / off train station controlled area Absolute / disposition stop

  15. 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
