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

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

** * * ** Marking Algorithm Static speed profile Dynamic speed profile

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

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

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

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

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
