Project:
Advanced:
Assigns a trigger to vehicle detection.<br/>The trigger is typically a Vehicle Passage Detector. It can also be an approach zone, either all sections or only the extremity. Even if no train detection is given, a condition can still apply.<br/>NR: strike-in or strike-out; the trigger is closely associated with vehicle detection<br/>

VehiclePassageDetector
Class   		Name:  
  		Name: isAssignedToVpDetector
 
Details:
The trigger is assigned to vehicle detection: a VP detector.<br/>
TdsSection
Class   		Name:  
  		Name: isAssignedToTdsSection
 
Details:
The trigger is assigned to train detection: a TDS section.<br/>
Signal
Class   		Name:  
  		Name: clearsSignal
 
Details:
The detection of a vehicle passage can clear a signal.<br/>For instance: in shunting areas, a treadle can clear the shunting signal.<br/>

Signal
Class   		Name:  
  		Name: closesSignal
 
Details:
Condition that forces the signal to close.<br/>This extra condition typically complements another condition that may close the signal earlier. <br/>The extra condition can be signal passed at danger (SPAD). In this case, more than one signal in the vicinity can be closed as a protective measure.<br/>de-DE: zweites Haltfallkriterium<br/>fr-FR: AXF Auxiliaire de Fermeture<br/>
Element Source Role Target Role
ArsRouteTrigger
Class   		Name:  
  		Name: usesTrigger
 
Details:
This train detection triggers the ARS call.<br/>
LevelCrossingActivation
Class   		Name:  
  		Name: usesTriggerAssignment
 
Details:
Link to a trigger assignment that informs about the activation of the Level Crossing <br/>
WarningSystem
Class   		Name:  
  		Name: usesTriggerAssignment
 
Details:
Informs about the equipment that triggers the warning system. <br/>
LevelCrossingRouteRelation
Class   		Name:  
  		Name: getsInputsFromTriggerAssignments
 
Details:
The process of activating a LX can depend on a series of inputs from trigger assignments. These inputs enter into a state machine. <br/>The state machine entry point is the LevelCrossingActivation.<br/>
RouteApproachLocking
Class   		Name:  
  		Name: usesTriggerAssignment
 
Details:
Link to a trigger assignment that informs about route locking.<br/>
Condition
Class   		Name: hasCondition
  		Name:  
 
Details:
 
LevelCrossingDeactivation
Class   		Name:  
  		Name: usesTriggerAssignment
 
Details:
Link to a trigger assignment that informs about the deactivation of the level crossing.<br/>
BlockElement
Class   		Name:  
  		Name: hasBlockClearanceTrigger
 
Details:
The equipment that reports passage of a train. This supports the clearance-proving of the block. Used for open lines without further technical equipment. <br/>de-DE: Schaltmittel zur Räumungsprüfung (E-Feld)<br/>
LineSideDetector
Class   		Name:  
  		Name: isActivatedByTriggerAssignment
 
Details:
The detector is activated by the detection of train passage (UK: strike-in).<br/>nl-NL: relatie met railcontact<br/>
