Advanced:
A level crossing (LX) is activated, i.e. requested to close for road traffic, upon train approach. This happens when the train crosses a detection point, i.e. an insulated track joint, axle counter or treadle. These approach detectors are commonly referred to as Approach Starting (AS).<br/>
Attribute
Public EntityILref
  hasInterface
Details:
position=1
Notes: Reference to physical description of level crossing interface with list of commands to the field and notifications from the field<br/>
Public EntityILref
  isLevelCrossingType
Details:
position=2
Notes: Reference to the basic type of level crossing. It refers to a basic configuration of a level crossing for this IM.<br/>
Public EntityILref
  refersTo
Details:
position=3
Notes: The reference to the physical level crossing in infrastructure.<br/>
Public BarrierDeactivator
  deactivatedBy
Details:
position=4
Notes: The description of deactivation conditions for this level crossing.<br/>
Public ActivationCondition
  activationCondition
Details:
position=5
Notes: Description of the possible activation conditions of this level crossing.<br/>
Public EntityILref
  hasTvdSection
Details:
position=6
Notes: The reference to the TVD section(s) directly at the level crossing<br/>
Public EntityILref
  hasLevelCrossingTrack
Details:
position=7
Notes: Reference to the track elements (TrackIL) which are used to indicate the level crossing status related to this track.<br/>
Public tLevelCrossingState
  preferredPosition
Details:
use=optional
Notes: This is the state of level crossing under normal conditions, i.e. when not in use. For most level crossings this would be the open state.<br/>
Public duration
  typicalTimeToClose
Details:
use=required
Notes: Average time between the time a train detector notes an approaching train and the moment the level crossing is closed to road traffic, i.e. the moment that the interlocking can lock a route across the level crossing. This equates to the time it takes to close the barrier (if present). Should be set to 0 if no barrier is configured. Useful for simulation.<br/>
Public duration
  typicalTimeToOpen
Details:
Notes: Average time between the time the deactivation is triggered and the moment the level crossing is open to road traffic, i.e. the moment that the level crossing reports open state. This equates to the time it takes to open the barrier (if present) and to deactivate road signals. Useful for simulation and timetable calculations.<br/>
Public duration
  constantWarningTime
Details:
Notes: A level crossing must cause as little as possible hindering to train as well as road traffic. Therefore, the level crossing must close as late as safely possible. The optimal delay, known as constant warning time, between activation and closing is possible when the train speed and position are known.<br/>
Public duration
  minimumOpenTime
Details:
Notes: This is the time the level crossing has to be open before it is allowed to close again. This is to ensure a certain capacity for the crossing road traffic.<br/>
Public duration
  maximumClosedTime
Details:
Notes: This is the time span after a message to the operator is triggered because a level crossing being closed for too long time can be considered as unsafe. In such cases the road drivers and pedestrians might try to cross the railway line illegally.<br/>
Public boolean
  requiresStopBeforeUnprotectedLevelCrossing
Details:
Notes: Flag to define whether any train needs to stop in front of the level crossing in case it is unprotected. Only afterwards it can proceed according the value in speedRestriction.<br/>
Tag Value
mixed false
Details:
Values: true | false
Default: false
Description: Determines whether this element may contain mixed element and character content.  Refer to the W3C XML Schema recommendation
modelGroup sequence
Details:
Values: all | sequence | choice
Default: sequence
Description: Overrides the package-level default model group
nillable false
Details:
Values: true | false
Default: false
Description: As defined by XML Schema specification
use required
