7.8.4.79.3 Properties
| Name | Property Type | Data Type | Description | |
|---|---|---|---|---|
| ApproachSpeed | IfcPropertySingleValue | IfcLinearVelocityMeasure |
The design speed of trains approaching the signal if different from the line speed. |
|
| MarkerType | IfcPropertyEnumeratedValue | PEnum_MarkerType |
The type of marker (sign) e.g. stop signal, restriction signal, track circuit tuning zone sign or others specified in PEnum_MarkerType. |
|
| NominalHeight | IfcPropertySingleValue | IfcPositiveLengthMeasure |
The nominal height of the object. The size information is provided in addition to the shape representation and the geometric parameters used within. In cases of inconsistency between the geometric parameters and the size properties, provided in the attached property set, the geometric parameters take precedence. The nominal height of the furniture of this type. The size information is provided in addition to the shape representation and the geometric parameters used within. In cases of inconsistency between the geometric parameters and the size properties, provided in the attached property set, the geometric parameters take precedence. |
|
| Symbol | IfcPropertyReferenceValue | IfcExternalReference |
Content which is shown on the sign, e.g. text, number, arrow or icon. The string can also be a pointer to a symbol catalog. |
|
| NominalWidth | IfcPropertySingleValue | IfcNonNegativeLengthMeasure |
The nominal overall width of the object. The size information is provided in addition to the shape representation and the geometric parameters used within. In cases of inconsistency between the geometric parameters and the size properties, provided in the attached property set, the geometric parameters take precedence. |
