Adding references to linear equipment

Add linear references to linear equipment records. A linear reference is a point or line along a linear equipment record and serves as a reference point.

Note: If two linear equipment records intersect, you must define the point of intersection as a linear reference on each equipment record. For example, if Main St. and Washington Ave. intersect, define Main St. as a linear reference on Washington Ave.’s equipment record and define Washington Ave. as a linear reference on Main St.’s equipment record. If you do not define the point of intersection as linear references on both equipment records, the system will calculate linear distance incorrectly when searching for equipment.

To add references to linear equipment:

  1. Select one of these options:
    • Equipment > Assets
    • Equipment > Systems
    • Equipment > Positions
  2. Select the asset, system, or position for which to add a linear reference, and then click the Linear References tab. The system automatically populates Equipment Length and the unit of measure in the adjacent field.
  3. Click Add Reference.
  4. Specify this information:
    Type
    Select one of these options:
    Option Description
    Linear reference system Select to indicate that this reference denotes the measurement system by which to locate a point, line, or piece of equipment along the linear equipment record. Mile markers on an interstate are one example.
    Related equipment Select to indicate that this reference denotes equipment that is located along the linear equipment record. Exit ramps along an interstate are one example.

    Related equipment must be specified to display the reference on the map on the Linear Overview tab.

    Note: If you select Related equipment, the system enables Equipment.
    Point of interest Select to indicate that this reference denotes any point along the linear equipment record that is important to track, but is not defined as an equipment record within the system. Road signs are one example.
    Note: Reference types are linked to the LRTP entity for which you must define your reference type codes. Depending on your system configuration, the codes listed below are not the codes that appear in the dropdown. Contact your system administrator for more information.
    Class
    Specify the class of the linear reference. This is required for the linear reference to display on the map on the Linear Overview screen.
    Equipment
    Specify the equipment record to add as the reference if you selected Related equipment as the Type. The system automatically populates Ref. Description, Equipment Org., and Geographical Reference.
    Ref. Description
    Specify a description of the reference.
    From Point
    Specify the point on the linear equipment record from which to begin the reference.
    To Point
    Specify the point on the linear equipment record to end the reference.
    Geographical Reference
    Specify a geographical reference point for the reference.
    Inspection Direction
    Specify the typical direction in which an equipment inspection is performed.
    Flow
    Specify the typical direction in which the process flows.

    For example, you can specify the traffic direction of a street or the direction in which oil flows through a pipe.

    Apply to Children
    Select this check box to have the linear references of this record applied to all of the child records.
    Point Reference
    Select this check box if the linear reference is a single point. For example, a signal light on a track would be a Point Reference that exists at one specific place. After you click the check box, the To Point is updated to match the From Point.
    Apply to Route/ROW
    Optionally, select this check box to apply the linear reference to a route or right of way.
  5. Select the Display on Overview check box to display the reference on the map on the Linear Overview tab.
  6. Click Submit.
