Section 4: Adding Non-Contiguous Segments

Anchor: #i1020699

Non-Contiguous Route Defined

A Non-Contiguous Route segment is a designated highway section which, when added, does not adjoin a route segment already existing in TRM, but is located on the proposed alignment of the completed route. Add this new section due to new construction or route realignment. The new non-contiguous segment may join an existing route:

  • Before the beginning of the route
  • After the ending of the route
  • Within a roadway gap within the route.
Anchor: #i1020728

Input—Before Beginning of Route

Input only the ‘From’ Reference Marker Number, which resides on the new segment; add it to the route without going through the Add Reference Markers process.

Determining the length of the new segment requires both the ‘From’ and ‘To’ Displacement fields (see Figure 5‑6 below):

  • The ‘From’ Displacement is the distance from the given marker to the beginning of the new segment. This becomes the new beginning of route. This marker should not be at the exact beginning of the new segment
  • The ‘To’ Displacement is the distance from the given marker to the ending of the new segment. This becomes the location of the beginning of a new roadway gap

The calculated length of the new segment is the difference between the ‘From’ Displacement and the ‘To’ Displacement.

Do not input the ‘To’ Reference Marker Number; it is automatically the same as the ‘From’ Reference Marker Number

  • (+) or (Blank) To Reference Marker Sign and Displacement

System Response. While adding this new non-contiguous segment, the TRM system automatically

  • Creates a record with placeholder marker 0000
  • Adjusts:
    • DFO for all existing markers as needed
    • Distance between markers for all existing markers as needed
  • Copies the value of District-Id into the Maintenance District field.

Input—After End of Route

Input only the ‘From’ Reference Marker Number, which resides on the new segment; add it to the route without going through the Add Reference Markers process.

Determining the length of the new segment requires both the ‘From’ and ‘To’ Displacement fields (see Figure 5‑7 below):

  • The ‘From’ Displacement is the distance from the given marker to the beginning of the new segment. This becomes the location of the ending of a roadway gap
  • The ‘To’ Displacement is the distance from the given marker to the ending of the new segment. This becomes the new ending of route

The calculated length of the new segment is the difference between the ‘From’ Displacement and the ‘To’ Displacement.

  • Creates a record with placeholder marker 9999

    • DFO for all existing markers as needed
    • Distance between markers for all existing markers as needed
  • Copies the value of District-Id into the Maintenance District field

Input—Within Roadway Gap

This procedure leaves the existing route with a roadway gap on either side of the new segment. Input only the ‘From’ Reference Marker Number, which resides on the new segment; add it to the route without going through the Add Reference Markers process.

Determining the length of the new segment requires both the ‘From’ and ‘To’ Displacement fields (see Figure 5‑8 below):

  • The ‘From’ Displacement is the distance from the given marker to the beginning of the new segment. This becomes the location of the ending of a roadway gap.
  • The ‘To’ Displacement is the distance from the given marker to the ending of the new segment. This becomes the location of the beginning of another roadway gap

The calculated length of the new segment is the difference between the ‘From’ Displacement and the ‘To’ Displacement.

System Response. While adding this new non-contiguous segment, the TRM system automatically:

  • Creates an additional roadway gap record in the TRM-FEATURE file at the ending of the new segment. The original gap record remains as it was
  • Adjusts:
    • DFO for all existing reference markers past the new segment as needed
    • Distance between markers for all markers past the new segment as needed
  • Copies the value of District-Id into the Maintenance District field.
