Section 2: Concurrent Route Segments

Anchor: #i1011321

Concurrent Route Defined

Concurrent Routes are two or more highways designated over the same physical roadway. Concurrencies can exist at roadway gaps or at the beginning or ending of the highway. Add, update, or delete linked route segments like other point data (because they are stored as point data).

EXAMPLE: In Figure 9‑5, data for Highway A is interrupted by Highway B, but the designation of A is carried on the roadway segment along with B. For concurrent route segments, one route is the primary route (Highway B) and any others within the roadway segment are secondary routes (Highway A):

Figure 9-5. Concurrent segment of Highways A and B shaded.

Primary Route is the highest ranked highway system of all routes designated within the route segment:

  • If within the same highway system, the primary route segment has the lowest number of the other routes
  • All data values located within the link segment store with the primary route. This includes roadway mileage
  • It is also referred to as the Linking Signed Highway or Continuous Route.

Secondary Route is the other highway designated over the same route segment as the primary route:

  • It has no data attributes located on the route segment stored with it
  • Mileage within the route segment determines Distance From Origin and Distance Between Markers, but is removed for Federal mileage reports
  • It is also referred to as the Signed Highway or Interrupted Route.

System Response. While adding the new concurrency, the TRM system automatically:

  • Removes the gap record located in the TRM-Feature file for the interrupted route
  • Increases the:
    • mileage of the interrupted route by the length of the concurrent segment
    • distance from origin for all markers succeeding the new segment by the length of the new segment
    • distance between markers for the closest succeeding marker by the length of the new segment
  • Generates the To Marker location of the segment for the Signed Highway
  • Creates:
    • records in TRM for the begin and end points of the link
    • a new record with placeholder marker 9999 to mark the new ending of the Signed Highway, if the concurrency is added to the end of the route.

System Response. While deleting the concurrency, the TRM system automatically:

  • Creates a gap record in the TRM-FEATURE file within the Signed Highway at the marker location of what was the beginning of the concurrency
  • Decreases the:
    • mileage of the interrupted route by the length of the concurrent segment
    • distance from origin for all markers succeeding the new segment by the length of the new segment
    • distance between markers for the closest succeeding marker by the length of the new segment
  • Removes records in TRM for the begin and end points of the link for both routes
  • Creates a new record with placeholder marker 9999 to mark the new ending of the Signed Highway, if the concurrency is deleted from the end of the route.
