The following is a summary of the steps TRM Users take to inventory a new route and input to TRM:

Anchor: #i1002478Establishing A Route




The district office drafts the construction plans. These plans contain at least one reference marker and its displacement from the beginning of the route to the ending of the route. To establish this marker number, the district office contacts its TPP TRM analyst indicating:

  • the geographical location of the new route
  • the location in miles from the beginning of the route to the new marker
  • the overall route direction (north to south, west to east, etc).

The TPP TRM analyst then determines the numeric value of the one marker.


TPP receives the construction plans. In the past, TPP received only the as-built final plans after the roadway was built. TPP now receives the initial construction plans to inventory before the district completes construction


TPP determines the network characteristics of the route diagrammed in the plans and enters these into TRM:

  • The route alignment using the one reference marker from the plans
  • The roadbed configuration of the route or route segment
  • Any other roadway data which can be collected from the plans, such as curves, bearings, administrative-related data, etc.


The TPP TRM analyst informs the district TRM coordinator when he/she adds the route to TRM and that the route is now ready for district data input


District enters data to TRM. At this time, the route is considered under construction


District completes route and makes a final review of the data entered to TRM. Once they validate all data, the district sets the Highway Status to 5—Open to traffic, all district data entered


TPP enters any remaining data. TPP makes all final adjustments to the data and then sets the Highway Status to 6—Open to traffic, all data entered. The route is now considered officially open for traffic.
