Reassigning a route

Routes must be reassigned when their designation changes but the construction of the highway does not. Where a retirement indicates that a portion of a route simply went away, a reassignment indicates that the portion of the route actually became part of a different route. This is important because, while event data tends to be linked to a specific route identifier, the events themselves are more appropriately linked to the actual pavement they fall on. One example of a route reassignment is when administrative boundaries change and you need to redesignate the portion that now falls on the wrong side of the boundary. Another example could be when your business rules prohibit overlapping routes, which creates gaps where two or more routes would otherwise share pavement, but you want to change which route has the gap and which does not.

Steps:

1. Start ArcMap and set up your editing environment for using Roads and Highways.
2. Use the ArcMap navigation controls to zoom to the route portion you want to reassign.
3. Set your target LRS Network layer.
4. Set your Activity Type to Reassign Route.
5. Click the Apply button .

   The Reassign Route dialog box appears.

   
6. In the Parameters area, enter an effective date for the reassignment.
   • Manually enter a date in the Effective Date field. Acceptable date formats include D/D/YY, DD/DD/YY, or DD/DD/YYYY.
   • Use the Calendar control drop-down menu to enter an effective date.
7. Enter a route ID:
   • Manually enter a route ID.
   • Use the Select Location tool to select the route you are going to reassign to another route.
8. Enter a From Measure:
   • Manually enter a From Measure.
   • Use the Select Location tool to click the From Measure of the route portion you want to reassign.
9. Enter a To Measure:
   • Manually enter a To Measure.
   • Use the Select Location tool to click the To Measure of the route portion you want to reassign.
10. Choose whether you want to recalibrate the remainder of the reassigned route downstream of the reassigned portion.
    • Check Recalibrate route downstream to recalibrate the remainder of the reassigned route downstream of the reassigned portion.
    • Uncheck Recalibrate route downstream if you do not want to recalibrate the remainder of the reassigned route downstream of the reassigned portion.
11. Choose whether you want to use the whole route in the reassignment.
    • Check Use whole route if you want to reassign the entire route.
    • Uncheck Use whole route if you want to reassign only a portion of the route.

    If you opt to use the whole route, the From Measure and To Measure will automatically populate with the From and To Measures of the reassigned route.

12. In the Reassign Values frame, enter a route ID:
    • Manually enter a route ID.
    • Use the Select Location tool to select the route you are going to reassign to another route.
13. Enter a From Measure of the target route reassignment location:
    • Manually enter a From Measure.
    • Use the Select Location tool to click the From Measure of the route portion you want to reassign.
    • If you do not know the From Measure, you can let Roads and Highways suggest the From Measure. The From Measure is calculated as the source geometry length minus (-) the To Measure.
      1. Enter a parameter To Measure.
      2. Click Calculate.
    Note:

    • If you are filling a gap, this value will be equal to the measure at the beginning of the gap.
    • If you are adding the reassigned route to the end of the target route, this value will be equal to the end measure of the target route.
    • If you are creating a new route or adding the reassigned portion to the beginning of the target route, this value will be equal to the new starting measure of the target route.

14. Enter a To Measure of the target route reassignment location:
    • Manually enter a To Measure.
    • Use the Select Location tool to click the To Measure of the route portion you want to reassign.
    • If you do not know the To Measure, you can let Roads and Highways suggest the To Measure. The To Measure is calculated as the source geometry length plus (+) the From Measure.
      1. Enter a parameter To Measure.
      2. Click Calculate.
    Note:

    • If you are filling a gap, this value will be equal to the measure at the end of the gap.
    • If you are creating a new route or adding the reassigned value to the end of the target route, this value will be equal to the new end measure of the route.
    • If you are adding the reassigned route to the beginning of the target route, this value will be equal to the total length in linear referencing method (LRM) measure units of the reassigned portion.

15. Choose whether you want to recalibrate the remainder of the reassigned route downstream of the reassigned portion.
    • Check Recalibrate route downstream to recalibrate the remainder of the reassigned route downstream of the reassigned portion.
    • Uncheck Recalibrate route downstream if you do not want to recalibrate the remainder of the reassigned route downstream of the reassigned portion.

    The Reassign Route dialog box is fully populated.

    
16. Click OK.

    The portion of the reassigned route has now been added to the target route.
