Create a route

Disponible avec la licence Location Referencing.

Routes are created in an LRS Network using centerline features that define the location and geometry of a route.

The centerline features used to create routes can exist in the centerline feature class, be digitized into the centerline feature class (using aerial photography or other basemaps for guidance), be copied and pasted from other feature classes, or be imported from CAD files or other ArcGIS-supported data sources.

Remarque :
  • The centerline and network feature classes must be present on the map to run this tool.
  • An additional attribute table appears in the Create Route pane if your network feature class has extra fields. You can type a route name here if your network is configured to use a user-generated route ID.
  • Gap calibration rules are followed when creating routes.
  1. Ajoutez la classe d’entités d’axes médians et de réseau à une carte.

    Vous pouvez également ouvrir une carte dans laquelle la classe d’entités d’axes médians et de réseau est toujours présente.

    Remarque :

    Le modèle d’informations n’attend qu’un axe médian à un emplacement donné. Assurez-vous que les axes médians utilisés pour votre mise à jour ne chevauchent pas d’autres axes médians de votre réseau LRS.

    Remarque :

    Généralement, les réseaux versionnés doivent être mis à jour par l'intermédiaire d'une connexion directe à la géodatabase. Les réseaux de branche versionnée, notamment ceux configurés avec un ID d’itinéraire généré par l’utilisateur, doivent être mis à jour par l’intermédiaire d’un service d’entités.

  2. Zoom in to the location where you want to create the route.
    Remarque :

    The centerline features for the route must exist in the centerline feature class before creating the route.

    Conseil :

    To change the display field shown in the centerlines table, right-click the centerline feature class in the Contents pane and choose Properties from the context menu. On the Layer Properties dialog box, click the Display tab, and click the Display field drop-down arrow to change its value. In the previous image, the display field is OBJECTID.

  7. Choose the network to which you want to add a route in the Network drop-down list.
    Remarque :

    Pour mettre à jour via les services d’entités, il est nécessaire de publier le réseau LRS en activant les fonctionnalités de référencement linéaire et de gestion des versions.

    Depending on the network configuration you are using, you may have a multifield route ID to enter. If that's the case, the Create Route pane appears with Route ID Attributes to configure attributes.

  8. Provide a Route ID value.

    The route ID must be unique for the chosen network. If you're using a multifield route ID, create the route ID by selecting or entering values for the fields that comprise the route ID. This is configured using the Create LRS Network From Existing Dataset tool.

    The screen shot above shows Route ID Attributes with attributes that are used to create the route ID.

  9. Click the Calendar button Calendrier next to Start Date to choose a start date for the route.
    Conseil :

    You can also double-click the Start Date text box to automatically populate it with today's date, or type a date in the Start Date text box.

  10. Type a value in the From Measure text box. The default is 0.000.

    If you don't know the From Measure value, you can do the following to calculate one by subtracting the geometrical length of the centerline from the To Measure value:

    1. Type a value in the To Measure text box.
    2. Click the Recalculate From Measure button Recalculer la mesure d’origine next to the From Measure text box.
  11. Update the To Measure value if necessary.

    The To Measure value is automatically populated with the geometric length of the chosen centerline by default.

    Remarque :
    • Z-values are considered when calculating the geometric length of the centerlines.
    • Centerlines and routes support z-values..

    If you don't know the To Measure value, you can do the following to allow Location Referencing to calculate one by calculating the count of the To Measure value and From Measure value:

    1. Update the From Measure value if necessary.
    2. Click the Recalculate To Measure button Recalculer la mesure de destination next to the To Measure text box.
  12. Fill in additional field attributes in the network feature class as necessary.

    The attribute fields in the Create Route pane support coded value and range domains. This is helpful when you want to limit attribute values to a predefined list or range of values.

  13. Click Run.
    Remarque :

    If your route edit will result in the introduction of one or more physical gaps on the route, a prompt appears to alert you before the tool is run. If you didn't plan to create a gapped route, answer No and edit your digitized centerlines so that no gaps result during route editing.

    If the route being edited already had one or more physical gaps, and no additional physical gaps were introduced by the edit, no prompt will appear.

    You can prevent unplanned centerlines by enabling snapping in the active map, or by enabling snapping using the Edit tab, Snapping group, Snapping button Répertorier par capture.

    You can disable this warning by unchecking Warn before allowing route edits that can create physical gaps in Location Referencing options.

    Conseil :

    Click Identify Routes Identifier des itinéraires on the Location Referencing tab and select the new route on the map to view details about it.

    Remarque :

    You can keep the centerlines chosen after creating the route.

Complex route creation scenarios

The following sections provide examples of complex route creation, including loop, lollipop, branch, alpha, barbell, and infinity routes:

Create a loop route

In the following example, four centerlines (CL1, CL2, CL3, and CL4) are used to create a loop route:

Example 1: Four centerlines are used to create a loop route

Calibration points are added at the start of the loop (0), end of the loop (10), and at a third (3.33) and two-thirds of the loop (6.67).

Example 1: The output is a loop route with four calibration points

Create a lollipop route

In the following example, two centerlines (CL1, CL2) are used to create a lollipop route:

Example 1: Two centerlines are used to create a lollipop route

RouteX is created with calibration points at the start of the stick portion (0), the end of the loop portion (12), and at a third (5.33) and two-thirds of the loop portion (8.67).

Example 1: A lollipop route is created with four calibration points

In the second example, two centerlines (CL1, CL2) with different directions compared to the example above are used to create a lollipop route.

Example 2: Two centerlines are used to create a lollipop route

RouteX is created with calibration points at the start of the loop portion (0), at a third (3.33) and two-thirds of the loop portion (6.67), and in the stick portion (12) at the end of the lollipop.

Example 2: A lollipop route is created with four calibration points

Create a branch route

In the following example, two centerlines (CL1, CL2) are used to create a branch route:

Example 1: Two centerlines are used to create a branch route

RouteX is created with calibration points at the start of the branch, the end of the branch, and at the start and end of an imaginary branch edge.

Example 1: A branch route is created with four calibration points

In the second example, two centerlines (CL1, CL2) are used to create a branch route.

Example 2: Two centerlines are used to create a branch route

RouteX is created with calibration points at the start of the branch, the end of the branch, and at the start and end of an imaginary branch edge.

Example 2: A branch route is created with four calibration points

Create an alpha route

In the following example, three centerlines (CL1, CL2, CL3) are used to create an alpha route:

Example 1: Three centerlines are used to create an alpha route

RouteX is created with calibration points at the start (0) and end (16) of the alpha portion, and at a third (6.33) and two-thirds (9.67) of the loop portion.

Example 1: An alpha route is created with four calibration points

Create a barbell route

In the following example, three centerlines (CL1, CL2, CL3) are used to create a barbell route:

Example 1: Three centerlines are used to create a barbell route

RouteX is created with calibration points at the start (0) and end (18) of the barbell, and at a third (2.67 and 12.67) and two-thirds (5.33 and 15.33) of each loop portion.

Example 1: A barbell route is created with six calibration points

Create an infinity route that starts and ends at an intersection

In the following example, one centerline (CL1) is used to create an infinity loop route that starts and ends at an intersection:

Example 1: One centerline is used to create an infinity route

RouteX is created with calibration points at the start (0) and end (20) of the infinity route, and at a third (3.33 and 13.33) and two-thirds (6.67 and 16.67) of each loop portion.

Example 2: One centerline is used to create an infinity route

In the following example, one centerline (CL1) is used to create an infinity loop that starts and ends on a loop:

Example 2: One centerline is used to create an infinity route

RouteX is created with calibration points at the start (0) and end (10) of the infinity route, and at the middle (1.25 and 8.75) of every path in the primary loop, and at a third (4.17) and two-thirds (5.83) of the secondary loop.

Example 2: An infinity route is created with six calibration points

Create a route in a line network

The following examples show route creation in a line network.

In the first example, there are two existing routes on a line, R1 and R2. A new route, R3, is created by selecting CL1 at the beginning of the existing routes on the line. Consequently, the line order is updated for the existing downstream routes R1 and R2.

Example 2 Output: A new route, R3, is created by selecting CL2 in the middle of existing routes in a line.

In the third example, there are two existing routes on a line: R2, and a gapped route, R1. CL2 is located inside the R1 gap. A new route, R3, is created by selecting CL2 in the middle of the existing routes on the line. Consequently, the line order of the existing downstream route R2 is updated to 300. The line order of the upstream route, R1, remains the same.
