Adding point events to dominant routes

The Event Editor allows you to add point events to dominant routes in case route concurrences exist.

Concurrent routes

Concurrent routes are routes that share the same centerlines; that is, they travel the same pavement but are modeled with different measures. This relationship may have been created to model two separate routes with different directions of calibration, to model different directions of travel on the highway, or to model locations on highways where multiple routes converge into a common roadway for a subset of their paths. In the locations where these concurrences exist, you can choose a route that is considered dominant using a set of rules. For more information on setting up route dominance, see Configuring route dominance.

The Event Editor app allows you to add point events to the dominant routes. For example, in the following graphic, there are three routes with route IDs: 100 with Name A, 200 with Name B, and 300 with Name B. The concurrent routes have different ranges in time.

Route dominance

The route dominance rule is set as the lesser the Route Name, the more dominant the route. Using this condition, route 100 is the most dominant route, and routes 200 and 300 have the same order in dominance.

Route dominance rules

Say you want to add point events at three locations on route 200. In Location 1, route 200 is the dominant route, since no other route exists at that point. Therefore, the event will be added to route 200. In Location 2, route 100 has a greater order of dominance; therefore, the event will be added to route 100. In Location 3, both route 200 and route 300 have the same order of dominance; therefore, the event will be added to the route of your choice.

Note:
  • Route dominance rules should be configured to access this functionality.

Complete the following steps to add point events to dominant routes:

  1. Open Event Editor and, if prompted, sign in to Portal for ArcGIS or ArcGIS Online.
  2. Click the Edit tab.
  3. In the Edit Events group, click the Point Events button Point Events.

    The Add Point Events widget appears.

    If there are no editable point event layers, the widget is disabled.

  4. Choose an event layer you want to edit from the Event Layer drop-down list.

    The point event will be added to this layer.

  5. Click the Network (LRM) drop-down arrow and choose the network that will serve as a source LRM for defining the input measures for the new events.

    The Network (LRM) is an LRS Network published as a layer in the Event Editor.

    You can specify the LRS Network to be used as the LRM for defining the measure of the new point event.

  6. Type the route's Route ID on which the event's measure will be located.
    Tip:

    You can also click the Select a Route on the Map button Select a Route on the Map to choose the route on the map.

  7. In the Location section, choose the first option (with the suffix Network) in the Method drop-down menu.
  8. Provide the intended location for the new point event along the route using any of the following options:
    • Type the value in the Measure text box.
    • Click the Select From Measure on the Map button Select From Measure on the Map and choose the measure value along the route on the map.
    • Click the Measure drop-down arrow to choose either Use the Route Start or Use the Route End option as the measure value for the event.

    If you type the measure value, you can choose the unit for that value using the drop-down arrow. The measure value will be converted into LRS units before saving the newly added events. For example, the LRS is in miles and if you type 528 feet as the measure value, the newly added event will have a measure value of 0.1 miles, because 528 feet equals to 0.1 miles.

    A red cross appears at the selected location on the map.

  9. Choose the date that will define the start date of the events by doing one of the following:
    • Click the Start Date drop-down arrow to choose the start date using a calendar.
    • Check the Use route start date check box to use the start date of the routes.

    The start date defaults to today's date, but you can choose a different date using the date picker. The end date is optional, and if it's not provided, the event remains valid now and into the future.

  10. Choose Prevent measures not on route to prevent erroneous input while characterizing a route with point events.

    This data validation option ensures that the input measure value falls within the minimum and maximum range of measure values on the selected route.

  11. Check the Save events to dominant routes check box.

    This option can be configured to be checked or unchecked by default using the Event Editor's configuration file. For more information, see Configuring the Event Editor web application.

  12. Click Next.

    The route dominance table appears.

    The Route ID and Measure columns show the values for each dominant route where the events will be added.

    As an example, route 200 has a From Date value of 1/1/2000, and route 100 and route 300 have a From Date value of 1/1/2010. Therefore, if you choose 1/1/2000 as the start date of the event, there will be two time ranges:

    • 1/1/2000–1/1/2010, when only route 200 existed.
    • 1/1/2010–Null, when all three routes existed.

    A black route ID without a drop-down arrow signifies that there was a single route in that location. A blue route ID with a drop-down arrow signifies that there are concurrent routes in that location, and the blue route is chosen by the software based on the route dominance rules. You can choose any other route using the drop-down arrow.

    A yellow route ID box with a drop-down arrow signifies that there is an ambiguous situation (Location 3, for example) in choosing the dominant route, as there is a tie in the route names of route 200 and route 300. In this case, you need to manually choose a route ID using the drop-down arrow. The yellow disappears once you've manually chosen a route.

    Choosing a route manually

    In this example, you would choose route 300. The Measure value along route 300 is the measure of that route at the same location in the separate time range.

  13. Click Next to view the Attribute-Value table.

    This table contains all the attributes of the event layer.

    Event attribute table
    Note:

    Coded value, range domains, and subtypes are supported when configured for any field in the Attribute-Value table.

  14. Provide attribute information for the new event in the table.
  15. Check the Show network name check box to see with which LRS Network the selected event layer is associated.
  16. Click Save.

    A confirmation message appears in the bottom right once the newly added point event is saved. The new point is created and displayed on the map.

After an event has been successfully created, you have the following two options to continue characterizing the route:

  • When you click New Edit, all the input entries in the widget are cleared, and the default values from the geodatabase are populated in the attribute table.
  • When you click Next Edit, all the existing entries in the widget and the attribute table are retained for the convenience of quick editing of similar characteristics.
