Adding point events by route and measure

Events on a route, such as crashes and traffic count sites, can be represented as single point events with measure information along the route. The Add Point Events widget allows users to create new point events.

Note:

If the event ID field in the event layer is not a String data type (minimum 32-character length), the Roadway Characteristics Editor (RCE) will not provide an event ID and will not support editing that event. It’s important to model internal events with an event ID. For more information, see Overview of the Roadway Characteristics Editor deployment guide.

1. Open a web browser and browse to the Roadway Characteristics Editor.
2. On the Edit tab, in the Edit Events group, click Point Events.

   

   The Add Point Events dialog box appears.

   

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

3. Select an event layer you want to edit from the Event Layer drop-down list.
4. Select the Network (LRM) that will serve as a source for providing the measure for the new point event.

   The widget accepts an LRS Network as a source to identify the location for adding the new point event. However, when the new point event data is being stored in the database, the application performs an internal translation of measures to always store the measure value in the linear referencing method of the LRS Network with which the event is registered.

The Network (LRM) value can be a published LRS Network layer.
5. Type a route ID in the Route ID text box on which the new event measure will be based, or use the Select a Route on the Map tool to pick the route from the map.

   The selected route is highlighted on the map.

   

   Note:

   If a message appears that is related to acquiring locks, the need to reconcile, or not being able to acquire locks, Roads and Highways conflict prevention is enabled. For more information about these messages, see Conflict prevention in the Roadway Characteristics Editor.

   Use the Select a Redline on the Map tool to create a point event on a redline. To learn more, see Adding point events to a route redline.

6. In the Location section, type the measure value of the intended location for the new point event along the route in the Measure text box, or use the Select From Measure on the Map tool to pick the route location on the map.

   The new event will be associated with the route (route ID) from the LRS Network that the event location intersects. In cases where the input location intersection may have more than one route in the registered LRS Network (overlapping routes), a dialog box prompts you to choose which route you prefer the event to be associated with.

   A red cross symbol is dropped at the selected location on the map.

7. Using the Start Date and End Date calendar controls, choose the start and end dates of the event.

   The start date defaults to today's date, but you can select a different date using the date picker. The end date is optional.

8. The Prevent measures not on route check box is checked by default.

   This data validation option ensures that the measure values typed in step 6 fall within the minimum and maximum range of measure values on the selected route.

9. Click Next to view the Attribute-Value table. This table contains all the attributes of the event layer. Fill out all the attribute information for the new event in this table. Check the Show network name check box to see which LRS Network the selected event layer is associated with.

   

10. Click Save.

    The new point is created and displayed on the map.

11. After a point event has been successfully created, you have two options to continue characterizing the route:
    • When you click New, all the input entries in the form are cleared, and the default values from the geodatabase are populated in the attribute table.
    • When you click Next, all the existing entries in the form and the attribute table are retained for the convenience of quick editing of similar characteristics.
