Before you can monitor travel time data in the Travel Times Engine, you must add nodes to your traffic network. Nodes are roadside detectors and segment endpoints that gather data for the Travel Times Engine. Nodes can serve several different functions in the calculation of travel times, such as being the source or destination used in these calculations.

Before you begin

Create a traffic network.

What you should know

Creating passive nodes using data providers other than Google Maps and Azure Maps might require configuration steps that are not documented in this guide.

Procedure

  1. From the Travel Times Engine web page, hover over the Admin menu, and select Nodes.
    The Nodes page is displayed.
  2. Hover over the Nodes menu and click Add node ().
  3. Select your device Model or node type.
    NOTE: For list of device models, see Supported node models in the Travel Times Engine.
  4. Configure your node properties:
    Short Name
    Enter a name for the node.
    Best Practice: Include the geographic location of the node. For instance, the street name, direction, and intersecting street.
    Description
    Enter a description for the node. This can match or provide more details related to the information entered in the Short Name
    Active
    Clear the check box to deactivate the node. It is activated by default.
    Owning Travel time organization
    Select the Travel time organization that owns the node.
    Traffic network
    Select the traffic network where your node is found.
    Time zone
    Select the time zone where your node is found.
    Display Order
    Set a number to determine where in the Nodes list the node is displayed.
    Detector ID
    Set the ID of the detector. The detector ID in the detector must match the detector ID of the node. This informs the system which detector a detection is coming from.
    NOTE: For passive nodes, this value can be random.
    Additional copies
    Create copies of the node with the same configuration.
    Sends timestamps
    If enabled, the node sends timestamps. If disabled, the system ignores GPS data and locks the location of the node.
    Sends location
    If enabled, the node sends GPS location data. If disabled, the Travel Times Engine uses the system's timestamps.
    Sends location
    If enabled, the node sends timestamps. If disabled, the system ignores GPS data and locks the location of the node.
    Expected send frequency
    If the system does not receive data from the node for the time period set here, the system considers the data to be stale, and the node to be disconnected.
    NOTE: A value of zero means that the system never considers the node as failed due to lack of data.
    Voltage warning level
    If the node is battery powered and its battery level goes below the value set here, then the system considers the device's battery to be low.
  5. Click OK.
  6. (Optional) To be able to configure the type of vehicle that the node monitors, hover over the General menu, click Change general settings (), and set the Classification type for the node.
  7. From the Node details page, hover over the Location menu and click Change location ().
  8. Assign a location for the node by dragging the () icon on the map, or entering the node's Latitude and Longitude coordinates.
    Tip: If you are using passive nodes and a third-party API, avoid placing your node at an overpass or an intersection.
  9. (Optional) In the Corridor field, enter a corridor name.
  10. Click OK.

After you finish

  • Create at least one additional node.
  • After you have two or more nodes in your traffic network, create traffic links.
