Objects

Manage point and line objects within a project in the Objects section. Objects are used for monitoring and evaluation.

Object types

There are two main types of objects:

Point objects

Locations for traffic intensity, speed, and parking occupancy:

• Used for point evaluations
• Can be used in monitor and evaluation templates
• Can be composed to add carriageways or subtract exits
• Different object types: intensity (volume), speed, and occupancy (parking)

Line objects

Routes for travel time and flow:

• Used for line evaluations
• Can be used in monitor and evaluation templates
• Can be built from multiple segments
• Represents a route between two points

Creating a point object

1. Navigate to Project Configuration > Objects
2. Click “Create” in the Point Objects section
3. Fill in the form:
   • Object name: Give the object a clear name
   • Source: Select “NDW”, “Upload”, or “Parking” (if available)
   • Object type: Select “Intensity” or “Speed” (for NDW/Upload), or “Occupancy” (for Parking)
   • Measurement points / parking locations: Select one or more measurement points or parking locations on the left map
   • Display position: Click on the right map to set the position for display in templates
4. Click “Save”

Selecting a source

You can choose between the following sources for measurement points or parking locations:

• NDW: Use measurement points from the NDW (Nationale Databank Wegverkeersgegevens) system
• Upload: Use measurement points from an uploaded dataset (only available if the upload module is enabled)
• Parking: Use parking locations (only available if the parking layer is enabled). The object type is then Occupancy. Parking objects (occupancy) are intended for the Monitor only, not for Evaluation.

When you select “Upload”, you must also choose an upload set from the dropdown.

Selecting measurement points or parking locations

• Left map (Measurement points map): Shows available measurement points or parking locations depending on the selected source
  • Click measurement points or parking locations to add them to the object
  • For NDW/Upload: You can select multiple measurement points for composed point objects
  • For NDW: You can also manually enter an NDW measurement point ID via the text field below the map
• Right column: Shows all selected measurement points or parking locations
  • For intensity objects: Per measurement point you can switch between add (+) and subtract (-) via the toggle
  • Use this to add carriageways or subtract exits
  • You can remove measurement points or parking locations via the remove button

Setting the display position

• Right map (Location for display): Use this map to set the position where the point object is shown in templates
  • Click the desired location on the right map
  • This is especially useful for composed points or when measurement points are close together and you want to move the display position
  • If you select only one measurement point or parking location, the position of that location is used automatically

Creating a line object

1. Navigate to Project Configuration > Objects
2. Click “Create” in the Line Objects section
3. Fill in the form:
   • Object name: Give the object a clear name
   • Source: Select “NDW” or “Upload” (if available)
   • Object type: Select “Travel time” (already selected)
   • Line segments: Select one or more line segments on the left map to create a route
   • Display route: The right map shows the combined route for display in templates
4. Click “Save”

Selecting a source for line segments

You can choose between two sources for line segments:

• NDW: Use line segments from the NDW (Nationale Databank Wegverkeersgegevens) system
  • You can select travel time prefixes to show only certain segments (for example only segments that start with “RWS04”)
  • The prefix selection appears as a dropdown above the left map
• Upload: Use line segments from an uploaded dataset (only available if the upload module is enabled)

When you select “Upload”, you must also choose an upload set from the dropdown.

Selecting line segments and creating routes

• Left map (Line segments map): Shows all available line segments depending on the selected source
  • Click line segments to add them to the line object
  • You can select multiple line segments to create a route
  • The selected segments are combined into one route
  • For NDW: You can also manually enter an NDW line segment ID via the text field below the map
• Right column: Shows all selected line segments
  • You can remove line segments via the remove button
  • The order of segments determines the route

Overlapping line segments

When you click a location where multiple line segments are close together (within 50 metres and in the same direction), a table overlay appears automatically with all overlapping segments:

• The table shows all line segments within the tolerance
• Segments are filtered by direction - only segments going in the same direction as the clicked segment are shown
• Hover over a segment in the table to see a preview on the right map (green line)
• Click “Select” to add the desired segment to the line object
• Close the table by clicking the X button

This is useful when multiple segments overlap on the same road.

Display route

• Right map (Location for display): Shows the combined route of all selected line segments
  • This route is used for display in templates
  • The maps are synchronised - when you zoom or pan on one map, the other map moves with it

Editing an object

1. Find the object in the table
2. Click the edit button
3. Change the desired properties
4. Click “Save”

Deleting an object

1. Find the object in the table
2. Click the remove button
3. Confirm the removal

Note: Objects that are used in templates can be deleted. First remove the objects from templates where they are used, or delete the templates.

Objects tables

Point objects table

Shows all point objects with:

• Object name
• Object type (Intensity/Speed/Occupancy)
• Actions (edit/delete)

Line objects table

Shows all line objects with:

• Object name
• Actions (edit/delete)

Map view

The map on the right shows:

• Point objects: All configured point objects
• Line objects: All configured routes

Using objects

Objects are used in:

• Monitor templates: Select objects to monitor; see also Monitor configuration
• Evaluation templates: Select objects to evaluate; see also Evaluation configuration

Make sure all required objects have been created before you configure templates.
