5. Click on desired map position to spawn vehicle.

6. If click point contains multiple lanes and 'Use lane heading' is checked, a dialog box will appear and ask to select lane ID to use for lane heading.

   

7. If click point contains lanes with multiple elevations, a dialog box will appear and ask to select the desired elevation.

   

Note: Sometimes there will be a "Click point too far from lane" error. Try choosing a different elevation.

Note: Currently you can insert vehicle one at a time.

Note: You can toggle labels on and off by clicking on the 'Label' button

Adding Pedestrians

3. If 'Use random pedestrian' is checked, a random pedestrian type will be selected for every spawned pedestrian.

   

4. Press on 'Insert', mouse pointer will change to cross-type pointer.

5. Click on desired map position to spawn pedestrian.

6. If click point contains multiple lanes and 'Use lane heading' is enabled, a dialog box will appear and ask to select lane ID to use for lane heading.

   

7. If click point contains lanes with multiple elevations, a dialog box will appear and ask to select the desired elevation.

   

Note: Sometimes there will be a "Click point too far from lane" error. Try choosing a different elevation.

Note: You can insert as many pedestrians as you desire after pressing on 'Insert'

Note: You can toggle labels on and off by clicking on the 'Label' button

Removing Vehicles or Pedestrians

1. In Layers right click on layer and select Open Attribute Table.
