Loading in GeoJSON

In this assignment you will load in a GeoJSON file into the editor. A file has been prepared with a number of shapes which overlap with some of the roads in the project. The file also contains (fictional) traffic intensity values. By loading in this file into the editor, the building values of the roads can be adjusted to have the traffic intensities as defined in the file.

Download the excample traffic intensities file. It can be found here: Road Intensity file. Unpack it before starting.

Loading traffic intensities:

1. Drag the GeoJSON file into the editor.
2. Select "Import Building Values".
3. Select "only buildings with Category: ROADS".
4. Make sure "TRAFFIC_FL" is checked.
5. Enter "TRAFFIC_FLOW" in the field next to "TRAFFIC_FL".
6. Select "Send".

To see the loaded traffic intensities, it is possible to simply view the roads in the 3D world. The affected roads will have more cars on them then they had before. For greater insight into the effects of the new data, it is also possible to add an overlay for traffic noise or traffic intensity.
