Traffic data can be important in many use-cases. However, traffic data can be challenging to align exactly to geographical features, due to the conceptual nature of the data in relation to the physical properties of the built environment. Tygron Platform allows traffic data to be loaded separately from Buildings, enabling calculation models to use it as input.
These steps assume the data is available as vector data, either polygons or lines. Though the principle is similar, the steps for importing grid-based data are slightly different.
How to load add traffic data unaligned with roads:
- Open the Geo Data Wizard.
- Opt to import data as Areas.
- Select the data source of traffic you intend to import (if it's a file, select the file. If it's a server, select the server, etc).
- Opt to import the data as new Areas.
- Continue through the rest of the wizard as normal, selecting the appropriate name and desired Attributes.
- Take special note of the Attribute which holds the traffic intensities data, for a later step.
- Finish the wizard so that the Areas are added to the project.
- Add an Average Overlay.
- Set the Average Overlay to look for the previously noted Attribute for traffic intensities.
- Set the averaging distance to 0.
- The created Average Overlay can now be used as a Prequel for a Traffic Overlay or other Grid Overlay.
