How to add traffic data unaligned with roads
Traffic data can be important in many use-cases. However, traffic data can also be notoriously difficult to align to geographical features exactly, due to the conceptual nature of the data in relation to the physical properties of the built environment. The Tygron Platform provides a mechanism which allows traffic data to be loaded in separate from the Buildings in the project, after which calculation models which rely on traffic data can use that data 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.
- Open the Geo Data Wizard.
- Opt to import data as Areas.
- Select the data source of traffic you intent 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 to 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.
