The Tygron Platform has special facility to include, visualize, modify, and use traffic data. Constructions have Function Values, can be updated in a variety of ways, and built-in Traffic Overlays use this data directly to perform spatial calculations. The entirety of all traffic data in a Project, and the rules dictating how traffic data changes through Actions taken in a Session, are collectively referred to as the Tygron Platform's traffic model.
Data
The Tygron Platform uses the following data sources to establish basic assumptions of traffic intensities:
- NWB (Nationaal Wegen Bestand)
- NSL Monitoring tool
- INWEVA 2015
In addition to these default assumptions, roads for which measured traffic intensities are known will have those default values overwritten with road-specific values from the following sources:
Function Values
- Main article: Function Value#Traffic
The data concerning traffic is, by default, available as Function Values and by extension as Attributes related to road-type Constructions in the 3D World.
Function Values related to traffic describe, for each road:
- Road-traffic intensities (such as buses, cars, trucks, and vans)
- Traffic intensities other that road-traffic (such as airplanes, bicycles, pedestrians, and ships)
- Speed limits and amount of lanes
- Jam factors for road-traffic
Grids
- Main article: Prequels (Traffic Overlay)
Other than traffic intensity values linked to specific Cosntructions in the 3D World, it is entirely permitted to store traffic data in other forms as well. Some of the Tygron Platform's built-in calculation models can make use of Prequels as their inputs.
Prequels can also make use of Function Value based data indirectly, by rasterizing the data using an Average Overlay.
Dynamic traffic data
Traffic data can also be computed dynamically, either completely based on the current state of the Project, or relatively, basing new traffic values on a set of original traffic values, and computing a change in traffic based on changes in the 3D World.
Calculations
- Main article: Traffic Overlay
Traffic data can be relevant for a wide range of calculations and use-cases. The Tygron Platform already contains several Traffic Overlays which compute the effects of traffic, on for example the topics of noise and NO2.
Traffic data, like any other Project data, can also be used in user-defined calculation models.
