== What is a Traffic Model ==
''From Wikipedia, the free encyclopedia''
 
: A traffic model is a mathematical model of real-world traffic, usually, but not restricted to, road traffic. Traffic modeling draws heavily on theoretical foundations like network theory and certain theories from physics like the kinematic wave model. The interesting quantity being modeled and measured is the [[Traffic Flow (Overlay)|traffic flow]], i.e. the throughput of mobile [[units]] (e.g. vehicles) per time and transportation medium capacity (e.g. [[Constructions#Roads|road]] or lane width). Models can teach researchers and engineers how to ensure an optimal flow with a minimum number of traffic jams.
 
: Traffic models often are the basis of a traffic simulation.
 
== How does a Traffic Model relate to the Tygron engine? ==
: To better visualize traffic and its impact, for planning purposes in the Tygron Engine, three traffic aspects are simulated: Traffic Flow, [[Traffic NO2(Overlay)|Traffic NO2 Pollution]] and [[Traffic Noise (Overlay)|Traffic Noise]]. The general purpose is to simulate traffic impact and not the traffic logistics in an area.
 
== Traffic Models available in the Tygron Engine ==
 
: The Tygron Engine makes, by default, traffic based calculations for results such as the Traffic Flow overlay, the Traffic NO2 overlay and Traffic Sound Pollution. These calculations are based on many different data sets. These data sets are different for each location/ country.
 
=== Data Sources ===
When creating a [[Main Menu#New Project|new project]] based on real data in the Tygron Engine, a standard traffic flow is generated for the project area, based on available (open) data sources. For the Netherlands these sources are:
 
:;NSL Monitoringstool:https://www.nsl-monitoring.nl/
:;PDOK RDW wegen:https://www.pdok.nl/nl/service/wfs-nwb-wegen-nationaal-wegen-bestand
:;INWEVA 2015:https://nis.rijkswaterstaat.nl/portalcontent/logon/p2_33.html

== How to add or edit a (custom) traffic model in the Tygron Engine ==
: Besides using the default traffic calculations, it is also possible to add a custom traffic model. Traffic models can be added directly as a static model, or as 'patches' for a dynamic model.
 
: In order to up-load a custom traffic model, it has to be prepared as a Geojson file, in the correct coordinate system.
