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, i.e. the throughput of mobile units (e.g. vehicles) per time and transportation medium capacity (e.g. 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 Pollution and 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 traffic based calculations for results such as the Traffic Flow overlay, the Traffic NO2 overlay and Traffic Sound Polution. These calculations are based on many different data sets. These data sets are different for each location/ country.

Data Sources

When creating a new project based on real data in the Tygron Engine, a standard traffic flow is created for the project area, based on available (open) data sources. For the Netherlands these sources are:
