Below you find several examples of what can be done with MATSim, and how results can be visualized.
Visualization in GoogleEarth
See cars driving around in the center of Berlin, Germany, during the morning hours. The vehicles' positions are updated for every minute. Requires Google Earth 4.2 or newer to see the animation.
Visualization of the complete day plan of two agents. One agent is living near the location marked with "h12" and currently traveling on the left side of lake of Zurich northwards. It will work at "w10" and do some leisure afterwards at "l2", before returning home again (over the Forch-region). Another agent lives at "h16" and is currently executing some leisure activity at "l1" (marked red), and will later work at the place "w7", before driving home again. The screenshot is from the MATSim On-The-Fly-Visualizer (OTFVis), an integral part of MATSim.
See the individual cars simulated, first in an overview of whole Switzerland, and then zoom in onto a single crossing in Zurich. (Screenshots in a multi-page PDF document. Scrolling fast through the pages, you get a simple animation)
Look at the individual cars driving around in the area of Zurich, Switzerland, over a timespan of 40 minutes. (Screenshots in a multi-page PDF document. Scrolling fast through the pages, you get a simple animation)
Look at the individual cars driving around in the area of Zurich, Switzerland, over a complete simulated day. For performance reasons, only 10pct of the cars are shown.
Comparison with Counting Stations
For the analysis and verification of simulations you can compare the values from the simulation to real values of counting stations. The file below shows you an example of such a comparison in the region of Zurich, Switzerland, that can automatically be generated by MATSim. Requires Google Earth 4.2 or newer to see the animation.
Visualization of MATSim Output with External Tools
MATSim output has a simple structure so it can easily be transformed and used by other applications. The example below shows the paths of all travellers crossing the "Baregg tunnel" heading towards Zurich, Switzerland, between 7am and 8am ("Dynamic Spider-Analysis" / "Dynamische Spinnen-Analyse"). The colors show where the agents were earlier (on the left side of the tunnel) or later (on the right side) in 30min steps. The analysis and picture was generated with a Geographical Information System (GIS).
MATSim is also used to simulate large-scale evacuation simulations. See the Padang Scenario for more details.
Nagel-Schreckenberg-Model: Traffic jam out of nowhere
The movie illustrates the "traffic jam out of nowhere" feature of the Nagel-Schreckenberg model. Cars move from bottom left to top right. At simulation time 2:27 (movie time 0:00:11), a traffic jam emerges near the top right corner, and slowly moves to the bottom left while growing longer. Please note that MATSim uses a slightly different model internally nowadays which does no longer allow to visualize traffic jams out of nowhere the same way as demonstrated here.
