 * The coupling to [OMNeT++](https://omnetpp.org) is implemented in a very similar manner. The corresponding federate implementation can be found [in our MOSAIC Addons repository](https://github.com/mosaic-addons/omnetpp-federate). 
   We currently support OMNeT++ version `5.5` in combination with the INET framework in version `4.1`.  
 * We created the [Berlin SUMO Traffic (BeST) scenario](https://github.com/mosaic-addons/best-scenario) which provides 2.2 million vehicle trips in 24h for Berlin, Germany. The scenario is fully compatible with the latest release of MOSAIC.
+* In our research, we currently use Eclipse MOSAIC and the BeST scenario to evaluate traffic state estimation algorithms. For that, we provide [application models and tools for Traffic State Estimation](https://github.com/mosaic-addons/traffic-state-estimation) compatible with MOSAIC.
