The Darmstadt-based transport company HEAG mobilo operates as an infrastructure provider of the most advanced traffic management systems in Germany. 

With real-time data and service instructions it provides comprehensive passenger information. Together with Luminator realized the HEAG mobilo at their tram stops for the first time a new type of advanced display system in the form of a stele. The cubic vandal stainless steel case houses two bistable displays. It informs public transport customers over the next departures in real-time data quality as well as recent changes in the route network.
