Passengers of the streetcar line No. 6 in the small town of Karlsruhe in the southeastern part of Germany know whether a spontaneous purchase at the next stop is worthwhile: Screens in the car display special offers of shops close by. The application of this location-based service was developed by Yellowmap, a German company specializing in processing geographical information. However, the application is neither GPS-based, nor does it use mobile-phone technology, nor has it any connection to the Internet. It’s based on the conventional sensor system in the track of the streetcar.
Nevertheless, this is interesting new technology and a new service to the town’s inhabitants. The pilot project was funded by the European Commission within its ELBA (European Location Based Advertising) program. It will be continued by the public transportation company Karlsruher Verkehrsverbund (KVV). Apart from commercial offers, information on various local facilities can be displayed.
