BSAG, the public transit operator in the German city of Bremen is using a system called AI Watch to detect potential security problems inside its trams and will equip a third of its fleet with the software by the end of the year. With 37m trams the interior visibility for drivers is restricted. AI Watch carries out real-time analysis of video images from interior cameras and identifies potential threats. All data remains on the vehicle. The system has been trained using specially staged and realistically created scenarios such as physical altercations and aggressive behaviour. Over four hours of footage were created. The relevant image is transmitted live to the BSAG control centre for assessment and response. The development of the system and trial on one vehicle cost EUR 500 000 with 80% covered by the Federal Ministry of Transport. The success of the trial has led to the decision to expand across the fleet of Siemens Avenio trams.
AI Watch was developed in collaboration with the Bremen-based company Add AI and is so far unique in Germany.
