Increase of travel safety for public transport by mobile applications

Mitigating vandalism in local traffic and at stations, violent disorder, and theft by employing security guards, installing video cameras are expensive and only partially solve existing the problems. Related costs directly affect the fares and thus the attractiveness of local public transport. We discuss a concept to implement a Report-service to forward emergency and complaint messages in local public transport. The service is based on a mobile application and a message routing system. The aim is to increase travel safety and the attractiveness of the local public transport. On the base of theoretical approaches and the usage of paper prototypes we show the possibilities how such a Report-service could be implemented.
