Public transport is a space of insecurity and fear for many people.

While objective crime rates and accidents in European public transport are very low, the subjective feeling of security is very different. Many people (especially women and the elderly) are afraid to use public transport for fear of becoming a victim of aggression. This prevents a widespread adoption of the use of public transport for entire strata of society.

This is an important obstacle to the transition from personal cars to an interconnected mode of service-oriented mobility in the smart cities of the future.

A big problem of safety and risk in public transport is the feeling of being alone – or completely or among strangers who are not interested and are not available to help. This feeling is corroborated by the fact that people in our extensive international cities have less personal contact with their co-citizens and often avoid seeking direct communication with strangers. Because talking to others and asking for help is the primary recommendation of the security authorities on how to behave in such situations, this is a real problem. At the same time, people are more comfortable in managing online communication via their smartphone.


From this need, the project is born. In “DoNotFear” an application will be developed that will allow public transport users to:

  • report fear in situations and places,
  • reporting on other passengers in difficult or needful situations,
  • become members of the community of supportive users,
  • find out, if there are others in the car etc. that intervene in a critical situation,
  • sound an alarm.

This will activate a different channel to bring out solidarity and social behavior without having to interact personally with people before knowing if they will help.

At the end of January 2019 in Berlin there was the official kick-off of the project.

Financed by EiT Digital, the cluster sees as the project leader TU Berlin (Technische Universität Berlin), Technical University of Berlin, Besides :

The Nexus Institute for Cooperation Management and Interdisciplinary Research GmbH was founded in 1999 by the Center for Technology and Society of the Technical University of Berlin.

Nexus has many years of experience in the areas of mobility, space and demography / civil society, globalization and identity / governance, knowledge and organizational culture.

The focus of research and implementation-oriented spatial development projects is the interaction between social processes (eg demographic change, migration), planning (eg urban development, climate adaptation) and infrastructure (eg mobility or energy).
