Sexual assault and sexual harassment still pres- ent problems for people using Paris’ public transit systems. Women in particular regularly experience threats to their safety and dignity. Previous ap- proaches have increased security measures, raised awareness, and created self-reporting methods for incidents, but we need to provide bystanders, or wit- nesses, with the tools and education to help their fellow passengers and create a safer transit system. BonVoyage seeks to address this in two ways: build- ing a mobile app that uses Bluetooth technology in public transportation to connect people with a net- work of nearby active bystanders and creating a set of interactive training modules.


Inspired by adaptive neuroplasticity, these modules will provide an interactive, decision-based experience to make bystander intervention a more natural response.

BonVoyage wants to make our base-level products accessible to everyone free of charge, but we also plan to offer premium customized training sessions to corporate and public partners.


We especially want to collaborate with women’s empowerment organizations to incorporate our active bystander network into their existing efforts. Ultimately, BonVoyage wants to shift the responsibility of staying safe away from victims, and, through a network of active by- standers, give the movement against sexual assault and harassment a collective voice.
