BLE-based Relative Positioning in the Context of Targeted Bike-to-Vehicle (B2V) Communication

Communication between cyclists and drivers is often difficult in an urban environment. E-bell is an existing project that addresses the problem of communicating in these environments. This paper builds on this existing project by developing a way to do relative positioning of vehicles around a bike using Bluetooth Low Energy, enabling targeted communication between vehicles. It shows that it is possible to only use Bluetooth Low Energy to step away from broadcasting and send targeted messages to a group of specific vehicles.
