This project is a larger effort to enable Vision Zero Day 3 objectives: intention sharing between road users. The project can be divided in different items that are projects of their own:

PART I: Design and implementation of an embedded system which analyzes the dynamics of an e-bike or scooter (i.e., speed, heading, past trajectory), and can share their desired path for a short time window.

- Using a mobility model based on ODEs, as well as sensors (e.g., GPS, gyroscope, accelerometer), the “ego” e-bike determines its most likely trajectory and lets other users know its desired path for the next steps (e.g., the next 1--2 seconds).

- The expected results of this project are 1) an embedded system that shows the trajectory “reservation” for the bike/scooter visually (e.g., on a computer), and 2) the draft of an extension for the ETSI VAM protocol that shares the "reservation" through a message (e.g., that is then read by a Road-side Unit).

PART II: Design of an intention sharing protocol where VRUs and vehicles are connected and share their desired trajectories for longer time windows.

- Following the same process as part 1, we share our intended trajectory for a longer period and listen to the intentions from other road users. Then, we act upon that information (e.g., slow down if we detect a risk for collision, form a cluster if intentions are similar)

- The result is an extension to the ETSI VAM protocol for clustering, and a proposal for an intention sharing service where VRUs and vehicles interact.
