A Distributed and Privacy-Aware Speed Advisory System for Minimisation of Emissions in an ITS Scenario

One of the key ideas to make Intelligent Transportation Systems (ITS) work effectively is to deploy advanced communication and cooperative control technologies among the vehicles and road infrastructures. In this spirit, we propose a consensus based distributed speed advisory system that optimally determines a recommended common speed for a given highway in order that the group emissions are minimised. Our algorithms achieve this in a privacy-aware manual; namely, individual vehicles do not reveal in-vehicle information to other vehicles or to infrastructure. Mathematical proofs are given to prove the convergence of the algorithm, SUMO simulations are given to illustrate the efficacy of the algorithm, and hardware-in-theloop tests involving real vehicles are given to illustrate user acceptability and ease of the deployment.
