Are Connected and Automated Vehicles the Silver Bullet for Future Transportation Challenges? Benefits and Weaknesses on Safety, Consumption, and Traffic Congestion
Résumé
With the growing development of Cooperative, Connected, and Automated Mobility
(CCAM), questions arise about the real impact of this innovative mobility on our daily
life. CCAM originally promised to improve road safety. It is now a holistic solution for
future mobility: the CCAM is there to optimize traffic, which can translate into strategies
for reducing energy consumption or polluting emissions, without compromising road
safety. The capability of CCAM is dependent on the reliability and robustness of its
components, as it will be making life-impacting decisions. It is therefore necessary to
be able to guarantee a high-level quality of sensors, communication, software, and
hardware architecture. In this mobility ecosystem, the infrastructure and data that it will
be able to produce is at the heart of current research issues. This paper addresses
the following question: Are the Connected and automated Vehicles (CAVs) the silver
bullet solution with which to answer the issues of the current mobility systems? This
question is discussed by investigating the technologies used, the digital infrastructures,
its robustness to cyber-attack, and their relationship with the claimed benefits on safety,
energy and pollution management, traffic optimization, deployment strategy, and a link
with the new generation of road infrastructures
