With the growing importance of cooperative intelligent transport systems (C-ITS), 3GPP has standardized LTE-V2X (Long Term Evolution - Vehicle-to-everything) in Release 14 to address specifically vehicle-to-everything (V2X) connectivity. This standard introduces a mode 4, in which vehicles allocate radio resources autonomously without cellular infr...
A new paradigm based on the concept of virtual coupling of train sets is being elaborated to provide innovative solutions so as to increase efficiency, operational flexibility, line capacity, competitiveness among market players and quality of consumer experience. Train-to-Train (T2T) and Train-to-Ground (T2G) wireless communications will be the ba...
A key question about cooperative vehicle longitudinal control is reactivity, which determines the future of road safety, and capacity. In adaptive cruise control (ACC), the controller adapts the speed of the vehicle to its immediate leader's speed whereas, in the cooperative version (CACC), connectivity between the platoon equipped vehicles reduces...
The last decade has witnessed the evolution and advanced of new technologies for Intelligent Transportation Systems (ITS). In particular, Cooperative ITS (C-ITS) covers a large and wide range of new technologies that are deployed as part of Information Technologies (IT) systems aiming to improve road safety, driver comfort, transport efficiency and...
Lane change maneuvers are main causes of traffic turbulence at highway bottlenecks. We propose a dynamic game framework to derive the system optimum strategy for a network of cooperative vehicles interacting at a merging bottleneck. Cooperative vehicles on the highway mainline seek for optimal strategies (i.e. whether and when to perform courtesy l...
Routing protocols for vehicular ad hoc networks resort to clustering in order to optimize network performance. Concerning the Optimized Link State Routing (OLSR) protocol and the plethora of its derivatives, the multipoint relaying (MPR) technique has proven its efficiency as an accurate clustering scheme over the last two decades. However, it has ...

BackgroundSurging acceptance of adaptive cruise control (ACC) across the globe is further escalating concerns over its energy impact. Two questions have directed much of this project: how to distinguish ACC driving behaviour from that of the human driver and how to identify the ACC energy impact. As opposed to simulations or test-track experiments ...
Vehicle Ad-hoc Networks (VANETs) is an emerging research area that has received much attention over the recent years. One of the main challenges of VANET is the routing protocol and the development of reliable ad-hoc communications between vehicles. We proposed a cooperative scheme between V2I and V2V communications in the highway scenarios to exte...
This work presents a microsimulation study on the topic on an uphill network, regarding the potential impact of AVs and Cooperative-AVs (Coop-AVs or CAVs), vehicles able to cooperate with the infrastructure. The novelty of the proposed approach is that the simulation of all vehicles is performed with a common hybrid car-following model that takes e...
Au cours de mon apprentissage au sein du LÉOST, j'ai été impliqué dans des projets axés sur la thématique des véhicules autonomes et connectés grâce à un plan de progression établi avec mes responsables. Ce plan de progression en entreprise est réparti sur trois étapes qui sont la prise en main des instruments de mesures, la mise en situation profe...
