National projets


Autonomous shuttle experiment

2019- 2022

The ENA (Autonomous Shuttle Experiment) project managed by Gustave Eiffel (ex IFSTTAR) aims to perform experiments based on autonomous vehicles, marketable by 2022, as a complement to existing public transport networks. It is part of the ADEME EVRA call for projects (Experimentation for Autonomous Road Vehicle). ENA project brings together two territories on which experiments will be launched: in the Brenne (opening up in rural areas) and Sophia-Antipolis (serving a business park). The project will identify needs to implement autonomous shuttles, then it will perform experiments to collect and to share the feedback and the impacts to improve this type of mobility.

Within the ENA project, the AME/EASE laboratory is involved in two parts: "Quality of service: safety and comfort", whose objective is to develop physical indicators to assess the level of safety and comfort of the shuttles in normal conditions and in critical situations; and "Evaluation on tracks", whose objective is to identify the tests needed to assess the risks linked to the shuttle routes, as well as the safety and comfort of users through experiments on tracks. The AME/EASE laboratory is carrying out experiments on the Reference Tracker tracks and Experimentation (PRER), in Nantes, to evaluate the braking distances of the NAVYA Shuttle under different environmental conditions, in order to estimate the safety of the shuttles that will be deployed on the territories.

Modelization/characterization of precursor and secondary aerosol from road traffic – Euro6 vehicles

2018- 2022

Maestro-EU6 is the continuation of the Maestro project. It pursues the objective to enrich knowledge on the emission factors of regulated and non-regulated compounds and on the evolution of pollutants through atmospheric physico-chemical and photochemical processes, but focuses on Euro 6 passenger cars with different post-treatment technologies.



The I-Street project managed by Eiffage and involving olikrom, Total and Ifsttar is part of a systemic approach: six technological bricks will be developed, covering all the axes of the ADEME “Road to the Future” call for projects, from the development of a greener, smart and connected road to prefabricated / demountable roads and innovative and safer road marking. EASE laboratory is involved in 4 modules: Globe, Sushis, CUD, Coated for the Future

* Globe, which aims to create a logistics sector for bitumen granules, from the production refinery to the site of use;

* Enrobé du futur which aims to develop an optimazed pavement surface regarding skid resistance, noise, rooling resistance and pollution control;

* CUD which consists in developing a modular urban road, made up of precast concrete elements that are easy to handle;

* SUSHIS which includes the development of photoluminescent horizontal signs, which will enhance user safety in degraded weather conditions and allow energy savings on urban sites.


New POLlutant EMIssions from modern Euro 6 CarS: atmospheric transformations and implications for urban air quality and health

2018- 2021

Polemics project proposes to investigate nature, fate and impacts of Euro 6 emissions, both in the laboratory and in the real world. Car exhaust will be measured at the tailpipe and after processing in static and dynamic atmosphere simulation reactors. Primary emissions and oxidation products will be analyzed. Their contribution to secondary particle formation will be investigated. The obtained kinetic and product information will be used for enhanced air quality modelling, both on the process and on the urban scale. The genotoxic potential of primary and secondary particles will be assessed using standard in vitro assays. 


Determination of Semi-Volatile Organic compounds emissions by volatility classes. Impact on air quality modelling

2017- 2020

Modelization/characterization of precursor and secondary aerosol from road traffic


The MAESTRO project aims to improve knowledge on emissions of VOCs, SVOCs and particles from passenger cars. This project aims also to investigate the particle ageing and secondary particles formation under atmospheric conditions. These experimental results allow developing the ageing parameters for air quality models.

Effect of (over) loads on the braking distance of LCVs

2019- 2020

The DSR wishes to assess more precisely the risk linked to overloading of light commercial vehicles (LCVs) in terms of braking distance in particular. This project involving Cerema (Lyon Laboratory Department) and IFSTTAR (EASE laboratory) aims to assess the variations in braking distances induced by overloads under different conditions: dry or wet road, speeds varying from 50 to 120 km / h, load distribution and overload rate. To reach this goal, two additional steps are proposed. The first is based on the modeling of a LCV and numerical simulations (with PROSPER vehicle dynamics software). The second consists in the instrumentation of a light commercial vehicle and the carrying out of tests on the reference test track at university in Nantes. These tests will validate the results obtained by numerical simulations.

ITTECOP programme


The Gedev project considers the operational and legal feasibility of green verges’ (GV) management by competent local actors involved in the management of (sem natural environments. For land transport infrastructure (LTIs) managers, using the skills of local stakeholders in natural environment management may be a solution to meet their need to implement biodiversity-friendly practices in GVs (conservation, connectivity). However, such initiatives remain limited and the possibilities for replication in other contexts are unclear.
