The PICS-L (Lab on Perceptions, Interactions, Behaviours & Simulations of road and street users) conducts pluridisciplinary research to develop knowledge and tools in order to observe, understand, improve and evaluate the mobility of individual road and street users with various levels of assistance and automation.

The lab has about forty members. It is present on 4 campuses of the University Gustave Eiffel: Marne la Vallée, Versailles, Nantes and Lyon.

The focus of research at the PICS-L is the behaviour of single users of the road and urban transport system (mainly light vehicles with advanced driving assistance or automation, cyclists and pedestrians) as they interact with other users and with the infrastructure. The lab conducts applied research in 4 cross-disciplinary areas in order to foster interdisciplinarity and innovation:

• perceptions and planning, to understand and model perception systems and the main phenomena which disrupt their operation;
• behaviours and interactions, to analyse and model the behaviours of users and their vehicles as they interact with the infrastructure and with other users;
• immersive simulation, to validate the simulators implemented to study the interactions of human or machine driven locomotion with the travel environment;
• road and street user assistance systems, to design and/or evaluate innovative solutions to improve user safety and experience.

The lab develops and implements 4 types of scientific equipment which are both research tools and research objects:

• immersive simulators (for drivers, cyclists, pedestians);
• instrumented vehicles (automated and connected);
• photometric and psychometric measurement systems;
• camera-based travel observatories.

The PICS-L was created in 2020 by the merging of 2 laboratories of the COSYS department:

• the Laboratory on Vehicle-Infrastructure-Driver Interactions (LIVIC, created in 1999);
• The Laboratory on road Operation, Perception, Simulators and Simulations (LEPSiS, created in 2009).
