TVP

The aim of the TVP (Traversée des Voies à niveau par le Public) project is to identify, develop and prototype one or more new solutions for reducing dreaded events (RE) at TVP.

By combining behavioral and biomechanical analysis, built around the data produced within the complete experimental platform (reproduction of body movements in open fields, kinematic analysis, attention management, eye search patterns, muscular efforts, interaction with the environment and other travelers), the project therefore has scientific and technical objectives of several kinds:

• Design, around the analysis of the literature and levers already identified, new concepts for safety systems,
• Validate, in the upstream phase, the feasibility and effectiveness of the envisaged system concepts,
• Model and test in ecological situations one or more new-generation safety system concepts, check their integrability in the infrastructure system and in relation to the needs of rail traffic,
• Achieve a demonstrator compatible with the railway domain of the selected concept(s), to be deployed on the private test site at Vaires sur Marne.

This thesis aims to meet the theoretical and experimental needs of the TVP project through the scientific angle of biomechanics.

The main objective of this thesis is then to analyze motor behaviors and patterns mainly of a biomechanical nature (kinematics, dynamics, EMG), during a lane crossing exposure (TVP) in order to characterize and quantify crossings deemed at risk for users. The aim here is to reveal relevant and useful biomarkers for the virtual situation and thus better understand user behavior to reduce its consequences.

The second objective is to compare the different devices set up via mixed reality (platform of a 1:1 scale platform coupled with a virtual reality environment) from a motor control point of view.

The set of biomechanical measurements will thus make it possible to characterize user profiles and thus highlight the role of the various signage devices.
