Système coopératif de perception et de communication pour la protection des usagers vulnérables

Abstract : Cooperative intelligent transportation systems (C-ITS) have the opportunity to enhance road safety, especially the safety of vulnerable road users (VRU), e.g., pedestrians and cyclists. Road accidents are mainly due to vehicles' and VRUs' inability to detect the danger before a collision cannot be avoided.We introduce a perception system based on laser and camera sensors to estimate the state of VRUs located around the vehicle. A multi-class classification of road obstacles based on laser data has been developed using statistical machine learning and Bayesian estimation.We propose an architecture for vehicles-to-pedestrians (V2P) communication which considers the weak energy resources of the devices carried by pedestrians such as smartphones. Our solution is relying on the standards defined by ETSI ITS architecture for vehicular communication and proposes geographical dissemination for V2P communication.A cooperative perception/communication system can deal with scenarios which are becoming more and more complex by combining the ability of perception to estimate the dynamic state of detected obstacles and the ability of communication to exchange a rich content between distant users. We introduce a multi-hypotheses fusion between perception and communication information and a smartphone application dedicated to protect VRUs from road danger.The solutions proposed during this thesis are evaluated on real data. We carried out real experiments on INRIA campus demonstrating the assets of a cooperative system for the protection of vulnerable road users.
