Abstract:
A four-legged traffic lights controlled crossroad with Vehicular Visible Light Communication (V-VLC) is used for trajectory management, using request/response concept and relative pose estimation. The connected vehicles receive information from the network and interact with each other and with the infrastructure. An Intersection Manager (IM) coordinates traffic crossings and interacts with vehicles through temporal/space relative pose concepts. V-VLC is performed using the street lamps, the traffic signaling and the headlamps to broadcast the information. Data is encoded, modulated and converted into light signals emitted by the transmitters. As receivers and decoders, optical sensors with light filtering properties are used. Cooperative localization is realized in a distributed way with the incorporation of the indirect vehicle-to-vehicle relative pose estimation method. A phasing traffic flow is developed, as Proof of Concept (PoC) and a generic model of cooperative transmission is analysed. The results express that the vehicle’s behavior (successive poses) is mainly influenced by the maneuver permission and presence of other vehicles.
