Abstract(s)
In order to serve the changing needs of road traffic control, the road space and road structure surrounding an intersection have evolved into complex forms. The redesign or split of the trajectories though complex, can be accomplished by the application of methods for navigation, guidance and combination of expert knowledge of road traffic control of vehicles. A proposed innovative treatment for congested urban is the split intersection. It facilitates a smoother flow with less driver delay by reducing the number of vehicle signal phases. The success of converting to the split intersection is analyzed by using microsimulation. A phasing traffic flow is developed as a proof of concept. A Vehicle-to-Everything (V2X) traffic scenario is stablished and the experimental results confirm the cooperative Visible Light Communication (VLC) architecture showing that communication between connected bicycles and motor vehicles is optimized using a request/response concept. In this work, the communication between the infrastructures and the bicycles and motor vehicles, between vehicles and from the bicycles and motor vehicles to the infrastructures is performed through Visible Light Communication (VLC) using the street lamps and the traffic signaling to broadcast the information. Data is encoded, modulated and converted into light signals emitted by the transmitters. Tetra-chromatic white sources are used providing a different data channel for each chip. As receivers and decoders, SiC Wavelength Division Multiplexer (WDM) optical sensor, with light filtering properties, are used. The primary objective is to control the arrival of vehicles to an intersection and to schedule them to cross it at times that minimizes delays. A Vehicle-to-Everything (V2X) traffic scenario is stablished and bidirectional communication between the infrastructure and the vehicles is tested, using the VLC request/response concept.
