  RetroI2V

  Conventional road signs convey very concise and static visual information to human drivers, and bear retroreflective coating for better visibility at night. RetroI2V exploits the retroreflective coating of road signs and establishes visible light backscattering communication (VLBC), and further coordinates multiple concurrent VLBC sessions among road signs and approaching vehicles.
