Examination of Light-Based Directed Vehicle to Everything Communications Systems for Bridge Strike Detection (Using ImpLi-Fi)
In this proposed project, the ImpLi-Fi team - consisting of the University of Michigan-Dearborn and SpectraLux, LLC - will deploy a reliable and directed light-based wireless infrastructure-to-vehicle communication technology to warn at-risk trucks of imminent bridge strikes. Once shown to be feasible, the same concept can also be extended to flash flood warning, wrong-way driving, etc. Unlike wireless communications using radio-frequency (RF), which are always omni-directional, ImpLi-Fi uses light, allowing transmissions to be focused so that they only target specific impacted vehicles, thereby avoiding the risk of annoying/desensitizing other parallel road users.
