Examination of Light-Based Directed Vehicle to Everything Communications Systems for Bridge Strike Detection

With the emergence of advanced driver assistance systems (ADAS) in most modern passenger vehicles, the need for reliable transmission of data from vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) has become apparent. However, many commercial vehicles such as buses and semi-trucks are technologically behind when it comes to sensing potential safety hazards, while having the potential to cause catastrophic damage due to their increased size and weight. One of the most common safety incidents involving large commercial vehicles are bridge strikes and tunnel strikes, where the driver of a tall-load vehicle attempts to pass under a bridge or tunnel and the top of the load collides with the bottom of the overpass. According to the National Highway Safety Administration, there are approximately 15,000 bridge strikes in the USA annually, with potentially more going unreported. These bridge strikes cause a serious threat to the safety of all road users, as well as a substantial financial cost in the form of infrastructure repair, road closures, and traffic disruption.
