According to United States Department of Transport (USDOT) statistics, roadway accidents are the leading cause of death for the age group 4–34years with over 30,000 deaths a year. These roadway accidents also have a direct economic cost of over $200 billion. Day-to-day roadway traffic congestion is estimated to drain around 4.2 billion lost hours per year and the associated financial loss is estimated to be over $87 billion.The use of wireless technology to enable communications between all road user entities (generally termed V2X or Vehicle‐to‐Entity) so that they are aware of each other is seen as a promising approach to lessen the negative implications of road accidents and traffic congestion. USDOT IntelliDrive program is the official initiative to do exactly that.
