Inter-vehicle and vehicle to roadside communication (V2X communication) allow both passenger safety and driving comfort to be improved significantly. For example, a vehicle detecting an icy road could inform following vehicles and thereby prevent accidents. Vehicle to roadside communication could be used near construction sites to warn the vehicle driver about reduced number of lanes or to give him advice for an alternative route. For improved traffic efficiency, vehicles could exchange the latest traffic flow information. The advantages of V2X communication have been recognized in many regions of the world. Research initiatives worldwide have started and have already produced valuable results. Additional projects to solve the open issues are on the way. Many regional efforts are taken to consolidate the results from research projects in industrial standards. Industry consortia have been formed, namely the Car2Car Communication Consortium in Europe, the Vehicle Safety Communication Consortium in the US and the Advanced Cruise-Assist Highway System Research Association in Japan. Unfortunately, the regional variance of boundary conditions for the development of V2X communication is standing against an easy worldwide harmonization. Still, the mutual awareness of the world wide initiatives is growing. An increasing number of companies try to bridge the gaps between the regional developments.
