Road ahead cleared for European C2X car-data-comms standard

February 14, 2014 // By Christoph Hammerschmidt
Cars that can automatically transmit hazard warnings are one step closer to reality. At a workshop in Berlin, standard bodies ETSI and CEN announced that they have agreed a basic set of standards for Cooperative Intelligent Transport Systems (C-ITS). The agreement ensures that vehicles from different manufacturers will understand each others' radio data messages. The first such vehicles could be commercially available as early as 2015.

The set of standards includes, among other matters, radio frequencies and data formats. The European standard bodies collaborated closely with their counterparts in North America and Japan to ensure global compatibility. With more than 200 million vehicles on Europe's roads today, experts expect a detectable positive effect on travel safety once more than 10% of vehicles are mutually connected.

Work is underway in both standard entities to develop release 2 which will include the communication between vehicles and roadside infrastructure such as traffic signs and traffic lights - that is, car-to-infrastructure as well as car-to-car.

The development of these standards was assigned to ETSI and CEN by the European Commission in 2009. The EC also funded several research projects such as eCoMove, Drive C2X and COMeSafety. The US Department of Transport recently also gave green light to the development of Car2X standards.
