Car2X – Upgrade of Emergency Telephones for V2I Communication on Highways



Communication vehicle-to-vehicle and vehicle-to-infrastructure is one of the groundbreaking trends of tomorrow’s mobility.

The first serial-production cars with such equipment are expected to arrive on German streets in the next years.

The ANIKA project checked the technical feasibility for upgrading the emergency phones along the German Autobahn system so that they can be enabled for data communication with passing cars (V2I communication). The emergency phones could support V2I applications like warning about traffic jams or broken-down vehicles.

The intelligent upgrade of the emergency phones is a meaningful and resource-efficient future use of existing traffic infrastructure. Emergency phones are connected to a central control room already that answers, processes and coordinates the calls.

The ANIKA project also tested whether the car data received by the emergency phones could be used for traffic management. Traffic control centers could communicate instructions for intelligent traffic management directly to the passing cars.

The ANIKA project was carried out as two cooperating sister projects in Lower Saxony and Saxony-Anhalt. The projects were funded by the ministry of economics, labor and transport in Lower Saxony and in Saxony-Anhalt by the ministry of science and economics, the ministry of regional development and transport as well as Investitionsbank Sachsen-Anhalt.
