Carmakers test C2X under winter conditions in Finland

December 18, 2013 // By Christoph Hammerschmidt
If safety-critical technologies such as car-to-x communications eventually will be used in series vehicles and everyday transport, they have to be reliable and must not fail if weather conditions are less than excellent - and the messaging system itself must be pragmatic and useful. For this reason, several carmakers jointly test C2X under winter conditions in Finland.

The DRIVE C2X project, currently conducted in the city of Tampere, includes large-scale testing of automated data communications among vehicles and between roadside infrastructure systems and vehicles under slippery and demanding weather conditions. Participants are carmakers Volvo, Mercedes-Benz and Opel as well as the VTT Technical Research Centre of Finland. VTT is responsible for the test site and participates in project steering, data management and impact analysis.

First-stage field trials were completed at the Tampere test site past May. The current second stage tests a system whereby the drivers receive information on slippery road surfaces and traffic signs over a 22 kilometre stretch of road. Measuring points along the road transmit warnings of slippery stretches and traffic signs such as right of way or speed limits. These warning messages are displayed at the vehicle's dashboard about 400 to 500 metres in advance. 30 drivers generate enough data material to gain statistical relevance. While the data will be analysed only in spring 2014, preliminary results seem to indicate that the tested systems have a positive effect on overall road safety, explained VTT scientist Harri Koskinen.
