C2X communication is expected to provide what is called the Telematics Horizon. It will enable drivers to look further ahead than they would relying on their eyes and in vehicle sensors only. Through C2X communication drivers will be informed about potentially dangerous situations in front of them in due time before they reach this particular spot. Driving simulator studies have shown that drivers having received warnings via C2X communication will adapt their speed better to the potentially safety critical situations than drivers that have not received a warning. It is obvious that this will have a direct effect on number and severity of accidents resulting in the reduction of accident costs foremost but also in the reduction of congestion costs, time costs, emission costs and costs for vehicle operation. Details on the cost savings that can be expected here can be found in PRE-DRIVE C2X Deliverable D5.2-5.3 Social, political economics and business economics impacts of cooperative systems, potential business models, please contact us for acquiring the documents.
In DRIVE C2X a number of safety related functions are tested and evaluated on several test sites in Europe. These functions are described in the Driving section of this website. The evaluation results will be published as soon as they become available.
