Requirements and specifications for test execution and management. Appropriate use cases for vehicular communication are selected for the testing that will be done during the planned “limited” impact assessment described below. Based on these use cases the requirements for the testing architecture, for test management and for test site selection will be derived and test metrics and procedures developed.

50 use cases on safety, traffic efficiency, infotainment, business have been collected from relevant projects and activities such as:

• SAFESPOT
• COOPERS
• CVIS
• PReVENT/WILLWARN
• Network on Wheels

Impact assessment and demonstration. The objective is to demonstrate and functionally verify the prototype of the inter-vehicle and vehicle to infrastructure communication system developed on the basis of common European architecture. The aim is to proof, that the system fulfils the needs originated by the use cases and can be used as basis for the large scale field trials. The tests also serve to verify the methodologies developed in PRE-DRIVE C2X and to do a first analysis of the system impact that of inter-vehicle and vehicle to infrastructure communication system in Europe.

A first assessment of the architecture prototype and the evaluation methodologies will be conducted. This helps to identify gaps as well as technical limits. The assessment is accompanied by an application of the simulation tool set to give a first impression of the system benefits. One particular outcome is a reliable cost/benefit estimation. The assessment is combined with a system demonstration in order to promote the common European communication architecture and the planned field trials.

Based on the results of the tests and simulations conducted in PRE-DRIVE C2X the social impact of inter-vehicle and vehicle to infrastructure communication shall be determined by estimating the number of accidents which can be avoided through vehicle safety communication and the improvement of traffic flow, which is expected to result in less traffic jams and less environmental impact.
