PReVAL addresses the possible safety impacts of functions developed and demonstrated in the PReVENT integrated project. One of the major aims of the PReVAL project is the development of a harmonized framework for the assessment of preventive safety applications and advanced driver assistance functions. The work described in this deliverable is a major step towards this objective. In deliverable D16.1 [1] the evaluation methodologies used by the PReVENT subprojects and related projects, such as eIMPACT, APROSYS, AIDE and CONVERGE were reviewed. Based on this work, evaluation procedures are proposed for technical performance and human factors, which are described in this deliverable. The safety potential of an application is determined by the technical performance, the reliability of the system, the human factors (the interaction between the driver and the vehicle) and the traffic safety level. For the safety impact analysis, the behavioural effect approach, which has been developed and used by the eIMPACT project, is considered. As a general concept to link the different evaluation procedures, the concept of situational control is introduced. Situational control refers to the level of control jointly achieved by the driver and the vehicle in a specific driving situation. In general, the purpose of preventive safety systems and advanced driver assistance systems could then be understood as the increase of situational control. Consequently, the general goal of the system evaluation is to assess the extent, to which this is achieved. PReVAL proposes to extend the Vshape design cycle, which is common in the automotive industry, with steps focused on evaluation. These steps include the evaluation specifications and the test definition. In most cases, the system or function specifications are not detailed enough to design the evaluation tests. The evaluation specifications contain all the information needed for design of the tests for the different evaluations. A key part of the evaluation specifications is the function description, which is common for the three procedures. (Author/publisher)
