Using an integrated simulation environment for the risk based design of advanced driver assistance systems

When designing new Advanced Driver Assistance Systems (ADAS), the existing guidelines like the RESPONSE 3 Code of Practice imply intense testing of the system prior series production. Within the EU-FP7-Project ISi-PADAS a new methodology of risk based design has been established which includes an integrated simulation platform. This integration enables intense testing of new prototypes in an accelerated way and therefore enhances the design process while directly combining the simulation results with a risk matrix.This paper describes the new methodology while focussing on the software framework and the procedure of risk assessment in detail. It shows the general approach as well as the appropriate steps taken for an ADAS prototype developed in the context of ISi-PADAS.     

Localizing Detroit’s Food System: Boundary-Work and the Politics of Experiential Expertise

ABSTRACT

Recently, different expert actors have attempted to localize Detroit’s food system to bring about greater justice citywide. At first, ‘professional experts’ dominated these efforts, claiming authority in the food system due to their knowledge based in qualified training and applied work experience. Yet a rival group of ‘experiential experts’ soon rose up to assert their power, arguing they and their unique race and place-based know-how merited greater influence. Within just a few years, experiential experts successfully replaced professional ones in commanding much area food localization. I show that experiential experts achieved this power largely through strategic boundary-work, including expulsion, expansion, and protection of autonomy. Nonetheless, some Detroiters and professional experts themselves questioned experiential experts’ legitimacy in removing professional experts from the food system altogether. I thus introduce a fourth form of boundary-work that experiential experts deployed to maintain their clout, what I term ‘accommodation’. Accommodation connotes instances of strategic inclusion where an expert authority facilitates rivals in sharing some influence based on distinct conditions that leave dominant epistemic arrangements generally intact. This occurred in Detroit as experiential experts accommodated professional ones in exercising some food systems power provided they better deploy their own race and place-based knowledge. Such actions helped quell public concern while also protecting experiential experts’ rising authority. Accommodation is useful for understanding cases in which diverse types of experts work together despite that single knowledge-forms guide their activities overall. Further research into accommodation could aid in identifying whether or not diverse forms of knowledge are together influencing decision-making around a range of cases, or if single forms of expertise remain dominant despite the appearance that democratization is taking place.
