Scaling up of ADAS’ Traffic Impacts to German Cities

The paper presents a methodology developed in the context of the German research project UR:BAN-VV in order to transfer and extrapolate the impacts of cooperative advanced driver assistance systems to German cities. To limit the simulation scenarios of the impact assessment and to focus on most relevant urban structures in Germany, real data of all 187 German cities larger than 50,000 inhabitants are considered for an analysis at two different levels of detail. Firstly, a questionnaire-based survey of all cities provides a solid overview of macroscopic structure of traffic management and control strategies in these cities. Secondly, a statistically supported approach that will help to identify most typical structures and attributes on a more detailed level (i.e. signalised intersections and road segments) is described. In this way, typical network elements and structures for German cities are identified. Microscopic traffic simulation will provide dedicated information on the effects of cooperative advanced driver assistance systems on traffic efficiency, sustainability and safety for these elements. The results are transferable to other cities. The paper presents the status of the first three steps of the methodology.     «
