Connected and automated driving (CAD) of road transport will lead to partial or complete replacement of the vehicle driver by automation. CAD has the potential to change multiple dimensions of the transportation system, ranging from changes in car ownership to the availability of new mobility services to improvements in road safety and traffic flow. Adoption of CAD requires coordination of numerous, heterogeneous innovation actors in different domains. To do this successfully requires planned actions whose interactions lead to intended and unintended consequences. Technical and economic approaches must be considered, as well as the impact on individuals and society.
The widespread adoption of CAD, and thus its impacts and consequences, depend on a number of factors, including adoption rates and diffusion rates of CAD vehicles and CAD mobility services, as well as changes in individual mobility behavior and thus collective travel demand resulting from the availability of and use of the new transportation alternatives.
CADIA focuses on two research tasks:
The CADIA project is part of a German-Japanese research collaboration. The analyses are of particular relevance due to the economic importance of the automotive industry in both countries. Therefore, in the course of the project, the exchange on the project content and progress as well as the results of the Japanese partner project will be pursued.
The objectives of the project are:
-Investigating the significance of the concept of "social acceptance" of automated driving in this context, linking German (and European) perspectives and scientific thinking with the Japanese perspective, and expanding the respective perspectives to include elements of comparative research.
-Developing a deeper understanding of the impact of external factors on the diffusion and influence of CAD technology on vehicle fleet development and transportation demand by comparing Japan and Germany internationally as prototypical mobility markets
-Development of future-proof modeling tools to support decision-making to plan the market introduction of CAD technology beyond vehicle-related technical issues
-Develop future market diffusion scenarios of CAD technology in the passenger car fleet to provide associated impacts on vehicle sales.
In addition, one goal of the project is to exchange and network with Japanese partners within the research collaboration.
The main focus of the work of the DLR Institute of Transport Research in this project is the further development of existing modeling tools for passenger car ownership and transport demand. The latest findings on market entry scenarios, social acceptance and the car ownership behavior of households will be incorporated. The model tools are applied to automation scenarios to be defined and a holistic evaluation of the results is performed.
The further development of the models refers to the following modeling tools:
Within the framework of the research cooperation with the Japanese partners, joint project meetings are held to exchange information on issues, procedures and results of the two projects.
The project is funded by the German Federal Ministry of Education and Research (BMBF)
