Our Vision
Digital Twin Road
The mobility of people and goods is a central basis of our modern society with increasingly global and diverse networked processes. In its present form, mobility, especially with regard to road traffic, is currently confronted with global challenges (durability, safety, efficiency, ecology, costs, automation etc.) that urgently require fundamental solutions.
Project Areas
A
Project Area A
In PA A, forward-looking approaches to physical model development (partial models), to the development of functionalized materials, and to the characterization and evaluation of the real object at the material and structural level (experiments, data acquisition, data transfer) are pursued.
B
Project Area B
In PA B, a modular concept for information processing, modeling and use is developed. Data from the vehicle, tires, environment and roadway are to be taken into account. One focus in PA B is the collection and fusion of geometric data and traffic data to describe the current state of the road.
C
Project Area C
In PA C, important connecting questions of fundamental research, which are superordinate to PAs A and B, will be examined successively over the duration of the SFB/TRR 339 and further levels of investigation will be opened up. The first research focus in PA C is the examination of the social aspects of the digital twin road.
