MoSAIC
Laboratory for multi-user simulation
The Modular and Scalable Application Platform for ITS components (MoSAIC) offers a laboratory infrastructure that enables multi-user simulation for designing, developing, and evaluating cooperative and conventional driver assistance systems, as well as for investigating cooperation and interaction between road users.
What special features does the MoSAIC multi-user simulation offer?
MoSAIC is a modular, scalable architecture for multi-user simulation. Using this platform, the existing simulators of the DLR Institute of Transportation Systems can be coupled and operated from one control centre. The MoSAIC concept is used for the design, development and evaluation of how traffic participants communicate and interact.
The MoSAIC-VRU-Lab is a laboratory infrastructure specifically designed for multi-user scenarios, in which cooperative assistance functions can be tested in realistic environments, such as the Lower Saxony test field or AIM, prior to their validation. This is particularly important as the individual behaviour of different road users and their interactions continue to play increasingly significant roles in the development of new mobility solutions. Up to two static driving simulators, two pedestrian simulators and a bicycle simulator are available in the MoSAIC-VRU-Lab to assist research on these topics and help answer scientific questions.
