To support and prepare the introduction of Cyclist-AEB systems and the appropriate consumer tests of such systems, TNO set up a project with passenger car manufacturers and suppliers with the support of research and development partners (such as BASt and 4activeSystems) to develop a testing system and test protocol for CATS, Cyclist-AEB Testing System. This report describes the setup of the project and the approach that was followed from the start in June 2014 to the conclusion in June 2016. Moreover, the report summarises the most important results out of the project.
