ABSTRACT
This chapter presents research on the acceptability and acceptance of Advanced Rider Assistance Systems (ARAS). It identifies and discusses the Factors that influence riders' acceptance. This chapter addresses only active assistance systems for riders, such as a Curve Warning (CW) system or Intelligent Speed Assistance. ARAS assists the riders in specific situations that may represent a threat and lead to a crash in the absence of an appropriate adjustment of riding behaviour. Riders' acceptance of an ARAS contributes to the safety potential of the system, since it only takes effect if riders acquire the system, install it on their vehicle and activate it during their rides. Regarding acceptance as positive behavioural adaptation in response to the ARAS, the clearest results were achieved by the CW system. ARAS should not take over the control from the riders, but assist them in correctly adapting their behaviour to riding situations where they deviate from safe reference manoeuvres.
