Factors for User Acceptance of Cooperative Assistance Systems: A Two-Step Study Assessing Cooperative Driving

Improved sensor technologies and driver assistance systems offer the possibility for drivers to coordinate their driving maneuvers. Building on this development, a cooperative assistance system could make traffic safer and more efficient. This paper describes the methodology and results of a two-step study evaluating user acceptance factors of a future cooperative assistance system, focusing on passenger cars and heavy trucks. In order to achieve this, cooperative behavior during current traffic situations is evaluated. The analysis shows that one problem in today’s cooperative traffic is to initially recognize the need for cooperation. Cooperative assistance systems that indicate a present possibility of cooperation could support cooperative behavior in traffic. In addition, evaluation of car versus truck drivers in this study shows a difference in their stress factors and cooperative behavior. This fact indicates that these two user groups should be considered separately in development of a human-machine-interface for a cooperative driver assistance system.     «
