Same, Same but Different: How Design Requirements for an Auditory Advisory Traffic Information System Differ Between Sweden and China

Many advanced driving assistance systems have been developed based on the western automobile markets. However, it is widely known that the differences between Western and Asian markets are large in terms of traffic safety culture, traffic situation, and driver behavior. This study aimed to explore the differences between Swedish and Chinese drivers' information requirements in regards to a 3D Auditory Advisory Traffic Information System design (3DAATIS). A total of 46 participants took part in the study. The results showed that both Swedish and Chinese drivers appreciated the concept of a 3DAATIS. Moreover the two groups expressed similar information needs when interacting with a single road user, e.g. giving higher priority to vulnerable road users. In contrast, they expressed different information requirements in complex traffic scenarios. The results further imply that identifying drivers' requirements under different traffic scenarios can be a feasible approach to successful cross-regional adaption design.
