Most of the traffic related information of current active safety system transit to driver by Advanced driving assistance system (ADAS). These informations mainly represented as warning signal, and normally activated in potentially dangerous, near-crash or pre-crash situation and driver is incapable to make right decision due to the very short trigger time; present studies shows that increasing the driver’s awareness to traffic related information is an efficient method to improve road safety. Some initial researches already shown the potential benefits of using Three-dimensional (3D) sound information for enhance traffic environment awareness and human-machine interaction(HMI), by introducing designed In-Vehicle Information Systems (IVIS), the 3D sounds ADAS, the drivers can understand intuitively such as the type of the road user, the distance between driver and the movement course of objects, etc. Yet, to have an ergonomic design, to understand drivers’ behaviors and needs in drive context is the most priority work. The purpose of this study is to bring a real traffic context in terms of 3D sound and traffic video records into the design process, build up an dynamic communication tool for drivers and designers in order to involve both parties in the same context and enhance a better communication. In this study, a simulated 3D sound traffic experimental environment has been programmed, where the participants watched the traffic movie record filmed on real road while hearing the real time 3D sound which synchronized with. Focus group has been facilitated as an experimental tool for enabling the discussions and evaluating ideas and perspectives towards to 3D sound. In addition, two types of sound have been designed and put into the simulated 3D sound environment: abstract sound and natural sound. The main task include recreate virtual traffic environment in SFAER’s simulation room, designing four sets of different driving situation scenario with real traffic video clip which taken in China and Sweden; further, assess the effectiveness of 3D sound ADAS in purpose of represent the traffic information, for instance, represent the variety objects on the road through nature or abstract sound, as the meaning of increasing driver’s awareness of the traffic and driving status, reducing workload and bring an overall benefit in terms of road safety.
