Abstract:

The use of in-vehicle information system (IVIS) provides drivers with more comfortable driving environment, also makes them more easily distracted. The driver’s action distraction is defined based on the multiple resources theory. The car radio, CD, MP3 and navigator are chosen as the research object of IVIS, the influence of IVIS operations on driver action distraction are analyzed quantitatively based on the experimental test, and the significant factors of leading to action distraction are also analyzed. Results show that the traffic environment and IVIS operations have a significant influence on drivers action distraction; the car radio operation has a smaller effect on action distraction; MP3 adjustment leads that the time of hands off the steering wheel increases by more than 8.56%, and conflict or error rate increases by 9.72%; navigation path input leads that the time of hands off the steering wheel increases significantly, and conflict or error rate increases by 28.17%; voice route guidance makes the brake operation error increase.
