Research on the Influence of Smartphone Navigation on Driving Behavior Based on Real Vehicle Driving

Abstract EN

This paper discusses a study of the influence of different positions and modes of smartphone navigation devices on driving behavior based on real vehicle driving.

Twenty professional drivers participated in the experiment in free-flowing traffic and good weather conditions.

The eye movement and vehicle control data obtained in the experiment were used as indicators for evaluation.

Comparison of the mean, variance, and significance analysis shows that a smartphone navigation device placed on the right side of the car dashboard (position 1) has less impact on driving behavior than when placed above the air conditioning vent (position 2).

A smaller angle of view can increase the fixation frequency and the length of time that the driver spends looking out the windshield and reduce the range and time spent in glancing at the navigation device.

Using only sound navigation (the audio group in this paper) has the least influence on driving behavior because the driver’s visual attention is not transferred inside the vehicle rather than on the road ahead, and the vehicle is operated in the most stable state.

These findings have practical significance for reducing the negative influence of smartphone navigation.
