Driver’s Auditory Reaction Characteristics in Lane Change Behavior on Urban Expressway Based on Simulated Driving Experiment

In today’s rapid developments of intelligent transportation, voice navigation has been widely used. In order to reduce the risks of traffic safety caused by drivers’ delayed reactions to voice prompts at expressway exits, a simulated driving experiment was designed to study a driver’s auditory reaction characteristics during lane changes. A total of 90 experiments were conducted on 30 participants using a driving simulator, and experimental data was collected by D-Lab software to measure auditory reaction time. Measurements begin at the start of voice prompting for a lane change and the time point at which the angular velocity of steering wheel changes the most is the ending point. The experimental data is fitted with a normal distribution to obtain the expectation parameter of a driver’s auditory reaction time. We conclude that driving proficiency has the greatest influence on the driver’s auditory reaction characteristics.
