Abstract

This study was designed to gain insight into the influence of performing different types of secondary task while driving on driver eye movements and to build a safety evaluation model for secondary task driving. Eighteen young drivers were selected and completed the driving experiment on a driving simulator. Measures of fixations, saccades, and blinks were analyzed. Based on measures which had significant difference between the baseline and secondary tasks driving conditions, the evaluation index system was built. Method of principal component analysis (PCA) was applied to analyze evaluation indexes data in order to obtain the coefficient weights of indexes and build the safety evaluation model. Based on evaluation scores, the driving safety was grouped into five levels (very high, high, average, low, and very low) using K-means clustering algorithm. Results showed that secondary task driving severely distracts the driver and the evaluation model built in this study could estimate driving safety effectively under different driving conditions.

Highlights

With the increasing use of in-vehicle information systems (IVIS) in cars, an understanding of the safety implications of secondary tasks is becoming more and more crucial
The overall goal of this paper is to examine the influence of different secondary tasks on driver eye movements and develop a method to evaluate the safety for secondary task driving
The goal of this research was to gain insight into how human eye movements changed while interacting with different types of secondary task while driving and build the driving safety evaluation model based on these measures

Summary

Introduction

With the increasing use of in-vehicle information systems (IVIS) in cars, an understanding of the safety implications of secondary tasks is becoming more and more crucial These systems could place demands on drivers that might lead to distraction and diminish capacity to perform driving tasks. According to the report of World Health Organization, many countries have attached great importance to such activities and have taken effective measures to prohibit multitask driving. Countries such as United States, China, and Canada have enacted laws banning the use of hand-held cell phone, text messaging, hand-held GPS, or mapping services while driving. Research is still needed on the effects of using in-vehicle hands-free devices on driver performance
