Abstract

Abstract: In order to ensure safety while crossing urban highways, experiments were conducted on Highway 110 using eye tracking glasses (ETG). The road was divided into highway section, adaptation section and urban section, and drivers' 17 concerns were classified into 7 categories. Then, their fixation and saccade characteristics on different sections were studied. The results show that drivers' fixation time on points of interest range from 134.29 to 449.07 ms, and it is longer in intersections and highway openings on highway section, which accounts for 7.54% of total time. Urban section features largest number of fixations, resulting in 14.42% of total fixation time, and points of regards like guidance and vehicle driving status category fail to attract drivers' attention. Landscape has the longest average time of attention on highway section, and total frequency of saccade in urban, adaptive, and highway sections gradually decrease with an average saccade angles of 11.44, 10.72 and 10.16° respectively.

Key words: crossing urban highways, driver, fixation characteristics, saccade characteristics, vehicle test
