Detection thresholds in car following situations and peripheral vision: implications for positioning of visually demanding in-car displays

摘要

This on-road study examined the effect of the positioning of an attentionally demanding in-car task on the driver's ability to detect the approach of a decelerating car ahead. Towelve participants aged between 19 and 27 years with an average of 18 170 km life-time driving experience drove 20 and 40 m behind a vehicle which decelerated form 50 km/h at ～0.7 m/s~2 without braking. Detection thresholds for nine locations of a LED display were compared with thresholds when focusing on the car ahead.
