Abstract
The interval changes in yellow light signals significantly impact driving behaviors that affect traffic safety. This study aims to compare the applicability of different interval changes in yellow light signals from the perspectives of drivers. Data acquisition was conducted in a naturalistic driving experiment with equipment including V-BOX, Ergo LAB, and I-View HED4 to acquire vehicle running index data, driver physiological and psychological index data, and eye movement index data, respectively. Twenty experienced drivers were recruited as subjects and were categorized as safe, average, or dangerous drivers. Based on the data obtained, driving behaviors for different interval changes in yellow light signals were studied using an Atlas. Observations of the driving behavior Atlas reveal that there are notable differences in driving behaviors for different interval changes in yellow light signals. Also, it was found that dangerous drivers are more likely to be affected by the interval changes in yellow light signals. It is necessary to choose reasonable signal transition modes to improve the safety of intersections based on actual road conditions and types of drivers. The results can guide traffic management departments when choosing a reasonable transition method for yellow light signals and help formulate customized training programs for different types of drivers. In particular, the results help in providing training on driving speed and deceleration control for dangerous drivers, which will help improve traffic safety.
Highlights
Traffic problems of urban roads are mainly concentrated on intersections of the spatial dimension, and in the time dimension during the signal transition period
Ensuring traffic safety during the yellow light signal transition period at intersections is key to improving the overall operational efficiency of urban traffic [1]

Summary
Traffic problems of urban roads are mainly concentrated on intersections of the spatial dimension, and in the time dimension during the signal transition period. Inappropriate settings of interval changes in yellow light signals at intersections often result in an increase in signal loss time and a decrease in effective green light time. Traffic efficiency at urban road intersections is reduced and the problem of urban road traffic congestion is aggravated as a result. Ensuring traffic safety during the yellow light signal transition period at intersections is key to improving the overall operational efficiency of urban traffic [1]. A driver’s behavior is closely related to traffic control measures [3]. Current traffic laws do not have clear restrictions on the behavior of ‘‘running the yellow
