  7. Abstract:
  8. Intersections are recognized as critical points in urban transportation networks, and the yellow phase at signalized intersections, along with the dilemma zone before the intersection, is considered as a high-risk zone for drivers. Incorrect decisions made by drivers when passing through or stopping during the yellow phase can lead to irreparable conditions. Various factors influence this decision-making; the differing driving styles of individuals are among the main factors that significantly impact driver behavior in such situations. Additionally, age, gender, experience, and driving experience are other influential factors. Therefore, this study examines how the performance and decision-making of individuals vary during the yellow phase at intersections. To achieve this goal, a self-reported questionnaire was used to assess driving style and demographic information from several drivers. In the next stage, driver performance when passing through the intersection during the yellow phase was evaluated using video recording. The extraction of information from the camera was conducted with T-analyst software, and the analysis of data from these two sources was performed using SPSS software. By analyzing and merging these two data sources—self-reported data from the questionnaire and observed data from the video—a comprehensive understanding of driver behavior in critical traffic conditions, specifically during the yellow phase at intersections, can be obtained. Overall, the results indicate that women are more likely to fall into patient, anxious, and dissociative driving styles, while men tend to be categorized in more angry and risky driving styles. Individuals with careful, patient, and anxious driving styles tend to reduce speed to stop when observing the yellow phase, whereas those with high-velocity, angry, and risky driving styles tend to accelerate to pass through the intersection. The speed approaching the intersection during the yellow phase, distance from the stop line when observing the yellow phase, number of vehicles in front, and presence in a dilemma zone are among the most important variables influencing whether to pass through or stop when observing the yellow phase
