Summary
This study addresses the limitations of in-vehicle traffic light systems for priority-controlled unsignalized intersections, where the failure to account for driver waiting time restricts practical applicability. At such intersections, minor-road drivers must yield to major-road traffic, and previous research indicates that drivers accept smaller gaps and take greater risks after prolonged waits. The authors propose an improved in-vehicle traffic light system that integrates waiting time into gap acceptance theory, adjusting the critical gap threshold dynamically: the critical gap decreases from 6.5 seconds to 5 seconds as waiting time increases from less than 10 seconds to over 30 seconds. The system also manages minor-road vehicle priority via a waiting list to prevent conflicts between oncoming minor-road vehicles. The research employed a driving simulator experiment with 12 male participants (average age 24.5 years) to evaluate driver behaviors under three minor-road conditions: no in-vehicle traffic light, in-vehicle traffic light without waiting time consideration, and in-vehicle traffic light with waiting time consideration. A separate major-road experiment assessed the impact on major-road drivers, who were required to react to minor-road vehicles entering the intersection. The simulator featured a six-degree-of-freedom motion platform and a 140-degree display, with traffic lights presented via a head-up display. Major-road traffic was congested to ensure minor-road drivers waited over 30 seconds. Data collected included maximum acceleration and lateral acceleration, blink rates, postencroachment time, and subjective evaluations of frustration and safety. Results indicated that the in-vehicle traffic light system considering waiting time significantly reduced the maximum acceleration stroke of minor-road vehicles compared to the no-assistance condition, suggesting a lower likelihood of aggressive driving. Additionally, maximum lateral acceleration was significantly decreased when waiting time was considered, indicating improved steering stability at the intersection. Statistical analysis using one-way repeated measures ANOVA confirmed these differences at p < 0.01. The study also measured blink rates and postencroachment times to assess driver workload and collision risk, respectively. The findings demonstrate that incorporating waiting time into the in-vehicle traffic light logic enhances driver behavior by promoting safer gap selection and reducing aggressive maneuvers, thereby improving the safety and practicality of virtual traffic light systems at unsignalized intersections.
