Abstract

This study aims to elucidate the impact of A-pillar blind spots on drivers' visibility of pedestrians during left and right turns at an intersection. An experiment was conducted using a sedan and a truck, with a professional test driver participating. The driver was instructed to maintain sole focus on a designated pedestrian model from the moment it was first sighted during each drive. The experimental results revealed how the blind spots caused by A-pillars occur and clarified the relationship between the pedestrian visible trajectory distance and specific vehicle windows. The results indicated that the shortest trajectory distance over which a pedestrian remained visible in the sedan was 17.6 m for a far-side pedestrian model during a right turn, where visibility was exclusively through the windshield. For the truck, this distance was 20.9 m for a near-side pedestrian model during a left turn, with visibility through the windshield of 9.5 m (45.5% of 20.9 m) and through the passenger-side window of 11.4 m (54.5% of 20.9 m). Additionally, we quantified the trajectory distances where pedestrians became invisible when the driver's view was obstructed by A-pillars. The sedan exhibited the highest invisibility rate at 46.1% for a far-side pedestrian model during a right turn, followed by the truck at 17.8% for the same model. These findings will be instrumental in developing new driving support systems aimed at enhancing visibility in situations where pedestrians are obscured by A-pillars.

十字路口车辆转弯时,A 柱盲点对驾驶员行人视线的影响。
本研究旨在阐明 A 柱盲区对驾驶员在交叉路口左转和右转时看到行人的影响。实验使用了一辆轿车和一辆卡车,由一名专业测试驾驶员参与。驾驶员被要求在每次驾驶过程中,从第一眼看到指定的行人模型开始,就将注意力完全集中在该模型上。实验结果揭示了由 A 柱造成的盲区是如何产生的,并阐明了行人可见轨迹距离与特定车窗之间的关系。结果表明,对于右转时完全通过挡风玻璃看到的远侧行人模型,轿车中行人保持可见的最短轨迹距离为 17.6 米。卡车左转时,近侧行人模型的可见距离为 20.9 米,其中通过挡风玻璃的可见距离为 9.5 米(20.9 米的 45.5%),通过乘客侧车窗的可见距离为 11.4 米(20.9 米的 54.5%)。此外,我们还量化了当驾驶员视线被 A 柱遮挡时行人变得不可见的轨迹距离。在右转弯时,远侧行人模型中轿车的隐形率最高,为 46.1%,其次是同一模型中卡车的隐形率为 17.8%。这些发现将有助于开发新的驾驶辅助系统,以提高行人被 A 柱遮挡时的可见度。
