在日本，所有车辆都在道路左侧行驶。右转交通是十字路口最危险、最有问题的交通，因为右转司机必须判断迎面车流的车距并避开人行横道上的行人。在十字路口，不给行人让路会导致车辆与行人的冲突。这项研究的目的是调查驾驶员在右转交通前方人行横道上检测行人的理解能力。夜间在日本筑波国家土地和基础设施管理研究所的实验室进行了能见度实验。结果表明，停在人行横道后方的汽车前灯状态对检测行人的能见度有很大影响。根据我们的结果，当前灯打开时，右转司机几乎看不到进入人行横道之前位置的行人。建议提高该位置的路灯照明，并将右转车辆的前灯朝向该位置，作为减少交叉路口行人车辆碰撞事故的对策。研究发现，老年驾驶员在夜间检测行人的能力不如年轻驾驶员敏感。总体而言，增加十字路口的垂直照度是减少行人车辆事故的一种改进方法。
In Japan, all vehicles travel on the left side of the road. Right-turn traffic is the most dangerous and problematical traffic at an intersection since a right-turning driver has to judge the traffic gap of oncoming traffic stream as well as avoid pedestrians in the crosswalk. At intersections, failure to yield the right of way to pedestrians causes vehicle-pedestrian conflicts. The objective of this research was to investigate driver comprehension in detecting pedestrians at a crosswalk ahead of right-turning traffic. A visibility experiment was conducted during nighttime in the laboratory of the National Institute for Land and Infrastructure Management in Tsukuba, Japan. The results show that state of headlight of the car stopped behind pedestrian crossing had a high influence on the visibility for detecting pedestrians. According to our results, when the headlight was on, the pedestrian in the position of before entering into the crosswalk was hardly visible to the right-turning drivers. Brightening the road light illumination at this location and directing the headlights of right-turning vehicles towards this location are recommended as counter-measures to reduce pedestrian-vehicle crashes at intersections. Older drivers' ability in detecting pedestrians during nighttime was found to be less sensitive than that of younger drivers. Overall, increasing vertical illuminance at intersections is being proposed as an improvement method to decrease pedestrian-vehicle accidents.
