This study aims to understand distraction perceptions, including advertisements, their impact on behavior, and potential influences from advertisement type, in-vehicle distraction, and country factors (reflecting culture and environment). A standardized questionnaire was administered in Jordan and Kuwait, complemented by observations across three segment types: roadside advertisements, commercial signs, and road signs as control segments. Descriptive and inferential statistics were used. Results indicated a significant disparity in distraction perception between the two groups. Advertisement presence influenced Kuwaiti but not Jordanian behavior. Behavior varied by advertisement type in Jordan, not Kuwait, and in-vehicle distraction did not impact driver behavior. The study suggests explicitly revising advertising policies with a traffic safety focus. Overall, the study contributes insights into road user perceptions and behaviors, highlighting the complex interplay of distractions and advertising on road safety. Further research is required to validate these findings and shape road safety regulations.展开更多
为实现大规模角色运动场景的高真实感快速仿真,提出了一种基于动态纹理的可视化方法.使用基于关节点旋转角的动作迁移方法,获取角色的运动动作;使用基于曲线式骨骼的变形方法,实现运动角色变形;将角色运动过程,通过渲染到纹理技术,生成...为实现大规模角色运动场景的高真实感快速仿真,提出了一种基于动态纹理的可视化方法.使用基于关节点旋转角的动作迁移方法,获取角色的运动动作;使用基于曲线式骨骼的变形方法,实现运动角色变形;将角色运动过程,通过渲染到纹理技术,生成内容可以实时更新的动态纹理;将角色的动态纹理应用到Billboard上,替代运动角色,实现快速绘制;使用GPGPU(General Purpose on GPU)技术加速角色变形和绘制,进一步提高仿真速度.对于包含1万个角色的大规模场景,可以实现30 FPS的实时渲染,实验结果表明该可视化方法能够快速仿真大规模角色的运动场景.展开更多
