Audio-visual perception of vehicles in traffic, phase 2

交通车辆的视听感知,第二阶段

基本信息

项目摘要

In the second phase of AUDICTIVE, our project continues to investigate the role of auditory perception and cognition for safe mobility, by studying judgments of time-to-collision (TTC; "When will the vehicle arrive at my position?") and street-crossing decisions from a pedestrian's perspective. For this, we use the interactive and realistic audio-visual virtual-reality simulations of electric and conventional vehicles approaching pedestrians in a street-crossing scenario that were implemented in the first phase, and we will refine and extend the simulations systems. The objective of work package (WP) A is to understand the perceptual mechanisms underlying the beneficial effects of the sound of accelerating vehicles with internal combustion engine (ICE) on TTC estimation and street-crossing decisions that were consistently observed in phase 1. WP B investigates the auditory perception of distance, velocity, and acceleration, for the specific case of approaching vehicles. The aim is to explain the cue weights in TTC estimation and street-crossing decisions observed in project phase 1 and in WP A based on the auditory sensitivity in the basic tasks, and conditional on the availability of different acoustic cues. Because the results of phase 1 showed a significantly smaller benefit of the sound of accelerating electric vehicles, even with acoustic vehicle alerting system (AVAS), WP C investigates how AVAS designs can be improved so that they provide acceleration information as effectively as the sound of an ICE vehicle. Plausibility of the traffic situations and events, which are portrayed within an immersive virtual reality system, can play an important role on the traffic safety and sound quality investigations. Design aspects and the complexity of the VR environment have an influence on the perceived overall plausibility of these virtual-reality-based simulations. The effect of complexity on plausibility ratings and behavior of subjects will be investigated in experiments on TTC-estimation and street-crossing decisions. First, in WP D, the complexity of virtual sound sources is increased by taking into account the directional characteristics of vehicle sub-sources. For this purpose, a new vehicle recording method is developed, based on which new virtual source models are created. WP E focuses on the complexity of scene content, from an empty street to the complexity of a lively street, and the influence of auditory simulation accuracy on plausibility. Finally, WP F investigates the influence of additional technical and social distraction factors on the plausibility evaluation and behavior of the subjects by giving them additional tasks with smartphones or interactions with people during traffic safety experiments.
在AUDICTIVE的第二阶段,我们的项目继续研究听觉感知和认知对安全移动的作用,通过研究碰撞时间的判断(TTC;“车辆何时到达我的位置?“),以及从行人的角度考虑过马路的决定。为此,我们使用在第一阶段实施的过街场景中接近行人的电动和传统车辆的交互式和逼真的视听虚拟现实模拟,我们将改进和扩展模拟系统。工作包(WP)A的目的是了解感知机制的有利影响的声音加速车辆与内燃机(ICE)TTC估计和过街的决定,一直观察到在第1阶段。WP B针对接近车辆的特定情况研究了距离、速度和加速度的听觉感知。其目的是解释的线索权重TTC估计和过街的决定,观察项目阶段1和WP A的基础上的听觉灵敏度的基本任务,并有条件的不同的声学线索的可用性。由于第一阶段的结果显示,即使使用声学车辆报警系统(AVAS),电动汽车加速时的声音也明显较小,因此WP C研究了如何改进AVAS设计,以便它们能够像ICE车辆的声音一样有效地提供加速度信息。在沉浸式虚拟现实系统中描绘的交通状况和事件的可信性可以在交通安全和声音质量调查中发挥重要作用。设计方面和VR环境的复杂性对这些基于虚拟现实的模拟的整体可感知性有影响。在TTC估计和过街决策的实验中,将研究复杂性对受试者的可接受性评级和行为的影响。首先,在WP D中,通过考虑车辆子源的方向特性来增加虚拟声源的复杂性。为此,开发了一种新的车辆记录方法,在此基础上创建了新的虚拟源模型。WP E关注场景内容的复杂性,从一条空荡荡的街道到一条热闹街道的复杂性,以及听觉模拟精度对可解释性的影响。最后,WP F研究了额外的技术和社会分散因素对受试者的可接受性评估和行为的影响,方法是在交通安全实验中给他们额外的智能手机任务或与人的互动。
