驾驶经验和危险类型对年轻驾驶员危险知觉的影响（英文）

结合反应时和眼动测量方法,采用驾驶经验分组2(年轻新手驾驶员,年轻有经验驾驶员)×危险类型2(明显危险,隐藏危险)的混合实验设计,探索年轻驾驶员危险知觉的经验优势是否随着危险类型的不同而变化。使用一个基于真实交通情境视频的驾驶员危险知觉任务,对27名年轻新手驾驶员和22名年轻有经验驾驶员进行测试,并使用Tobbi T120记录眼动数据。结果发现,总体上,年轻新手驾驶员对潜在道路危险的反应次数比年轻有经验驾驶员更少,反应时间也更慢。两组驾驶员反应时间的差异,随着危险类型的不同而来源于不同的加工阶段。具体来说:一方面,年轻新手驾驶员对明显危险的反应时间慢,是因为他们对该类危险的评估时间长。另一方面,年轻新手驾驶员对隐藏危险的反应时间慢,是因为他们对该类危险的识别时间长。两组驾驶员对危险的平均注视时间受测试中危险类型的影响但不受驾驶经验的影响。这些研究结果表明,在对年轻新手驾驶员进行危险知觉训练或测试时,应重视危险类型对他们危险知觉的影响。.     

自我评估的能力与驾驶经验对危险知觉的影响

结合反应时和眼动研究方法,采用驾驶经验2（新手,有经验）×自我评估的能力2（高,低）×危险类型2（明显,隐藏）的混合实验设计,探索驾驶员驾驶能力的自我评估和驾驶经验对危险知觉及视觉注意的影响。采用驾驶能力量表和基于动态交通视频的危险知觉任务对86名驾驶员测试,并使用Tobbi T120记录眼动数据。结果发现,新手和有经验驾驶员自我评估的能力与危险知觉反应时间之间相关不显著,这说明两组驾驶员对自己驾驶能力的认识和评估不准确。有经验驾驶员对两类危险的反应比新手快。新手自我评估的能力过高,他们对两类危险的反应比同龄驾驶员和有经验驾驶员慢。然而,有经验驾驶员自我评估的能力与危险知觉反应时间之间不存在显著差异。此外,与新手相比,有经验驾驶员对两类危险的首次注视较快,总注视时间更长。与同龄驾驶员相比,新手自我评估的能力过高,他们对危险的首次注视较慢,对危险的总注视时间更少。这些研究结果表明,新手自我评估的能力过高,可能会提高他们的风险接受阈限,由此降低了他们对危险的反应速度。未来驾驶训练应当采取措施减少新手对驾驶能力的自我评估偏见,改善他们的视觉搜索模式以降低事故风险。     

驾驶经验和危险类型对驾驶员危险检测的影响

结合反应时和信号检测方法,考察不同危险类型下驾驶员危险检测的特点。35名新手和35名有经验驾驶员依次完成一个反应时测试和一个信号检测任务。结果发现：新手对明显和隐藏危险的反应时间比有经验驾驶员长。与隐藏危险相比,驾驶员对明显危险的敏感性高、判断标准低。驾驶员对两类危险的反应时间长是因为他们的判断标准严格。研究结果表明,驾驶员危险检测的特点随着危险类型不同而变化。

危险类型对公交驾驶员危险知觉的影响

结合反应时方法和多维度驾驶风格量表,以140名公交驾驶员为研究对象,采用2（危险类型：隐藏危险、明显危险）×2（驾驶员分组：有无交通违规/事故记录）的混合实验设计考察危险类型对危险知觉的影响。结果发现：驾驶员对明显危险的反应时比隐藏危险短,无交通违规/事故记录驾驶员对明显和隐藏危险的反应时均比有交通违规/事故记录驾驶员短。控制驾驶风格后,危险类型主效应不再显著。结果表明,公交驾驶员危险知觉的特点随着危险类型不同而变化。     

车辆追随条件下驾驶员知觉行人危险的经验优势

危险知觉是指驾驶员在交通情境中对明显危险和潜在危险的识别、预测和反应的认知加工过程,是驾驶员对当前交通情境形成的连续而富于变化的复合认知表征。以往研究表明,对于行人过马路这类明显危险,新手和经验驾驶员危险知觉表现都非常出色。但是当明显危险（行人）和潜在危险（前车制动）并存时,经验驾驶员对明显危险的知觉反应是否会突显出优势呢？本研究通过设置两种交通场景：行人单一危险条件和行人-前车双重危险条件,考察不同经验人群对行人危险的反应及眼动特点。在第一个研究中,使用Tobii T120型眼动仪,通过反应时和眼动结合的方法,考察不同危险场景中,不同驾驶经验对驾驶员知觉行人危险的行为反应数据（反应时和正确率）及眼动指标（平均注视时间和水平搜索广度）的影响。采用2（交通场景：行人场景、行人-前车场景）×3（组别：无驾照组、新手组、经验组）两因素混合实验设计,其中交通场景是组内变量,组别为组间变量。因变量为驾驶员对行人危险进行反应的行为数据（反应时和正确率）及眼动数据（平均注视时间和水平搜索广度）。实验要求被试观看交通场景视频,当发现危险时,立刻按键反应。实验结果表明：在有前车条件下,经验组被试的反应时快于新手组（p=.039）和无驾照组（p=.013）,F(2,30)=3.98,p=.029。无驾照组被试对行人的平均注视时间长于经验组（p=.043）和新手组（p=.024）,F(2,30)=3.39,p=.047,ηp2= .18。无驾照组被试对场景的水平搜索广度均小于经验组（p=.006）和新手组（p=.016）,F(2,30)=5.17,p=.012,ηp2= .26。在第二个研究中,对研究一的数据进行了深入分析,考察双重危险场景中驾驶经验对驾驶员知觉行人危险及信息加工效率的影响。采用2（兴趣区类型：行人、前车）×3（组别：无驾照组、新手组、经验组）两因素混合实验设计,其中兴趣区类型是组内变量,组别为组间变量。因变量为搜索行人和前车时的眼动数据（总注视时间、搜索次数和平均搜索时间）。研究结果表明：经验组驾驶员对前车的总注视时间显著短于新手组（p=.014）和无驾照组（p=.003）,F(2,30)=5.99,p=.006。经验组驾驶员对前车的平均搜索视时间显著短于新手组（p=.014）和无驾照组（p=.004）,F(2,30)=5.50,p=.009。在有前车条件下,控制了性别、年龄后,驾驶员对前车的平均搜索时间越长,对行人的危险反应时越长（β=.393,p＜0.05,R2=.308）。这些结果说明：无经验和新手驾驶员糟糕的搜索行为不仅仅是由于操作抢夺认知资源或者情绪紧张导致的。危险的信息加工效率更低,搜索模式不够灵活,也是导致新手驾驶员行人碰撞事故率更高的原因之一。驾驶员培训有助于提高驾驶员对明显危险的信息加工效率和搜索模式灵活性。积累更多的驾驶经验可以提升驾驶员对潜在危险的的视觉搜索和注意资源分配效率,从而加快危险反应时间。未来的驾驶员培训应加强对新手驾驶员搜索技能的培训,并持续提供更多的驾驶员继续教育机会。     

影响驾驶安全的驾驶员危险知觉研究述评

危险知觉是指驾驶员对交通情境中的潜在危险进行识别并做出反应的一种能力。目前,驾驶员危险知觉测量主要使用反应时、眼动或主观评定三种测量方法。在测量中,这三种方法各有优缺点,并出现相互结合的研究趋势。为了提高我国交通安全性,结合国外在提高驾驶员危险预期能力和改善视觉搜索模式两个方面的应用研究,未来国内研究可以在探索危险知觉的认知加工特点、影响因素及加快测量技术的商品化应用等方面加以深入。     

驾驶员危险知觉训练研究述评

危险知觉是指驾驶员预测前方道路危险情况的能力,即对某个具体的危险做出反应的快慢。驾驶员的危险知觉能力是影响驾驶安全的重要因素,因此,对危险知觉进行训练就显得尤为重要。文章主要介绍了基于驾驶模拟器和基于电脑两方面的危险知觉训练方式。详细介绍了训练方式的定义、机制以及具体实施过程,并指出了未来的研究方向。     

年轻新手驾驶员驾驶风格特点研究

为了探索年轻新手驾驶员驾驶风格的特点,采用多维度驾驶风格量表对182名驾驶员进行测试。结果发现,感觉寻求,愤怒和冒险的性别差异显著。新手驾驶员受教育程度越高,感觉寻求,愤怒和冒险得分越低。新手驾驶员感觉寻求、焦虑、冒险和愤怒驾驶风格对交通违规具有预测作用。     

通过摩托车驾驶模拟器评估驾驶经验和高级训练的效果

机动车驾驶员中包含着一部分群体,即摩托车驾驶员。在现实生活中很多家庭采用这样的交通工具来方便他们的生活。我们探究的重点一直侧重于其他机动车驾驶员,却忽视了这类没有车身可以保护驾驶员的摩托车驾驶群体。数据表明,在机动车事故中,摩托车撞击事故占有一定的比例,虽然一部分关于摩托车的事故可能是由于其他道路使用者所引起的,但是许多灾祸和伤亡是由于骑车者导致的。由于提升摩托车驾驶员的驾驶经验可以提升他们的驾驶技术,而高级训练可能能够唤起更多的安全驾驶行为。因此本文采用摩托车驾驶模拟器来评估驾驶经验和高级训练的重要性。摩托车驾驶模拟器监测新手摩托车驾驶员,有经验的摩托车驾驶员以及之前在真实世界道路上体验过各种速度和曲度的道路的受训摩托车驾驶员的速度和车道位置。本文采用改变不同摩托车驾驶员的速度和道路类型来说明驾驶经验和高级训练的效果。研究表明,受训驾驶员和有经验的驾驶员相较于新手驾驶员来说有行为上的变化,这样对于驾驶安全有了一个潜在的积极影响。     

A method to improve the hazard perception of young novice drivers based on Bandura’s observational learning theory: Supplement to expert commentary training

Compared with experienced drivers, young novice drivers are more likely to have traffic accidents. The main reasons are that they lack experience, their hazard perception is weak, and their visual search strategy is underdeveloped. Research shows that hazard perception training can improve the visual search strategy of young novice drivers and enhance their hazard perception ability. We propose that a driver's visual search behaviour, like any other action, can be developed by observing the behaviour of a role model. In an experiment based on a driving simulator, we clustered the visual search paths of 20 experienced drivers, selected the drivers with the best visual search behaviour, and obtained visual search path video footage to produce hazard perception training videos. Using these videos, we applied Bandura’s observation learning theory to train 20 young novice drivers. We call this approach “training based on experienced drivers' performance”. To determine the effects of training based on experienced drivers' performance, 20 young novice drivers were given the usual expert commentary training, and 20 young drivers were given no training. The results showed that training based on experienced drivers' performance and expert commentary training had positive effects on the average speed of young novice drivers through hazard sections. Compared with untrained young novice drivers, trained young novice drivers decreased their speed in response to dangerous road sections. Compared with young novice drivers who received expert commentary training and those who did not receive training, young novice drivers who received training based on experienced drivers' performance showed significant improvements in visual search. These results suggest that training based on experienced drivers' performance can help young novice drivers improve their hazard perception, especially in visual aspects. This training method can complement existing training methods for young novice drivers.     

The development of hazard perception: Dissociation of visual orientation and hazard processing

Eye movements are a key behavior for visual information processing in traffic situations and for vehicle control. Previous research showed that effective ways of eye guidance are related to better hazard perception skills. Furthermore, hazard perception is reported to be faster for experienced drivers as compared to novice drivers. However, little is known whether this difference can be attributed to the development of visual orientation, or hazard processing. In the present study, we compared eye movements of 20 inexperienced and 20 experienced drivers in a hazard perception task. We separately measured (a) the interval between the onset of a static hazard scene and the first fixation on a potential hazard, and (b) the interval between the first fixation on a potential hazard and the final response. While overall RT was faster for experienced compared to inexperienced drivers, the scanning patterns revealed that this difference was due to faster processing after the initial fixation on the hazard, whereas scene scanning times until the initial fixation on the hazard did not differ between groups.     

Young drivers’ perception of hazards: Variation with experience and day versus night

Young novice drivers have a relatively high crash risk for several years following initial licensing, and while all drivers are at greater risk at night, the night-time increase is greater for inexperienced drivers. Poor hazard perception has been identified as an important contributor to inexperienced drivers’ risk, but research on day-night differences in hazard perception for drivers varying in experience is lacking. This exploratory study investigated the nature of hazards reported by young inexperienced drivers versus more experienced and slightly older drivers. Hazards were not pre-identified by researchers; participants were simply provided with a general definition of ‘hazard’. Analysis focused on how experience level affected qualitative differences in the kinds of hazards reported, with particular focus on day-night differences.The 53 participants ranged in driving experience from learners through to 5+years post licensing, and in age from 16 to 30 years. They viewed 14 day- and night-time video clips of a diverse range of driving situations, pausing the video whenever they identified a hazard and then explaining why they had paused it at that point. Their responses were recorded. Content analysis of responses showed that more experienced drivers reported visibility-related hazards significantly more often than inexperienced ones, and significantly more so at night. They also commented significantly more on hazards related to tight bends in the road and significantly less on hazards concerning compliance with rules. Comments tended to be fewer with higher vehicle speeds, particularly for the least experienced drivers.Results are discussed in terms of how experience-related differences in drivers’ cognitive schemata and mental models are likely to affect hazard perception and crash risk, particularly at night. Some implications for driver training and license testing are suggested.     

Are situation awareness and decision-making in driving totally conscious processes? Results of a hazard prediction task

Detecting danger in the driving environment is an indispensable task to guarantee safety which depends on the driver’s ability to predict upcoming hazards. But does correct prediction lead to an appropriate response? This study advances hazard perception research by investigating the link between successful prediction and response selection. Three groups of drivers (learners, novices and experienced drivers) were recruited, with novice and experienced drivers further split into offender and non-offender groups. Specifically, this works aims to develop an improved Spanish Hazard Prediction Test and to explore the differences in Situation Awareness, (SA: perception, comprehension and prediction) and Decision-Making (DM) among learners, younger inexperienced and experienced drivers and between driving offenders and non-offenders. The contribution of the current work is not only theoretical; the Hazard Prediction Test is also a valid way to test Hazard Perception. The test, as well as being useful as part of the test for a driving license, could also serve a purpose in the renewal of licenses after a ban or as a way of training drivers. A sample of 121 participants watched a series of driving video clips that ended with a sudden occlusion prior to a hazard. They then answered questions to assess their SA (“What is the hazard?” “Where is it located?” “What happens next?”) and DM (“What would you do in this situation?”). This alternative to the Hazard Perception Test demonstrates a satisfactory internal consistency (Alpha = 0.750), with eleven videos achieving discrimination indices above 0.30. Learners performed significantly worse than experienced drivers when required to identify and locate the hazard. Interestingly, drivers were more accurate in answering the DM question than questions regarding SA, suggesting that drivers can choose an appropriate response manoeuvre without a totally conscious knowledge of the exact hazard.
