驾驶中使用手机对驾驶员行为安全绩效影响综述

驾驶中使用手机与交通事故之间存在着高度相关性。为揭示使用手机对驾驶行为安全绩效的影响,探索影响驾驶安全的理论机制,采取更有效的干预措施,结合近10 a来相关研究,综述了与驾驶安全密切相关的驾驶分心问题,主要包括:驾驶员分心的定义及其分类;使用手机对驾驶行为安全绩效的影响,如反应时(RT)、行车速度、路线保持和跟车距离;手机使用对驾驶员分心影响的理论机制,如信息加工理论和计划行为理论(TPB)。分析表明,使用手机会导致驾驶员的反应时延长15%～40%,驾驶路线发生明显偏移,对于行车速度减缓和跟车距离延长的假设需结合驾驶员主客观数据进行比较做进一步验证;驾驶过程中使用手机会增加驾驶员的认知负荷,TPB能够对使用手机行为进行有效的解释和预测,但对该理论中基于信念测量的研究还很少;除手机操作任务,影响驾驶员分心的其他操作任务还需做进一步的研究。     

基于贝叶斯结构方程模型的疲劳驾驶行为意图研究

为了深入探究影响驾驶员疲劳驾驶行为意图的心理因素,提高道路安全性,在计划行为理论的基础上,新增行为经验解释变量,形成扩展计划行为理论(Ex-TPB),构建了基于Ex-TPB的疲劳驾驶行为意图心理影响因素贝叶斯结构方程模型(Bayesian-SEM),并对比了传统结构方程模型(Traditional-SEM)与Bayesian-SEM的参数估计结果。最后,为有效防范疲劳驾驶行为提出了建议。结果表明:Ex-TPB可以有效解释和预测疲劳驾驶行为意图;在小样本的条件下Bayesian-SEM与Traditional-SEM相比,能得到更好的结果;对疲劳驾驶行为意图影响最大的因素为知觉行为控制,最小的是行为经验,且4种因素都显著正向影响疲劳驾驶行为意图。

道路交通环境中驾驶疲劳的生成模型研究

为预防由驾驶疲劳引起的交通事故,有必要研究在道路、交通和环境的综合影响下驾驶疲劳的生成机理。基于生理、心理学中的经典理论,借鉴国内外相关的研究成果,采用理论推理的方法对驾驶疲劳生成过程中驾驶员唤醒水平的变化规律及其影响因素进行分析。在此基础上建立了驾驶疲劳的生成模型,并将模型应用于工程实际。通过驾驶员唤醒水平的变化,指出驾驶疲劳的生成时刻,及其对驾驶时间的规定和道路、景观设计的影响。该模型以唤醒水平为核心,描述驾驶疲劳生成过程中驾驶员唤醒水平的变化规律,强调道路交通环境对驾驶员唤醒水平的影响。

Socio-demographic and experience factors affecting drivers’ runoff risk along horizontal curves of two-lane rural highway

Introduction: An improper driving strategy is one of the causative factors for a high probability of runoff and overturning crashes along the horizontal curves of two-lane highways. The socio-demographic and driving experience factors of a driver do influence driving strategy. Hence, this paper explored the effect of these factors on the driver’s runoff risk along the horizontal curves. Method: The driving performance data of 48 drivers along 52 horizontal curves was recorded in a fixed-base driving simulator. The driving performance index was estimated from the weighted lateral acceleration profile of each driver along a horizontal curve. It was clustered and compared with the actual runoff events observed during the experiment. It yielded high, moderate, and low-risk clusters. Using cross-tabulation, each risk cluster was compared with the socio-demographic and experience factors. Further, generalized mixed logistic regression models were developed to predict the high-risk and high to moderate risk events. Results: The age and experience of drivers are the influencing factors for runoff crash. The high-risk event percentage for mid-age drivers decreases with an increase in driving experience. For younger drivers, it increases initially but decreases afterwards. The generalized mixed logistic regression models identified young drivers with mid and high experience and mid-age drivers with low-experience as the high-risk groups. Conclusions: The proposed index parameter is effective in identifying the risk associated with horizontal curves. Driver training program focusing on the horizontal curve negotiation skills and graduated driver licensing could help the high-risk groups. Practical applications: The proposed index parameter can evaluate driving behavior at the horizontal curves. Driving behavior of high-risk groups could be considered in highway geometric design. Motor-vehicle agencies, advanced driver assistance systems manufacturers, and insurance agencies can use proposed index parameter to identify the high-risk drivers for their perusal.     

Effects of environment, vehicle and driver characteristics on risky driving behavior at work zones

This study aims to analyze the effects of environment, vehicle and driver characteristics on the risky driving behavior at work zones. A decision tree is developed using the classification and regression tree (CART) algorithm to graphically display the relationship between the risky driving behavior and its influencing factors. This approach could avoid the inherent problems occurred in the conventional logistic regression models and further improve the model prediction accuracy. Based on the Michigan M-94/I-94/I-94BL/I-94BR highway work zone driving behavior data, the decision tree comprising 33 leaf nodes is built. Bad weather, poor road and light conditions, partial/no access control, no traffic control devices, turning left/right and driving in an old vehicle are found to be associated with the risky driving behavior at work zones. The middle-aged drivers, who are going straight ahead in their vehicles with medium service time and equipped with an airbag system, are more likely to take risky behavior at lower work zone speed limits. Further, the middle-aged male drivers engage in risky driving behavior more frequently than the middle-aged female drivers. The number of lanes exhibits opposing effects on risky behavior under different traveling conditions. More specifically, the risky driving behavior is associated with the single-lane road under bad light or weather conditions while drivers are more likely to engage in risky behavior on the multi-lane road under good light conditions.

A neglected risky behavior among children and adolescents: underage driving and injury in New South Wales,Australia

PROBLEM: Among different causes of injury, roads and traffic-related incidents contributed most to all child deaths. The majority of childhood and adolescent traffic-related deaths are young people killed as pedestrians or bicyclists. Underage driving is a particular risky behavior much neglected. This study aimed to describe some characteristics related to motor-vehicle crashes and crash-related injury in which the vehicle was driven by a young person who was under the legal age of obtaining a learner license in New South Wales, Australia. METHODS: Data used in this study were made available from the Roads and Traffic Authority of NSW for the period between 1996 and 2000. Crash information was collected and reported by NSW police at the scene of these motor-vehicle crash incidents. RESULTS: There were 526 crashes involving an underage driver recorded within the study period. The majority (79.5%) of these underage drivers were males with slightly more than half (58.0%) aged 15 years, and nearly 30% aged 14 years. Among these, 83.6% involved the driver of the vehicle being killed or injured. Among the injured or killed passengers, 128 (73.6%) were nonadult passengers under the age of 18 years. Seventy of these crashes occurred while the car was in pursuit by police. The adjusted relative risk of injury to at least one occupant in the vehicle should a crash occur for female underage drivers was two times (OR=2.01, 95% CI=1.27-3.20) as compared to male underage drivers. DISCUSSION: Underage driving poses a serious problem in terms of crash outcomes. Experimental driving and late-night outings for adolescents should be discouraged. Well-designed studies are required to further investigate the relationship between underage driving and on road risk-taking behavior among licensed adolescents. IMPACT ON INDUSTRY: Data obtained from this study indicate that adults, particularly parents, should discourage underage adolescents from experimenting driving and should actively cultivate a positive attitude toward driving.     

The prediction of safe lifting behavior: an application of the theory of planned behavior

PROBLEM: Injuries resulting from lifting are costly, and create significant pain and discomfort. While engineering controls are the most effective means of reducing risks, most organizations continue to rely on manual lifting techniques. The problem, however, is that the use of safe-lifting techniques is inconsistent and managers have a difficult time motivating use of these techniques. Consequently, it is important to understand the factors driving safe-lifting behaviors. METHODS: This study used a survey to apply the theory of planned behavior (Ajzen., I., 1991. The theory of planned behavior. Organization Behavior and Human Processes, 50, 179-211) to safe-lifting among 136 materials management employees at a heavy manufacturing organization. Structural equation modeling and factor analysis were employed to analyze relationships among constructs. RESULTS: Results revealed that perceived behavioral control and intention were the strongest predictors of safe-lifting behavior. Subjective norms, to a lesser degree, were also important influences on intention. Attitudes did not surface as effective direct predictors of safe-lifting behavior, but did affect behavior and intent via mediating factors (subjective norms and perceived behavioral control). Finally, the theory of planned behavior was supported as an effective model explaining safe-lifting behavior, and had potential application for many other safety-related behaviors. IMPACT ON INDUSTRY: Results from this study emphasize the importance of perceived behavioral control as a factor associated with safety-related behavior.
