道路交通常见事故案例及其原因

对于生产经营单位来说,车辆运输安全包括社会道路行驶的车辆运输安全及厂内车辆行驶、流动机械运输安全等.运输车辆分机动车和非机动车.机动车是指动力装置驱动的车辆,流动机械也属于机动车;非机动车是指人力驱动的车辆. 厂内车辆、流动机械具有特定场所行驶、用途广泛的特点;作业人员在行驶时应注意来往车辆,遵守厂内道路交通规则和安全技术操作规程;作业人员与车辆配合作业时,应注意作业车辆动态,与车辆保持一定的安全距离;作业人员不准搭乘流动机械;严禁无关人员进入搬运、流动机械安全警示区.     

基于ISM的道路交通安全影响因素研究

为提高交通安全管理水平,促进交通的可持续发展。基于解释结构模型原理,综合考虑车、路和环境因素,构建了影响道路交通安全的影响因素结构模型。该模型不但能够弥补分析结构要素之间内在影响机制的不足,而且对于研究道路交通安全结构要素之间的层次性和复杂性有天然的优势。数据来源于由13位专家构成的ISM小组,其中7位为来自高校从事交通安全研究的教授,6位为来自北京市、上海市、广州市、武汉市等交通运输委员会的高层管理者,保证了数据的科学性和可靠性。采用解释结构图分析车、路和环境各影响因素之间的关系,结果表明,众多因素会对道路交通安全产生影响,车辆技术条件、定期检验合格率、车辆救援设备的完备状况、安全设施是制约道路交通安全的直接影响因素,道路限速、道路负荷度、大客(或货车)比例、交通量、交通监控是影响道路交通安全的间接因素,车辆超限(超载)状况、车流密度、道路路面类型、道路设施完备性、天气状况、单向车道数和地形特征是影响道路交通安全的最根本因素。为提高道路交通安全管理水平,首先,应进一步完善《道路交通安全法实施条例》,加强对车辆定期检验的监督;其次,健全道路信息公示制度,提升交通监控水平,引入相关路段道路限速、负荷度、交通量动态信息显示及预警机制;最后,加强车辆超限(超载)及车流密度的监控,健全道路设施的配套制度。

基于系统安全观的道路交通安全立法体系重构研究

介绍和分析现代道路交通安全治理的3种思想。应用其中非常值得我国借鉴的系统治理思想对现行道路交通安全立法进行分析。现行道路交通安全立法仅围绕驾驶人的行为控制而设计,围绕道路交通安全管理部门的职能而展开,在很大程度上局限于道路交通秩序管理,在体系上存在缺失,影响道路交通安全治理的工作及其成效。基于当前形势分析,我国有必要也有条件借鉴道路交通安全系统治理的先进思想,重新构建道路交通安全立法的体系。该体系的重构需从道路安全保障、车辆安全保障、交通秩序管理、运输安全运营、交通事故处理等5个方面展开。

Road traffic crashes among farm vehicle drivers in southern China: A cross-sectional survey

Objective: The objective of this study was to identify the prevalence and potential risk factors of farm vehicle–related road traffic crashes among farm vehicle drivers in southern China.

Methods: A cross-sectional study was used to interview 1,422 farm vehicle drivers in southern China. Farm vehicle–related road traffic crashes that occurred from December 2013 to November 2014 were investigated. Data on farm vehicle–related road traffic crashes and related factors were collected by face-to-face interviews.

Results: The prevalence of farm vehicle–related road traffic crashes among the investigated drivers was 7.2%. Farm vehicle–related road traffic crashes were significantly associated with self-reported vision problem (adjusted odds ratio [AOR] = 6.48, 95% confidence interval [CI], 3.86–10.87), self-reported sleep disorders (AOR = 10.03, 95% CI, 6.28–15.99), self-reported stress (AOR = 20.47, 95% CI, 9.96–42.08), reported history of crashes (AOR = 5.40, 95% CI, 3.47–8.42), reported history of drunk driving (AOR = 5.07, 95% CI, 2.97–8.65), and reported history of fatigued driving (AOR = 5.72, 95% CI, 3.73–8.78). The number of road traffic crashes was highest in the daytime and during harvest season. In over 96% of farm vehicle–related road traffic crashes, drivers were believed to be responsible for the crash. Major crash-causing factors included improper driving, careless driving, violating of traffic signals or signs, and being in the wrong lane.

Conclusion: Findings of this study suggest that farm vehicle–related road traffic crashes have become a burgeoning public health problem in China. Programs need to be developed to prevent farm vehicle–related road traffic crashes in this emerging country.

The effect of fatigue driving on injury severity considering the endogeneity

IntroductionFatigue driving is one of the most risky driving-related behaviors and represented a significant social and economic cost to the community. Several studies have already examined the relationship between fatigue driving behavior and traffic injury severity from different aspects. However, fatigue driving and injury severity in traffic crash may share some common influential factors. Ignoring the impact of these common factors will lead to endogeneity problem and result in biased parameter estimation.MethodBased on 38,564 crash records during 2006–2011 in Guangdong province, China, we apply a bivariate endogenous binary-ordered probit model to examine the relationship between fatigue driving and injury severity considering endogeneity of fatigue driving. We also explore the difference of influential factors between commercial and non-commercial vehicle drivers.ResultsThis study identifies several common observed influential factors of fatigue driving propensity and fatal injury propensity and reveals a substantial and significant negative correlation of unobserved factors between them.ConclusionsThe influence of fatigue driving on injury severity is significantly underestimated if the endogeneity of fatigue driving on fatal injury propensity is ignored. Factors such as vehicle insurance and road types not only affect fatal injury propensity, but also fatigue driving propensity.Practical applicationsThe findings in this study can help better understand how those factors affect fatigue driving and injury severity, and contributes to more efficient policy for preventing the harmfulness of fatigue-related crashes.

Exploring relationships between microscopic kinetic parameters of tires under normal driving conditions,road characteristics and accident types

IntroductionFreeway accidents are a leading cause of death in China, which also triggers substantial economic loss and an emotional burden to society. However, the internal mechanism of how microscopic kinetic parameters of vehicles influenced by road characteristics determine the occurrence of different types of accidents has not been explicitly studied. This research aimed to explore the “link role” of tire microscopic kinetic parameters in road characteristic variables and traffic accidents to aid in facilitating the traffic design and management, and thus to prevent traffic accident. Method: A mountain freeway in Zhejiang Province, China was used as the research object and the data used in this paper were obtained through a real-time vehicle experiment. Multiple estimation models, including the standard ordered logit (SOL) model, fixed parameters logit (FPL) model, and random parameters logit (RPL) model were established. Results: The findings show that road characteristics will affect the longitudinal kinetic characteristics of the vehicle and, consequently, map the level of risk of rear-end accidents. Driving compensation effects were also identified in this paper (i.e., the drivers tend to be more cautious in complicated driving circumstances). Another finding relating to the mountain freeway is that different tunnel characteristics (e.g., tunnel entrance and tunnel exit) have different effects on different types of traffic accidents. Practical Applications: The framework proposed in this article can provide new insight for researchers to enlarge the research subjects of both explanatory and outcome variables in accident analysis. Future research could be implemented to consider more driving conditions.

The impact of intersection design on simulated driving performance of young and senior adults

PURPOSE: The Federal Highway Administration (FHWA) proposed guidelines for highway design to increase the safe driving ability of older drivers; however, little empirical evidence exists to support the effectiveness of these guidelines. The purpose of this study was to investigate the effects of implementing these guidelines (in 4 pairs of intersections) on safe driving performance of older and younger drivers using a high-fidelity driving simulator. DESIGN AND METHODS: We replicated four intersection pairs (improved versus unimproved) in a high-fidelity, virtual reality driving simulator. Simulator scenarios were created from actual road locations, replicating road geometrics and traffic control devices. The simulator's controls were integrated with an actual vehicle to make the driving experience as realistic as possible. Kinematic measures were obtained from the simulator in conjunction with driving errors recorded by trained driving evaluators sitting in the cab of the car. Thirty-nine subjects, 19 younger and 20 older adults, participated in the study. RESULTS: For the kinematic data we found greater lateral control, as indicated by significantly smaller maximum yaw during the turn phase, at all of the improved intersections when compared to the unimproved intersections. We found some significant age differences, but mostly in only one of the intersection-pairs. For the behavioral data, there were significant differences in driving errors between improved and unimproved intersections in two intersection-pairs; however, there were no significant differences in driving errors between the older and younger drivers. IMPLICATIONS: The findings suggest that both young and older drivers may benefit from roadways with safety features recommended by the FHWA guidelines as indicated by the increased lateral control of the vehicle when negotiating these intersections. These findings generate critical information for those involved in the design of roadway systems.
