驾驶辅助技术在事故预防中的应用效果

越来越多的车型都搭载了驾驶辅助系统,部分驾驶人对这类系统的实际效果持怀疑态度。本文通过调研国内外相关研究,对几类主流驾驶辅助系统的事故预防效果进行综述。与相同条件下未安装驾驶辅助系统的车辆对比,研究人员发现多数驾驶辅助系统在事故预防方面发挥了明显的作用,降低了相关的事故率、保险索赔率,其中前向和后向的自动紧急制动系统效果最为显著。此外,驾驶人对驾驶辅助系统的接受度以及响应度均会影响事故预防效果。

河流突发性污染事故风险评价方法的探讨

通过危险源和环境因素两个方面进行河流突发性污染事故风险评价,引入加权危险河段长度和河段危害权重两个概念论述危险源风险评价,给出能够反映各河段重要性的新的危险源风险评价方法。评价了流速、降水、地形等自然环境因素对突发性水污染事故发展的影响,提出了环境因素定性评价方法。     

重视道路因素对道路交通安全的影响

对道路交通系统的客观分析后发现,在以往事故分析中对人、车、路三因素间的关系分析不足。针对此问题,对道路事故处理中过多偏重驾驶员因素进行了原因分析,然后通过计算分析指出道路因素应占有更大的比例,在未来道路交通安全分析中应该重视道路因素的影响。     

水上交通事故致因理论探讨

在对比国际上有代表性的事故致因理论的基础上提出水上交通事故致因理论,认为水上交通事故的本质原因在于水上交通安全管理体系的缺陷,并通过案例进行验证。     

略论校园事故民事责任

未成年学生在校伤亡事故时有发生,该类事件发生后,往往引起学生家长方与学校方之间的纠纷。对于校园事故民事责任的认定、承担等法律问题,教育界、法律界人士也各自提出了不同的意见。现有法律如《民法通则》、《人身损害赔偿意见》、《学生伤害事故处理办法》等规定亦不完全一致。本文拟对校园事故民事责任的有关法律问题作一初步探讨。     

A list of accident scenarios for three legs skewed intersections

The term ‘scenario’ is used in the safety field to designate a prototype or a model of an accident process characterised by chains of facts, actions, causal relations and consequences in terms of damage to people and property. The prototypical scenarios, properly realized, provide a basis on which to consider the action to be taken, but also a concrete backup for accident information for use in information campaigns or training. The objective of this study is to define the prototypical accident scenarios for a particular configuration of road intersection: the skewed intersection. Limited sight distance at skewed intersections leads to safety issues. A non-skewed intersection provides the best operating conditions as drivers can easily sense the direction in which they are travelling, estimate the speeds of the opposing traffic and smoothly complete a maneuver in shorter time. In skewed intersections, instead, the ability of drivers to recognize any conflicting vehicles diminishes in comparison to right-angle intersections. The logical-deductive approach used in this paper for the determination of accident scenarios is based on an analysis of a large database of incidents, which occurred on several roads in eastern Sicily on 35 skewed intersections at three-legs. The skew angle of the minor leg of all the intersections studied is between 15° and 20°. This research allowed to develop accident scenarios related to particular configurations of intersections, compatible with the Italian rules. Prototypical scenarios are constructed using samples of accidents occurring on a particular type of study area, especially when they are based on files from in-depth investigations. The method used is an inductive approach, based on an examination of each case, grouping together similar cases and building a prototypical scenario using this case grouping. From the in-depth analysis of database accidents 9 prototypical accident scenarios have been identified for the skewed intersections.
