电力突发事件应急管理中的博弈

电力安全一直是人们关注的问题,电力系统对无法预料的灾难性突发事件表现的非常脆弱,电力突发事件的应急管理对维护电力系统安全运行具有十分重要的意义。电力突发事件的状态是在不断变化的,应急管理人员必须根据电力突发事件发展趋势动态地调整管理活动。本文分析了突发事件应急管理中＂电力突发事件＂与＂应急管理者＂之间的动态博弈过程,＂应急管理者＂会随着＂电力突发事件＂的动态演变,不断调整其管理方法,控制住＂电力突发事件＂。通过分析＂电力突发事件＂与＂应急管理者＂之间的博弈,构建了电力突发事件有效应急管理程序。＂应急管理人员＂以动态博弈的思想处理＂电力突发事件＂,结果表明该方法能更好的发挥应急处理预案的作用,更有效的处置＂电力突发事件＂。     

一起苯乙烯槽罐车泄漏的应急监测案例

2007年10月28日凌晨，镇江市环境监测中心站于3：40接到市环保局应急指挥中心关于338省道200km处，发生一起苯乙烯槽罐车泄露的紧急交通事故通知，于是立即启动应急监测响应程序，监测站应急监测小组于4：20到达事故现场，并立即用快速检测装备进行现场定性、定量跟踪监测，及时向现场应急指挥部提供了第一线的监测数据，为污染事故的及时控制与安全处置提供了决策依据。经13个多小时的共同处置，罐内苯乙烯得到安全驳载，肇事车辆被拖离现场，交通也顺利恢复。

化工园区突发环境事件应急预案编制的研究

我国的化工园区为促进经济和社会发展做出了重要贡献。由于化工园区内危险化学品种类多、有毒有害物质数量大、环境风险等级高,存在着发生重特大事故的现实性和可能性。但是,我国至今尚未制定化工园区突发环境事件应急预案编制技术规范,相关研究也未见报道。在当前化工园区安全生产事件高发并严重影响周边环境的情况下,研究化工园区突发环境事件应急预案编制方法,提高应对安全生产事故以及次生突发环境事件的能力尤为重要。通过分析化工园区环境风险物质、环境风险工艺和环境风险受体三个方面的环境风险的特性,初步拟定了化工园区突发环境事件应急预案编制调查评估、建章立制、预案编写三个阶段的技术路线,明确了开展环境风险评估、加强应急能力建设、完善环境风险防范措施和环境应急处置措施的四项编制要点,在此基础上提出了化工园区突发环境事件应急预案由综合预案、现场处置预案、专项预案、环境风险评估报告、环境应急资源调查报告六部分组成的结构框架。

Autonomous emergency braking systems adapted to snowy road conditions improve drivers' perceived safety and trust

Objective: This study investigated drivers' evaluation of a conventional autonomous emergency braking (AEB) system on high and reduced tire–road friction and compared these results to those of an AEB system adaptive to the reduced tire–road friction by earlier braking. Current automated systems such as the AEB do not adapt the vehicle control strategy to the road friction; for example, on snowy roads. Because winter precipitation is associated with a 19% increase in traffic crashes and a 13% increase in injuries compared to dry conditions, the potential of conventional AEB to prevent collisions could be significantly improved by including friction in the control algorithm. Whereas adaption is not legally required for a conventional AEB system, higher automated functions will have to adapt to the current tire–road friction because human drivers will not be required to monitor the driving environment at all times. For automated driving functions to be used, high levels of perceived safety and trust of occupants have to be reached with new systems. The application case of an AEB is used to investigate drivers' evaluation depending on the road condition in order to gain knowledge for the design of future driving functions.

Methods: In a driving simulator, the conventional, nonadaptive AEB was evaluated on dry roads with high friction (μ = 1) and on snowy roads with reduced friction (μ = 0.3). In addition, an AEB system adapted to road friction was designed for this study and compared with the conventional AEB on snowy roads with reduced friction. Ninety-six drivers (48 males, 48 females) assigned to 5 age groups (20–29, 30–39, 40–49, 50–59, and 60–75 years) drove with AEB in the simulator. The drivers observed and evaluated the AEB's braking actions in response to an imminent rear-end collision at an intersection.

Results: The results show that drivers' safety and trust in the conventional AEB were significantly lower on snowy roads, and the nonadaptive autonomous braking strategy was considered less appropriate on snowy roads compared to dry roads. As expected, the adaptive AEB braking strategy was considered more appropriate for snowy roads than the nonadaptive strategy. In conditions of reduced friction, drivers' subjective safety and trust were significantly improved when driving with the adaptive AEB compared to the conventional AEB. Women felt less safe than men when AEB was braking. Differences between age groups were not of statistical significance.

Conclusions: Drivers notice the adaptation of the autonomous braking strategy on snowy roads with reduced friction. On snowy roads, they feel safer and trust the adaptive system more than the nonadaptive automation.     

Motorcycle crashes potentially preventable by three crash avoidance technologies on passenger vehicles

Objective: The objective of this study was to identify and quantify the motorcycle crash population that would be potential beneficiaries of 3 crash avoidance technologies recently available on passenger vehicles.

Methods: Two-vehicle crashes between a motorcycle and a passenger vehicle that occurred in the United States during 2011–2015 were classified by type, with consideration of the functionality of 3 classes of passenger vehicle crash avoidance technologies: frontal crash prevention, lane maintenance, and blind spot detection. Results were expressed as the percentage of crashes potentially preventable by each type of technology, based on all known types of 2-vehicle crashes and based on all crashes involving motorcycles.

Results: Frontal crash prevention had the largest potential to prevent 2-vehicle motorcycle crashes with passenger vehicles. The 3 technologies in sum had the potential to prevent 10% of fatal 2-vehicle crashes and 23% of police-reported crashes. However, because 2-vehicle crashes with a passenger vehicle represent fewer than half of all motorcycle crashes, these technologies represent a potential to avoid 4% of all fatal motorcycle crashes and 10% of all police-reported motorcycle crashes.

Discussion: Refining the ability of passenger vehicle crash avoidance systems to detect motorcycles represents an opportunity to improve motorcycle safety. Expanding the capabilities of these technologies represents an even greater opportunity. However, even fully realizing these opportunities can affect only a minority of motorcycle crashes and does not change the need for other motorcycle safety countermeasures such as helmets, universal helmet laws, and antilock braking systems.
