气象信息在船舶管理中的应用

从船舶航行安全、可靠性角度考虑，一个重要的影响因素是航行船舶所在海域的气象状况，因此气象信息对于船舶调度管理起到非常积极重要的作用。如何获取气象信息，并把获取的气象信息融合到电子海图显示平台中，对于航行船舶的监控和管理显得十分有意义。针对如何获取气象信息及如何与电子海图叠加显示两方面的内容进行了论述。     

Young drivers and graduated licensing: The Ontario case

Despite improvements in road safety over the past several decades, accident rates remain high for young drivers. One accident countermeasure that is expected to improve the safety record of this group is graduated licensing. The philosophy behind this licensing system is that novice drivers, of whom the majority are young, should be restricted to relatively safe driving environments during the initial learning period. Graduated licensing was implemented in the Province of Ontario, Canada in 1994. The objective of this study is to estimate the potential benefits and costs for young drivers associated with two components of the Ontario graduated licensing package: the late-night driving curfew and the high-speed roadway restrictions. Based on accident and travel data for the year 1988, accident-involvement rates per kilometre driven were calculated for different driver groups for various combinations of time of day and roadway speed limit. These rates were then applied to the expected mobility profiles of young drivers affected by graduated licensing. The results of the study support the late-night curfew and suggest that this component of the licensing package should reduce total accident involvements for the affected group by up to 10 percent and fatal accident involvements by up to 24 percent, while reducing their total driving by only four percent. By contrast, the empirical evidence suggest that the high-speed roadway restrictions are likely to increase accident involvements, and thus it is strongly recommended that this component of Ontario's graduated licensing package be changed.     

Mobile phone use while driving: public opinions on restrictions

This paper reviews two road-user surveys on the use of mobile phones on the road in Finland where the mobile phone ownership rate is highest in the world (70% in August 2000). From 1998 to 1999 the proportion of drivers that chose to use a mobile phone while driving rose from 56% to 68%, while the proportion of phone using drivers who experienced dangerous situations due to phone use rose from 44% to 50%. The proportion of drivers who used their phones in some way to benefit safety on the road remained at about 55%. The youngest, novice drivers had the highest level of phone usage of all age categories. Over 48% of the interviewees believed that the government should ban the use of hand-held mobile phones while driving, and another 27% believed that all types of mobile phone use should be banned while driving. Those drivers who used their phones the most each day were more likely to want some form of restrictions, than those who had lower usage. This is a strong message to the elected lawmakers and raises the problem of exactly how regulatory bodies would go about controlling the future growth of new driver support and non-driving related communication devices in road vehicles. It was concluded that legislating for hands-free use only would be a reasonable course of action. Mandating that the current generation of equipment should be optimized for hands-free use should result in future generations of in-vehicle equipment also being optimized for hands-free use as a minimum criterion.

笔者从中国现代道路交通系统的发展现状与道路交通安全状况出发，以过去10多年中国汽车、摩托车保有量的发展轨迹为基础，对中国未来一定时期（2004～2015年）机动车保有量的发展变化及政府采取不同管理对策条件下的道路交通安全状况的发展水平进行了预测。结果表明：政府管理对策对道路交通安全状况变化具有决定性影响。     

交通环境对交通安全的影响及对策

交通安全涉及人、车、道路及环境等诸多因素,对交通事故的成因分析表明,驾驶员的责任是主要影响因素,其次是车辆和道路因素。但不容忽视的是,目前关于交通环境对事故影响的研究尚不够充分;交通管理部门确定事故原因也主要从人、车2 因素入手,较少涉及交通环境因素。事实上,作为事故的间接原因,交通环境常常通过间接作用影响安全,亦即不良的交通环境诱发人的不安全行为,从而导致人员违章等交通事故的发生。
