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.

基于层次灰色模型的铁路技术创新绩效综合评价

运用技术创新基本理论,结合铁路技术创新实际,从效益(经济、社会)增长、市场状态(市场份额、市场营销)改善和创新主体素质(技术装备水平、管理水平)提高3个方面建立了评价铁路技术创新绩效的多级指标体系。将层次分析法(AHP)和灰色系统理论结合起来建立了层次灰色评价模型(HGM),运用该模型对铁路技术创新绩效分别从整体和分项进行了综合评价,得出:铁路技术创新绩效绩优度为“一般”,其主要原因在于铁路运输市场状态改善中市场份额扩大程度较低。实证分析结果表明:改进层次灰色评价法(层次灰色评价模型)为一种评价铁路技术创新绩效的有效方法。     

Japanese perspective of driver information systems
