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.

基于对流效应的寒区路堤块石层临界高度研究

为了研究块石路堤降温效应与块石层高度之间的关系,基于多孔介质自然对流理论和热传导理论引入了表征寒区块石路堤自然对流降温效应的自然对流指数,利用热传导温度分布函数获得了路堤自然对流指数随块石层高度变化的近似公式。分析表明:自然对流指数最小值对应于路堤块石层的最小高度,而其最大值对应于路堤块石层的最大高度。另外介绍了一种利用自然对流指数近似公式估算路堤块石层临界高度的方法,并具体给出了算例,最后进行了数值验算。结果表明:通过自然对流指数确定的临界高度可为寒区工程的路堤设计提供参考。
