对TRANPLAN,CUBE和TransCAD的技术分析比较——以南加州尔湾市为例

TransCAD和CUBE是美国今后替代TRANPLAN的两个主要交通模型软件。TransCAD和CUBE均具有较强的模型和地理信息系统功能,两者各有所长。今后南加州区县交通模型要从TRANPLAN逐步过渡到TransCAD,但是包括佛罗里达和亚特兰大在内的美国许多其他地区选择使用CUBE,说明两个软件均占有各自的市场并受到欢迎。南加州尔湾市交通模型软件评估实例显示,对模型软件的评价和选择不仅要比较软件本身的特点,而且要对当地的模型政策、模型的功能要求。周围的模型环境。与数据结构和计算机网络系统的相容性等多方面进行综合的考量,采用多方面的评价标准审慎进行。

着陆阶段航空器航迹检测与风险识别方法

进近着陆是整个飞行过程中最易发生危险的阶段.目前着陆阶段的风险识别 只能依靠塔台管制员的目视观察.在飞行员技术不熟练、起降频繁的通用航空飞行训练 中,目视观察很难准确掌握情况,也因此蕴含了巨大的安全风险.利用视频监视航空器着 陆行为,同时提出了一种适合复杂背景下小目标分割算法,从视频中提取航空器着陆航 迹;并以此为基础进一步识别降落过程中的运行风险.通过对多组不同角度的视频监视数 据验证,该算法可在复杂背景下实现航空器着陆航迹的跟踪、落地时刻的判断及危险滑 行航迹的准确识别,对于保障飞行安全具有重要的现实意义.

Do driver training programs reduce crashes and traffic violations? — A critical examination of the literature

This paper reviews the evaluation literature on the effectiveness of classroom and behind-the-wheel driver training. The primary focus is on North America programs as originally taught in high schools but now also by private instructors. Studies from the United Kingdom, Australia, New Zealand and Scandinavia are also included.By far the most rigorous study to date was the experimental study in DeKalb, Georgia, U.S.A. This study used a randomized design including a control group and a very large sample size to provide reasonable statistical precision. I reexamine the DeKalb data in detail and conclude that the study did show evidence of small short-term crash and violation reductions per licensed driver. However, when the accelerated licensure caused by the training is allowed to influence the crash and violation counts, there is evidence of a net increase in crashes.The other studies reviewed present a mixed picture but the better designed quasi-experimental evaluations usually showed no effects on crash rates but almost all suffer from inadequate sample size. I show that as many as 35,000 drivers would be required in a two group design to reliably detect a 10% reduction in crash rates.The advent of GDL laws in North America and other countries has largely remedied the concern over accelerated licensure of high risk teenage drivers by delaying the progress to full licensure. Conventional driver training programs in the U.S. (30 h classroom and 6 h on-the-road) probably reduce per licensed driver crash rates by as little as 5% over the first 6-12 months of driving. The possibility of an effect closer to 0 cannot be dismissed.Some GDLs contain an incentive for applicants to complete an advanced driver training program in return for shortening the provisional period of the GDL. The results of Canadian studies indicate that any effects of the driver training component are not sufficient to offset the increase in accidents due to increased exposure.There is no evidence or reason to believe that merely lengthening the number of hours on the road will increase effectiveness. Programs directed toward attitude change and risk taking better address the underlying cause of the elevated crash risk of young drivers but these behaviors are notoriously resistant to modification in young people.
