Road Safety Engineering and Senior Drivers

虽然有很多人关注老年驾驶员驾驶私人机动车的表现不佳，但很少有人了解他们在涉及与商用车辆相关的更高工作量的环境中的安全经验，如拖拉机拖车，公交车（城市和城际）和校车。驾驶任务的复杂性增加，加上无法自我调节（例如，避免在交通繁忙时间、恶劣天气及夜间行车），这是私家车资深司机的常见做法。一个特别令人关切的问题是，最近加拿大大多数司法管辖区取消了针对校车司机的强制性退休政策。现在，所有商业司机都可以在65岁的传统退休年龄之后继续工作。这项研究会按年龄组别研究不同类别的商用车司机的安全表现，以量化较年长组别的司机在安全表现方面的假设恶化程度。这些结果将有利于支持政策和/或对策，针对正在进行的就业的高级驾驶员。

While there has been much attention directed to the under-performance of older drivers operating private motor vehicles, little is understood regarding their safety experience in settings that involve higher workloads associated with commercial vehicles such as tractor-trailers, transit buses (urban and inter-city), and school buses. Increased complexity of the driving task is compounded with an inability to self-regulate (e.g., avoid peak traffic periods, inclement weather and night-time hours) which is common among senior drivers of private vehicles. A particular concern has been the recent abolition of mandatory retirement policies in most Canadian jurisdictions that were directed toward school bus drivers. It is now possible for all commercial drivers to continue working beyond the traditional retirement age of 65 years. This study will examine the safety performance of different categories of commercial drivers by age cohort in an attempt to quantify the presumed deterioration of safety performance among the older age groups. These results will be beneficial to support policies and/or countermeasures that target the on-going employment of senior drivers.
