Road Safety Engineering and Senior Drivers

虽然人们对驾驶私人机动车的老年司机表现不佳的问题引起了很大关注，但对他们在牵引车、公共交通巴士(城市和城际)和校车等与商业车辆相关的较高工作量的环境中的安全经验了解很少。驾驶任务的复杂性增加，加上无法自我调节(例如，避开交通高峰期、恶劣天气和夜间时间)，这在私家车高级司机中很常见。一个特别令人担忧的问题是，加拿大大多数司法管辖区最近取消了针对校车司机的强制退休政策。现在，所有商业司机都可以在65岁的传统退休年龄后继续工作。这项研究将按年龄组检查不同类别商业司机的安全表现，试图量化较年长年龄组的安全表现可能恶化的程度。这些结果将有利于支持针对高级司机持续就业的政策和/或对策。

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.
