Secondary Analyses and Archive of Naturalistic Driving Data in Aging and Dementia

描述（由申请人提供）：该项目的总体目标是创建一个可公开访问的自然驾驶数据库，使用新颖的方法来识别不安全驾驶事件，期望这种方法也可以适用于更广泛的临床和实验使用。该项目将利用从之前两个项目中获得的丰富知识和经验，这些项目研究了正常衰老和痴呆症的真实驾驶情况，其中一个项目在3年的纵向研究中采用了一系列道路测试，另一个项目使用车载摄像机对驾驶员进行了一年的自然记录研究。我们将使用第二项研究（N=103）， NIA 2R01 #AG016335，“认知障碍老年人驾驶的自然评估”的大量基线和一年随访数字视频收集，该研究无法完全手工审查。数据将使用新的和高度创新的计算机分析车道偏离和接近脱险事件的方法重新分析，然后通过安全评级方法进行评分。该研究项目还将包括对老年驾驶员自然驾驶数据的二次分析

DESCRIPTION (provided by applicant): The broad goal of this project is to create a publicly accessible naturalistic driving database, using novel methods to identify unsafe driving events, with the expectation that this methodology could also be adapted for more widespread clinical and experimental use. This project will leverage the wealth of knowledge and experience that has been gained from two previous projects examining real-world driving in normal aging and dementia, one employing serial road tests in a 3-year longitudinal study, the other involving naturalistic recordings of drivers with in-car video cameras studied over one year. We will use the large volume of baseline and one-year follow up digital video collection of naturalistic drivin from the second study (N=103), NIA 2R01 #AG016335, "Naturalistic assessment of driving in cognitively impaired elders," which could not be manually reviewed completely. The data will be re-analyzed in totality using new and highly innovative methods of computerized analysis of lane deviation and near miss events, and then scored by safety rating methods. This research project will also include secondary analyses of naturalistic driving data on older drivers with and without cognitive impairment comparing naturalistic driving to prior history of motor vehicle accidents and road test scores. The resulting bookmarked video and tabular data, including demographic, road test, and cognitive test information, will be a valuable naturalistic driving resource that will be archived and disseminated for other researchers to use in their own studies of older drivers. We will disseminate the archived naturalistic data through the National Archive of Computerized Data on Aging (NACDA) as well as notify the public of data availability on the research teams' websites and publications of secondary analyses. By proper and thorough de-identification of the video recordings, this data archive will facilitate the use of data that woul otherwise not be available due to the difficulty in obtaining such data as well as the sensitive nature of the data obtained.
