IAP Project: Use of SHRP2 NDS Data to Evaluate Roadway Departure Characteristics

ISU: This research was sponsored by Federal Highway Administration Implementation Assistance Program. The purpose of this effort is to support the use of various components of the SHRP2 Naturalistic Driving Study database by personnel from CTRE/ISU. The main objective of this project is to identify factors contributing to roadway departure crashes/near crashes and develop a proof of concept to evaluate road departure risk for two to three roadway types. The study will look at driver, environmental, roadway, and vehicle factors that contribute to roadway crashes and near crashes. The project will also evaluate driver behavior on curves. The dataset delivered for this AASHTO Implementation Assistance Program project consisted of a sample of detailed event tables (including trip summaries, vehicle, and driver survey results) ), forward video, and time series variables for 1734 crash-related events and 4665 baseline events from the SHRP2 NDS.ISU：本研究由美国联邦公路管理局（Federal Highway Administration）实施援助项目资助。本工作旨在支持CTRE/ISU相关人员调用战略公路研究计划2（Strategic Highway Research Program 2, SHRP2）自然驾驶研究（Naturalistic Driving Study, NDS）数据库的各类组件。本项目的核心目标为识别引发车道偏离碰撞与接近碰撞险情的影响因素，并开发概念验证方案，以评估2至3类道路类型的车道偏离风险。本研究将分析与道路碰撞及接近碰撞险情相关的驾驶员、环境、道路与车辆四类影响因素。此外，本项目还将评估弯道区域的驾驶员行为。本次为美国国家公路与运输协会（American Association of State Highway and Transportation Officials, AASHTO）实施援助项目交付的数据集，包含来自SHRP2 NDS的1734起碰撞相关事件与4665起基准事件的详细事件表（涵盖行程摘要、车辆及驾驶员调查结果）、前置式视频与时序变量数据。
