中文摘要
      为验证驾驶模拟技术在跟驰行为研究中的有效性,设计了实车实验与驾驶模拟实验。选取了跟驰距离、跟驰距离标准差、车头时距及驾驶员反应延迟时间作为分析指标,并采用Wilcox检验、生存分析方法分别验证了非时间数据、时间数据的有效性。结果表明跟驰距离、车头时距、驾驶员反应延迟时间具备绝对有效性,两种不同实验环境下跟驰距离标准差随跟驰速度变化趋势相同,具备相对有效性。实车实验中,前车加速度、前后车相对距离、前车加速度变化状态显著影响驾驶员反应延迟时间。有效性分析结果为基于驾驶模拟实验的跟驰行为研究提供前提条件,生存分析结果可用于驾驶员反应延迟时间建模及跟驰模型优化。
英文摘要
      In order to verify the validation of car-following behavior study based on driving simulation, the natural driving experiment and driving simulation experiment were designed. The driver’s delay time, car-following distance and its standard deviation were selected as analysis index. The validity of non-time data and time data were verified by Wilcox test and survival analysis method respectively. The result indicates that car-following distance and driver’s delay time have absolute validity. The standard deviation of car-following distance has the same change trend in two different experimental environments, which means it has relative validity. In the natural driving experiment acceleration of the following vehicle, relative distance, and acceleration change status of the following vehicle effect driver’s delay time significantly. The result of validation study provides precondition for other driving-simulation-based car-following behavior research. Survival analysis result can be used for driver’s delay time modeling and car-following model optimization.
