中文摘要：

选取一段频繁发生车流减速波现象的城市快速路作为数据采集地点，结合视频检测技术进行微观减速波数据采集与处理。基于减速波传播过程中车辆速度和加速度的数据分析，得出驾驶员在波传播过程中的微观行为特征，在此基础上给出减速波传播过程中驾驶员反应过程的具体描述，分为感知阶段、决策阶段和控制阶段；进一步从驾驶员感知时间、减速波传播速度和传播图像3方面对减速波传播特性进行研究，可为减速波微观仿真与控制提供一定的理论基础。

英文摘要：

A section of Beijing urban expressway is selected for data collection, on which deceleration shockwaves frequently occur during rush hours, and video detection technique is also utilized for deceleration shockwave data acquisition. Microscopic driver behavior during deceleration shockwave propa-gation are studied based on data analysis, and a description of driver＇s reaction process including perception, decision and control is proposed for describing deceleration shockwave propagation. Moreover, driver＇s perception time, shockwave propagation velocity and propagation image are detailed studied, which can be theoretical foundations for further deceleration shockwave microscopic simulation and control.
