摘要： 为了验证驾驶模拟技术应用于高速公路改扩建期间施工路段强制变道行为分析的有效性，开展了实车驾驶和驾驶模拟2种实验。首先，采集车辆的速度和位置信息，计算了强制变道的断面车速v、特征断面间距Δd和特征断面时距Δt等行为指标；然后，分别采用非参数统计方法与回归模型来检验各行为指标的绝对有效性与相对有效性。结果表明：驾驶模拟技术能有效地应用于高速公路改扩建期间强制变道行为分析；变道开始断面的车速、越线点与施工路段起点之间的间距和时距、变道结束点与施工路段起点之间的间距和时距均显示出驾驶人在驾驶模拟环境中具有更激进的驾驶行为。

Abstract: In order to verify the validity of the driving simulation technology in the analysis of mandatory lane-changing behavior during highway reconstruction and expansion period, two kinds of experiments, field experiment and driving simulation, were carried out. Firstly, the speed and position information of vehicles were collected, and the behavior indexes such as the spot speed v, spot spacing Δd, and headway Δt were calculated; and then, non-parametric statistical testing method and regression model method were used to test the absolute and relative validity of each behavior index respectively. The results show that the driving simulation technology can be validly applied to analyze the mandatory lane-changing behavior in highway reconstruction and expansion period. The spot speed at the start of the mandatory lane-changing, the spot spacing and headway between the line-crossing spot and the beginning of construction section, and the spot spacing and headway between the end spot of lane-changing and the beginning of construction section show that drivers have more aggressive driving behaviors in driving simulation environment.

Key words: traffic engineering; highway reconstruction and expansion; mandatory lane-changing; driving simulation
