摘  要:基于八自由度的驾驶模拟器研究了地下道路车道宽度、车道位置、侧向净宽对驾驶行为的影响。受试者在一条单向三车道的地下道路场景中进行了试验。试验结果表明车道宽度和侧向净宽对车速、偏移及主观感知都有影响，而车道宽度的影响更为显著。不同车道上，驾驶行为表现出与驾驶人的主观感知不一致。基于横向偏移状态分析了不同条件下的行车安全性，并为地下道路设计车速、车道宽度、限速、车道组合等方面提出了建议。

Abstract: Based on 8-DOF (degree of freedom) drivingsimulator, the effects of lane width, lane position and lateral clearance ondriving behavior in urban underground road have been examined. Participantsdrove in a separating one-way three-lane of underground road with a drivingsimulation. Speed, lane deviation and subjective perception were collected. Theresult shows that lane width and lateral clearance have significant effects onobjective and subjective measures. The effect of lane width is greater than lateralclearance. An interesting finding is that the inconsistence of the drivingbehavior measures with subjective perception of the lane position. Thesefindings provided support for amending the current design specifications of urbanunderground road, such as relationship between design speed and lane width,speed limit, combination form of lanes.
