Effect of Cross-sectional Design on Driving Behavior in Urban Underground Road

Abstract:

Based on 8-DOF driving simulator, the effects of lane width, lane position and shoulder width on driving behavior in urban underground road have been examined. Participants drove in a separating one-way three-lane of underground road with a driving simulation. Speed, lane deviation and subjective perception were collected. The result shows that lane and shoulder width have significant effects on objective and subjective measures. The effect of lane width is greater than shoulder width. An interesting finding is that the inconsistence of the driving behavior measures with subjective perception of the lane position. These findings provided support for amending the current design specifications of urban underground road, such as relationship between design speed and lane width, speed limit, combination form of lanes.
