【摘要】：针对山区双车道公路交叉口视距不良现象,通过分析驾驶员在交叉口的识认性特性,研究了山区双车道公路交叉口行车过程较平原区公路交叉口驾驶员增加转动头部或身体的时间过程。采用Smart eye 5.7眼动仪对驾驶员通过山区双车道公路交叉口的识认性进行实车试验,并根据驾驶员的注视时间(包括眨眼、扫视和注视时间)和山区公路交叉口几何数据(包括交叉角度和支路坡度),分别建立了基于驾驶员视认性的无控交叉口和停让交叉口停车视距计算模型,并根据所建模型计算了山区双车道公路交叉口停车视距及其建议值,为山区公路交叉口的设计提供理论依据。
[Abstract]:In view of the phenomenon of poor visual distance at the intersection of two-lane highway in mountainous area, the recognition characteristics of the driver at the intersection are analyzed.In this paper, the time course of turning the head or body of the drivers at the two lane road intersections in mountainous area is studied, which is more than that in the plain area.Using Smart eye 5.7 eye movement instrument, the recognition of drivers passing through the mountain area two-lane highway intersection was tested, and according to the driver's gaze time (including blinking),The geometric data of mountain road intersection (including intersection angle and branch slope) and the time of scan and fixation are used to establish the model of sight distance calculation of uncontrolled intersections and stop / stop intersections, respectively, based on the recognition of drivers.Based on the established model, the parking sight distance and its recommended value at the two lane road intersection in mountainous area are calculated, which provides the theoretical basis for the design of the mountain road intersection.
