摘　　要：针对无信号畸形交叉口有别于规则交叉口的几何特性,以及因几何特性的不同而带来的安全问题,通过分析驾驶员在畸形交叉口处观察相交道路车辆情况的过程与特点,利用多自由度驾驶仿真平台,对驾驶员在畸形交叉口的驾驶操作及视认特性进行实验,并根据实验所得数据,提出基于驾驶员视认性的畸形交叉口安全视距计算方法,从而得到基于驾驶员视认性的畸形交叉口视距的计算,并对畸形交叉口平面设计进行建议改善,以满足安全通行的需求。Aiming at the safety problems caused by the geometric properties difference between the skewed intersection without signals and the normal intersection, the paper analyzes the process and characteristics of the drivers＇ observation about the traffic in skewed intersection. The multiple degree-of-freedom driving simulation platforms are used to conduct an experiment about the drivers＇ driving operation and observation features in the skewed intersection. Based on the data from the experiment and the drivers＇ observation features, a safety sight distance calculation method that can be used in the skewed intersection is presented. Then, the advice is given on the skewed intersection design to meet the safety requirements.
