以新建小间距互通式立交区域主线范围内的交通状况为研究对象，运用交通冲突技术理论及VISSIM交通流微观仿真技术获取小间距互通式立交冲突率和间距关系模型，以小间距互通式立交区域的冲突率作为安全评价指标，运用灰色聚类理论，提出小间距互通式立交区域交通安全评价方法，把不同立交间距对应的安全等级分为四种类：不安全（D级），临界安全（C级），较安全（B级），安全（A级），对两个互通式立交间距小于700m的情况，应提出相应交通安全改善措施．应用结果表明：不同间距安全等级不相同，通过采用改善措施提高小间距互通式立交区域的安全状况，同时为新建小间距互通式立交区域安全评价提供有效途径．

Taking the traffic situation in the area of new small spacing interchange as a research object, it used traffic conflict technique and VISSIM traffic flow simulation technique to establish traffic conflict simulation and to obtain the small spacing interchange collision rate and spacing relational model; conflict ratio was taken as the safety assessment index in the small spacing interchange by means of gray cluster theory. According to the level of security in the small spacing interchange area, the paper divides into four types by the diffident spacing： unsafe （D-level）, criticality safety （C-level）, safer （B-level）, security （A-level）, and the two interchange spacing of less than 700m should be put forward corresponding measures to improve the traffic safety. Application results show that： Interchange of different spacing is not the same level of security, the use of improved measures can improve the safety situation of small spacing interchange area. At the same time, it provides effective safety evaluation of interchange for the new small spacing area.
