摘　　要：城市道路平面交叉口规模由相交道路红线切角决定,交叉口红线切角值大小应满足视距三角形的要求。在对安全停车视距和视距三角形计算原理进行建模分析的基础上,提出一种对交叉口4个方位红线切角值统一处理的方法。并结合成都市不同红线宽度道路横断面组成和设计车速,对相同红线宽度和不同红线宽度道路相交的平面交叉口红线切角值的取值方法及过程进行详细论证,最终得到道路平面交叉口最小红线切角值。The scale of urban road intersection is determined by the boundary line cutting angle value of the crossing roads, and the size of boundary line cutting should meet the requirements of stopping sight triangle. Based on the analysis of the calculation model of the stopping sight distance and sight triangle, this paper comes up with a solution to the boundary line cutting angle value of intersection from the four directions. Combining with the formation and design speed of the road intersection with the different boundary line width, it verifies the value-taking method and process in the intersection of crossing roads with the same boundary line width and different boundary line width and finally obtains the minimum cutting angle value of the boundary line of the road intersection.
