Abstract: This paper analyzes the characteristics of right turn driving at intersections using an alignment an asymmetric fundamental curve-available to right turn driving as right turn traffic lane, and then explores a new geometric design mcthcxl for ritht turn traffic lane which is called "dignnient melhvxl", this article also discusses the selection of and calculation on alignment geometric parameters. and provides ways and examples of applicalions of the new design method.

Key words: intersections, asymmetric, alignment, traffic lane, geometric parameters, right turn driving

摘要： 本文从分析交叉口右转车行驶特征出发,采用一种适宜右转车行驶的线形——非对称基本曲线作为右转车道线形,以此为依据探索出一种右转车道几何设计新法——线形法.文章还对线形几何参数的选择和计算进行了研讨,并提出了实施的方法和实例.
