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
