针对我国现有道路交通条件下典型的信号控制交叉口，对不同车道宽度、转弯半径的右转车道的饱和车头时距进行现场测定。

Saturation time headways with different lane widths and turning radiuses were measured on the spot and abnormal data were identified and eliminated.

考虑右转车道宽度、转弯半径的影响，给出了右转车道饱和流量的回归计算模型。

A mathematical regression model on right-turning saturation flow was then established with the effect of lane width and turning radius being taken into.
