| 摘 要： | 间隙接受理论是计算公路无信号交叉口通行能力的主要方法之一，临界间隙和随车时距是其中２个重要参数，交叉口的不同几何构成，不同的车辆组万能主车流量大小，都影响着临界间隙值的大小，在我国首路交通条件下，确定具有代表性的公路交叉口临界间隙和随车时距值。具有重要意义。本文通过对不同地区无信号交叉口大量的交通观测，应用Ａｓｈｗｏｒｔｈ方法计算得出我国各地区的临界间隙与随车时距值。这对交叉口通行能力计算提供了重

| Abstract: | Gap acceptance theory is one of calculating the capacity method of unsignalized intersections. Both Critical gap and follow up time play great role in that method. These two parameters depend upon geometric conditions of unsignalized intersections, vehicle types and traffic volume. It is very importation for our country to determine the critical gap and follow up time value at unsignalized intersections in China typical region under the current road and traffic conditions. This paper applied the Ashworth method determined the critical gap and follow up time for different regions by a great deal traffic investigation. These parameters are basis for calculating the capacity of unsignalized intersections. |
