Influence of Stopped Delay on Driver Gap Acceptance Behavior

The influence of stopped delay on driver gap acceptance behavior is investigated for minor road drivers executing left‐turning maneuvers. The mean critical gap ($\overline{c}$) and its variance $\left({\sigma }^2\right)$ are separately estimated for the aggregated data and abstractions of the data based on the duration of stopped delay. It has been found that for mean stopped delays shorter than 25 s the mean critical gaps are higher than the value obtained from the aggregated data, while for mean delay in excess of 30 s, it is lower. The practical significance of these differences in mean critical gaps as reflected in the computed values of the minor road capacity is then speculated upon.
