Influence of Stopped Delay on Driver Gap Acceptance Behavior

Abstract

A study is reported which estimates gap acceptance parameters for different groups of drivers who experienced varying durations of stopped delay and compares it with parameters estimated from aggregated data. The study statistically compared the mean critical gaps obtained from the disaggregated data with that obtained from the aggregated data. The investigation also speculated on the likely implications on the computed minor road capacity arising from differences in the estimated mean critical gaps for each duration of delay as compared with the value from aggregated data. The study results support the hypothesis that the duration of stopped delay experienced by minor road drivers while assessing gaps in the main traffic stream influences their gap acceptance behavior.
