Abstract : The effect of random driver reaction time on throughput at a saturated signalized intersection is studied. The model assumes zero acceleration time and identical terminal velocities for all vehicles. Analytic expressions are derived for the average number of vehicles that pass through the intersection during a go-period. Some calculations and curves are given for the specific case of a general gamma distribution function for the reaction time variable. It is shown that a mean value model is quite accurate for mean value purposes, but that variability in reaction time does cause significant variance in throughput. (Author)
