Abstract: Various simulation programs and optimization techniques have evolvedthat aid the traffic engineer in the optimization process. None of theoptimization programs consider the day to- day stochastic variability in thedelay during the optimization process. The purpose of this paper is toestimate variability in delay at signalized intersections and incorporatethe variability in the optimization process. An analytical methodology tocompute the variance of delay for an isolated intersection and arterialintersections is developed. In this paper delay variance is computed for anisolated intersection using expectation function method for under-saturatedconditions.

Keywords: Stochastic optimization, genetic algorithms (GA), variability, highway capacity manual (HCM), timing plan, level of service (LOS)
