ABSTRACT
This paper describes a bicriterion equilibrium traffic assignment model that accurately fore- casts path chokes and consequent total arc flows for a stochastically diverse set of trips. Called T2, its develops around a linear generalized cost model, which generalizes classical traffic assignment by relaxing the value-of-time parameter from a constant to a random variable with an arbitrary probability distribution. For the case where arc time and/or cost are flow dependent, this paper formulates conditions and algorithms [or stochastic bicriterion user-optimal equilibrium arc flows, which reflect every trip's exclusive use of a path that minimizes its particular perception of generalized cost.

    In this note, we give estimates of small deviation probabilities of the sum ∑j≥1 λj Xj, where {λj} are nonnegative numbers and {Xj} are i.i.d. positive random variables that satisfy mild assumptions at zero and infinity. Bibliography: 10 titles.

    Ranked set sampling can provide an efficient basis for estimating parameters of environmental variables, particularly when sampling costs are intrinsically high. Various ranked set estimators are considered for the population mean and contrasted in terms of their efficiencies and useful- ness,...

    We study the asymptotic properties of the number of open paths of length n in an oriented ρ-percolation model. We show that this number is e n α( ρ)(1+ o(1)) as n→∞. The exponent α is deterministic, it can be expressed in terms of the free energy of a polymer model, and...
