This paper describes a two-stage equilibrium travel demand model. The unique feature of this model is that it takes time-of-day traffic counts instead of land use and demographic data as inputs to derive spatial and temporal travel demand patterns. The first stage of the model is a trip matrix estimator based on traffic count; the second stage is an elastic-demand network flow estimator, which recognizes latent demand shifts while performing mode split, time-of-day split, and traffic assignment in a multilevel equilibration. The main purpose of this paper is to describe model development, algorithm design, and software implementation experiences. An example application illustrates how the model is used to evaluate multiclass, multimode, and multiperiod network flow patterns for sketch planning purposes.
