DYNAMIC TRAFFIC EQUILIBRIUM WITH DISCRETE/CONTINUOUS ECONOMETRIC MODELS

The primary objectives of this paper are the development and demonstration on an operatonal dynamic traffic equilibrium model. The paper takes a theoretical and empirical approach that departs somewhat from the evolutionary course of the literature. Three key components of the paper distinguish it from previous efforts: 1) departure time is viewed as continuous instead of discrete; 2) travelers are assumed to have some control over vehicle speed and consequently trip travel time; and 3) spatial and temporal equilibrium is defined in a classic economic sense and operationalized through the constraints imposed by the discrete/continuous econometric structure. The paper begins with an overview of the empirical setting that will form the basis of subsequent model estimation and simulation experiments. This is followed by a presentation of the demand model structure, a discussion of specification issues, and estimation results. Equilibrium definitions are then specified and an appropriate equilibrium algorithm is outlined. The dynamic equilibrium model is then demonstrated through numerous simulation experiments and, finally, a summary of findings is made and appropriate conclusions are drawn.
