THE TRADITIONAL EQUILIBRIUM MODEL DEALS WITH EXTREME CONDITIONS FROM A BEHAVIORAL VIEW POINT IN THE SENSE THAT ALL ROUTES UTILIZED BETWEEN EACH 0-D PAIR MUST HAVE THE SAME ROUTE COSTS, AND ROUTES WITH HIGHER COSTS ARE NEVER USED. SUCH CONDITIONS ARE VERY SIMPLISTIC AND NOT SUPPORTED BY THE RANDOM UTILITY THEORY. THIS STUDY FOCUSES ON A TRIP MAKER'S ROUTE CHOICE BEHAVIOR ON A ROAD NETWORK. THEY ARE THE PURPOSE OF THIS PAPER TO ASSAY THE DRIVER'S ROUTE CHOICE BEHAVIOR BY MAPPING OUT METHOD, AND TO COMPARE THE STOCHASTIC NETWORK EQUILIBRIUM MODEL PROPOSED BY FISK WITH THE PROBABILISTIC TRAFFIC ASSIGNMENT METHOD PROPOSED BY DIAL.
