abstract="A value of time has been calculated by calibrating a traffic assignment model to match toll expressway usage in Bangkok. This model was developed to reflect the situation in Bangkok, in which extreme traffic congestion and the resulting suppressed traffic demand are common. The values of time derived for models are considerably higher than those derived from income data using either government statistics or home interview survey data, suggesting the unreliability of statistics obtained in the normal manner. A demand curve for expressway travel was then established by extending this method and applied to forecast use of a proposed expressway. The curve derived from the model suggests a demand shift (an upward and clockwise shift of the demand curve) in the future with declining demand elasticity with respect to toll levels as a consequence of increased traffic congestion and real value of time.
